The following additional accessories are available from your dealer. Refer to a Futaba catalog for more information:
•
•
•
•
•
•
•
•
CAMPac Memory module — the optional DP-16K CAMPac increases your model storage capability (to 20 models
from 10) and allows you to transfer programs to another 3PK transmitter. Note that data may not be transferred to/from
any other model of transmitter (3PJ, etc).
CAUTION - Insertion of a CAMPac containing data of a different transmitter type (ex: 3PJ) will result in
a complete CAMPac data reset and loss of all data.
Transmitter battery pack — the NT8F700B (700mAh) transmitter NiCd battery pack may be easily exchanged with a
fresh one to provide enough capacity for extended sessions.
Y-harnesses, servo extensions, etc – Genuine Futaba extensions and y-harnesses, including a Heavy-Duty version with
heavier gauge wire, are available to aid in your larger model and other installations.
5-cell (6.0V) receiver battery packs. All Futaba equipment (except that which is specifically labeled otherwise) is
designed to work with 4.8V (NiCd 4 cells) or 6.0V (NiCd 5 cells or alkaline 4 cells). Using a 6.0V pack increases the
current flow to the servos, which accelerates their rate of response and their torque. However, because of this faster
current draw, a 5-cell battery pack of the same mAh rating will last approximately ¾ the time of a 4-cell pack.
CAUTION - NOTE that HRS receivers require 6.0 volts and will not operate with 4.8V 4-cell packs.
Gyros – a variety of genuine Futaba gyros are available for your specialized model needs.
FailSafe: the FS1 FailSafe may be used with standard PPM/FM receivers to return throttle to idle in case of a loss of signal,
similar to the FailSafe function of PCM/HRS receivers. NOTE that HRS receivers can not operate with the FS1.
Battery Holder (Transmitter): This battery holder is necessary when using the transmitter with dry cell batteries. For a
description of how to install the battery holder to the transmitter, see “NiCd Replacement” on page 54.
DSC cord – allows setup and testing without transmitting. Requires DSC compatible receiver and DSC cord. With transmitter
and receiver off, plug cord into transmitter and then into receiver battery slot. Turn on receiver power. All programming and
setup may be done in this matter without transmitting. See glossary for a list of DSC-compatible receivers.

MODULE: 75PK-FM
Module may be easily removed and a module on a different channel (or even band) reinserted to change the
transmission frequency or band.
Module transmits FM (PPM), HRS-FM (HRS) and PCM. No need for a second module.
Module is protected under the RF module cover on the top of the radio.
All transmission circuitry is included in the module, so no retuning is needed when changing channels or even bands.
Frequency band is changed by inserting a module on the proper band, including for international use.
In North America it is against FCC regulation to change the crystal within the transmitter module to a different
channel. All such transmitter crystal changes must be performed by a certified radio technician. Failure to properly
tune a system to its new channel may result in decreased range and may also result in interference to other types of
frequency users on adjoining channels.
The FSS synthesized module for the 9Z family of radios is NOT compatible with the 3PK.
DISP displays instead of RF when main power is on and module is not installed.
It is normal for the module to get slightly warm during use.
Non-Futaba brand modules are not FCC certified for use with this radio and therefore are against FCC regulation to use.
Do not use other modules in the 3PK or the PK module in other radios.
Do not operate transmitter with module in and power switch on, while antenna is collapsed. Always extend antenna
if transmitting.

RECEIVER: R203HF or R113iP
•
•
•
The receiver included with your system is a high-sensitivity narrow-band
single-conversion receiver.
Any Futaba narrow band PPM(FM) receiver (all produced after 1991) on the
correct band and frequency may be used.
Any Futaba PCM 1024 receiver on the right band and frequency may be
used. (all 1024 receivers say PCM1024; receivers which say PCM but not 1024
are 512 resolution and not compatible).
Any Futaba HRS-FM receiver on the right band and frequency may be used. At
the time of this writing, only the R203HF is available. HRS receivers require 6.0V
batteries and digital servos, including for throttle.
In North America the receiver included with this system may have its frequency changed by simply changing the
crystal, as long as it remains in the same band. You may change anywhere from channel 61 through 90 in the 75MHz
band or A1 through A6 in the 27MHz band without requiring retuning.
NEVER attempt to change a receiver’s band by simply changing crystal (IE removing a 27MHz crystal and inserting
a 75MHz crystal). A receiver that has a crystal installed from a different frequency band without retuning will NOT
receive properly and will have dramatically decreased range if it responds at all.
•
•
SERVOS:
All Futaba PPM(FM) and PCM1024 receivers are compatible with all
J-plug Futaba servos, including retract, winch, standard and digital servos.
•
NEVER use non-digital servos with HRS
receivers. Severe damage to all electronics may
result, including the possibility of a fire. Only
digital servos may be used with HRS receivers,
including for throttle.
GETTING TO KNOW THE TRANSMITTER
Display switch
• If the display switch is turned on without turning on the power switch, programming is possible without emitting
radio waves.
If power switch is turned on while display switch is on, transmitter will transmit, which
will interfere with other users operating on the same frequency. Always be sure you have
control of your frequency prior to turning on the primary power switch.
• LCD screen contrast can be adjusted (See SYSTEM, p. 13.)
• LCD may be difficult to read due to temperature change when exposed to direct sunlight
for more than a few minutes at a time, extreme heat, cold, or humidity.
• Always use only the display switch unless you want to transmit to your receiver and you
have control of the frequency.
• Transmitting with the antenna collapsed may damage the module.
Power switch turned on: Beep confirmation sound is generated and the initial screen shown below appears.
DPAC
(if CAMPac installed)
• Total timer display (H:M) (see TIMER p. 30) and battery
voltage display
BLHT
•
Model
name (10 characters) Futaba name can be changed to

User name display: When the END button is held down for 1 second or longer at the initial screen, the Futaba logo and
user name are displayed for about 2 seconds.
Digital trim operation
Trim Push
Button
Switches
Trim Lever
• Default assignments may be changed in FUNC-DIAL (pp. 34-35).
•
•
•
•
•
Features assigned to DL1, 2, 3, and DT1, 2, 3 are displayed at all
times on right side of LCD screen.
Digital trims can be used in 2 ways:
Operating by the lever: Push the lever to the left or right (up or down).
Operating by push button switch: Press the push button switch in
the desired direction.
The current position is displayed on the LCD screen in the bottom
three rows of the list.
Each step is indicated by a tone.
When the trim exceeds the maximum trim adjustment range, the beep
will change and the servo will not move any farther. Return to the
neutral position (center) by pressing both the push button switches
simultaneously for about one second.
Trim lever adjustments have no effect on the maximum servo travel.
This prevents the linkages from binding when adjustments are made.
•
•
Digital grip dial operation
• Default assignments may be changed in FUNC-DIAL (pp. 34-35).
•
•
•
•
•
DL1
Features assigned to DL1, 2, 3, and DT1, 2, 3 are displayed at all
times on right side of LCD screen.
Initial settings: DL1=Steering Dual Rate, DL2=ATL
Operate the dials by turning them. The current set value is displayed
on the LCD screen.
A beep is made at each step.
When the maximum position is reached at each side, the length of the
beep changes. Thereafter, the set value does not change.
Remember, the dials are digital so the position of each dial is
remembered for each model separately.
DL2
Transmitter Checks Prior to Each Use
1. Turn on transmitter power.
2. Check the display screen for model name/number to
ensure you are working with the correct model.
3. Check the display screen for “RF”.
a. If RF is not displayed, check crystal/module installation.
Be sure module is clipped firmly into transmitter.
b. If RF is intermittent or non-existent, send for service
immediately.
4. Check the display screen for proper modulation to
match the receiver in this model.
a. FM receivers, such as R123F, must be set to PPM.
b. PCM1024 receivers, such as R113iP, must be set to PCM.
c. HRS-FM receivers, such as the R203HF, must be set to HRS.
5. Confirm function assignment. Notice the 6 features
listed in the box on the right of the screen, which shows
you the features assigned to the digital dials and digital
trims respectively, and their current settings.
6. Check trim, dual rate and ATL operation/positioning.
a. Steering trim is defaulted to the DT1 trim lever above
the steering wheel. Operate the lever and make sure
the marker moves on the ST graph. If default has
been changed, test steering trim in its new location.
b. Repeat test for throttle trim, defaulted to DT2.
c. Repeat test for steering dual rate, defaulted to DL1, at
the grip of the transmitter.
d. Repeat test for ATL, defaulted to DL2, below DL1.
INSTALLATION
Receiver and Servo Connections
When connecting and installing the receiver and servos, read all safety precautions in the appendix.
Installation When an ESC is used (MC800C)
Installation For Gas Powered Models
B/C port is for the receiver battery or a DSC cord. For information on DSC cord, see p 5.
Receiver Notes
DO NOT cut or fold the receiver antenna wire back on itself — cutting or folding changes the electrical length
of the antenna and may reduce range. Secure the antenna as instructed in your model's manual. You may run the antenna
inside of a non-metallic housing within the model, but range may suffer if the antenna is located near metal or carbon fiber
parts. Be sure to perform a range check before using.
When you insert Futaba servos, ESC, switch or battery connectors into the receiver, note that each plastic housing
has an alignment tab. Be sure the alignment tab is oriented properly before inserting the connector. To remove a
connector from the receiver, pull on the connector housing rather than the wires.
If your servos are too far away to plug into the receiver, use an extension cord to extend the length of the servo lead.
Additional Futaba extension cords of varying lengths are available from your hobby dealer. Always use an extension of the proper
length. Avoid plugging multiple extensions together to attain your desired length. If distance is greater than 18” or multiple or high
current draw servos are being used, Futaba Heavy-Duty servo extensions are recommended.
Receiver Vibration and Waterproofing
The receiver contains precision electronic parts. Be sure to avoid vibration, shock, and temperature extremes.
For protection, wrapping the receiver in foam rubber or other vibration-absorbing materials is ideal.
Mounting with double-sided tape is the next best option: It is also a good idea to waterproof the receiver by placing it
in a plastic bag and securing the open end of the bag with a rubber band. If you accidentally get moisture or fuel inside the
receiver, you may experience intermittent operation or a crash. If in doubt, send the receiver for service.

Using the 3PK’s Functions:
The 3PK offers not only the most comprehensive menu of features available to provide optimum performance, but also
quick-access to utilize your favorite features. 3PK offers “Menu Selection” for onscreen lists of available features, and a
specialized, fully customizable version of “hot keys” called “Direct Selection.” (Don’t worry if terms seem overwhelming.
Check the glossary and read on to get more familiar with new terms.)
Menu Selection
Each function is easily selected from the function menu displayed on the LCD screen with the select key.
Three sets of function menus are available to match the level of use. To select the level for each model, use the Level
Select function (page 12). Note that functions are in different locations depending on the level selected. This is done
to keep level 1 simple, and keep related functions together on the higher levels.
•
•
• Level 1 (LV1): For the new user, basic functions only.
• Level 2 (LV2): Race-ready, including most popular racing
setup features.
• Level 3 (LV3): All functions can
be selected. (For expert driver)
Direct Selection
The Direct Selection screen allows quick access to 6 user-selectable functions with just 2 keystrokes:

Model Selection MDL-SEL
Levels LV1, LV2, LV3
DEFINITION: Selects from the 10 model memories stored within the transmitter,
or additional model memories in the optional CAMPac ©.
AVAILABLE FOR:
10 models in transmitter memory
Optional additional memories, 10 per CAMPac © (see p. 5).
•
•
ADJUSTABILITY:
Models M1-M10 within the transmitter, E11-E20 from optional CAMPac ©
Stores complete model setups with all functions separate per model (except
settings within SYSTEM).
•
•
INTERACTIONS:
Each model memory is a completely separate setup, and allows adjustment of all functions within each separate
model memory (except SYSTEM functions).
Each model memory may be set to a different modulation. If a model memory of a different modulation is selected,
the transmitter must be turned off and back on to change the modulation.
Example: Model 1 is HRS with R203HF receiver. Model 2 is FM with R133F receiver. Select model 2 and
close the menu. Note that HRS is still displayed on screen. Turn transmitter off and back on. Modulation now
shows PPM and will communicate with the R133F or other FM receiver. (If you do not cycle the power on the
transmitter, it cannot communicate with the PPM receiver. See MOD-MODE, p. 16.)
Each separate model memory may have a different level selection, so that simple models have only LV1 menu, with
LV2 and LV3 for other, more complex models.
To make a copy of one model memory for setting up another, similar model, or for experimentation, change
LEVEL-SEL to LV2 (p. 12), and use MDL-COPY (p. 33).
•
•
•
•
•
DESIRED END RESULT: Select a specific model’s setup within the radio or CAMPac data storage.
CAUTIONS:
Never remove the CAMPac © with the power switch on.
If a CAMPac-stored model (E11-20) is in use when the transmitter is turned off, and then the CAMPac is
removed, “SELECT ERROR” will be displayed on screen and model M1 will be automatically selected. Use model
select to select the desired model.
The transmitter does not recognize one CAMPac as being different from another. Model E11 is the first model
in the CAMPac currently in the port, regardless of what CAMPac was last in the port. (Imagine inserting a
floppy disk into your PC with a file on it labeled car1.doc. Close the file, remove the floppy, and insert another
floppy which also includes a file called car1.doc. Your PC doesn’t know or care that they may be different files;
it simply opens the file named car1.doc.)

Modulation Select MOD-MODE
Levels LV1, LV2, LV3
DEFINITIONS:
Modulation select: Chooses the modulation (language) used by the transmitter to
give instructions to the receiver.
PPM: Pulse Position Modulation, commonly called “FM”. Transmitted via FM,
not encoded.
PCM: Pulse Code Modulation. Transmitted via FM, but encoded for increased
noise resistance. Includes FailSafe programming. (See p. 17.)
HRS: High Response System. Transmitted via FM at accelerated rate; includes
FailSafe programming. (See p. 17.)
FM: Type of transmission of data. (Similar to FM car radio.) Used for PPM,
PCM and HRS.
AVAILABLE FOR: Each individual model memory separately.
•
•
•
•
•
ADJUSTABILITY:
PPM (Pulse Position Modulation, commonly called “FM”) for FM receivers such as R133F
PCM (Pulse Code Modulation, 1,024 step resolution) for PCM receivers such as R113iP
HRS (High Response System) for HRS receivers such as R203HF
•
•
•
INTERACTIONS:
Modulation is set separately for each model. One model can be PCM and another HRS, and still another PPM(FM).
Modulation is not reset when a Model Reset is performed.
Modulation is stored for each specific model. Turn transmitter off/on if new model is in different modulation.
Both transmitter switches MUST be turned off and back on for a change to take effect. If transmitter is not turned off
after modulation is changed, it continues to transmit in the last modulation. Display shows the current method of
transmission under NOW OPERATION and the modulation that will be used as soon as the transmitter is turned off and
back on under MEMORY.
•
•
•
•
DESIRED END RESULT: Change transmitting “language” so the receiver can understand the transmitter’s instructions.
CAUTIONS:
While there are 3 types of modulation (4 if you include AM, not supported by 3PK), all are transmitted on the
same frequency band. NEVER attempt to operate more than one model on the same frequency at the same time.
Transmitter must be turned off and back on for change to take effect.

HOLD: Maintain the last instruction provided by the transmitter before clean
signal was lost.
SET: Position servos are to be moved to if FailSafe activates.
BATTERY F/S: When “on” the receiver will move the throttle servo to the preset
FailSafe position when the receiver battery is low. Release and pull trigger to
reactivate throttle for approximately 30 seconds.

•
AVAILABLE FOR Steering, Throttle, Channel 3, only with HRS/PCM receivers
and HRS/PCM modulation settings (see MOD-MODE, p. 16).
ADJUSTABILITY: Hold or set (to go to a preset position).
INTERACTIONS:
FailSafe operates only during interference or loss of transmitter signal.
Modulation is not reset when a model reset is performed, but the FailSafe settings are reset.
•
•
DESIRED END RESULT:
FailSafe: Provide receiver pre-recorded instructions of how to perform in the event it does not receive clean, clear
transmission from a transmitter on its channel in Futaba PCM1024 language.

End Point Adjustment EPA
Levels LV1, LV2, LV3
DEFINITION: End point, commonly called EPA or ATV, adjusts (shortens or
lengthens) the total travel of the servo. For example, a steering servo travels 60°
each way. Decreasing the right EPA to 50% results in a steering servo that will
move 60° to the left but only 30° to the right.
AVAILABLE FOR: Steering, throttle, channel 3.
ADJUSTABILITY: 0-120% on all 3 channels. Default: 100%.
18
INTERACTIONS:
EPA is a primary function. EPA’s should be set prior to doing any other programming and not adjusted (except for
servo replacement, etc.) once other programming has been set. If EPA is adjusted after features such as dual rates,
ATL, mixing, etc, the other functions must be readjusted based upon the new EPA.
EPA is not limiting or absolute. Other programming functions can override the end point set by EPA. Always double
check for binding after adjusting:
Sub trim (all channels)
Program mixing slave side (all channels)
Tilt mixing (steering, channel 3)
Idle up (throttle)
Throttle preset (throttle)
ATL trim (set ATL trim dial center prior to adjusting throttle channel EPA.) (LV3 only.)
EPA is not tied to any mixing. EPA adjusts each individual servo regardless of brake mixing, boat mode mixing, etc.
NOTE: When EPA is increased to maximum (120%) but more servo travel is needed, the servo’s motion can be
increased with programmable mixing, up to the servo’s physical limits. (See programmable mixes, pp 40-41.)
Interaction Example:
Original setup:
Steering servo linkage allows 30° of servo rotation to the left.
Steering EPA is adjusted to 90%, creating 27° of left travel.
Steering dual rate is adjusted to 50%, or 13.5° of travel.
Adjusting EPA to 120% results in 36° of left travel; dual rate now provides 18° of travel, not 13.5°.
Steering dual rate adjusts the servo’s total travel as if EPA was adjusted. ATL adjusts braking travel. Both can be
assigned to dials (see FUNC-DIAL, pp. 34-35).

DESIRED END RESULT:
All channels: Servo is not binding or chattering, trying to move the linkage farther than it is physically able.
All channels: Servo moves the attached pushrod just enough, creating the desired maximum servo movement.
All channels: Linkage does not stick, bind, or catch on anything on the vehicle.
Steering: Full right and full left turns result in the desired turning radius.
Channel 3: Function moves the desired distance when full up/down, left/right or pressed/unpressed button are applied.
•
•
•
•
•
CAUTIONS:
Servo binding drains receiver batteries very quickly and may result in a loss of control.
More is NOT always better! Start with the desired steering throws recommended for your vehicle.
Always check for binding and servo “chatter” prior to each use.
Always set dual rates, sub trims, and all other functions to their defaults prior to adjusting EPA.

Exponential (ST-EXP, TH-EXP)
Levels LV1, LV2, LV3
DEFINITIONS:
Exponential adjusts the sensitivity of the servo around the neutral position.
Exponential creates a true curve, not a hard climb to a certain point then a softer
climb from there. Negative exponential makes the servo less responsive around
center; positive exponential makes the servo significantly more responsive
around center. Only exponential is available for steering and braking.
TH-EXP offers far more than just exponential for forward: it also offers a 5-point
throttle “curve” and a Variable Trace Rate (VTR) option.
VTR: Variable Trace Rate is basically a 3-point line, where one point may be
raised or lowered, forming two straight lines, and where the user can select the
point where the line breaks into two.
The “curve” function offers 5 points along the range of the servo, and draws
straight lines of response between each point. It is not a true curve, as is
exponential, and there are noticeable steps in the responsiveness as each rate of
response is entered.

AVAILABLE FOR: Steering (ST-EXP), Throttle (TH-EXP)
ADJUSTABILITY:
Range:

Throttle: Forward and Braking
Steering: Left and right
Types: (TH-EXP forward only) Variable trace, curve, or exponential curves.
May be assigned to a dial for on-the-track adjustability. (See FUNC-DIAL, pp. 34-35.)
•
•
•
•
•
INTERACTIONS:
Exponential affects the servo’s response around center, and affects all built-in and programmable mixing functions
such as throttle acceleration, brake mixing, ABS, etc. All mixing functions respond based upon the position the
transmitter is telling the servo to go to, not the amount of trigger being pulled or wheel turned.
EPA affects the total travel of the servo, and exponential is proportional to and affected by that total travel.
AT-START, TH-SPEED, TH-ACCEL and other features interact with this function. For example, a very high VTR rate will
result in rapid acceleration early in the trigger movement. Therefore, the engine reaches wide open at, for example,
half throttle trigger. This may make it seem as though Speed Limiter programming is needed when you really should
adjust the VTR rate to create a more normal throttle response.
•
•
•
DESIRED END RESULT:
Positive exponential makes the servo move farther for the same amount of input when around neutral (for sharper
steering when small inputs are given, for example).
Negative exponential makes the servo move less for the same input when around neutral (to make a nitro engine’s response
to the throttle trigger smoother and more consistent between the first 1/4 of the trigger and the last 1/4 of the trigger.)
•
•
CAUTIONS:
Too much positive exponential can make the model so overly sensitive it may be impossible to control.
Too much negative exponential can make the model so non-responsive, your inputs may be too little too late,
resulting in a crash.
Too high of a rate on a throttle VTR will result in the engine reaching full throttle well before the trigger is at full
throttle, which may result in wheel spin, especially upon acceleration.
•

sooner, or slower, on a smoothly linear response?

Sub-Trim SUBTRIM
Levels LV1, LV2, LV3
DEFINITION: Fine tuning adjustment for the center point of each servo. Similar to
using electronic trims on the radio, but subtrim moves the entire servo’s travel
rather than just sliding the servo left/right within the total travel. The setting is
stored within the programming and the onscreen displays continue to show neutral.
AVAILABLE FOR: Steering, throttle, channel 3
ADJUSTABILITY:
Steering: left 100 to right 100
Throttle: brake 100 to throttle 100
Channel 3: -100 to +100
May be assigned to a dial/trim. (See FUNC-DIAL, pp. 34-35.)
•
•
•
•
INTERACTIONS:
ALWAYS adjust your digital trims back to neutral prior to adjusting your subtrim. Then adjust the subtrim until the
servo is at the desired location without needing any digital trim.
Subtrim adjusts the entire range of the servo to one side or the other; it does NOT adjust the servo’s center point
toward one end of the total travel like digital trims.
Subtrim affects the neutral point for the servo for all other functions.
•
•
•
DESIRED END RESULT: Fine-tune the servo’s center point to correct for minor linkage problems.
CAUTION: The range of subtrim is limited. Always adjust linkages to get the servo’s center as close to the desired
location mechanically and only use trim functions as absolutely necessary.
GOAL:
STEPS:
INPUTS:
Moving the steering servo arm one tooth
on the servo results in a slight right turn;

LV2 FUNCTIONS for the Race-Ready Driver
Levels LV2, LV3 Only
Servo Maximum Speed Limiter (ST-SPEED,TH-SPEED)
DEFINITION: Speed Limiter decreases the maximum speed of the servo. This
may be adjusted individually for turning and returning the servo to neutral
(steering), and for high and low throttle settings.
A servo which responds too rapidly to a full-wheel input may cause the vehicle to
oversteer; to compensate many drivers steer too slowly, resulting in understeer
and not completing a clean corner. Others slow down to make the model more
controllable, losing valuable seconds. Speed Limiter helps in both these cases.
Similarly, applying throttle too suddenly results in wheel spin and wasted energy.
It may also cause a nitro engine to stall.
AVAILABLE FOR: Steering (ST-SPEED), Throttle (TH-SPEED)
ADJUSTABILITY:
1% (slowest possible response) to +100% (normal response)
On input and return (ST-SPEED only); High speed and low speed (TH-SPEED only)
On/off switch may be assigned for TH-SPEED only. Switch selection made in FUNC-SW (see pp. 34-35).
Throttle speed and steering turn/return may each be assigned to a dial. See FUNC-DIAL (pp. 34-35).
•
•
•
•
INTERACTIONS/COMPARISONS:
Increasing EPA decreases the rate at which a servo reaches a given point mechanically; therefore, adjusting EPA will
also adjust the actual rate of response of that servo.
Negative exponential softens how far the servo responds to a given input vs. how fast. Either is used to settle a
“twitchy vehicle”, but the driver must first determine if the servo is moving too far, or simply too quickly.
ABS pulsates the amount of brake given for a certain input to avoid overbraking and skidding the entire time brake
is applied. Speed Limiter slows the brake command and decreases skidding only when brakes are first applied.
Throttle acceleration gives a significant sudden movement of the throttle servo only when the trigger is first moved;
Speed Limiter would slow that quick step off idle and diminish the effectiveness of acceleration. Thus, modifying
Speed Limiter may require adjustments to acceleration, and vice versa.
Auto-start moves/holds the servo to a preset position when the throttle is applied the first time, then allows the servo
to operate through its normal travel for the rest of the run; Speed Limiter slows the performance of the throttle servo
at all times. If the problem is spinning on starts only, then auto-start should be adjusted, NOT Speed Limiter.
Idle-up increases the throttle idle as if throttle trim were applied, and is used to make starting nitro engines easier.
Speed Limiter will only effect how rapidly the engine responds when additional throttle is applied.
ATL adjusts the end point of the braking side only; Speed Limiter affects how quickly that total distance is traveled.
Adjustments to either may require fine adjustments to the other.

ABP: Amount of brake return, how far the braking response is decreased
during the pulses.
DLY: Delay; determines how long the braking is applied before ABS begins

DTY: Cycle duty ratio, sets the proportion of the total cycle spent with brakes
applied full vs. ABP.
STM: Steering mix setup, controls when the ABS is triggered based upon amount of steering input. Designed to
decrease skidding when vehicle is in a turn, and minimize spin outs.

AVAILABLE FOR: Braking only.
ADJUSTABILITY:
ABP: 0 (no ABS) to 100% [Servo goes to neutral (no brake) during pulse].
DLY: 0 (ABS responds immediately) to 100% (1.7 seconds of full brake before ABS takes over).
CYC: 1 (fastest) to 30 (slowest). Default=10.
TGP: 10-100.
DTY: -3 (longest full brake application — most likely to skid) to + 3 (shortest full brake – least likely to skid).
STM: OFF, N10-N100, E10-E100.
MODE:Inhibited, Active but switch is off, Active and switch is on.
Switch assignment can be changed in FUNC-SW (see pp. 34-35).
Each ABS variable can be assigned to dials in FUNC-DIAL (pp. 34-35) for on-the-course adjustability.

INTERACTIONS:
EPA, servo reversing, dual rates, Speed Limiter, acceleration, auto-start, and exponential all interact to create the
overall braking effect.
Brake mixing works with ABS as if only one brake servo were used. No second setup for ABS is required.
Trigger point, steering mix and assigned switch each control ABS. All three must “say OK” for ABS to respond.
•
•
•
DESIRED END RESULT: Model stops as rapidly as possible without skidding.
CAUTIONS:
Careful analysis of the problem causing skids is required to adjust the proper portion of ABS for best results.
Adjustments to EPA, auto-start, expo, speed, brake mixing, vehicle’s suspension, tire compounds, engine
tuning and ATL will all affect the performance of the ABS settings.

INPUTS:
GOAL:
STEPS:
Set up a fairly rapid servo (such as S9402)
on a nitro off-road vehicle, while using LV2.
(If using LV3, select ABS from menu 1.)
(If using LV1, first change level selection.
See p. 12.)
Open and select menu 1.
Desired settings:
Fairly mild return (ABP) 30%
Use ABS if brakes are applied for more
than approx. 1/4 second (DLY): 10%
Pulse quickly (CYCL): 5-7
Use ABS only if braking hard: TGP: 70%
Leave proportion of brake on to brake off
even (DUTY): 0
Leave steering mix off (STM): 0

Set the trigger position where ABS
becomes effective to 70% (TGP).
Leave the difference in brake-on to brakeoff in each cycle to 0 (DUTY).
(Leave at 0.)
Allow ABS to work whether vehicle is
turning or not (STM).
(Leave at OFF.)
View ABS working within the function on
screen to confirm proper setup. (Hint: LV3
users can also view braking activity and
all other servo actions on screen using the
SERVO function.)
Gradually push the throttle trigger to
approximately half brake. Screen should
still read “MODE: ACT (OFF)”.
Push past 70%. Display now reads “MODE:
ACT (ON)” and you can see how brake
commands will be transmitted to the servo
right on the screen.
Close function and menus.
Fine tuning:
If brakes still lock during all stops, analyze the problem, then try:
Increasing ABP so less brake is applied during pulses.
Decreasing DLY so that ABS takes effect more rapidly.
Increasing CYC so the brakes pulse more rapidly, each on/off cycle is shorter.
Decrease the TGP so ABS takes over with less brake application.
Decreasing DTY so that brake off time is longer than brake on.
If brakes lock in turns but are not enough on straights:
Set STM so ABS functions only when turning (ex: E50).
Where next:
NOTE: All of these functions interact with the throttle servo as well and are all interrelated. Adjusting any one may affect the performance of the others, as described in
Interactions for each function.
Adjust the throttle servo’s overall speed (TH-SPEED): See p. 23.
Adjust throttle exponential (TH-EXP): See p. 20.
Adjust throttle servo’s response only immediately around neutral to correct for nitro

Rapid Throttle Acceleration THR-ACCEL
Levels LV2, LV3 Only
DEFINITION: Due to the shape of some nitro engine linkages, throttle servo
movement near neutral results in very little movement of the pushrod. Throttle
acceleration simply jumps the servo from neutral to a portion of the total
available throw whenever the trigger is moved away from center. It does NOT
change the speed of the servo; the servo will jump to the input position at its
maximum possible speed. Unlike exponential, which adjusts the whole throttle
movement into a curve, throttle acceleration simply “jumps” away from neutral
and then leaves the remaining response linear. Accelerate is a pre-programmed
VTR throttle exponential (see p. 20).
AVAILABLE FOR: Throttle and braking separately.
ADJUSTABILITY: 0-100%.
At 100% the throttle servo moves immediately to
approximately 40% of the total EPA.
At 100% the brake servo moves immediately to full brake.
Each setting may be assigned to a dial or trim for on-thetrack adjustability. (See FUNC-DIAL, pp. 34-35.)
•
•
•
INTERACTIONS:
EPA will affect how far the servo moves in the jump. Changes in EPA may require adjusting throttle acceleration.
Brake mixing works with acceleration as if only one brake servo were used. No second setup is required.
•
•
DESIRED END RESULT: Model responds to throttle/brake immediately, similar to an electric car.
CAUTION: High brake settings will result in locked brakes. Adjust throttle acceleration only enough to pick up the
slack in the linkage; then, utilize ABS to fine tune braking performance.
GOAL:

Levels LV2, LV3 Only
Idle-Up IDLE-UP
DEFINITION: Adjusts the throttle’s idle/neutral point, usually used to create a
raised idle, making it easier to start the engine. May adjust either toward higher
idle (U) or toward braking (D).
AVAILABLE FOR: Throttle only.
ADJUSTABILITY:
D50-1, 0, U1-50%. D = brake side. U = throttle side.
Rate may be assigned to a dial or trim for on-the-track adjustability (see FUNCDIAL, pp. 34-35).
•
•
INTERACTION:
Requires switch assignment in the FUNC-SW screen (see pp. 34-35).
EPA does NOT affect the preset position of idle-up.
Idle-up could actually exceed your total EPA. Idle-up obeys only the actual total servo travel and servo reversing, and
no other programmed changes.
•
•
•
DESIRED END RESULT: Throttle servo moves to a preset position when button is pushed and throttle trigger is at
idle. Has no effect at other throttle positions.
CAUTION: If you have to adjust your EPAs after setting up this function, be sure to double check that the pre-set
travel is still what is desired.

Auto-start Throttle Settings and Engine Cut AT-START
Levels LV2, LV3 Only
DEFINITIONS:
Auto-start: A pre-set throttle position, less than full throttle, to be used for the
initial acceleration off the line without having wheel spin. When the trigger is
released, auto-start is turned off and throttle operates normally again.
ATS: Auto-start status.
Engine Cut: Shuts the engine off without having to adjust the throttle trim. Takes
the throttle servo to a preset position when the switch is pressed. (Not available
to models using braking/reverse from the throttle servo. Primarily for boats.)
TG.P: Trigger point at which auto-start is activated.
PRST: Preset throttle servo position when function is activated. Preset is a
“true” preset – it is not a mix or a portion of the EPA. It is truly a
command to move the servo to a set position regardless of other inputs,
including trigger.
MODE: Which function is being utilized at this time. (Engine cut and auto-start can not be used together).
AT&SW: Auto-start is activated by throttle trigger or switch. Switch can be assigned in FUNC-SW (pp. 34-35) and
used to turn on/off the auto-start feature without having to pull or release the throttle trigger to do so.
INH:
Inhibited. Function is electronically inhibited and will not operate until changed to another setting.
SW:
Switch operated. Auto-start is inhibited and engine cut is available. (Assigned in FUNC-SW, pp. 34-35.)
•
•
•
•
•
•
•
•
•
AVAILABLE FOR: Throttle servo only.
ADJUSTABILITY:
MODE: Inhibited, switch only (engine cut), auto-start with switch override (autostart).
ATS: Inhibited, off (not available until set), ready (will activate on next trigger pull), active (operating now).
TGP: Inhibited, 5-95. Default: 5.
PRST: Brake 100-1, 0, Forward 0-100. Default: 0.
Auto-start may be assigned to a switch. Engine cut must be assigned to a switch to operate. (See FUNC-SW, pp. 34-35.)
•
•
•
•
•
INTERACTIONS:
EPA has NO effect on the preset position. The preset position may exceed EPA. Be sure to set auto-start after setting EPA.
Servo reversing DOES change the direction of the preset in this function.
No other function affects the preset except servo reversing.
Trigger position has no effect on engine cut. Engine cut will shut engine to the preset position regardless.
Auto-start must be restarted for each use by going to the auto-start function and pressing the + and – keys together
for one second while ATS is selected, or assigning and holding on a switch. (See FUNC-SW, p. 34-35.)
If throttle triggered, auto-start remains active once started until the throttle trigger is returned to neutral.
•
•
•
•
•
•
DESIRED END RESULT: Avoiding wheel spin on starts and shutting engine off safely.
CAUTION: Remember that preset is not relative to EPA, so always check for binding if other changes have been made.

Timers TIMER
Levels LV2, LV3 Only
DEFINITIONS:
Total Timer: System timer, does not
reset/change with model selection, or
when transmitter is turned off, storing
total use time until it is reset.
Racing Timer: Model-specific timer; types:
Up Timer: Regular stop watch timer.
Counts up from 0 until stopped.
Runs consecutively until reset with
model selection or lap reset.
Down Timer: Count-down timer.
Counts negatively once desired time
is passed (below 0). Runs consecutively until reset with model selection or lap reset.
Lap Memory Timer: Acts as a count-up timer, storing each lap and starting a new lap each time button is pressed,
while also maintaining a total run time count-up alarm, with a pre-alarm warning time. Stores up to 100 laps,
visible on LAP-LIST (see p. 31). Has a 3-second safety window where button press does not reset the lap.
Lap Navigate Timer: Count-up timer which alarms at a set total run time, but also has a navigation alarm which
alarms every set interval (desired lap time), and then restarts the navigation alarm countdown on each button press
or upon passing each navigation alarm time. (Example: 4 minute track race, desired lap time is 30 seconds. Nav
alarm goes off if lap counter is not pressed before 30 seconds, then again after another 30 seconds, and so on until
4 minutes.) Great for practice-runs and working toward a target track time. Does NOT store individual lap times.
LAP START: Switch assignment required to indicate start/stop, or the end of each lap in lap navigate and lap memory timers.
LAP RESET:Switch assignment required to end timers and reset them to be used again.
RUN:
Timer is currently running, and displays total run timer, tracking total race time regardless of individual laps.
STP:
Timer is stopped.
RST:
Timer reset. Stops running timer, resets run timer, stores last lap to memory.
RDY:
Trigger-ready state. If set to ready, timer begins with trigger pull, doesn’t require lap start button to be pressed
to begin timer; however, lap button still needs to be pressed to store each lap. Trigger activity has no effect after
starting the timer.
LAP:
Current lap number.
No.:
Number of laps stored and ready to display.
TIME:
Current running lap time.
NVALM: Number of times the navigation alarm went off, indicating you exceeded your target lap time.
ALRM:
Total run time prior to desired alarm.
PRAL:
Pre-alarm, warning that desired time is approaching, beeps once every second until alarm time is reached.

• Response direction:
• Normal or reversed for all dials/trimmers, and switch 3.
• Normal or alternate for switches 1 and 2.
INTERACTION:
If multiples switches/dials/trims are assigned to do the same job, their settings are combined up to the limits of the
function. For example, assigning steering trim to both DT1 and DL1 means moving either adjusts the trim from the
current position up to the maximum available trim. (Total trim available is still the same, not doubled.)
Digital: Since the dials and trims are digital, their physical position does not matter to the model memory. If a dial or
trim is bumped when both switches are off, no change is made to the position remembered in the memory. For
example, turn on the display. Note the steering trim position shown on screen. Turn the display off. With the display
off, press the digital trims. Now turn the display back on. Note that the trim has not changed. The same is true for the
digital dials, meaning no more need to try to “store” or “set” the dial positions before changing model memories to
avoid unintentional changes in your other models!

LV3 FUNCTIONS for the Expert Driver, Boats or Complex Models
Level LV3 Only
Programming Adjustment of Throttle ATL ATL
DEFINITIONS:
ATL, electronic: (Adjustable throttle limiter) Adjusts total travel available to the
braking side of the throttle servo, similar to adjusting EPA, but allows adjustment
“on the fly” when ATL is assigned to a dial. When brake mixing is used in the
unmixed mode, this adjusts the rear brake servo without changing amount of braking
to front brake servo.
•
• ATL, mechanical: Decreases the physical distance the brake trigger can move.
See p. 51.
AVAILABLE FOR: Braking only.
ADJUSTABILITY:
RATE: 0 (no braking at all) to 100% (same as EPA). Default: 100%.
Rate adjustment: May be easily adjusted while driving (if assigned to a dial/trim, see FUNC-DIAL, pp. 34-35). Default
assignment is to gripper dial 2.
•
•
INTERACTION: EPA affects total travel available to the servo. ATL is directly proportional to EPA.
DESIRED END RESULT: Quickly adjust overall braking sensitivity, including with a dial while driving on the track.
CAUTION: Dial 2 is assigned for ATL adjustment as a default, even if user does not realize it.
GOAL:
STEPS:
While using LV3:
Reassign the ATL adjustment to digital
trim 1;
Adjust the ATL setting from 100% to
20% (with the digital trim centered).
(If using LV1 or LV2, first change level
selection, see p. 12.)
Use FUNC-DIAL to assign ATL to digital
trim 1.

37
Steering Dual Rate ST-D/R
Level LV3 Only
DEFINITIONS:
Dual Rate, or primary dual rate: Decreases the vehicle’s steering sensitivity
across the entire range. Equivalent of decreasing steering EPA by that percentage.
Assigned to grip dial 1 as a default to allow on-the-course adjustments. If grip dial
is unassigned, dual rate may still be adjusted on-screen. Dual rate is always active,
except when the 2nd dual rate switch is pushed. (3PK’s dual rate is the same as the
9Z’s AFR, and the first rate of dual rate in other aircraft style radio models.)
Second Dual Rate: A second while-driving rate of servo response, available
with the push of a switch. The 2nd dual rate is meant to be used to temporarily
have more/less servo travel available without having to readjust the dual rate
dial. Second dual rate is proportional to the EPA not the primary dual rate.
Examples: Used for getting away from walls, crashes, a single hairpin turn on an
otherwise non-technical track.
•
•
AVAILABLE FOR: Steering only.
ADJUSTABILITY:
RATE: 0 (no steering at all) to 100% (same as EPA). Default: 100%.
Switch assignment (to change from primary dual rate to second dual rate): Must be set using FUNC-SW, see pp. 3435. Default: no dual rate switch assigned; 2nd dual rate is not usable until a switch is assigned.
Rate adjustment: Both primary rate and 2nd rate adjustments may be assigned to any dial/digital trim (see FUNC-DIAL,
pp. 34-35) to allow adjustment while driving. If no dial/trim is assigned, then adjustments are made only within the
D/R function. Defaults: D/R on dial 1, 2nd D/R not assigned.
•
•
•
INTERACTIONS:
EPA affects total travel available to steering servo. Both dual rates are directly proportional to the total EPA.
Exponential adjusts how much the servo is moved around center without having any effect on the servo travel at full
stick; dual rate uniformly decreases the servo’s movement all along the travel.
Speed Limiter slows how quickly the servo moves to a certain point without decreasing its overall travel rather than
decreasing the servo’s movement to decrease its sensitivity.
•
•
•
DESIRED END RESULT: Quickly adjust steering overall sensitivity with a dial while driving on the track; have a second
travel rate available for unusual situations, such as a crash.
CAUTION: Dual rate is active as a default and is adjusted from normal setting (100%) with dial 1 unless it is
reassigned by the user.

AVAILABLE FOR: channel 3 only.
ADJUSTABILITY: -100% to 0 to +100%. Default adjusts with dial 3, may be
reassigned with FUNC-DIAL (see pp. 34-35).
INTERACTION: Channel 3 position is relative to channel 3’s EPA.
DESIRED END RESULT: Fine tune the channel 3 neutral position. May also be
used to adjust channel 3 to a specific position and leave it there if adjustability
is not assigned to a dial (see FUNC-DIAL, pp. 34-35).

Programmable Mixes PRG-MIX1, PRG-MIX2
Level LV3 Only
DEFINITIONS:
Programmable mixing function: Allows user to create mixing between the
steering, throttle and channel 3 servos. Brake mixing is an example of built-in mixes.
Master: The channel the slave will follow. In brake mixing, the throttle
channel’s braking side.
Slave: The channel that follows the master. In brake mixing, channel 3 (front brakes).
Offset: Amount off center to adjust the mix.
Mix Mode: Selects whether slave moves exactly based upon the master control’s
movement (unmixed) or the master channel’s servo movements after any mixing
(mixed). Brake mixing unmixed means front brakes respond exactly based upon
trigger position while rear braking is changed by ABS, Speed Limiter, etc.
Trim: Sets whether the slave channel is (ON) or is not (OFF) adjusted with the
master when using the master channel’s trim.

Multiple-Servo Brake Mix BRAKE-MIX
Level LV3 Only
DEFINITIONS:
Brake Mix: Used when model has separate front and rear brakes, and they must be
adjusted separately. Uses channel 2 for rear brakes/throttle, channel 3 for front brakes.
RATE: Proportion of total front brake travel applied when full rear brake is applied.
DELAY: Waits to brake either front or rear, allowing the other to brake first.
BALN: Balance. Adjusts the proportion of front to rear braking.
TGP: trigger point. At what amount of trigger the brake mixing takes effect.
MXMD: Mixing mode. Front brakes respond based solely on trigger position
(UNMIX), or other functions’ adjustments to rear brakes, such as ABS, also effect
front brakes (MIXED).
•
•
•
•
•
•
AVAILABLE FOR: N/A
ADJUSTABILITY:
RATE: 0 (no front braking) to 120% (front brake servo moves 20% more than rear brake).
DLY:
0 (no delay) to 100% (maximum delay, about 2 seconds); F (front) or R (rear). Either F or R MUST be 0;
may both be 0.
BALN: 80 (decreased braking) -100% (no change), F or R. Either F or R must be 100%, may both be 100%.
TGP:
10 (front brakes active even with small amounts of brake) – 100% (front brakes applied only when full brake given.)
MXMD: UNMIX (front brake obeys trigger position only); MIXED (front brake obeys all braking mixes).
•
•
•
•
•
INTERACTIONS:
ABS, Speed Limiter, exponential, etc., all affect the rear brake; mix mode MIXED causes them to also affect the front.
Mixing is based upon total EPA of each servo. Example: Rear servo moves 60° at 100 EPA. Front servo moves 40°
at 100 EPA. Rate of 100% moves front servo full 40° when rear servo moves 60°. Rate of 120% means front servo
moves 40° times 120%, or 48°, when rear servo moves 60°.
•
•
DESIRED END RESULT: Model brakes as rapidly as possible without negative handling effects such as squatted shocks, etc.
CAUTION: Unmixed results in the front brake getting drastically different inputs than the rear when functions such
as ABS are used (no pulsing on front).
GOAL:
STEPS:
INPUTS:
While using LV3, setup brake mixing for
1/5th scale offroad vehicle, with front brake
responding 75% as much as rear, with a
slight delay to allow rear brakes to respond
first, no change in balance, front brake on

Boat Mode BOAT-MODE
DEFINITIONS:
Boat mode: Set ups to fit specific needs of boat models rather than cars.
TRG-BRK: Trigger-Brake operation. Shuts off brake side of servo movement for
boats without braking/reverse.
Tilt Mixing: adjusts outboard engine positioning with rudder inputs, and adjusts
rudder with outboard engine adjustments.
Channel 1 > 3: mix from steering (rudder) to outboard. Utilized when the
boat drops too much (or too little) into the water when giving rudder input.
Channel 3 > 1: mixing from outboard to steering (rudder). Utilized
when the torque of the engine has more effect as the boat’s position
changes in the water, causing the boat to yaw left under acceleration.
•
•
•
•
•
AVAILABLE FOR: N/A
ADJUSTABILITY:
TRG-BRK: Normal (brake operates); cut-off (no brake/reverse operation).
CH 1>3 and CH 3>1: -100% (moves exactly opposite) to 0 (no mix) to +100% (moves exactly the same as master.)
•
•
INTERACTIONS:
EPA, steering expo, speed, dual rate, etc., all affect the 3rd channel (master mixing is on and can not be set to off.)
Reversing the channel 1 servo does NOT reverse the channel 3 servo.

Electronic Centering Calibration Adjuster ADJUSTER
DEFINITION: Calibrates electronic positioning to mechanical movement of
controls. Even if you never have a crash, your R/C vehicle needs occasional
alignments and mechanical adjustments to keep it “in tune” and in trim.
Similarly, all transmitters need regular maintenance to keep everything properly
aligned. But unlike all other transmitters which just have to be driven “as is”
until professionally adjusted/repaired, you can temporarily adjust your 3PK to
keep driving as if it were new, then happily wait until your non-racing season
when you can send it for its regular maintenance.
AVAILABLE FOR: Throttle, steering.
ADJUSTABILITY: Neutral and left/right vs. neutral/brake.
INTERACTION: Adjuster affects the mechanical position the radio thinks is center/neutral, and also the end points.
Correcting any minor slippage/wear in the transmitter with adjuster will temporarily correct the out of trim problems until
the radio can be serviced. All programming functions operate based upon the radio’s neutral and full left/right or
neutral/brake positioning.
DESIRED END RESULT: Correct for minor slippage/wear/drift in the steering and throttle to provide like-new performance.
CAUTIONS:
Need for regular service: Slippage is a sign of wear to the transmitter. Be sure to have your radio serviced
regularly (we recommend annually) to check for/service other wear and tear on the radio and also to ensure
proper transmitter tuning.
Correction range: If the adjustment point shown is not close to the default settings (100%, 0, 100%), the system
will not store the new positions, and an error message of “FAIL! NOT CHANGED” is displayed. Retry process. If
data can not be stored, the radio is too far out of alignment to use. Send for service promptly (see p. 4).

MEANING OF SPECIAL MARKINGS
Pay special attention to safety where indicated by the following marks:
DANGER - Procedures which may lead to dangerous conditions and cause death/serious injury if not carried out properly.
WARNING - Procedures which may lead to a dangerous condition or cause death or serious injury to the user if not
carried out properly, or procedures where the probability of superficial injury or physical damage is high.
CAUTION - Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or
physical damage, if not carried out properly.
= Prohibited
= Mandatory
Warning: Always keep electrical components away from small children.
To ensure the safety of yourself and others, please observe the following precautions:
Have regular maintenance performed. Although your radio does not have a battery to protect the model memories,
it still should have regular checkups for wear and tear. In the US, we recommend sending your system to the US
Futaba Service Center annually for a complete checkup and service.
CAUTION - Before Using Your System…
1. ALWAYS be sure the receiver, servo(s), ESC, crystal and connectors are fully connected prior to every operation.
Vibration, which occurs in all models, means regular inspections and maintenance are critical.
2. ALWAYS protect the receiver and NiCd battery from vibration by mounting them in thick double-sided tape or foam.
3. Aquatic users: ALWAYS protect all radio equipment from potential water damage by waterproofing. Send any
equipment subjected to water, fuel or other corrosive materials for testing prior to re-use.
4. NEVER cut or coil your receiver antenna or bundle it with any servo leads, battery wires, carbon fiber, metal or
other conductive materials.
5. ALWAYS keep the receiver antenna at least 1” away from motor/battery/ignition/other wiring carrying heavy current.
6. Electric Users: ALWAYS install the ESC heat sinks such that they can not come into contact with plastic,
aluminum, carbon fiber, or other conductive materials, or a short circuit may occur.
7. ALWAYS operate each servo full distance both ways and check for buzzing, binding, loose linkages, chatter, or
“stepping” in the movement (check for broken servo gears).
8. ALWAYS use the rubber grommets for servo installation, and ensure the servos do not come into direct contact
with the mount or anything that conducts electricity.
9. Electric Users: ALWAYS install capacitors on electric motors to suppress electrical noise.
10. ALWAYS inspect your model for metal-to-metal contact (including while engine/motor is running) which could
create electrical noise and result in erratic system operation.
11. ALWAYS range check your system.
12. NEVER leave the radio system or models within reach of small children. NiCd batteries can be very dangerous
when mishandled and can cause chemical damage.
13. NEVER store your radio equipment and models where they will be exposed to extreme heat or cold, direct
sunlight, high humidity, large quantities of dust, steam or condensation.
14. NEVER expose the plastic parts of your radio system to raw fuel, oil, exhaust, water.
15. NEVER touch the engine, motor, speed control, or any other part of the model which generates heat during
operation until the model is not operating, has been fully turned off and allowed to cool. These parts may be very
hot and can cause serious burns.
16. ALWAYS display a frequency flag when operating your model.
17. NEVER operate this R/C system when you are tired, not feeling well, or under the influence of alcohol or drugs.
18. NEVER operate near other radio control activity areas, on any ponds or lakes where rowboats or swimmers are
present, or near high tension power lines or communications broadcasting antennas.
47
Charge the batteries! (See Caring for your NiCd batteries, p. 49, for details.) Always recharge the transmitter and
receiver batteries for at least 8 hours before each session. A low battery will soon die, causing loss of control and a
crash. When you begin your session, reset your radio's built-in timer, and during the session pay attention to the
duration of usage.
Stop operating your radio long before your batteries become low on charge. Do NOT rely on your radio’s low
battery warning systems, intended only as a precaution, to tell you when to recharge. Always check your
transmitter and receiver batteries prior to each use.
Before operating, make sure that your frequency is not already in use, and secure any frequency control device
(pin, tag, etc.) for that frequency before turning on your transmitter. It is never possible to operate two or more
models on the same frequency at the same time. Even though there are different types of modulation (AM, FM,
PCM) and brands, only one model may be operated on a single frequency at any one time.
To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:
1. Position throttle at idle, or otherwise disarm your motor/engine.
2. Turn on the transmitter power and allow your transmitter to reach its home screen (if applicable.)
3. Confirm the proper model memory has been selected (if applicable.)
4. Fully extend the transmitter antenna.
5. Turn on your receiver power or speed control power switch.
6. Test all controls. If a servo operates abnormally, don’t use until you determine the cause of the problem. (For PCM
and HRS systems only: Test to ensure that the FailSafe settings are correct by waiting at least 2 minutes after
adjusting; then, turn the transmitter off and confirm the proper servo movements. Turn the transmitter back on. See
page 17 for details on FailSafe functions.)
7. Complete a full range check.
8. After use, bring your throttle to idle, engage any kill switches or otherwise disarm your motor/engine.
9. Turn off receiver power.
10. Turn off transmitter power.
If you do not turn on your system in this order, you may damage your servos or control surfaces, flood your engine, or in the
case of electric-powered or gasoline-powered models, the engine may unexpectedly turn on and cause a severe injury.
If you place your transmitter on the ground, be sure that the wind won’t tip it over. If it is knocked over, controls
may be accidentally moved. Also, damage to your transmitter may occur.
Before running the model, be sure to extend the transmitter antenna to its full length. A collapsed antenna will
reduce your range and cause a loss of control. Try to avoid pointing the transmitter antenna directly at the model, since the
signal is weakest in that direction.
Don’t operate in the rain, drive unprotected electronics through puddles or use when visibility is limited! Water or
moisture may enter the transmitter through the antenna or other openings and cause erratic operation or loss of control. If you
must use in wet weather during a contest, be sure to cover your transmitter with a plastic bag or waterproof barrier. Never use
if lightning is expected.
MANDATORY PROCEDURES for use with the High Response System (HRS) receivers
Use ONLY:
• Servos: Unregulated 6-Volt compatible Digital servos
• Battery: 6-Volt Unregulated NiCd or NiMH battery
• Mode: Transmitter MUST be set to HRS mode (see p. 7 and p.16 for details)
• Transmitter: Futaba’s 3PK is the first radio sold in the US with HRS capability. At this time, only the 3PK may be
used with the HRS receivers. Be sure to check any other transmitter’s operator’s manual before attempting to use with
an HRS receiver.
• NOTE: Do not attempt to operate with the Futaba FailSafe Unit (FS1) with an HRS receiver. Instead use the FailSafe
settings built into the transmitter. (see p. 17 for details.)

CARING FOR YOUR NiCd BATTERIES
Charging Your System’s Batteries
1. Connect the transmitter charging jack and receiver
NiCd batteries to the transmitter and receiver
connectors of the charger.
Charger
2. Plug the charger into a wall socket.
3. Check that the charger LED lights.
TX: Transmitter charging indicator
RX: Receiver charging indicator
To transmitter charging jack
Receiver Ni-Cd battery
The initial charge, and any charge after a complete discharge,
should be at least 18 hours to ensure full charge. The
batteries should be left on charge for about 15 hours when
recharging the standard NiCd batteries after normal use.
You should fully discharge your system’s batteries periodically to prevent a condition called memory. If you
regularly use only a small amount of the battery's capacity, the memory effect can reduce the actual capacity even if the
battery is fully charged. You can cycle your batteries with a commercial cycling unit*, or by leaving the system on and
exercising the servos by moving the transmitter sticks until the transmitter shuts itself off. Cycling should be done every
four to eight weeks, even during the winter or periods of long storage. Keep track of the batteries’ capacity during cycling;
if there is a noticeable change, you may need to replace the batteries.
*Note that your 3PK transmitter system is protected from overcharge. If the battery is charged with a quick charger for
other than digital RC systems, it may not be fully charged.
NiCd Handling Precautions
•
CAUTION - NiCd electrolyte is a strong alkali. Should you come in contact with even the smallest amount:
• EYES: DO NOT RUB, wash immediately with water, and seek medical attention at once. The electrolyte can
cause blindness.
• CLOTHING/SKIN: Wash with water immediately. Seek medical attention if rash occurs.
• DO NOT attempt to charge your 8-cell transmitter pack on the 4-cell receiver plug of the wall charger!
• NEVER plug charger into an outlet other than the standard voltage (US is 110V).
• NEVER insert or remove the charger while your hands are wet.
• ALWAYS use the provided charger or a quick charger specifically for remote control modeling. Overcharged
NiCds can result in severe burns, fire, breakage, or electrolyte leakage.
• NEVER try to recharge an alkaline dry cell battery.
• ALWAYS disconnect the radio from the charger and the charger from the wall when not in use.
• ALWAYS double-check that your batteries are fully charged prior to use.
• ALWAYS remove or disconnect the receiver NiCd when the vehicle is not in use to avoid accidental turn-ons.
• NEVER use commercially provided single NiCd battery cells. Charging these cells in your R/C system or with
R/C system chargers may result in damage to the equipment and chargers.
• NEVER drop the NiCd battery or expose it to strong shock or vibration. Crashed equipment should always be sent
for service to test for internal damage.
• NEVER leave the R/C system or batteries within the reach of small children.
• ALWAYS store the system with the batteries in a discharged state and in a cool/dry place.
• ALWAYS remove the transmitter and receiver batteries from the transmitter/vehicle for long-term storage.

APPENDIX II
Adjustments, modifications and replacements
Mechanical ATL Adjustment: Make this adjustment when you want to decrease the total travel of the brake (push) side
of the throttle trigger. For digital ATL, see p. 37.
Note: This is a mechanical stop screw only, and does not move the neutral point or affect
the acceleration (pull) side of the throttle trigger. Creating a shorter stroke allows for
more rapid response when the linkage or end point is adjusted to create the same total
servo travel.
Adjustment: Using a Phillips screwdriver, adjust the trigger brake (back) stroke by
turning the screw through the adjusting hole indicated by the arrow in the figure. (The
screw moves the throttle trigger stopper.)
•
When the adjusting screw is turned clockwise, the stroke becomes narrower. Make
this adjustment when you want to make the throttle trigger brake (back) stroke smaller
(more responsive).
CAUTION - When the stroke is adjusted, the throttle servo travel must be adjusted by linkage or programmed setting
to gain the same total movement.
Mechanical ATL
adjusting screw
Wheel Tension Adjustment: Make this adjustment when you want to change the steering
wheel spring tension.
Adjustment: Turn the screw inside the adjusting hole using a 1.5mm hex wrench.
•
Turning the adjusting screw clockwise increases the spring tension.
CAUTION - If turned too far counterclockwise, the adjusting screw may fall out.
Note: To adjust the wheel and trigger calibration, see ADJUSTER p. 45.

abnormal heating and fire may result.
53
APPENDIX III
Error Displays
Low Battery Alarm:
• If the transmitter’s battery voltage drops below 8.5V an alarm will sound and
“LOW BATTERY” will be displayed on the LCD screen.
CAUTION The low battery alarm is meant to be a safety feature only. Do NOT
operate your radio below 9V and count on the low battery warning to let you
know it is time to charge! Always shut your radio off as soon as possible after
the low battery warning tone to avoid loss of control.
• Alarm tone: continuous tone.
Backup Error:
• MEMORY “BACK UP ERROR” displays on screen if the EEPROM-stored data is
lost for any reason. The 3PK does not use a battery to store this data; it is
stored in permanent non-volatile memory. However, failures can still occur
which cause loss of this memory. If a backup error occurs, immediately stop
using the transmitter and send it for service. Do not attempt to continue to
use the radio.
• Alarm tone: 9 beeps, pause, repeat.
Model Select Error:
• EXTERNAL MODEL # “SELECT ERROR” ANY KEY > M1 SELECT displays when the
following occurs:
• Model being operated is stored in the CAMPac.
• Transmitter is turned off, and CAMPac removed.
• Transmitter is then turned back on.
The transmitter is unable to read the last model used (because it is in the CAMPac),
and so it provides a warning that it cannot select the last model memory used and
then selects model M1.
• Alarm tone: 7 beeps, pause, repeat.
CAMPac Error:
• EXTERNAL MEMORY “ACCESS ERROR” displays when a problem occurred
while copying from or to the CAMPac.
• To stop the alarm, turn off the transmitter. Turn it back on. Repeat the copy
attempt to ensure all data was safely copied.
• Alarm tone: 7 beeps, pause, repeat.
54
Memory Error:
• MAIN MEMORY “ACCESS ERROR” displays when the transmitter is turned on
and a problem occurs with accessing a model.
• To stop the alarm, turn off the transmitter. Turn it back on. If the alarm
sounds again, send for service. If it does not, the system is ready for use.
• Alarm tone: 7 beeps, pause, repeat.
Idle-Up Warning:
• IDLE UP “MIX WARNING” displays if the idle up mix is turned on when the
transmitter is turned on.
• To stop the alarm, move the idle-up switch to off.
• Alarm tone: 7 beeps, pause, repeat.

Changing Wheel Position and Modifying for Left Hand Use ........................................................................................51
Channel: The frequency number used by the transmitter to send signals to the receiver. If 2 or more radios transmit on the
same frequency, or channel, glitching will occur in the receiver, due to conflicting signals sent by the two radios. Racing
sites should have a frequency control system to ensure that only one radio operates on any given channel at one time. This
is usually a board with some type of marker for each channel. If the marker is not available, someone else is using that
channel. Do not use your radio unless you are sure you are the only one on the frequency.
Channel: The number of functions your radio can control. Ex: A 3-channel radio has 3 available servo slots used for separate
control surfaces or switches. These channels can also be mixed on many radios, for such functions as multi-servo braking.
Channel 1 > 3: In boat mode, mix from steering (rudder) to outboard. See Boat Mode. ..................................................43
Channel 3 > 1: In boat mode, mixing from outboard to steering (rudder). See Boat Mode. .............................................43

Contents and Technical Specifications................................................................................................................................5
Contrast: LCD screen contrast. See System. ......................................................................................................................13
Coreless Motor: In a conventional servo, the motor has a steel core armature wrapped in wire that spins inside the
magnets. In a coreless design, the armature uses a thin wire mesh that forms a cup that spins around the outside of the
magnet eliminating the heavy steel core. A coreless motor does not have magnets as standard servo motors do, so they have
a smoother, more constant, and stronger action. Regular servo motors have either 3 or 5 magnets (poles) which, when the
armature is between these, the servo motor is at its weakest.
Count Down Timer: See Timer ..........................................................................................................................................30
Count Up Timer: See Timer ...............................................................................................................................................30
Curve: In throttle exponential, the “curve” function offers 5 points along the range of the servo, and draws straight lines
of response between each point. It is not a true curve, as is exponential, and there are noticeable steps in the responsiveness
as each rate of response is entered. See Exponential. ..........................................................................................................20
CUT OFF: No braking action when trigger is pushed forward. Adjustment within Boat Mode. See Boat Mode............43
CYC: Adjustment in ABS. Cycle adjustment, sets how rapidly the brakes cycle from full brake applied to ABP and back
to full brake applied. See ABS. ............................................................................................................................................24
Cycle: Adjustment in ABS. One complete “pulse” of maximum brake applied to lessened brake. See ABS. ..................24
D/R2: 2nd steering dual rate. See Steering Dual Rate.........................................................................................................38
DELAY: In brake mix, waits to send command to either front or rear, allowing other to begin braking the car first. See
Brake Mix. In ABS, see DLY. ..............................................................................................................................................24
Differential. Uneven movement in each direction of a control. For example, differential steering in a 4WD car (see
programmable mixing example, p. 40.) or differential braking (see brake mix, p. 42.)
Digital Grip Dial Operation.................................................................................................................................................9

time at full brake; -3 provides maximum time at full brake (more likely to skid). See ABS. ............................................24
Dual Brake Servos: See Brake Mix....................................................................................................................................42
Dual Rate, or Primary Dual Rate: Name of the first rate setting in dual rate function. Decreases the vehicle’s steering
sensitivity across the entire range. Equivalent of decreasing brake side EPA only by that percentage. Assigned to grip dial
1 as a default to allow on-the-course adjustments. If grip dial is reassigned, dual rate may still be adjusted on-screen. Dual

FailSafe: A safety feature that moves a servo to a preset position if the signal is lost or interrupted. Please refer to
(http://www.futabarc.com/faq/product-faq.html#q102) for more information. Additionally, Battery FailSafe is a safety feature
that brings the throttle servo down to idle as a warning that the receiver battery’s voltage is getting dangerously low. ..........17
F.A.Q.: Frequently asked questions. www.futabarc.com/faq/faq-3pk.html
Field Charger: A fast battery charger designed to work from a 12-volt power source, such as a car battery. Usually takes
advantage of peak charging capability.
FM: Frequency Modulation. This describes the type of transmission of radio signal from transmitter to receiver. PPM
(commonly called simply “FM”), PCM1024, and HRS all transmit with the FM type.
Frequency Control. The FCC has allowed the 75mHz band (75.410 - 75.990) to be used for R/C ground model operations,
and the 27mHz band (26.995 - 27.255) for ground and air models. This band is divided up into many different channels on
which you can choose a radio system. You should be aware that certain areas have frequencies in which there is pager and
other interference. This is why it is always a wise move to check with your local hobby shop to find out any channels that
may be troublesome in the area. The FCC has allocated the 50mHz band (50.800 - 50.980) only to Amateur HAM license
holders for R/C use (and only at 1W maximum power output.)

See System............................................................................................................................................................................13
LAP: Current lap number. See Timer. .................................................................................................................................30
LAP-LIST:See Lap List.......................................................................................................................................................31
Lap List: Lists all stored laps for this model. Laps are stored by setting up Timer to a Lap Memory Timer, setting up a lap
start/stop in the functions screen, and then starting/running the timer while driving the vehicle. Note that lap list is NOT
reset when a model memory is reset. It must be reset manually (see instructions).............................................................31
Lap Memory Timer: Acts as a count-up timer, storing each lap and starting a new lap each time button is pressed, while
also maintaining a total run time count-up alarm, with a pre-alarm warning time. Stores up to 100 laps, visible on LAPLIST (see p. 31). Has a 3-second safety window where button press does not reset the lap. See Timer. ..........................30
LED-MODE: LED pilot lamp color. See System. ..............................................................................................................13
Lap Navigate Timer: Count-up timer which alarms at a set total run time, but also has a navigation alarm which alarms
every set interval (desired lap time), and then restarts the navigation alarm countdown on each button press or upon passing
each navigation alarm time. (Example: 4 minute track race, desired lap time is 30 seconds. Nav alarm goes off if lap counter
is not pressed before 30 seconds, then again after another 30 seconds, and so on until 4 minutes.) Great for practice-runs
and working toward a target track time. Does NOT store individual lap times. See Timer................................................30

Mandatory Procedures for using with HRS receivers ................................................................................................5, 48
Master: In programmable mixing, the channel the other servo will follow. In brake mixing, the throttle channel’s braking
side. See Programmable Mixes ............................................................................................................................................40
MC Setup (for HRS receivers only): HRS provides a very rapid frame rate – faster than most non-Futaba ESCs are
designed to read/comprehend. Therefore, most non-Futaba ESCs’ self-setup procedures are unable to complete the selfsetups and self-tests properly at this high frame rate. The MC Setup function, along with a special cord (not included),
allow the receiver to communicate with the ESC temporarily at a slower frame rate so the ESC can properly set up and be
prepared to operate properly in HRS....................................................................................................................................44

Menu Complexity: See Level Selection .............................................................................................................................12
Menu Level: See Level Selection........................................................................................................................................12
Menus: 3PK offers two separate menu types – the Direct Select menu which offers access to your 6 favorite functions with
just 2 buttons; all of the features of the radio in 3 levels of complexity (Level 1, 2, 3). ....................................................11
Metal Gears: One or more drive gears within a servo that are made of one or multiple metal types. Metal gears tend to
wear more rapidly than nylon gears when in the same installation, and so require more frequent service to maintain
optimum accuracy; however, metal gears are more durable in the case of severe vibration, flutter, or physical shock.
mHz (Megahertz = million cycles per second): The unit of radio frequency. 75 mHz are surface frequencies; 72 mHz are
air frequencies; 27 mHz and 50 mHz can be used for either ground or air applications. Note: Use of the 50 mHz (ham radio)
band requires an FCC license. The 3PK is not available on 50 mHz.
Mix Mode: Option in programmable mixing. Selects whether slave moves exactly based upon the master channel’s control
movement (unmixed) or the master channel’s servo movements after any mixing (mixed). In brake mixing, determines
whether front brakes respond based solely on trigger position (UNMIX), or whether other functions’ adjustments to rear
brakes also affect front brakes (MIXED). See Programmable Mixes. ................................................................................40
Mixing: Allows a single input to control the operation of two or more servos that are plugged into separate channels.
Simplifies more involved setups. For example, brake mixing, which utilizes 2 servos, one for front wheel braking and one
for rear wheel braking, allows different amounts of braking to front and rear when the driver simply gives brake with the
trigger. 3PK has 2 free programmable mixes which could be used to set up 4-wheel steering, separate front and rear steering
with adjustable acumen, etc. See Programmable Mixes.......................................................................................................40
MOD-MODE: Function used to select modulation for each separate model memory. ....................................................16
MODE: Setting for this function at this time – typically inhibited or active. More extensive choices are available in some functions.

Model Reset: Resets nearly all data associated with the currently-selected model memory..............................................32
Model Selection: Chooses a model memory to set up or use. ............................................................................................14
Modulation: The method or “language” used to transmit data to the receiver. 3PK supports PPM (commonly called FM),
PCM1024, and HRS. See MOD-MODE..............................................................................................................................16
62
Module: A removable/replaceable plug-in unit used in most complex computer radios, containing all frequency control
equipment, including the crystal and all tuned components. Changing channels or bands on a modular radio requires only
changing module. Changing crystals WITHIN a module to change the channel of the module itself is against FCC
regulation and is not recommended. To use your transmitter on a different channel you simply purchase another module
on that other channel and the radio is now properly tuned and safe and easy to use on that other channel as well. The 3PK
uses a new, specialized module, the PK, which can transmit not only in PPM and PCM but also HRS..............................7
MXMD: Mix mode. See mix mode, Programmable Mixes ................................................................................................40
Narrow-Band: A radio with a 20 KHz band width. All Futaba radios produced 1992 or later and all Futaba FM, HRS and
PCM radios ever produced are narrow band.

receivers. See Caring for your NiCd Batteries....................................................................................................................49
Nitro (Nitromethane): A fuel additive that increases a model engine’s ability to idle low and improves high speed
performance. Ideal nitro content varies from engine to engine. Refer to the engine manufacturer’s instructions for best
results. Nitro content in fuel is indicated by what percent of the fuel volume is nitro.
No.: Number. In timer, number of laps stored and ready to display. See Timer. ................................................................30
NVALM: Number of times the navigation alarm went off, indicating you exceeded your desired run time. See Timer. ........30
Nylon gears: Drive gears within a servo made of nylon. Nylon gears show slower wear than metal gears, but are more
prone to failure due to severe vibration or physical shock to the servo.
Offset: Option in programmable mixing. Amount off center to adjust the mix. See Programmable Mixes......................40
PCM (Pulse Code Modulation): PCM systems use digitally encoded signals to minimize interference and provide today’s
most advanced R/C control. See MOD-MODE. ..................................................................................................................16
Peak Charger: This type of charger will eliminate the guesswork. When the battery is fully charged (peaked), the charger
reverts to a maintenance charge rate, which will not damage the pack.
Peak: This is the point at which a battery will no longer accept a charge, and converts the energy to heat. This is damaging
to the battery pack, and potentially hazardous.
