For Your Safety As Well As That Of Others
Do not operate outdoors on rainy days, run through puddles of water or use when visibility is lim-
ited.
Should any type of moisture (water or snow) enter any component of the system, erratic operation and loss of control may occur.
Do not operate in the following places.
-Near other sites where other radio control activity may occur.
-Near people or roads.
-On any pond when passenger boats are present.
-Near high tension power lines or communication broadcasting antennas.
Interference could cause loss of control. Improper installation of your Radio Control System in your model could result in serious injury.
Operation Precautions
Do not operate this R/C system when you are tired, not feeling well or under the influence of alco-
hol or drugs.
Your judgment is impaired and could result in a dangerous situation that may cause serious injury to yourself as well as others.
Do not touch the engine, motor, speed control or any part of the model that will generate heat while
the model is operating or immediately after its use.
These parts may be very hot and can cause serious burns.
Always perform an operating range check prior to use.
Problems with the radio control system as well as improper installation in a model could cause loss of control.
(Simple range test method)
Have a friend hold the model, or clamp it down or place it where the wheels or prop cannot come in contact with any ob-
ject. Walk away and check to see if the servos follow the movement of the controls on the transmitter. Should you notice
any abnormal operation, do not operate the model. Also check to be sure the model memory matches the model in use.
Turning on the power switches.
Always check the throttle trigger on the transmitter to be sure it is at the neutral position.
1. Turn on the transmitter power switch.
2. Turn on the receiver or speed control power switch.
Turning off the power switches
Always be sure the engine is not running or the motor is stopped.
1. Turn off the receiver or speed control power switch.
2. Then turn off the transmitter power switch.
If the power switches are turned off in the opposite order, the model may unexpectedly run out of control and cause a very
dangerous situation.
When making adjustments to the model, do so with the engine not running or the motor discon-
nected.
You may unexpectedly lose control and create a dangerous situation.
(Fail safe function)
Before running (cruising), check the fail safe function.
Check Method; Before starting the engine, check the fail safe function as follows:
1) Turn on the transmitter and receiver power switches.
2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail safe
data to the receiver every minute.)
3) Check if the fail safe function moves the servos to the preset position when reception fails.
The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when recep-
tion fails. However, if set to a dangerous position, it has the opposite effect. When the reverse function was used to change
the operating direction of a servo, the fail safe function must be reset. Setting example: Throttle idle or brake position

(Only when Ni-MH/Li-ion batteries are used)
Battery Handling Precautions
Never plug the charger into an outlet of other than the indicated voltage.
Plugging the charger into the wrong outlet could result in an explosion or fire.
Never insert or remove the charger while your hands are wet.
You may get an electric shock.
Do not use the transmitter's battery, HT5F1700B or FT2F1700BV2 as the receiver's battery.
Since the transmitter's battery has an overload protection circuit, the output power will be shut down when the high current
load is applied. This may result in runaway or fatal crash.
Do not use commercial AA size Ni-MH and Li-ion batteries.
Quick charging may cause the battery contacts to overheat and damage the battery holder.
Do not short circuit the battery terminals.
A short circuit across the battery terminals may cause abnormal heating, fire and burns.
Do not drop the battery or expose it to strong shocks or vibrations.
The battery may short circuit and overheat; electrolyte may leak out and cause burns or chemical damage.
When the model is not being used, always remove or disconnect the battery.
Leaving the battery connected could create a dangerous situation if someone accidentally turns on the receiver power
switch. Loss of control could occur.
Always check to be sure your batteries have been charged prior to operating the model.
Should the battery go dead while the model is operating, loss of control will occur and create a very dangerous situation.
To recharge the transmitter battery, use the special charger made for this purpose.
Overcharging could cause the battery to overheat, leak or explode. This may lead to fire, burns, loss of sight and many
other types of injuries.
Always keep the charger disconnected from the outlet while it is not in use.
Do this to prevent accidents and to avoid overheating.
When running (cruising), do not use the dry cell battery box at the transmitter.
The accessory dry cell battery box is for performance checks. Do not use it for other than performance checks. The dry cell
battery may be separated from the battery box contacts by shock and the power cut off. If the power is cut off while running
(cruising), a collision may occur. The use of Futaba a genuine NiMH or LiFe battery pack is strongly recommended.
Do not connect the charger when the battery is not connected.
A load will be applied to the circuit and the transmitter may be damaged.

Storage and Disposal Precautions
Do not leave the radio system or models within the reach of small children.
A small child may accidentally operate the system. This could cause a dangerous situation and injuries. Ni-Cd batteries
can be very dangerous when mishandled and cause chemical damage.
Do not throw Ni-MH/LiFe batteries into a fire. Do not expose batteries to extreme heat. Also do
not disassemble or modify a battery pack.
Overheating and breakage will cause the electrolyte to leak from the cells and cause skin burns, loss of sight, and other
injuries.
When the system will not be used for any length of time, store the system with HT5F1700B batteries
in a discharged state. Be sure to recharge the batteries prior to the next time the system is used.
If the batteries are repeatedly recharged in a slightly discharged state, the memory effect of the Ni-Cd battery may con-
siderably reduce the capacity. A reduction in operating time will occur even when the batteries are charged for the recom-
mended time. (After discharge to 1cell E.V.=1V)
<Battery Electrolyte>
The electrolyte in Ni-MH/Ni-Cd batteries is a strong alkali. Should you get even the smallest amount of the electrolyte in your
eyes, DO NOT RUB. Wash immediately with water, and seek medical attention at once. The electrolyte can cause blindness.
If electrolyte comes in contact with your skin or clothes, wash with water immediately.
Do not store your R/C system in the following places.
- Where it is extremely hot or cold.
- Where the system will be exposed to direct sunlight.
- Where the humidity is high.
- Where vibration is prevalent.
- Where dust is prevalent.
- Where the system would be exposed to steam and condensation.
Storing your R/C system under adverse conditions could cause deforma-
tion and numerous problems with operation.
If the system will not be used
for a long period of time, re-
move the batteries from the
transmitter and model and
store in a cool, dry place.
If the batteries are left in the transmit-
ter, electrolyte may leak and damage
the transmitter. This applies to the
model also. Remove the batteries
from it also to prevent damage.
Do not expose plastic parts to fuel, motor spray, waste oil or exhaust.
The fuel, motor spray, waste oil and exhaust will penetrate and damage the plastic.
Always use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed con-
trols), Ni-MH/Ni-Cd/Li-ion batteries and other optional accessories.
Futaba will not be responsible for problems caused by the use of other than Futaba genuine parts. Use the parts speci-
fied in the instruction manual and catalog.
Other Precautions
<Battery Recycling>
A used battery is a valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center.

Before Using
-Response change function
The operation response can be set in 50 steps to match your preference and the course and ve-
hicle.
-Anti-skid braking system (A.B.S.)
This function applies the brakes so that the tires of gasoline engine cars, etc. do not lose their
grip on the road even when braking at corners.
-Throttle acceleration
Gasoline engine cars have a time lag before the clutch and brakes become effective.
The TH-ACCEL function reduces this time lag.
-Throttle speed
Sudden trigger operation on a slippery road surface will only cause the tires to spin and the
model to not accelerate smoothly. By setting the throttle speed function, operation can be per-
formed smoothly and easily. It also suppresses battery consumption.
-Steering speed
When you sense that the steering servo is too fast, etc., the servo operating speed (direction that
suppresses the maximum speed) can be adjusted.
-Non-telematry LED

Matched to the ratings of the receiver and connected digital servo.
The set cannot operate in the "Digital servo" type. Operation in this type will cause trouble with the servos and other equip-
ment. Digital servos (including BLS Series brushless servos) can also be used in the "Analog servo" type.
Always use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed controls),
Ni-MH/Ni-Cd/Li-ion batteries and other optional accessories.
Futaba will not be responsible for problems caused by the use of other than Futaba genuine parts. Use the parts specified
in the instruction manual and catalog.

Before Using
Power & Display Switch
The power switch and display switch are push switches.
When the power switch (PWR) is held down, operation starts by transmitting radio waves. When
the display switch is held down, the transmitter side data can be checked and set. When the power
is turned off, if the power switch or display switch is held down, the power is turned off. If both
switches are pressed simultaneously, the power is turned off quickly.
Power Off Forgotten Alarm & Auto Power Off
At T4PX initialization, if steering wheel, throttle trigger, push switch, edit button, or other
operation is not performed within 10 minutes, an audible alarm will sound and the message
"Warning: Auto power off" will appear.
If steering wheel, throttle trigger, push switch, edit button or other
operation is performed, the alarm is reset. Also turn off the power
when the transmitter is not in use. If the alarm is not reset, the auto
power off function will automatically turn off the power after 5
minutes. If you do not want to use this alarm and the auto power off
function, they can be disabled by system setting (p.148).
Low Battery Alarm
If the transmitter battery voltage drops below the usable range, an audible alarm will sound
and "Low battery" will be displayed. Since the usable range of LiFe and NiMH batteries and
LiFe batteries is different, the power supply used must be set by system setting. If the battery
goes dead while running (cruising), since there is the danger of collision, immediately recover
the vehicle (boat) and stop running (cruising).
Warning
When a low battery alarm is generated, cease operation immedi-
ately and retrieve the model.
If the battery goes dead while in operation, you will lose control of the model.

Connector Connections
Servo Installation
Be sure the receiver, servo, battery and connectors are fully and firmly connected.
If vibration from the model causes a connector to work loose while the model is in operation, you may lose control .
When you install the servos, always use the rubber grommets provided in servo hardware bags. Mount the
servos so they do not directly come in contact with the mount.
If the servo case comes in direct contact with the mount, vibration will be directly transmitted to the servo.
If this condition continues for a long time, the servo may be damaged and control will be lost.
Servo Throw
Operate each servo over its full stroke and be sure the linkage does not bind or is loose.
The continuous application of unreasonable force to a servo may cause damage and excessive battery drain.

Electronic Speed Cont
Motor Noise Suppression
Install the heat sinks where they will not come in contact with aluminum, carbon fiber or other parts that conduct
electricity.
If the FET Amp (Electronic speed control) heat sinks touch other materials that conduct electricity a short circuit could oc-
cur. This could result in loss of control and damage to the system.
Always install capacitors to suppress noise when electric motors are used.
If capacitors are not properly installed you could experience erratic operation and reduced range as well as loss of control.
Other Noise Suppression Methods
Be sure there are no metal parts in your model which under vibration can come in contact with other metal parts.
Metal to metal contacts under vibration will emit a high frequency noise that will affect the receiver's performance. You
could experience erratic operation and reduced range as well as loss of control.

Initial Set-Up
Before setting up each function of the transmitter, check and set the following items.
RF Output & Rx Type Check
Check if the receiver type is set to the type of receiver used.
*When the "PWR" side power switch is set to ON and radio
waves are output normally, "T-FHSS", "S-FHSS", or "FASST" is
displayed. If not displayed, there is probably an abnormality or
trouble so contact a Futaba Service Center.
When a screen is displayed at the "DSP" side, "Display" is dis-
played.
*Since the R304SB receiver supplied with the T4PX set uses the
telemetry function T-FHSS system, T4PX receiver setup must be
set to T-FHSS.
The R2104GF and other S-FHSS and FASST system receivers, as well as the R304SB T-
FHSS system receiver can be used with the T4PX transmitter. However, only R614FS/FS/
FF-E and R604FS/FS-E "C2" type receivers can be used with the FASST system.
The R603FS/FF "C1" type cannot be used.

3Bring the transmitter and receiver within 50cm of each other (antennas do not touch) and
turn on the receiver power.
4Move the cursor to "Link" by T4PX transmitter (JOG) button up or down operation. When
the (JOG) button is pressed, a chime will sound and the T4PX will enter the link mode for
20 seconds. During this 20 seconds link mode, press the receiver tactile switch for at least 2
seconds.
5During the 20 seconds link mode, press the receiver tactile switch for at least 2 seconds.
The LED blinks red and then changes to a greenish red green steady light. When the
T4PX makes a beeping sound and the message "Link with receiver" appears on the screen,
release the receiver tactile switch. This ends reading of mutual ID and displays the memo-
rized receiver ID number on the T4PX screen. If the "Receiver not found" error screen is dis-
played, linking failed. Check the set contents and repeat the linking operation.
*The T4PX and a telemetry system T-FHSS receiver (R304SB, etc.) memorize the IDs linked
last at each model memory. Since only one receiver ID is memorized at each model mem-
ory, multiple T-FHSS receivers cannot be used with the same model memory. When a re-
ceiver at the same model memory is changed, re-linking is necessary even if the receiver is
already linked with the transmitter.
When using multiple T-FHSS telemetry receivers, link each receiver with each T4PX model
memory. However, one receiver can be linked with multiple model memories. The telemetry
function communication status can be checked at the T4PX home screen.

Receivers Other Than T-FHSS
1Bring the transmitter and the receiver close to each other,
within 20 inches (half meter).
2Turn on the transmitter.
3Turn on the receiver.
4Push the tactile switch of the receiver.
When the link is complete, the LED in the receiver changes
to solid green.
Precaution:
If there are many Futaba 2.4GHz systems (T-FHSS/ S-FHSS/ FHSS) turned on in close proximity to your receiver
might not link to your transmitter. In this case, even if the receiver’s LED stays solid green, unfortunately the receiv-
er might have established a link to one of other transmitters. This is very dangerous if you do not notice this situa-
tion. In order to avoid the problem, we strongly recommend you to double-check whether your receiver is really un-
der control by your transmitter by giving the stick input and then checking the servo response.
*Please refer to the table below for LED status vs receiver's condition.
LED status vs receiver’s condition:
Warning
After the linking is done, please cycle receiver power and check if the receiver to be linked is really under the
control of your transmitter.
Do not perform the linking procedure with motor’s main wire connected or the engine operating as it may result in
serious injury.

Initial Set-Up
Servo Type Check
Check if the servo type setting matches the servo used. When
a digital servo (including BLS brushless servo) is used, "Digi-
tal servo" or "Analog servo"" can be set. Since an analog servo
cannot be used with the "Digital servo" setting, the servo type
must be set to "Analog servo". If used with the wrong setting,
the analog servo will be damaged. If the setting is incorrect,
change it by the following method.

Initial Set-Up
- Steering dual rate (DT5) check
At initial set-up, steering dual rate (D/R) is assigned to DT5 trim lever, at the grip of the
transmitter. Operate the DT5 and check if the D/R value displayed on the screen changes.
After checking D/R, set the steering dual rate to 100%.
- Brake rate (DT6) check
At initial setting, brake rate (Brake1 rate) is assigned to DT6 trim lever, below DT6. Operate
the DT6 and check if the Brake1 rate value displayed on the screen changes. After checking
Brake1 rate, set brake rate to 100%.
(Set-Up Procedure When Installed In a Car)
When installing the servos in a car, performing function set-up in the following order is
recommended.
1 Initialize all the trims.
2Set the servo direction of operation using the Reverse function. (p.47)
- The servo installation method and linkage direction depend on the kit. Therefore, the servo
operation direction may have to be reversed relative to transmitter operation. Before install-
ing the servo, check the operating direction and set it using the Reverse function.
3Set the subtrim and adjust the servo neutral point. (p.48)
4Set the trigger travel by adjusting the throttle trigger mechanical ATL to
your liking. (p.18)
- When the stroke was adjusted, compensate the throttle by adjuster function (p.152).
5
Set EPA of each channel and adjust the servo throw (travel). (

R304SB T-FHSS system receiver supplied. However, only the "C2" type (R614FS/FF/FF-
E,etc) receivers can be used with the FASST system. The R603FS/FF "C1" type receiver
does not operate. Make your selection by matching to the system of the receiver to be used.
The model data remains unchanged even if the receiver setting is changed.
"
Digital servo type" or "Analog servo type" servo type can be selected. However, the
"Digital servo type" is for Futaba digital servos (including BLS Series brushless servos)
use only. When using other servos, select the "Analog servo type". All servos, including

Function
End Point
End Point Adjuster (All channel)
Use this when performing left and right end point adjustments, throttle high side/brake
side operation amount adjustment, channel 3 and channel 4 servo up side/down side op-
eration amount adjustment during linkage.
- Correct the maximum steering angle for left and right steering angles when there is a
difference in the turning radius due to the characteristics, etc. of the vehicle.
The End point function basically determines the maximum steering angle of each chan-
nel.
The functions shown below may have been adjusted or the operating range set by End
point function may be exceeded. Check the linkage each time the following functions
are adjusted.
- Sub trim (all channels)
- Program mixing slave side (all channels)
- Tilt mixing (steering, channel 3)
- Idle up (throttle)
- Start Function, Engine Cut (throttle)
- Throttle acceration (throttle)
Maximum steering angle
Brake rate trim allows adjustment of the brake side operation amount during operation.
Therefore, when the operating angle is adjusted with throttle End point, Brake rate trim
must also be taken into account.

(140%), the steering angle can be increased somewhat by using program mixing.
(Setup example: See page 96.)
Remark
Warning
Operate each servo over its full stroke and be sure
the linkage does not bind or is not loose.
The continuous application of unreasonable force to a servo may
cause damage and excessive battery drain.
Adjust the throttle servo so that unreasonable force is not applied when the engine carburetor is fully
open, fully closed, and the brakes are applied fully.
If the brakes overheat while running, their ability to function properly decreases. Before running, adjust
the suitable maximum servo travel so that unreasonable force is not applied even when the servo travel
is increased while running.
Adjust the steering servo so that unreason-
able force is not applied to the servo by the
chassis at maximum servo travel.
Decide the End point
value at the contact
point.
Caution!
A whining noise indicates that the
steering servo is improperly set.
