INT1 AND INT2 MENU {INTERVAL 1 AND INTERVAL 2 TIMERS}SETUP
The Interval Timer function is used to notify you when a set Interval elapses while you're driving. When the Interval Time is
reached, an audible Double-Tone will sound, then the Interval Timer will Reset and begin counting Up again from zero. Interval
Times are displayed in the following format: 00':00".00 (Minutes : Seconds : 1/100th of a Second). The Interval Timer can be
programmed to work independently or programmed to work along with the Lap Timer function.
This section covers both the INT1 and INT2 menus, since programming each of them is exactly the same. Choose either the
INT1 or the INT2 menu depending on which of the two Interval Timers you want to program.
There are two Interval Timers. These Interval Timers can be Started and
Stopped independently by Assigning each one to a different Push-Button
Switch or they can be Started and Stopped simultaneously by Assigning
both of them to the same Push-Button Switch. If desired, different Tones can
be Assigned to each Interval Timer to differentiate them and the Throttle
Trigger can be programmed to Start the Interval Timer(s).
In the default configuration, Interval Timer 1 is Started and Stopped along
with the Lap Timer, using the Lap Timer Switch (Push-Button Switch Sw3).
Setting the Interval Timer:
1) From within the SETUP menu, scroll UP or DOWN to highlight either the INT1
or the INT2 menu depending on which Interval Timer you want to program. In
this section, we show programming Interval Timer 1.
2) Press the ENTER key to open the INT1 menu. INTERVAL > 00' will be highlighted.
3) Scroll UP or DOWN to highlight the desired Interval Timer value you would like
to change, either 00' (Minutes) , 00" (Seconds) or 00 (1/100th Seconds).
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Interval
Timer value.
5) Press the ENTER key again, then repeat steps 3 and 4 to change any other
desired Interval Timer values.

Starting the Interval Timers:
In the default configuration, the Lap Timer Switch (Push-Button Switch Sw3) controls both the Lap Timer and Interval Timer 1.
To control Interval Timer 2, it must first be Assigned to a Push-Button Switch. If desired, the Interval Timers can be Started and
Stopped independently by Assigning each one to a different Push-Button Switch or they can be Started and Stopped simultaneously
by Assigning both of them to the same Push-Button Switch. Regardless of what you decide, follow the step below to control the
Interval Timer(s).
1) Press and HOLD the Push-Button Switch you've Assigned the Interval Timer(s) to for 3 seconds. An audible Double-Tone will
sound and INT1 [STANDBY] or INT2 [STANDBY] will be displayed momentarily in a pop-up window, indicating the Interval
Timer is in Standby. To Start the Interval Timer, press the Push-Button Switch a second time or pull the Throttle Trigger if you've
Enabled the Start Trigger function. An audible Double-Tone will sound and the Interval Timer will start counting Up. Each time
the Interval Time elapses, an audible Double-Tone will sound and the Interval Timer will Reset and start counting Up again
from zero. If desired, you can manually Restart the Interval Timer from zero by pressing the Push-Button Switch while the
Interval Timer is running.
If the Interval Timer is Assigned to the same Push-Button Switch as the Lap Timer and the Lap Timer is Assigned to
Function 1, LAP will flash and Lap Time information will be displayed in a pop-up window, but the Interval Timer will run in
the background.
When both Interval Timers are Assigned to the same Push-Button Switch, only the Interval Timer Assigned to Function 1
will be displayed in the pop-up window when the Interval Timers Start and Stop, however, if the Interval Timers are set to
different values, each Interval Timer will be displayed in the pop-up window as the Interval Times are reached.
Stopping the Interval Timers:
1) To stop the Interval Timer(s), press and HOLD the Push-Button Switch you've Assigned the Interval Timer(s) for 3 seconds. An
audible Double-Tone will sound indicating the Interval Timer(s) is stopped.
When Stopped, the Interval Timer will read 00'01"00. This is normal. This value will be cleared when the Interval Timer is
placed in Standby again.

RACING MENU OVERVIEW RACING
R-MODE MENU {RACING MODE}RACING
The Racing Mode function provides you with five separate Racing Modes that you can switch between while you're driving. For
example, due to changing track conditions or other variables, such as tire wear, different Racing Modes can be Selected at any time
to change your Model's setup. A number of functions, such as Dual Rate, Exponential, Curves, Compensation Mixing and more,
that might commonly be required to be changed during the course of a race can be programmed with different Programming Values
for each Racing Mode. This ensures that your Model can operate with the best-suited setup for ever-changing track conditions
throughout an entire race, giving you an advantage over other drivers.
Functions can be programmed the same for all five Racing Modes or functions can be programmed independently, allowing you
to have different function Programming Values for each of the five Racing Modes and switch between them while driving.

R-MODE MENU {RACING MODE}RACING
Turning Separate Functions ON and OFF:
When Racing Mode is turned ON (R-MODE > ACT), various functions can be programmed the same for all five Racing Modes or
they can be programmed independently, allowing you to have different function Programming Values for each of the five Racing
Modes. For example, with D/RST set to ON, you can choose a Dual Rate Steering percentage value of 100% for Racing Mode 1, a
Dual Rate Steering percentage value of 90% for Racing Mode 2 and so on.
1) From within the R-MODE menu, scroll UP or DOWN to highlight desired
function you would like to turn ON or OFF.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired value,
either ON or OFF. When set to ON, you will be able to choose different
function Programming Values for each Racing Mode. When set to OFF,
function Programming Values will be the same for all Racing Modes.
SEPARATE functions setting range is OFF and ON. The default setting for all functions is OFF.
3) Press the ENTER key, then repeat steps 1 and 2 to change any other desired values.
Switching Racing Modes to Program Separate Functions:
If you've chosen to program one or more Racing Mode functions separately (as
described above), a Racing Mode Icon will be displayed within the specific
function Programming Menu to indicate which Racing Mode you're currently
programming the function for.
To program different values for each Racing Mode, make sure to switch to the desired Racing Mode first. For example, with
SEPARATE D/RST set to ON, open the D/R menu. An R1, R2, R3, R4 or R5 Racing Mode Icon will be displayed next to the Steering
function, depending on which current Racing Mode is Active.
Use the Racing Mode Switch (Trim Switch Trm4) to switch to Racing Mode 1. R1 will be displayed next to the ST > 100%
percentage value. Choose the desired Steering Dual Rate percentage value for Racing Mode 1, then press Trim Switch Trm4 to
switch to Racing Mode 2. R2 will be displayed next to the ST > 100% percentage value. Choose the desired Steering Dual Rate
percentage value for Racing Mode 2. While you're driving, you can now switch to different Dual Rate settings simply by switching
Racing Modes.
The Racing Mode Icon will only be displayed for Programming Menus within the RACING menu and only if the specific
function's Separate value is set to ON in the R-MODE menu. If no Racing Mode Icon is displayed, the function Programming
Value will be the same regardless of which Racing Mode is currently Active.
D /R MENU {DUAL RATES}RACING
The Dual Rate function allows you to change the control authority of the Steering, Throttle High Side and Throttle Brake Side by
changing the amount of servo travel relative to control input. For example, by Increasing the Steering Dual Rate, you can make
the Steering servo travel more which might prevent your Model from pushing during turns. If your Model oversteers during turns,
you can reduce the amount of Steering Dual Rate.
IMPORTANT: Prior to programming the Dual Rate function, you should adjust the maximum Left and Right (or High and Low)
End Points. For more information, see the
EPA Menu
section on page 62.
In the default configuration, Trim Switch Trm3 controls Steering Dual Rate and
Trim Switch Trm5 controls Brake Dual Rate. Throttle Dual Rate can be changed
while you're driving by Assigning the Dual Rate function to another Trim Switch
or the Auxiliary Dial. For more information, see the
ASSIGN Menu
section on
pages 33 ~ 38.
Current Steering, Throttle and Brake Dual
Rate percentage values are displayed in the
Lower Right corner of the STATUS screen.

Changing the Dual Rate Percentage Values:
1) From within the RACING menu, scroll UP or DOWN to highlight the D/R menu.
3) Scroll UP or DOWN to highlight the desired Dual Rate percentage value you
would like to change.
4) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
Dual Rate percentage value. Increasing the percentage value will Increase
servo travel and Decreasing the percentage value will Decrease servo travel.
5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired
Dual Rate percentage values.
DUAL RATE setting range is 0% to 100%. The default setting for all channels is 100%.
2) Press the ENTER key to open the D/R menu. ST > 100% will be highlighted.
Dual Rate is a percentage of End Point Adjustment. For example, if you set the Steering Dual Rate percentage value to 100%,
the Steering will travel the same amount defined by your End Point Adjustment programming. Alternately, if you set the Steering
Dual Rate percentage value to 50%, the Steering will travel half the amount defined by your End Point Adjustment programming.
D /R MENU {DUAL RATES}RACING
TRIM MENU {SERVO TRIM}RACING
The Trim function allows you to view the current Trim value for each of the four channels and, if desired, allows you to change the
Trim values using the Push-Button Rotary Dial from within the TRIM menu. For example, if you don't Assign Auxiliary 1 Trim to a
Trim Switch, you can still Trim the Auxiliary 1 channel from within the TRIM menu.
The M12S features Digital Trim Memory. Any amount of Trim that you set during use using the Trim Switches or through the TRIM
menu is automatically stored in memory for that specific channel and for that specific Model. The Trim values for each Model will
automatically be loaded when the transmitter is turned ON.
Each time you move a Trim Switch a short audible Tone is heard. When the Trim value reaches 0 (Centered), a longer audible
Tone sounds. This indicates to you that the Trim is centered without the need to look at the transmitter.
In the default configuration, Trim Switch Trm1 and Trm2 move the Steering and Throttle/Brake Trim in 5% increments. If
you want to Increase or Decrease the Trim Resolution, see the
Changing the Trim Switch Step Value
section on page 35.
In the default configuration, Trim Switch Trm1 controls Steering Trim and
Trim Switch Trm2 controls Throttle/Brake Trim. Auxiliary channel Trim can be
changed while you're driving by Assigning the Trim function to another Trim
Switch or the Auxiliary Dial. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
The current Trim positions for all four channels is
shown on the Trim Displays on the STATUS screen.
PRO TIP: The Trim function features two different Trim Type options that you can choose from. Choose from either Center Trim
or Parallel Trim. For more information, see the
TRIM TYPE Menu
section on page 43.

TRIM setting range is 0 to 100 in each direction. The default setting for all channels is 0.
Before changing the Trim values, you should first verify that all Trim values are set to 0, then adjust the servo Sub-Trim
values to center the servo horns perfectly. For more information, see the
SUB TRIM Menu
section on page 63.
CURVE MENU {EXPONENTIAL, ADJUSTABLE RATE CONTROL AND CURVE}RACING
The CURVE menu allows you choose what method you would like to use to vary the amount of servo travel in relation to the
amount of control movement. Choose from Exponential, Adjustable Rate Control (ARC) and Point Curve functions. Each of
these three functions offers something different, and which function you choose to use for each channel will be determined by
many factors, including your Car Type, track conditions, driving style and more.
Exponential, Adjustable Rate Control and Point Curve functions can be programmed for each of the four channels.
Programming options will differ within each function depending on the specific channel you're programming. For example,
if your Car Type features Front and Rear Steering and Front and Rear Motors (such as Car Type X), only ST and TH channel
options will be programmable, however, both Front and Rear channels will be programmed with the same Programming Values.
Exponential Programming
The Exponential function allows you to vary the amount of servo travel in relation to the movement of the Steering Wheel and
Throttle Trigger (or in some cases, the Auxiliary Dial and/or the Auxiliary Lever) near the Neutral positions to change the way those
functions react to control movement.
Decreasing the Exponential Rate percentage value will Soften the control feel around Neutral and Increasing the Exponential
Rate percentage value will Heighten the control feel around Neutral. Using a Lower Negative value allows for smoother control.
Using a Higher Positive value may result in more 'twitchy' control response.

Exponential Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the
Auxiliary Dial or the Auxiliary Lever. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
Exponential Rate percentage values can be adjusted from Mild through Linear to
Quick to allow you to set the most effective control response for your Model. For
example, if your Model over-steers, reduce the Steering Exponential Rate percentage
value and if your Model under-steers, Increase the Steering Exponential Rate
percentage value.
For another example, reduce the Throttle High Side Exponential Rate percentage
value on a slippery track or with a Model that has a Higher-torque motor or engine,
and Increase the Throttle High Side Exponential Rate percentage value on a
high-grip track or with a Model that has a Lower-torque motor or engine.
For the utmost in precision control, Exponential Rate percentage values can be
adjusted separately for the Throttle High Side and the Throttle Brake Side. In addition,
the Exponential Tweak Right and Tweak Left function allows you to balance
Exponential for Right and Left Steering.

4) From within the CURVE menu, scroll UP or DOWN to highlight the TYPE > value.
5) Press the ENTER key and scroll UP or DOWN to choose TYPE > EXP.
Changing the Rate Percentage Value:
The Rate percentage value determines the amount and type of Exponential, either Quick, Mild or Linear (see diagram on the
previous page). When a Positive or Negative Exponential percentage value is programmed, a Curve will be created from a fixed
Neutral Point. This Curve will be equal on both sides, except for the Throttle channel. For more information, see the notation below.
1) From within the CURVE menu, scroll UP or DOWN to highlight RATE > 0%.
2) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
Rate percentage value. Using a Negative Rate percentage value will Soften
the control feel around Neutral and using a Positive Rate percentage value
will Heighten the control feel around Neutral.
RATE setting range is -100% (Mild) to 100% (Quick). The default setting is 0% (Linear).
You are able to adjust the Rate percentage value for the Throttle High Side
and the Throttle Brake Side separately. In addition, you can even program
Exponential for one Side and ARC or Point Curve for the other Side.
Changing the Steering Tweak Right and Tweak Left Values:
The Tweak function allows you to make small Exponential adjustments to the Right and/or Left sides of the Steering channel Neutral
Point to fine-tune the balance between the two sides. Tweak value adjustments are effective whether you program a Negative or
a Positive Rate value, or even program a Linear Rate value (0).
1) From within the CURVE menu, scroll UP or DOWN to highlight the desired
Tweak value, either TWEAK L or TWEAK R.
2) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
Tweak value. Using a Negative Tweak value will Soften the control feel that
side of Neutral and using a Positive Rate percentage value will Heighten the
control feel around that side of Neutral.
3) Press the ENTER key, then repeat steps 1 and 2 to change the other Tweak value, if desired.
TWEAK L and TWEAK R setting range is -20 (Mild) to 20 (Quick). The default setting for both Tweak values is 0 (Linear).

CURVE MENU {EXPONENTIAL, ADJUSTABLE RATE CONTROL AND CURVE}RACING
Adjustable Rate Control Programming
The Adjustable Rate Control (ARC) function allows you to vary the amount of servo travel in relation to the movement of the
Steering Wheel and Throttle Trigger (or in some cases, the Auxiliary Dial and/or the Auxiliary Lever) near the Neutral positions to
change the way those functions react to control movement.
Decreasing the ARC Rate percentage value will Soften the control feel around Neutral and Increasing the ARC Rate percentage
value will Heighten the control feel around Neutral. Using a Lower Negative value allows for smoother control. Using a Higher
Positive value may result in more 'twitchy' control response.
The Adjustable Rate Control function works like the Exponential function, except that the Adjustable Rate Control function features
the added benefit of being able to move the Neutral Point, whereas the Exponential function Neutral Point is fixed. In addition, the
ARC Curve is more Linear than the Exponential Curve.
Adjustable Rate Control Programming Values can be changed while you're driving by Assigning these functions to a Trim
Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
ARC Rate percentage values can be adjusted from Mild through Linear to Quick to
allow you to set the most effective control response for your Model. For example, if
your Model over-steers, reduce the Steering ARC Rate percentage value and if your
Model under-steers, Increase the Steering ARC Rate percentage value.
For another example, reduce the Throttle High Side ARC Rate percentage value on
a slippery track or with a Model that has a Higher-torque motor or engine, and
Increase the Throttle High Side ARC Rate percentage value on a high-grip track or
with a Model that has a Lower-torque motor or engine.
For the utmost in precision control, ARC Point and Rate values can be adjusted
separately for the Throttle High Side and the Throttle Brake Side. A graph that
depicts the control output and ARC Curve relationship is featured to help visualize

You are able to adjust the Point value and the Rate percentage value for
the Throttle High Side and the Throttle Brake Side separately. In addition,
you can even program ARC for one Side and Exponential or Point Curve for the
other Side.
Changing the Rate Percentage Value:
The Rate percentage value determines the amount and type of ARC, either Quick, Mild or Linear (see diagram on the previous
page). When a Positive or Negative ARC percentage value is programmed, a Linear Curve will be created from the Neutral Point.
1) From within the CURVE menu, scroll UP or DOWN to highlight RATE > 0%.
2) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
Rate percentage value. Using a Negative Rate percentage value will Soften
the control feel around the Neutral Point and using a Positive Rate percentage
value will Heighten the control feel around the Neutral Point.
RATE setting range is -100% (Mild) to 100% (Quick). The default setting is 0% (Linear).
Point Curve Programming
The Point Curve function allows you to vary the amount of servo travel in relation to the movement of the Steering Wheel and
Throttle Trigger (or in some cases, the Auxiliary Dial and/or the Auxiliary Lever) at different Points along the entire range of
control travel to change the way those functions react to control movement. Nine programmable Points allow you to create your
own custom Point Curve to suit any situation.
The Point Curve function works like the Exponential and ARC functions, except that the Point Curve function allows you to
program up to 9 different Points along the entire range of control travel to suit whatever setup or situation is required. For example,
you can customize the Point Curve to include Mild or Quick Points along the same Curve, or you can create a smooth Point Curve
or a more Linear Point Curve.
Point Curve percentage values can be adjusted from Mild through Linear to Quick
to allow you to set the most effective control response for your Model. For example,
if your Model over-steers, reduce the Point Curve percentage values and if your
Model under-steers, Increase the Point Curve percentage values.
For another example, reduce the Throttle High Side Point Curve percentage values
on a slippery track or with a Model that has a Higher-torque motor or engine, and
Increase the Throttle High Side Point Curve percentage values on a high-grip track
or with a Model that has a Lower-torque motor or engine.
For the utmost in precision control, Channel Curves can be programmed separately
for the Throttle High Side and the Throttle Brake Side. A graph that depicts the

SPEED MENU {SERVO SPEED}RACING
The Servo Speed function allows you to slow the transit speed of the Steering, Throttle, Auxiliary 1 and Auxiliary 2 channels. When
driving your Model, proper Steering and Throttle control are vital. For example, lowering the transit speed of the Steering servo
can help to limit excessive Steering, which will enable you to achieve smoother cornering. In addition, lowering the transit speed
of the Throttle servo High Side can help to ensure smooth Throttle control. This function can be used in conjunction with the
Exponential, ARC or Point Curve functions to double the effect.
Choosing the Channel:
1) From within the RACING menu, scroll UP or DOWN to highlight the SPEED
menu.
The Servo Speed function can be programmed for each of the four channels, however, depending on the current Car Type,
not all channels may be able to be Selected. For example, if your current Car Type features Front and Rear Steering and
Front and Rear Motors (such as Car Type X), only ST and TH channel options will be programmable, however, both Front and Rear
channels will be programmed with the same Programming Values.
Servo Speed Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the
Auxiliary Dial or the Auxiliary Lever. For more information, see the
ASSIGN
Menu
section on pages 33 ~ 38.
Servo transit speed can be slowed in the Forward and the Return to
Neutral directions independently. In addition, you are able to program
a Point on either side of servo travel, then define whether the servo transit
speed is slowed down either Outside or Inside those two Points.

The Anti-Lock Braking function makes it possible to achieve stable Braking even on a slippery surface. With stable Braking, your
Model is better able to trace an exact line under Braking. When the Anti-Lock Braking function is turned ON, the Throttle servo will
pulse when you apply Brake. Different Anti-Lock Braking options can be programmed, including how quickly the Brake pulsates,
the Point at which the Anti-Lock Braking function Starts and more.
The Anti-Lock Braking function is primarily used on gasoline- or glow-powered Models that feature a Throttle servo. It can be used
on an electric Model that uses an Electronic Speed Control, however, if your Electronic Speed Control features a reverse function,
the Anti-Lock Braking function will not operate properly.
The Anti-Lock Braking function operates only when the Throttle Trigger is
moved from Neutral to the Brake Side. Set the hardest Braking you can obtain
from your Model by carefully setting the Anti-Lock Braking function Right before the
tires fully lock up but do not slip and lose traction. Be aware that using the Anti-Lock
Brake function will never result in your Model losing traction under Braking. It only
improves Braking under less than ideal conditions. With ABS ON With ABS OFF
The diagram at Right illustrates the relationship between the Point, Lag, Release,
Hold and Stroke functions, all of which can be programmed separately to suit your
specific Car Type, track conditions and Anti-Lock Braking behavior.
If desired, you can change the behavior of the switch from PUSH (default) to TOGGLE. For more information, see the
Changing the Switch Mode

ALB MENU {ANTI-LOCK BRAKING}RACING
Changing the Point Percentage Value:
The Point percentage value determines the position along the length of Brake Side servo travel that the Anti-Lock Braking function
Activates at when turned ON. For example, if set to 80%, you will have Normal Braking from the Throttle Neutral Point to 79% of
servo travel. At 80% of servo travel and beyond, the Anti-Lock Braking function will Activate when turned ON.
POINT setting range is 5% to 100%. The default setting is 80%.
1) From within the ALB menu, scroll UP or DOWN to highlight POINT > 80%.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Point
percentage value. Increasing the Point percentage value will cause the
Anti-Lock Braking function to Activate later and Decreasing the Point percentage
value will cause the Anti-Lock Braking function to Activate sooner.
Changing the Release and Hold Values:
The Release and Hold values determine the speed at which the Brake pulsates. By changing the Release and Hold values, you
can make the Brake pulsate Faster or Slower. The Release value determines how quickly the Brake moves from the Point setting
to the Stroke setting and the Hold value determines how quickly the Brake moves from the Stroke setting back to the Point setting.
We recommend using equal Release and Hold values, although different values can be used to fine-tune how the Brake
pulsates. Using Lower values make the Brake pulsate Faster and using Higher values make the Brake pulsate Slower.
RELEASE setting range is 0.01s to 1.00s. The default setting is 0.03s.
1) From within the ALB menu, scroll UP or DOWN to highlight RELEASE > 0.03s.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Release
value in Seconds. Increasing the Release value will cause the Brake to move from
the Point setting to the Stroke setting Slower and Decreasing the Release value
will cause the Brake to move from the Point setting to the Stroke setting Faster.
HOLD setting range is 0.01s to 1.00s. The default setting is 0.03s.
3) From within the ALB menu, scroll UP or DOWN to highlight HOLD > 0.03s.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Hold
value in Seconds. Increasing the Hold value will cause the Brake to move
from the Stroke setting back to the Point setting Slower and Decreasing the
Hold value will cause the Brake to move from the Stroke setting back to the
Point setting Faster.
Changing the Lag Value:
The Lag value determines the amount of Delay before the Anti-Lock Braking function Activates after reaching the Point setting.
LAG setting range is 0.00s to 1.00s. The default setting is 0.00s.
1) From within the ALB menu, scroll UP or DOWN to highlight LAG > 0.00s.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Lag value
in Seconds. Increasing the Lag value increases the Delay time to Activate the
Anti-Lock Braking function after reaching the Point setting and Decreasing the
Lag value decreases the Delay time to Activate the Anti-Lock Braking function
after reaching the Point setting.
OFFSET MENU {THROTTLE OFFSET}RACING
The Throttle Offset function allows you to shift the Neutral Point of the Throttle servo to a fixed position, either toward the High
Side or the Brake Side, while still allowing you full control of the Throttle. For example, if you're driving a glow- or gas-powered
Model, you can use the Throttle Offset function to raise the engine idle for starting or you can program the Throttle Offset function
to Increase the engine to a steady idle while you're refueling during a race. If your Model features a separate Brake servo, a Brake
Lock function is featured that can be programmed to apply Brake while the Throttle is increased to keep your Model from moving.
The Throttle Offset function shifts the Neutral Point of the Throttle servo without affecting the High Side or Brake Side End
Points. This allows you to have full control over the Throttle even when the Throttle Offset function is turned ON.

BR-MIX MENU {DUAL BRAKE MIXING}RACING
The Brake Mixing function allows you change the Brake Bias between the Front and Rear Brakes and is used primarily with 1:5th
scale gas-powered Models that use separate Brake servos, although one of the separate Brake servos can be the Brake Side of
the Throttle servo, such as when Car Type III is Selected. The Brake Mixing function slows the transit speed of one or both Brake
servos, which not only allows to slow down the Braking action, but also allows you to set a Delay between them, which results in
you being able to change the Brake Bias.
Brake Delay Programming Values can be changed while you're driving by Assigning the these functions to a Trim Switch or
the Auxiliary Dial. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
The Brake Mixing function is available only when either Car Type III, IV or VII is Selected.
Changing the Brake Delay Percentage Value:
1) From within the RACING menu, scroll UP or DOWN to highlight the BR-MIX
menu.
2) Press the ENTER key to open the BR-MIX menu. BR-DELAY > 0% will be
highlighted.
3) Scroll UP or DOWN to highlight the Brake Delay percentage value you would
like to change, either BR-DELAY or BR2-DELAY.
Which Brake Delay percentage value affects the Front or Rear Brake servo
depends on how your Brake servos are plugged into the receiver and will vary.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Brake
Delay percentage value. Increasing the percentage value will slow the
transit speed of that Brake servo.
5) Press the ENTER key, then repeat steps 3 and 4 to change the other Brake
Delay percentage value, if desired. The larger the difference between the
two Brake Delay percentage values, the greater the Brake Bias.
BR-DELAY and BR2-DELAY setting range is 0% to 100%. The default setting for both channels is 0%.
Setting both Brake Delay percentage values to the same percentage value will result in both Brake servos moving at the
same speed. This allows you slow down the Braking action if that is desired. Using different percentage values will result
in Brake Bias. You may find that you will need to use a larger percentage value to make a noticeable difference in Brake Bias.
TH-HLD MENU {THROTTLE HOLD}RACING
The Throttle Hold function moves the Throttle servo to a fixed position, either toward the High Side or the Brake Side, and is used
primarily with glow- or gas-powered Models. For example, if you're driving a glow- or gas-powered boat, you can use can the
Throttle Hold function to stop your engine with only the press of a button. This feature is often referred to as 'Engine Cut'. Alternately,
you can use the Throttle Hold function to Increase the engine to a steady idle while you're refueling during a race. This feature
is often referred to as 'Idle Up'. If your Model features a separate Brake servo, a Brake ON/OFF function is featured that will allow
you to lock out the Brake servo (ON) or allow you control of the Brake servo (OFF) while the Throttle Hold function is turned ON.
The Throttle Hold function moves the Throttle servo to a fixed position, either
toward the High Side or the Brake Side. When the Throttle Hold function is
turned ON, you will NOT have control of the Throttle. If your Model has a separate
Brake servo and you set the Brake ON/OFF function to OFF, you will still have
control over your Model's Brake. To regain Throttle control, you must turn the
Throttle Hold function OFF.

needing to access the TH-HLD menu. See the notation at the top of the page. In addition, ON and OFF behavior will differ
based on the ACT/INH setting you choose. We recommend using the INH setting. With this setting, the Throttle Hold function will
always be OFF until you turn it ON. If you choose ACT, the Throttle Hold function will always be ON until you turn it OFF.
Changing the Brake Lock-Out Value:
When Car Type II, III, IV,VI or VII is Selected, the Brake Lock-Out function can be programmed, which gives you the option to lock
out the Brake servo(s) or retain control of the Brake servo(s). This gives you the option of controlling your separate Brake servo(s)
to keep your Model from moving, even when your engine's idle Increases when the Throttle Hold function is turned ON. If your
Car Type features two separate Brake channels, such as Car Type IV, the Brake Lock-Out function will affect both Brake channels
equally.
1) From within the TH-HLD menu, scroll UP or DOWN to highlight BR > ON.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Brake
value, either ON or OFF. When set to ON, your separate Brake servo(s) will

The Compensation Mixing function is used to create your own custom Mixes that allow you to control any number of desired
functions in different combinations. For example, you can use the Compensation Mixing function to deploy an air-Brake when
you apply Brake or raise a wing as you Increase Throttle. You could use the Compensation Mixing function to counter-act torque
steer by applying a very slight amount of Steering in one direction when you Increase Throttle. The possibilities are nearly endless.
Compensation Mixes are composed of a Master channel and a Slave channel. The Master channel always controls the Slave
channel. Any of the four channels can be programmed as a Master or a Slave. The same channel can even be programmed as
both a Master and a Slave. Two Rate percentage values can be programmed to determine the direction and amount of travel that
the Slave channel servo moves in relation to the Master channel servo. In addition, an Offset function is featured that allows you
to shift the Neutral Point of the Slave channel servo to center the Slave channel servo or to shift the Slave channel servo's Neutral
Point to change the starting point of your Mix.
Two Compensation Mixers are available, and each can be turned ON separately or both can be turned ON at the same time. A
graph is featured to help visualize the Compensation Mixing changes you make.
Compensation Mixing Programming Values can be changed while you're driving by Assigning these functions to a Trim
Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
This section covers both the Compensation Mixing 1 and Compensation Mixing 2 menus, since programming each of them
is exactly the same. Choose either the C-MIX1 or the C-MIX2 menu depending on which of the two Compensation Mixers
you want to program.
The Compensation Mixing Rate 1 and Rate 2 percentage values determine whether the Compensation Mixer(s) are Active
(turned ON) or Inhibited (turned OFF). When no Rate percentage values are programmed, the Compensation Mixer(s)
will be Inhibited and when a Rate percentage value is programmed, the Compensation Mixer(s) will become Active. To turn
the Compensation Mixer(s) ON and OFF while you're driving, you will need to program the Compensation Mixer(s) with a Rate
value to one Racing Mode (turned ON), then switch to a Racing Mode without any Compensation Mixer Rate values programmed
(turned OFF).

In the example above, Compensation Mixing 1 is programmed as follows: MASTER > ST, SLAVE > TH, RATE1 > 10%, RATE2 > 10%
and OFFSET > 0. When you move the Steering Wheel 100% in each direction, the Steering servo will travel 100% in each direction
and at the same time, the Throttle servo will travel 10% in each direction.
Compensation Mixing Rate percentage values are a Ratio of Slave channel servo travel to Master channel servo travel. For
example, if both Rate percentage values are set to 10%, the Throttle servo will travel 1:10th the amount as the Steering servo
travels in both directions. Compensation Mixes are Linear throughout the entire range of travel. If a Rate value of 0% is chosen, the
Slave servo will not move in that direction.

direction). To avoid damage to your Model, we don't suggest programming Rate percentage values that exceed your Slave
channel servo End Points.
Changing the Channel Offset Value:
The Offset function allows you to shift the Neutral Point of the Slave channel servo to compensate for any Master channel servo
Trim or to change the starting point of your Mix.
1) With the Master channel control centered, check the Master Travel Indicator
at the bottom of the graph to see if any Master channel Trim is displayed.
2) From within the C-MIX1 menu, scroll UP or DOWN to highlight OFFSET > 0.
3) Press the ENTER key, then scroll UP or DOWN to choose the desired Slave
channel Offset value. Increase or Decrease the Offset value to move the
vertical axis in the desired direction.
OFFSET setting range is -150 to 150 . The default setting is 0%.
Following the example in the diagram at Right, set the Rate 1 percentage value to
0% and the Rate 2 percentage value to -50%, then set the Offset value to -100. The
full range of Mixing travel can now be adjusted in one direction when turning the
Auxiliary Dial counter-clockwise.
This same technique can also be used if you're using the Auxiliary Lever to
control either Auxiliary 1 or Auxiliary 2.
When the Auxiliary Dial is programmed to control Auxiliary 1 or Auxiliary 2 and you choose AUX1 or AUX 2 (or
#AUX1 or #AUX2) to be the Master channel, by setting the Offset value to 100 or -100, the Auxiliary Dial can
control the full range of Mixing travel in one direction, instead of half the Mixing travel in one direction and half the
Mixing travel in the other direction. This is useful if you want the full range of Mixing travel in only one direction.
Setting the Offset value to a value greater than -100 or 100 will shift the Neutral Point of the Slave channel
servo beyond the operation range of the Auxiliary Dial and is not recommended.

ACKER MENU {ACKERMAN ANGLE ADJUSTMENT}RACING
The Ackerman function allows you to change the Steering angle of the Front tires independently to prevent the tires from slipping
during turns. Being able to change the Ackerman Angle can help improve your Model's high-speed cornering and improve tire
wear. In general, your Model will corner better if the inner tire turns in at a sharper angle than the outer tire. The Ackerman function
allows you reduce the turn-in angle of the outer tire, which increases the turn-in angle of the inner tire relative to it.
Ackerman Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the
Auxiliary Dial or the Auxiliary Lever. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
The Ackerman function is available only when either Car Type V, VI or VII is Selected.
Changing the Ackerman Angle Percentage Values:
1) From within the RACING menu, scroll UP or DOWN to highlight the ACKER
menu.
2) Press the ENTER key to open the ACKER menu. LEFT-ST L > 100% will be
highlighted.
3) Scroll UP or DOWN to highlight the Ackerman Angle percentage value you
would like change. Choose from either LEFT-ST (Left Steering) Left or Right, or
RIGHT-ST (Right Steering) Left or Right.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired
Ackerman Angle percentage value. Reducing the Ackerman Angle percentage
value will reduce the amount of control throw in that the direction for that
specific servo.
5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired
Ackerman Angle percentage values.
In general, you want the inner tire to turn in more than the outer tire when turning both Right and Left (unless you're running
on an oval track). In order to achieve this, you will need to reduce the control throw of the outer tire in both the Right and
Left directions by reducing those Ackerman Angle percentage values. The percentage values you will need to change will vary
depending on several factors, so you'll need to experiment to find the ones you need to reduce to achieve the desired results.
LEFT-ST L and R and RIGHT-ST L and R setting range is 0% to 100%. The default setting for both channels is 100%.
R-DLY MENU {RACING MODE DELAY}RACING
The Racing Mode Delay function allows you to program a Delay for each of the four channels to help prevent drastic changes in
channel function settings when switching between Racing Modes. For example, you might have one Dual Rate setting for Racing
Mode 1 and a different Dual Rate setting for Racing Mode 2. The Racing Mode Delay function allows you to program a Delay in
the Steering channel so that the transition to the different Dual Rates when you switch back and forth between Racing Modes
is smooth and less noticeable.
Racing Mode Delay Programming Values can be changed while you're driving by Assigning these functions to a Trim
Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the
ASSIGN Menu
section on pages 33 ~ 38.
Changing the Racing Mode Delay Percentage Values:
1) From within the RACING menu, scroll UP or DOWN to highlight the R-DLY

3) Scroll UP or DOWN to highlight the desired Code Auxiliary value you would
like to change.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Code
Auxiliary value.
CODE1, CODE2, CODE3, CODE4 and CODE5 setting range is -100 to 100. The default setting for all Code Auxiliary functions
is 0 (OFF).
5) Press the ENTER key again, then repeat steps 3 and 4 to change any other desired Code Auxiliary values.
3) Scroll UP or DOWN to highlight the desired channel you want to change the
Racing Mode Delay percentage value for.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Racing
Mode Delay Percentage value. Increasing the Racing Mode Delay Percentage
value will Increase the Delay when switching between Racing Modes.
The Racing Mode Delay function changes the speed of the servos as they move to their new positions when you switch
between Racing Modes. The Higher the Racing Mode Delay percentage value, the Slower the servos will transition to their
new positions when you switch Racing Modes, but the smoother the transition will be. You will need to experiment with different
percentage values to find a happy medium of smooth, yet quick transition. When the Racing Mode Delay Percentage value is set
to 0%, there will be no Delay and the transition between Racing Modes will be immediate.
This section covers both the Code Auxiliary 1 and Code Auxiliary 2 menus, since programming each of them is exactly the
same. Choose either the CODEAX1 or the CODEAX2 menu depending on which of the two Code Auxiliary functions you
want to program.

TELEMETRY CONNECTIONS AND MOUNTING REFERENCE
Overview:
The RX-461 and RX-462 receivers each feature two Temperature Sensor Inputs and one RPM Sensor Input, in addition to the
Voltage Sensor built into the receiver. Temperature and RPM Sensors can be installed into your Model to give you Temperature
and RPM or Speed feedback in real-time displayed on the transmitter's TELEMETRY screen.
The range of the Telemetry System is approximately 260 feet (80 meters), although the range can vary based on many
environmental factors. Use the Telemetry Signal Indicator to determine the quality of the Telemetry Signal.
When used with an Airtronics 2.4GHz FH4T Telemetry-capable surface receiver, such as the RX-461 or RX-462, and up to two
Temperature Sensors and an RPM Sensor (all available separately), Telemetry Data, such as RPM or Speed, Temperature, and
Receiver Voltage can be viewed on the M12S transmitter's TELEMETRY screen.
This section details connecting the RPM and Temperature Sensors to the RX-461 and/or RX-462 receiver and how to mount those
Sensors into your Model. For more information about the specifics of either receiver, refer to the User's Guide included with your
receiver.
For more information about viewing Telemetry Data on the TELEMETRY screen, see the
TELEMETRY Screen Overview
section
on pages 22 ~ 23. For more information about choosing Telemetry options, see the
LOG SETUP Menu
section on pages 48 ~ 56.
Plugging the Telemetry Sensors into the Receiver:
1) Carefully pry up and remove the plastic cover from over the Telemetry Sensor Input Ports on the receiver.
2) Plug the Telemetry Sensor(s) into their respective Input Ports in the receiver. The Temperature Sensor can be plugged into
either the TEMP 1 or the TEMP 2 Input Port and the RPM Sensor is plugged into the RPM Input Port. The Sensor Plugs are
indexed so they can be plugged in only one way.
Make sure to push the Sensor Plugs firmly in place to ensure a good connection. When routing Sensor Wires inside your
Model, be careful that they cannot come into contact with any moving parts. The Sensor Wires should be securely mounted
and protected against damage. In addition, install the dust covers included with your receiver to prevent dirt and debris from
getting into any unused Input Ports.
1) Mount the RPM Sensor to an aluminum or ABS angled bracket, then mount the bracket to your Model, making sure that it's
held securely in place. For optimal operation, the Sensor Pickup should be positioned approximately 1mm away from the
rotating part (flywheel, spur gear, pinion gear etc.)
2) Cut one of the two reflective decals included with the RPM Sensor into an ~2mm diameter and apply it to the rotating part, so
that as the part rotates, the reflective decal passes in Front of the Sensor Pickup. If the rotating part is metallic-colored (silver,
aluminum, chrome, etc.), use the Black reflective decal and if the rotating part is dark-colored (black, blue or another dark
color), use the White reflective decal.
When installed, it's important that the Sensor Pickup face the rotating part and that the Black or White reflective decal is
positioned so that it passes in Front of the Sensor Pickup. It's also important that the reflective decal contrasts with the rotating
part it's applied to and that the Sensor Pickup is mounted approximately 1mm away from the rotating part.
After installing the RPM Sensor and connecting it to your receiver, the RPM Sensor must be calibrated. For more information,
see the
RPM and Speed Telemetry Data Display Options
section on pages 48 ~ 50.
Mounting the RPM Sensor:
The RPM Sensor uses infrared technology to record RPM data from a rotating part, such as a flywheel or a spur gear. One Black
and one White reflective decal is included that is attached to the rotating part so the Sensor Pickup can 'see' it.

Mounting the Temperature Sensor:
1) Secure the Sensor End directly against the part of your engine, motor, battery or other object you want to monitor temperature
readings from, using either a nylon cable tie or high-temperature clear tape. For example, to monitor the cylinder head
temperature of your glow-powered Model, the best place to secure the Sensor End is where the bottom of the cylinder head
meets the top of the engine case. The Sensor End can be held in place using a nylon cable tie wrapped around your engine.
To monitor the temperature of your battery pack or electric motor, high-temperature clear tape can be used to secure the
Sensor End to the exact spot you want to monitor.
