2) Measuring in inches (or centimeters if using KM/H) from where you set your Model on the ground, slowly push your Model
and measure the distance covered to complete 10 full revolutions of the RPM sensor (the Bind LED on your receiver will flash
10 times, indicating 10 full revolutions).
4) Press the ENTER key, then scroll UP or DOWN to change the 10Count Distance
value to match the measurement obtained in step 2 above. For example, if
your Model traveled 2 feet (61cm) to complete 10 full revolutions, enter 24.0
(for MPH) or 61 (for KM/H).
10COUNT DIST setting range is 0.5 to 118.0 for MPH and 1 to 300 for KM/H. The
default setting is 12.0 for MPH and 30 for KH/H.
IMPORTANT: Changing the 10Count Distance value will change the Maximum Scale value. After calibration, you should reset
the Maximum Scale value back to the value you chose previously.

M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDE
EPA MENU {CHANNEL END POINT ADJUSTMENTS}SETUP
The End Point Adjustment function allows you to adjust servo travel in each direction. This makes it possible to balance servo
travel in both directions and set the maximum desired amount of servo travel. For example, on a gas-powered Model, if you pull
the Throttle Trigger and the carburetor does not open completely, you can Increase the Throttle High End Point Adjustment so
that the carburetor opens completely. Another example is with Steering. If your Model turns sharper to the Right than to the Left,
you can Increase the Steering Left End Point Adjustment to balance the Steering.
The End Point Adjustment function can be adjusted for the Steering channel (Right and Left), the Throttle channel (High and
Brake), the Auxiliary 1 channel (High and Low) and the Auxiliary 2 channel (High and Low).
Before making End Point Adjustments, the servo horn needs to be centered. Install the servo horn onto the servo, making
sure it's as close to being centered as possible, then use the Servo Sub-Trim function to center the servo arm exactly. For
more information, see the
SUB TRIM Menu
section on page 63.
Changing the Channel End Point Adjustment Percentage Values:
1) From within the SETUP menu, scroll UP or DOWN to highlight the EPA menu.
2) Press the ENTER key to open the EPA menu. The cursor will default to either
ST > L100% or ST > R100%.
3) Scroll UP or DOWN to highlight the desired End Point Adjustment percentage
value you would like to change.
4) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
End Point Adjustment percentage value. Increasing the percentage value will
Increase servo travel in that direction and Decreasing the percentage value
will Decrease servo travel in the that direction.
If you're using an Electronic Speed Control, the Throttle High and the Throttle Brake End Point Adjustment percentage
values are both generally set to 100%, although the Throttle High direction may need to be increased to achieve full power.
In some cases, Throttle and Brake End Point Adjustments can also be set directly via the Electronic Speed Control.
5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired
End Point Adjustment percentage values.
ST L and R setting range is 0% to 150%, TH H and B setting range is 0% to 150%, AUX1 H and L setting range is 0% to 150%
and AUX2 H and L setting range is 0% to 150%. The default setting for all channels is 100%.
End Point Adjustment percentage values should not be increased to the point where your
linkages and servos Bind when moved all the way to the Right or Left. Binding will cause
the servos to 'buzz', resulting in a quicker loss of receiver battery power and eventual damage to
the servos or to your Model.

TR
SUB TRIM MENU {SERVO CENTERING}SETUP
The Sub-Trim function allows you to correct the Neutral Trim setting for the Steering, Throttle, Auxiliary 1 and Auxiliary 2 channels,
making it possible to center the Trim Switches while ensuring the servo horns remain centered.
It's not unusual that when you center a servo and install the servo horn, the servo horn is not exactly centered. The Sub-Trim
function allows you to center the servo horn exactly, without altering the servo End Point travel. This is especially useful
when using a Mix, such as Four Wheel Steering Mixing. For example, you can use the Sub-Trim function to adjust the Neutral
Trim setting of your Front and Rear Steering servos independently to ensure your Model tracks straight.
Before changing the Sub-Trim values you should set the Steering and
Throttle Trim to 0% using the Trm1 and Trm2 Trim Switches.
Changing the Servo Sub-Trim Values:
1) Install the servo horn (or servo saver for the Steering servo) onto your servo,
making sure that the servo horn (or servo saver) is as close to being centered
as possible. In some cases, you can get the servo horn closer to being
centered by rotating the servo horn 180º and reinstalling it.
2) From within the SETUP menu, scroll UP or DOWN to highlight the SUB TRIM
menu.
3) Press the ENTER key to open the SUB TRIM menu. The cursor will default to
ST > 0.
4) Scroll UP or DOWN to highlight the desired Sub-Trim value you would like to
change.
5) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
Sub-Trim value only enough to center the servo horn.
6) Press the ENTER key, then repeat steps 4 and 5 to change any other desired
Sub-Trim values.
ST setting range is R150 to L150, TH setting range is H150 to B150, AUX1 setting range is H150 to L150 and AUX2 setting range
is H150 to L150. The default setting for all channels is 0.
IMPORTANT: Changing the Sub-Trim values will alter the servo's End Points. After changing the Sub-Trim values, use the End
Point Adjustment function to Reset the servo End Point Adjustment Percentage Values. For more information, see the
Changing
the Channel End Point Adjustment Percentage Values
section on the previous page.

POINT AUX1 MENU {AUXILIARY 1 POINT VALUES}SETUP
The Point Auxiliary function allows you to program the Auxiliary 1 servo to move up to 6 different Points along its travel, then cycle
through those Points using one of the Trim Switches or the Rotary Dial. For example, if your Model requires a separate 3-position
or more switch to operate a feature, the Point Auxiliary function can be customized to control this. This section details how to
change the actual Point values. For example, if you have 4 Points programmed, you can change the Point values to cycle your
servo from 0 to 20 to 40 to 60 degrees and back again.
Use one of the five Trim Switches or the Auxiliary Dial to cycle through the Point Positions while you're driving. The Auxiliary Lever
is not suitable for use in this situation. The Point Auxiliary function can be toggled OFF and ON while you're driving by Assigning

FEELING MENU {STEERING AND THROTTLE CHANNEL RESPONSE TIME}SETUP
The Feeling function allows you to adjust the Response Time of the Steering and Throttle channels to fine-tune the sensitivity of
these controls. The M12S transmitter has an extremely fast Response Time (Latency), which results in the driver feeling extremely
connected to their Model. This ultra-fast Response Time can be felt by the racer, particularly during on-road racing where the vehicle
reacts extremely quickly to control inputs due to the increased traction between the vehicle and the track. After getting used to
this fast Response Time, it allows for quicker, smoother control of your Model, which gives you an advantage over other drivers.
Some users may find that the Response Time is in some cases too fast, therefore, we've made it adjustable to suit the driver's
driving style, Car Type and track conditions.
The Feeling function works not only with Airtronics FH4T and FH4 receivers, but also with FH3 and FH2 receivers as well.
Changing Steering and Throttle Response Time Values:
1) From within the SETUP menu, scroll UP or DOWN to highlight the FEELING
menu.
2) Press the ENTER key to open the FEELING menu. ST > 5S will be highlighted.
3) Scroll UP or DOWN to highlight the desired channel you would like to change
the Response Time value for, either ST (Steering) or TH (Throttle).
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Response
Time value for that channel. When set to 0, Response Time is similar to the
Airtronics M11X (approximately 5ms average). Increasing the 'S' value
Increases Response Time and Increasing the 'F' value Decreases Response Time.
ST and TH setting range is 5S to 1S, 0 and 1F to 5F. The default setting is 5S.
F /S {FAIL SAFE}SETUP
The Fail Safe function automatically moves the servos to a predetermined position in the event that the signal between the
transmitter and the receiver is interrupted, whether due to signal degradation or to low transmitter battery.
Several different options are available. The Fail Safe function can be set to HOLD the servos in the last position they were in when
the signal was lost or each of the servos can be set to move to a custom position when the signal is lost. For example, the Throttle
servo (or ESC) can be programmed to move toward the Brake Side to engage the Brakes and stop your Model, or, if you're
driving a gas- or glow-powered boat, the Fail Safe function could be set to Lower the Throttle servo (or ESC) to idle and turn the
rudder slightly Left or Right so that the boat will continue in slow circles.
Fail Safe settings can be programmed for each of the four channels individually. In addition, Fail Safe settings are Model-specific,
meaning you can have different Fail Safe settings for each of your Models. The Fail Safe settings will be retained even if the
transmitter loses power or if the transmitter and receiver must be paired again.
Three Fail Safe options are available for each channel as described below:
FREE - Fail Safe is Disabled for this channel. Servos can move freely when the signal is lost.
HOLD - When Fail Safe Activates, the servo will be held in the last position it was in when the signal was lost.
% (PERCENTAGE) - When Fail Safe Activates, the servo will travel to the programmed position when the signal is lost.
WARNING: The Fail Safe function will NOT OPERATE if the receiver loses power. For example, if the receiver battery were to
die or come unplugged. It will operate only if the transmitter and receiver signal is interrupted or if the transmitter loses power.
