14.F /S (FAIL SAFE)
PROGRAM
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
setting 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 moves to the Brake Side to engage the brakes and stop your model. If you're driving a gas- or glow-powered boat, the
Fail Safe function could be set to lower the throttle to idle and turn the rudder slightly left or right so that the boat will continue
in slow circles.
In addition, a Receiver Battery Voltage Fail Safe function is available which allows you to set a custom voltage that the Receiver
Battery Fail Safe function will Activate at. This is useful if you're using servos with a higher than normal current draw that might
run out of power before the receiver does.
IMPORTANT: The Fail Safe function will NOT OPERATE if the receiver loses power. It will operate only if the transmitter and
receiver signal is interrupted or if the transmitter loses power.
Setting the Fail Safe:
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 Model in memory. 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.
1) From the Top Screen, press the ENTER key to open the Programming Menu list.
2) Scroll UP or DOWN to highlight the F/S menu, then press the ENTER key. The F/S menu
will be displayed and [ST]:FREE will be highlighted.
3) Scroll UP or DOWN to highlight the desired channel you would like to change the Fail
Safe option for.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Fail Safe option for
that channel. If you choose to program a % value, see step 5 below.
F/S setting range is FREE, HOLD, or %. The default setting is FREE.

14.F /S (FAIL SAFE)
PROGRAM
5) To program a Fail Safe percentage value, move the control the amount you want the
servo to move to when the Fail Safe function Activates and HOLD it in that position,
then press and HOLD the ENTER key until an audible tone sounds. The percentage and
direction the servo will travel will be displayed. For example, to set the Throttle Brake to
engage when the Fail Safe function Activates, push the throttle trigger toward the Brake
side the desired amount, HOLD the throttle trigger in that position, then press and HOLD
the ENTER key. The percentage value programmed will be indicated by two hash marks
on the Servo Monitor.
6) Check to ensure your Fail Safe settings are working properly. Make sure that both the transmitter and receiver are turned
ON, then, while someone is holding your model, turn the transmitter OFF. The servos should react correctly based on the
Fail Safe values chosen.
The Fail Safe settings will be retained even if the transmitter loses power or if the transmitter and receiver must be
paired again.
When using an FH2 receiver with your transmitter, these Fail Safe features are not supported. In this case, the Fail Safe
function must be programmed directly through the receiver. For more information, follow the Fail Safe Programming
instructions provided with your FH2 receiver.
The Receiver Battery Voltage Fail Safe function is designed to alert you when your receiver battery requires recharging. This
ensures that the receiver battery's voltage doesn't drop so low that your servos aren't provided adequate voltage to operate
optimally. When Activated, the throttle servo will move to the predetermined position you programmed in step 5 in the Setting the
Fail Safe section above. If this occurs, recharge or replace your receiver batteries.
WARNING: This function is designed for use with glow- or gas-powered Models that use a separate receiver battery pack.
Do NOT use this function with an electric Model that uses the motor battery to power the servos and receiver.
PROGRAM
Setting the Receiver Battery Voltage Fail Safe Function:
If FREE or HOLD is chosen for the Throttle channel, you cannot Activate the Receiver Battery Voltage Fail Safe function.
A % value must be chosen for the Throttle channel to be able to program and use the Receiver Battery Fail Safe function.
The Receiver Battery Voltage Fail Safe function works only with FH3 and FH4T receivers.
1) Follow steps 1 through 5 in the Setting the Fail Safe section to program a Throttle Fail
Safe percentage value.
2) From within the F/S menu, press the ENTER key, then scroll DOWN to highlight
[B-F/S] OFF.
3) Press the ENTER key, then scroll UP or DOWN to choose the desired Receiver Battery
Fail Safe Voltage value. Many factors, such as the current draw of your servos and how
many servos you're using, etc., will determine the value to use. A good starting point
would be 3.7V. If it appears your servos are slow or not producing adequate torque what
that Voltage value is reached, Increase the Voltage value.
F/S B-F/S setting range for FH4T receivers is OFF and 3.5V to 7.4V. F/S B-F/S setting range for FH3 receivers is OFF and
3.5V to 5.0V. The default setting is OFF regardless of the Modulation Type chosen.
15.LOGGER (TELEMETRY LOG)
PROGRAM
The Telemetry Log function allows you to view a log of the Telemetry Data that is sent from the receiver to the transmitter. You
are able to view Telemetry Data for both Temperature outputs, the RPM output and the receiver's Voltage. This information can
be used to track specific information about your model, such as cylinder head temperature if you're running a nitro-powered
model or battery temperature if you're running an electric model and much more. The interval that Telemetry Data is read and
stored can be adjusted so that Telemetry Data can be stored for up to 90 minutes of use. The Telemetry Log can store 120
different data entries at intervals ranging from 00.1 seconds to 45.9 seconds.

02.BIND (BINDING, MODULATION TYPE AND SERVO OPERATING MODE)
SYSTEM
The Binding function allows you to Bind the transmitter and receiver pair. When new, it is necessary to pair the transmitter
and receiver to prevent interference from transmitters operated by other users. This operation is referred to as Binding. Once
the Binding process is complete, the setting is remembered even when the transmitter and receiver are turned OFF. Therefore,
this procedure usually only needs to be done once. In addition, the Modulation Type and Servo Operating Mode can also be
changed to suit your specific setup.
Changing the Modulation Type:
The Modulation Type function allows you to choose the transmitter Modulation Type. The Modulation Type can be changed
to match the receiver you're using. For example, if you wish to use an Airtronics 2.4GHz FH2 receiver with your transmitter,
you would need to change the Modulation Type to FH2 prior to Binding your transmitter and receiver. Modulation Type
is model-specific, meaning that you can have one model use FH4T Modulation and another model use FH2 Modulation, etc.
The Modulation Type must be chosen prior to Binding the transmitter and receiver. Make sure the Modulation Type you
choose matches the Modulation Type of the receiver you're using.
1) From within the SYSTEM menu, scroll UP or DOWN to highlight the BIND menu.
2) Press the ENTER key. The BIND menu will be displayed and [RF MODE]:FH4T will be
highlighted.
3) Press the ENTER key, then scroll UP or DOWN to select the desired Modulation Type,
then press the ENTER key a second time. Set to (Modulation Type) NO/YES will be
displayed.
4) Scroll DOWN to highlight YES, then press the ENTER key.
The following Modulation Type options are available:
FH2 - Select this Modulation Type when using an Airtronics 2.4GHz FH2 surface receiver.
FH3 - Select this Modulation Type when using an Airtronics 2.4GHz FH3 receiver.
FH4T - Select this Modulation Type when using an Airtronics 2.4GHz FH4T Telemetry receiver.
FH3F/FH4FT - These Modulation Types are NOT used in North America. They are typically used in France.
IMPORTANT: Not all BIND menu functions are supported by all Modulation Types. Only supported functions will be
displayed once a Modulation Type is chosen. For example, the FH2 Modulation Type does not support the ability to change
the Servo Operating Mode.
Changing the Channel Mode - FH2 Modulation Type Only:
When the FH2 Modulation Tyep is selected, you can choose to operate the transmitter in either 2-Channel Mode or 4-Channel
Mode. This option is available ONLY when [RF MODE] FH2 is selected.
1) From within the BIND menu, scroll DOWN to highlight [CH]:4ch.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Channel Mode.
Selecting 2CH will enable 2-channel operation (Steering and Throttle). Selecting 4CH
will enable 4-channel operation (Steering, Throttle, Auxiliary 1 and Auxiliary 2).
BIND CH setting range is 2CH and 4CH. The default setting is 4CH.
Changing the Servo Operating Mode:
The Servo Operating Mode function is used to optimize the radio control system to suit the type of servos you're using in your
model. For example, using the SHR setting with Digital servos will Increase the servo's response time, even above the
manufacturer's stated specification. If you're using Airtronics SRG Digital servos, you can use the SSR setting for the fastest
response time. The combination of using Digital servos and using the correct Servo Operating Mode results in the ultimate feel
and response, making you feel more in control of your model than ever.

SYSTEM
1) From within the BIND menu, scroll UP or DOWN to highlight the desired channel you
would like to change the Servo Operating Mode for. Choose from either [ST]:NOR
(Steering), [TH]:NOR (Throttle), [A1]:NOR (Auxiliary 1) or [A2]:NOR (Auxiliary 2).
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Servo Operating
Mode option for that channel.
SERVO OPERATING MODE setting range is NOR, SHR and SSR. The default setting is
NOR. SSR Operating Mode is not supported when the FH3 or FH3F Modulation Type
is selected. No Servo Operating Modes are supported when the FH2 Modulation Type
is selected.
IMPORTANT INFORMATION ABOUT SERVO OPERATING MODES:
If you're using Analog servos in your model, DO NOT use SHR or SSR Servo Operating Mode for those channels. Use the
NOR (Normal) Servo Operating Mode with Analog servos. Using SHR or SSR Servo Operating Mode with Analog servos can
result in poor performance or even damage to the servos or the receiver! In some cases, the servo may not operate at all.
Not all ESCs are compatible with SHR or SSR Servo Operating Modes. If your ESC does not operate correctly, change the
Servo Operating Mode to NOR (Normal) for that channel (or channels).
SHR and SSR Servo Operating Modes should only be used with Digital servos. While the SHR Servo Operating Mode can be
used with any brand of Digital servo, the SSR Servo Operating Mode should ONLY be used with Airtronics SRG Digital servos.

SWITCH (Push-Button Switch Key Assignments)
The Key Assignments function allows you to assign the ON/OFF control of various functions to Push-Button Switches Sw1 and
Sw2. This allows you to use the Push-Button Switches to turn functions OFF and ON during use. One function can be assigned
to each Push-Button switch, although both Push-Button Switches can be OFF or ON at the same time. In addition, the ON/OFF
behavior of some Push-Button Switch Key functions can be changed.
When you program a function, that function is ON (Active) by default, unless the function's default ON/OFF value is OFF
as noted in the table below. To toggle the function OFF and ON it must be assigned to a Push-Button Switch.
This table shows the different functions that can be programmed to the two Push-Button Switches:

03.KEY ASSIGN (KEY ASSIGNMENTS)
SYSTEM
Changing the Auxiliary Lever Function:
In general, the Auxiliary Lever is used to control Auxiliary 1 Channel 3 or Auxiliary 2 Channel 4. Adjusting the High and Low
Tweak values determines how far and in which direction the Auxiliary servo travels when the Auxiliary Lever is moved Up and
Down. For example, if you assign AUX2 to the Auxiliary Lever and adjust the Tweak values to +50 and -50, the Auxiliary 2 servo
will be centered when the Auxiliary Lever is centered and will travel 50% in one direction when the Auxiliary Lever is moved Up
and travel 50% in the other direction when the Auxiliary Lever is moved Down. This allows you to use the Auxiliary Lever like a
2- or 3-position switch.
In addition, the Auxiliary Lever can be used to control the same parameter functions as the Trim Switches and the Rotary Dial.
For example, if you assign TRIM-ST and adjust the Tweak values to +100 and -100, the Auxiliary Lever will control Steering
channel Trim. The direction and amount the Trim moves when you move the Auxiliary Lever Up or Down is dependent on the
Positive and Negative Tweak values.
To control either the Auxiliary 1 or the Auxiliary 2 servos using the Auxiliary Lever, the Auxiliary Type in the AUX TYPE menu
must be either STEP AUX or POINT AUX. For more information, see the Auxiliary Type section on pages 59 and 60.
When you use the Auxiliary Lever to control a function, such as Steering Dual Rate or
Exponential, the change in values will not be displayed in a pop-up window like they
are when you use the Trim Switches or the Rotary Dial to make the same changes. Instead,
the current position of the Auxiliary Lever is displayed on the Top Screen.
1) From within the KEY ASSIGN menu, scroll UP or DOWN to highlight LEVER.
2) Press the ENTER key. The LEVER menu will be displayed and FUNCTION AUX2 will be
highlighted.
3) Press the ENTER key, then scroll UP or DOWN to choose the desired function for the
Auxiliary Lever. A list of functions that can be assigned to the Auxiliary Lever is shown in
the table on pages 55 and 56.
Changing the High and Low Tweak Values:
The High and Low Tweak values determine the direction and amount of Auxiliary 1 or Auxiliary 2 servo travel. In addition, the
High and Low Tweak values determine the direction and amount of parameter function changes, such as Steering Trim or the
Anti-Lock Braking Point percentage value.
1) From within the LEVER menu, scroll DOWN to highlight TWEAK(H) +100.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired High Side Tweak
value. Increasing the Tweak value will increase servo travel in the High Side direction
and decreasing the Tweak value will decrease servo travel in the High Side direction.
Using a negative value will change the direction of servo travel.
LEVER TWEAK(H) setting range is -100 to +100. The default setting is +100.
3) Scroll DOWN to highlight TWEAK(L) -100.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Low Side Tweak
value. Decreasing the Tweak value will increase servo travel in the Low Side direction
and increasing the Tweak value will decrease servo travel in the Low Side direction. Using
a positive value will change the direction of servo travel.
LEVER TWEAK(L) setting range is -100 to +100. The default setting is -100.

04.TRIM TYPE (TRIM TYPE)
SYSTEM
The Trim Type function allows you choose the way servo Trim and servo End Point Adjustments interact with each other. When
you apply Trim to a servo, the Neutral Point of the servo shifts toward the High Side or the Low Side. When you do this, the servo
travels less in one direction and more in the other direction because the servo End Points are stationary. In order to balance the
servo travel, you would need to manually readjust the servo End Points. Using the Trim Type function allows you to make the
servo End Points shift toward the High Side or the Low Side when you apply Trim. This maintains balanced servo travel without
the need to manually readjust the servo End Points.
The Trim Type function does not effect servo Sub-Trim. It only effects servo Trim that's input using the Trim Switches, Rotary
Dial or Auxiliary Lever. Servo Sub-Trim, which is different, always uses Parallel Trim.
Two Trim Types are available:
CENTER - When Selected, servo End Points are stationary. In order to balance servo travel, you would need to
manually readjust the servo End Points, if desired.
PARALLEL - When Selected, servo End Points shift toward the High Side or the Low Side automatically
when you apply Trim. This maintains balanced servo travel without the need to manually readjust the
servo End Points.
Changing the Trim Type:
1) From within the SYSTEM menu, scroll UP or DOWN to highlight the TRIM TYPE menu.
SYSTEM
2) Press the ENTER key. The TRIM TYPE menu will be displayed and [ST] CENT will be
highlighted.
3) Scroll UP or DOWN to highlight the desired channel you would like to change the Trim
Type option for. Choose from either [ST] CENT (Steering), [TH] CENT (Throttle), [AUX1]
CENT (Auxiliary 1) or [AUX2] CENT (Auxiliary 2).
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Trim Type option
for that channel.
TRIM TYPE setting range is CENT and PARA. The default setting for all channels is CENT.
05.AUX TYPE (AUXILIARY TYPE)
SYSTEM
The Auxiliary Type function allows you choose which Auxiliary function is assigned to Auxiliary 1 Channel 3 or Auxiliary 2
Channel 4. One Auxiliary function can be assigned to each Auxiliary Channel and both Auxiliary Channels can be Active and
controlled at the same time using different controls. For example, you can control Auxiliary 1 Channel 3 using the Rotary Dial
and Auxiliary 2 Channel 4 using the Auxiliary Lever.
For details about programming and using each of the Auxiliary functions, in addition
to selecting AUX Type Modes, see the Auxiliary 1 Programming section on pages 27
through 33 or the Auxiliary 2 Programming section on pages 34 through 40.

06.TH TYPE (THROTTLE TYPE)
SYSTEM
The Throttle Type function allows you to change the proportion between Throttle High Side servo travel and Throttle Brake Side
servo travel. In the default configuration, the Throttle Type is set to F70:B30. This Throttle Type shifts the throttle Neutral Point
toward the Brake Side, resulting in more servo travel toward the High Side and less servo travel toward the Brake Side. Some
users may prefer the proportion between Throttle High Side servo travel and Throttle Brake Side servo travel to be balanced
(F50:B50). The F70:B30 Throttle Type is most common for general use and racing, while the F50:B50 Throttle Type is most
common for Rock Crawling.
Two Throttle Types are available:
F70:B30 - When Selected, the Throttle Neutral Point is shifted toward the Brake Side which provides more
High Side servo travel and less Brake Side servo travel. This is most common for general use and racing.
F50:B50 - When Selected, the Throttle Neutral Point is centered, which provides the same amount of
High Side and Brake Side servo travel. This is most common for Rock Crawling.
Changing the Throttle Type:
1) From within the SYSTEM menu, scroll UP or DOWN to highlight the TH TYPE menu.
2) Press the ENTER key. The TH TYPE menu will be displayed and MODE F70:B30 will be
highlighted.
3) Press the ENTER key, then scroll UP or DOWN to choose the desired Throttle Type
option.

1mph to 335mph (1km/h to 539km/h). The default setting is 34mph (54km/h). The Maximum Speed setting range will vary
based on the 10 Count Distance value programmed when you calibrate the RPM Sensor. For more information, see the
Calibrating the RPM Sensor section on page 67.
Calibrating the RPM Sensor - Changing the 10Count Distance Value:
The 10Count Distance value can be changed if you've Selected UNIT MPH or UNIT KM/H. By changing the 10Count Distance
value you are able to calibrate the RPM sensor to read your specific model's actual speed, in either MPH or KM/H.
RPM Sensor calibration is only required if you choose to use the RPM Sensor to display MPH or KM/H. Calibration is
not required if you're displaying RPM.
Prior to calibrating the RPM sensor, you must connect the RPM sensor to your receiver and correctly install the RPM sensor
into your model. For more information, see the Telemetry Connections and Mounting section on pages 69 and 70.
IMPORTANT: When the reflective tape attached to your model's spur gear, pinion gear, etc., crosses the RPM sensor, the
Bind LED on the receiver will flash green once, indicating 1 full revolution. Use this as a guide during the calibration process.
1) With your transmitter and receiver turned ON, and with an Active Telemetry connection, place your model on the ground.
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 green 10 times, indicating 10 full revolutions).
SYSTEM

feet (61cm) to complete 10 full revolutions, enter 24.0in (61cm).
TELEMETRY 10COUNT DIST setting range is 0.5in to 118.0in (1cm to 300cm). The default setting is 12.0in (30cm).
IMPORTANT: Changing the 10Count Distance value will change the Maximum Speed value. After calibration, you should
reset the Maximum Speed value back to the value you chose previously.
TELEMETRY SETTING (Telemetry ON /OFF and Telemetry Log Options)
The Telemetry Setting allows you to choose whether the Telemetry System is turned ON or OFF and change the interval that
Telemetry Data is read and stored.
The interval that Telemetry Data is read and stored can be adjusted so that Telemetry Data can be stored for up to 90 minutes

is recorded. The Telemetry Log can store up to 120 separate entries. If the Log Step value is set to 00.1 seconds, the Telemetry
Log can record for 12 seconds. If the Log Step value is set to 45.1 seconds, the Telemetry Log can record for 90 minutes.
1) From within the SETTING menu, scroll UP or DOWN to highlight LOG STEP 00.1.
2) Press the ENTER key, then scroll UP or DOWN to change the Telemetry Log Step value.
Programming a lower Telemetry Log Step value results in narrower, higher resolution
readings, but for a shorter period of time. Programming a higher Telemetry Log Step
value results in broader, lower resolution readings, but for a longer period of time.
TELEMETRY LOG STEP setting range is 00.1 to 45.9. The default setting is 00.1.

11.VR ADJUST (VARIABLE RATE ADJUSTMENT)
SYSTEM
The Variable Rate Adjustment function allows you to calibrate the operation of the Steering Wheel, Throttle Trigger and Auxiliary
Lever End Points and Neutral positions. Over time, it's possible that the End Points and/or Neutral positions of these controls
may change slightly or you may purposely limit the travel of the Steering Wheel to suit the best feel of the Steering Wheel and
your driving style. Being able to calibrate these controls ensures precise operation at all times and in all conditions.
We recommend using the Variable Rate Adjustment function as part of a periodic maintenance schedule or after adjusting
the Steering Wheel travel as described in the Steering Wheel Travel Adjustment section on page 13.
IMPORTANT: After using the Variable Rate Adjustment function, you should double-check the End Point Adjustments of each
saved Model. If the End Points have moved, they will need to be readjusted using the End Point Adjustment function.
The steps required to calibrate the operation of the Steering Wheel, Throttle Trigger and Auxiliary Lever are the same. The
example shown in this section details calibrating the Throttle Trigger.

TELEMETRY CONNECTIONS AND MOUNTING
REFERENCE
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 M12 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 section on
pages 14 and 15. For more information about choosing Telemetry options, see the Telemetry Display Options section on
pages 63 through 68.
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.
REFERENCE
Overview:
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.

TELEMETRY CONNECTIONS AND MOUNTING
IMPORTANT: If the Sensor Wires are not long enough for your specific application, you can carefully splice in extra wire of
similar gauge to extend the Sensor Wires to the desired length. Make sure to solder the splices securely together and protect
the splices using heat-shrink tubing.
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.
Spur Gear or Other Rotating Part
Input Plug
Sensor Pickup
~1mm
Reflective Decal
RPM Sensor
Angled Bracket
Sensor Pickup
Sensor Pickup
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.
IMPORTANT: 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.
IMPORTANT: 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 Display Options section on pages 63 through 68.
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.
