Telemetry signal strength and receiver battery voltage
is built into the receiver's telemetry and no further
attachment of sensors is necessary. Telemetry signal
strength and receiver battery voltage will be displayed
when the transmitter and receiver are both turned on.
Note: The voltage displayed is the receiver
voltage. This is especially useful for nitro cars
in alerting you to change your receiver pack
before your vehicle goes into failsafe due to
low battery pack voltage.
Note: The receiver battery must be above 3.5
volts for proper telemetry operation.

rpM/speed sensor (nITro)
An infrared sensor is provided to record rpm values that
can be converted by the transmitter unit to actual speed
in mph or km/h. The sensor emits an infrared light and a
receptor records the reflection vs. the absorption of light.
It is necessary to place a reflective or light absorbing
decal (provided) on the flywheel to allow the sensor to
record rpm. Mounting hardware is provided for easy
installation.
RPM/Speed Sensor Installation (Nitro)
• Choose the correct nitro mount for your engine. Two
mounts are provided: one for .12–.18 engines and
one for .21–.28 engines.
• Using the 2mm screws, attach the sensor to the
mount as shown.
