SPEKTRUM TELEMETRY

RPM/Speed Sensor (Nitro)

An infrared sensor is provided to record rpm values that can be

converted by the handheld unit to actual speed in mph. 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 gear or 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 2mm screw, attach the sensor to the mount as shown.
