AX6520 AX6520 Sensor, RPM (long)/ 3x4mm BCS (2)

This is an optional Traxxas "Long" RPM Sensor, and is intended for use with a Traxxas vehicle using the Traxxas TQi Radio System with Docking Base. This sensor enables RPM and speed data to be displayed.

This is a replacement part for the Traxxas XO-1 1/7 Scale vehicle.

Note: In order to add telemetry to your Traxxas model, a TQi Radio System with Docking Base is required, as well as an iPhone or iPod with the Traxxas Link App installed. Most Traxxas kits require additional Traxxas chassis parts to install the telemetry system. Refer to your instruction manual for details.
