This is an optional Traxxas "Long" RPM Sensor, and is intended for use with the Traxxas XO-1 1/7 Scale vehicle. To collect critical RPM data (Revolutions Per Minute), a "trigger magnet" is installed in the spur gear of electric models, or the flywheel of nitro vehicles. To offset the weight of the magnet, additional material is molded or cast into the opposite side of the spur gear or flywheel. To read the magnet, a hall effect sensor is installed in the gear cover (electric models) or installed on a support arm (nitro models). Each time the trigger magnet passes the RPM sensor, a revolution is counted. Revolutions per minute are displayed on the tachometer of the Traxxas Link dashboard. RPM is also the key to determining your model's speed. When you select your model in the Traxxas Link application, the app uses your model's transmission ratio and tire circumference to calculate its speed based on RPM, and the speed is displayed on the Traxxas Link App's dashboard speedometer.

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, or click here for details.

    How would i mount this on to a Traxxas slash 2wd transmission is there a mount for it ?
    Asked by Tony on 23rd January 2023

    There is a hole in the rear gear cover for the sensor to fit in to ( on the newer cars ) if you have an older car youwould need the new gear cover TRX3792

    You would also need the spur gear magnet mount TRX6538
