This is an optional Traxxas "Short" Temperature & Voltage Sensor. Temperature data is critical to monitoring performance, gauging the effects of changes, and preventing overheating. The Temperature Sensor features a precision thermistor and is installed on the motor or engine to continually monitor temperature as you drive. The Temperature Sensor can also be fitted to a speed control, battery, or exhaust pipe to monitor its temperature.
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.
