Traxxas gives you the power to unlock the full potential of the Traxxas TQi Radio System with Traxxas Link, the custom application that integrates your iPhone, iPad, or iPod touch with the TQi transmitter. Traxxas Link collects and records real-time telemetry data as you drive. When you equip your model with sensors, the Traxxas Link App dashboard comes to life showing you speed, battery voltage, RPM, and temperature. The application automatically detects and recognizes Traxxas Link sensors for easy set up and configuration.
