Telemetry is the ability to gather performance data from your vehicle remotely. When you equip a Traxxas model with the required telemetry accessories, motor or engine RPM, temperature, speed, and battery voltage are visible live, right from the screen of the Apple iPhone or iPod touch (2nd generation or later) that you install in the Traxxas TQi transmitter with Docking Base. This data is displayed on the Traxxas Link dashboard and can be recorded and played back later.

Traxxas makes telemetry easy. Just select your model and click the Telemetry tab to see which sensors are required for your model, and the data they will collect. Installation is simple. Telemetry-ready accessories simply replace stock parts for fast and accurate sensor and magnet setup. No taping, guessing, gluing, or modifying required!


Real Time Telemetry

The Traxxas Link App collects and records real-time telemetry data as you drive. The Traxxas Link App dashboard shows you speed, battery voltage, RPM, and temperature. The application automatically detects and recognizes Traxxas Link sensors for easy set up and configuration. The dashboard is fully customizable with either dial or digital readout gauges. Up to nine gauges can be displayed at once. Set threshold warnings and log maximums, minimums, or averages. Use the recording function to document your dashboard view, with sound, so that you can keep your eyes on your driving and not miss a single apex. If you forget to record, simply touch Instant Replay anytime to capture the previous minute of fun and unexpected triumphs. The recordings can be named and saved to compare, review, and share with friends.



RPM stands for Revolutions Per Minute. To collect this critical data, 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. Speed is displayed on the Traxxas Link App's dashboard speedometer.


Temperature data is critical to monitoring engine performance, gauging the effects of gearing changes on electric models, 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.


Voltage measurement isn't just for electric cars; the voltage of a nitro vehicle's on-board battery is also critical. An accessory voltage/temperature sensor is available to measure receiver battery pack voltage on nitro vehicles. To monitor the voltage of your electric vehicle's battery, the Power Tap Connector is installed over the speed control's Traxxas High-Current Connector. Battery voltage is measured and displayed as you drive, making it easy to see voltage drop under acceleration and monitor battery performance.
