Take your R/C experience to the next level by adding Telemetry to your model (locate your model in the Telemetry Finder). Combined with the Traxxas Link™ Wireless Module and the Traxxas Link App, Telemetry sensors communicate performance data, such as speed, RPM, temperature, and battery voltage, from your model to your Android, iPhone^®, iPad^®, or iPod touch^®. Not only does Telemetry let you monitor and record performance data, it also gives you the ability to remotely make adjustments and tune your model on-the-fly.

Whether you're trying to shave a second off your lap time or breaking a speed record, Traxxas makes Telemetry fun and easy to use. Sensors can be installed quickly and easily. The Traxxas Link App automatically recognizes the sensors, eliminating any guesswork (Note: Some models feature factory-installed Telemetry sensors).

To experience all the features of the TQi transmitter with the Traxxas Link Wireless Module and Traxxas Link application,
you will need a mobile device running Android 4.4+ or Apple iOS 4.3+. Please see below for more details.

Real Time Telemetry

The Traxxas Link App collects and records real-time telemetry data as you drive, while at the same time, allows you or a friend to make on-the-fly adjustments. 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, or use a single digital readout gauge for monitoring all-out speed. 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 the action. 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.

TQi Telemetry Expander and TQi GPS Speed Module
The Traxxas TQi Telemetry Expander (#6550) broadens the possibilities of the telemetry system. You can monitor and record real-time telemetry data just as before, but the Telemetry Expander is able to accept up to 6 plug and play sensors for monitoring and recording temperature and voltage. Using the Expander, you can monitor the temperature of the motor, speed control, and battery/batteries while receiving voltage data on your electric model. With nitro models you can monitor how tuning affects cooling head, header pipe, and exhaust pipe temperatures. To install the Telemetry Expander you will need the appropriate Telemetry Expander Mount for your vehicle. Another advantage of the Telemetry Expander is the ability to use the TQi GPS Speed Telemetry Module.

The TQi GPS Speed Telemetry Module (#6551), when installed in the Telemetry Expander, uses global satellite positioning to track and wirelessly send accurate, real-time information about the speed of your Traxxas model back to the Traxxas Link App. There's no guesswork or inputting gear ratios and tire size. Plug in the GPS Module to the Expander, the Traxxas Link app automatically recognizes it, and you're ready to see how fast your model is moving.

Device Requirements
Traxxas Link is designed for use with Android 4.4 and up or iOS 4.3 and later. Traxxas Link is compatible with Android equipped devices, iPhone (4S, 5, 5C, 5S), iPod touch (5th generation and later versions), iPad (3rd generation and later versions), or iPad mini. For full functionality, Traxxas Link requires a Traxxas TQi transmitter with Traxxas Link Wireless Module and a TQi receiver installed in the model. Telemetry functions require Traxxas telemetry sensors to be installed on your model.

Traxxas Link Wireless Module (#6511) included with some Traxxas models (also sold separately).
