Standard telemetry sensors use your model's gear ratio and tire size to calculate its speed based on RPM. Using the Telemetry Expander and the GPS speed module, vehicle speed can be captured and displaced easily and more accurately. The Traxxas GPS speed module uses global positioning satellites to deliver precise, real-time speed information via the Traxxas Link App on your TQi Radio System with Traxxas Link Wireless Module or Docking Base.
The GPS speed module easily installs inside the waterproof Telemetry Expander Module (#6550, sold separately) and is recognized automatically by the Traxxas Link App. No other programming or setup is required! Once the GPS module is installed in the Telemetry Expander, the speedometer reverts to the GPS speed instead of estimating the MPH based on gearing and motor RPM. Nothing has to be reset to start reporting and recording speed; just select the gauge that you want to be displayed and you're all set!
