Real-Time Speed

Standard telemetry sensors use your vehicle’s gear ratio and tire size to calculate speed based on RPM. This system works well for hard surfaces, but wheelspin on loose surfaces causes inaccurate speed readings. The Telemetry Expander 2.0 with the installed GPS Module 2.0 provides the most accurate speed data possible. The Traxxas GPS Module 2.0 uses both GPS and GLONASS global positioning to deliver precise, real-time speed information via the  on your TQi Radio System with .

The GPS Module 2.0 installs easily inside the waterproof Telemetry Expander Module 2.0 . The Traxxas Link App automatically recognizes the sensor with no other programming or setup required!

Nothing needs to be reset; just select your preferred gauge and start receiving accurate speed data through the .
