Traxxas TQi Telemetry GPS Module 2.0 TRX6551X

Overview

The Traxxas TQi Telemetry GPS Module 2.0 (TRX6551X) represents the pinnacle of precision speed monitoring technology for modern RC enthusiasts in the UK. This advanced telemetry accessory integrates seamlessly with your Traxxas TQi radio system, delivering real-time, GPS-based speed data that eliminates the inaccuracies plaguing traditional speed calculations. Whether you're a competitive racer pushing your brushless RC car to its limits, a weekend basher exploring off-road terrain, or an enthusiast looking to unlock deeper insights into your vehicle's performance, this GPS module transforms how you monitor and understand your RC experience.

The fundamental problem with conventional telemetry speed sensors is their reliance on mathematical calculations derived from your vehicle's gear ratio, tyre size, and motor RPM. While this approach works reasonably well on hard, grippy surfaces, it falls apart the moment your RC car hits loose terrain. Wheelspin on sand, gravel, or muddy ground causes these calculated speeds to become wildly inaccurate, frustrating drivers who want genuine performance data. The Traxxas GPS Module 2.0 solves this problem by bypassing mathematics entirely and instead using real-world positioning data from both GPS and GLONASS satellite networks to calculate your vehicle's actual speed with precision accuracy.

This is an essential upgrade for any serious RC car enthusiast in the UK who demands accuracy in performance monitoring. The module works exclusively with the Traxxas TQi radio system and requires the Telemetry Expander 2.0 (sold separately), creating a plug-and-play ecosystem that automatically configures itself with zero programming required. Installation is straightforward, the system is completely waterproof when properly installed, and the real-time speed data displays directly in the Traxxas Link App on your compatible iOS or Android mobile device.

Key Features

• Dual-Satellite GPS and GLONASS Positioning — The module utilises both GPS and GLONASS global positioning systems simultaneously, providing superior satellite coverage and dramatically improving location accuracy in challenging environments such as urban areas with tall buildings, dense woodland, or areas with poor GPS signal. This redundant system ensures consistent, reliable speed calculations in virtually any terrain where you choose to drive your RC model.
• Real-Time Accurate Speed Data — Unlike standard telemetry sensors that estimate speed based on gear ratios and tyre sizes, this GPS module measures your vehicle's actual ground speed in real time. The system is completely unaffected by wheelspin, slip, or terrain conditions, delivering honest speed readings whether you're driving on tarmac, loose gravel, sand, or mud.
• Automatic Recognition and Zero Configuration — The Traxxas Link App automatically detects and configures the GPS Module 2.0 with absolutely no manual programming, setup screens, or technical configuration required. Simply install the module, pair your TQi system, and start receiving accurate speed data immediately—the system handles everything intelligently in the background.
• Waterproof Installation — When installed inside the waterproof Telemetry Expander 2.0 housing, the GPS module maintains full waterproof protection, making it suitable for challenging weather conditions, water crossings, and wet terrain without compromising performance or reliability. This weatherproof design ensures your telemetry system survives demanding RC adventures.
• Seamless TQi Integration — The module integrates perfectly with your existing TQi radio system and Traxxas Link Wireless Module, requiring no additional equipment, adapters, or workarounds. The entire system communicates wirelessly through your TQi receiver to display speed data directly in the Traxxas Link App on your smartphone or tablet.
• Speed Display Independence from Vehicle Setup — Speed readings are completely independent of your vehicle's gear ratio or tyre size, meaning you can experiment with different gearing and wheel configurations without affecting the accuracy of your speed data. This freedom is invaluable for tuning and optimisation.
• Compact, Easy Installation — The GPS Module 2.0 installs easily inside the waterproof Telemetry Expander Module 2.0 without requiring any complex modifications, soldering, or internal receiver box opening. This plug-and-play approach makes the upgrade accessible to RC enthusiasts of all skill levels.

Technical Performance

The Traxxas TQi Telemetry GPS Module 2.0 represents sophisticated engineering specifically optimised for RC vehicles equipped with TQi radio systems. The module utilises commercial-grade GPS and GLONASS receiver technology, the same satellite positioning systems trusted in marine navigation, aviation, and professional surveying applications. By combining data from two independent satellite networks, the system achieves positioning accuracy within metres, translating to speed calculations accurate to fractions of a mile per hour. The dual-satellite approach also provides superior performance in difficult signal environments, maintaining lock even when GPS alone would struggle. The module is engineered to fit neatly within the waterproof Telemetry Expander 2.0 housing, maintaining the watertight integrity of your telemetry installation. Communication with your TQi receiver occurs wirelessly via the Traxxas Link Wireless Module, eliminating the need for additional cables or data connections beyond the standard Telemetry Expander connection. The system processes position data continuously and calculates instantaneous speed in real time, updating the Traxxas Link App on your mobile device with minimal latency. This represents a dramatic upgrade over traditional RPM-based speed calculations, which remain mathematical estimates rather than actual measured speeds. The module is designed for use across the entire Traxxas TQi range, including high-performance vehicles like the X-Maxx, E-Revo, Unlimited Desert Racer, and other TQi-equipped models.
