Traxxas TQi Telemetry Expander 2.0 TRX6550X

Overview

The Traxxas TQi Telemetry Expander 2.0 (TRX6550X) represents a game-changing advancement in RC car monitoring and data logging technology for enthusiasts across the UK. This sophisticated telemetry device transforms your RC driving experience by allowing you to monitor and record real-time data from your vehicle whilst you drive, giving you unprecedented insight into your model's performance. Whether you're piloting a brushless RC monster truck, a high-speed racing buggy, or any other TQi-equipped Traxxas vehicle, this expandable telemetry system provides professional-level tuning and diagnostic capabilities that were previously only available to top competition drivers.

Designed for RC enthusiasts who demand more from their hobby, the Telemetry Expander 2.0 connects seamlessly with the Traxxas TQi radio system and works in conjunction with the free Traxxas Link app available on Apple iOS and Android devices. The system's advanced communication bus technology allows you to expand your monitoring capabilities well beyond basic vehicle telemetry, incorporating additional sensors for temperature, voltage, and GPS speed tracking. This makes the Telemetry Expander 2.0 an essential accessory for serious RC hobbyists in the UK who want to optimise their vehicles, troubleshoot performance issues, and share their driving data with fellow enthusiasts.

Installation is straightforward and requires no complicated modifications to your existing RC setup. The water-sealed design ensures your telemetry equipment remains protected from the elements, whether you're bashing through muddy terrain, splashing through water crossings, or racing at high speeds on tarmac. This is a must-have upgrade for any TQi-equipped ready-to-run RC car, truck, or buggy.

Technical Performance

The Telemetry Expander 2.0 is engineered to work with the complete Traxxas TQi ecosystem, requiring a TQi transmitter with the 6511 Bluetooth Wireless Module installed to function. The device utilises advanced communication bus architecture that allows connection to TSM receivers, High-Voltage Power Amplifiers (part #6590), or directly to VXL-6S and VXL-8S electronic speed controls through optional data cables including the #6566 Data Link Cable for X-Maxx, E-Revo, and Unlimited Desert Racer models, or the #6565 cable for vehicles equipped with the #6590 High Voltage power amplifier. The expander accepts three standard Traxxas sensors plus up to six additional auto-detectable sensors, with three sensor types currently available: voltage sensors (part #6527), temperature sensors (part #6526), and GPS modules. The system's waterproof construction protects against water ingress and moisture damage, making it suitable for all-weather RC car UK driving conditions. The telemetry data is transmitted wirelessly to your mobile device via the Traxxas Link Wireless Module, providing real-time monitoring with a user-friendly interface that displays all monitored parameters in an easy-to-read format. Integration with the Traxxas Link app means you benefit from automatic sensor recognition, eliminating configuration headaches and allowing you to focus on driving and optimising your brushless RC truck, buggy, monster truck, or other vehicle.

Frequently Asked Questions

• Is the Traxxas TQi Telemetry Expander 2.0 compatible with all Traxxas RC models? — The Telemetry Expander 2.0 is compatible with any Traxxas vehicle equipped with the TQi radio system. Models using the older TQi radio generation with the #6533 receiver can connect directly, whilst X-Maxx, E-Revo, and Unlimited Desert Racer models with VXL-6S or VXL-8S ESCs require the optional #6566 Data Link Cable. Vehicles equipped with the #6590 High Voltage Power Amplifier require the #6565 Data Link Cable. Vehicle-specific mounting kits are available for popular models including the Rustler, Bandit, Slash, Stampede, Rally, Jato, XO-1, Summit, Revo, Slayer, Spartan, M41, and TRX-4.
• What's the difference between the Telemetry Expander 2.0 and the original Telemetry Expander? — The new GPS Module 2.0 (#6551X) and Telemetry Expander 2.0 (#6550X) replace the original models and are not compatible with the older versions. The 2.0 versions offer improved reliability, enhanced water sealing, and better integration with the latest Traxxas Link app versions.
• Do I need a GPS module to use the Telemetry Expander 2.0? — No, the Telemetry Expander 2.0 functions independently and provides valuable telemetry data without a GPS module.
