Key Features
- Centre Differential Telemetry Integration — This magnet holder mounts directly onto your centre differential and works in conjunction with an RPM sensor to capture real-time rotational speed data, which is essential for drivers who want to monitor drivetrain performance and optimise gear ratios and differential settings for maximum efficiency.
- Real-Time RPM and Speed Data — By securing the trigger magnet to the spur gear mechanism, this holder enables live telemetry feedback through the TQi radio system, allowing you to see exactly how your RC car is performing during each run without needing to stop and analyse data manually.
- Traxxas Link Wireless Module Compatible — This telemetry trigger magnet holder works seamlessly with the Traxxas Link Wireless Module (sold separately) and the TQi transmitter platform, integrating into Traxxas's comprehensive telemetry ecosystem for serious data logging and performance analysis.
- Free Mobile App Integration — The complementary Traxxas Link app for iOS and Android devices allows you to visualise and store your telemetry data on your smartphone, making it easy to track performance improvements over time and share results with fellow RC enthusiasts.
- Precision Magnet Assembly — Includes a high-quality 5x2mm magnet (1 piece) specifically calibrated for reliable sensor detection, ensuring consistent and accurate RPM readings during all driving conditions and speeds.
- Secure Fastening Hardware — The package includes three 3x8mm BCS screws (3 pieces) providing robust, vibration-resistant attachment to your centre differential housing, maintaining alignment and magnet positioning even during aggressive off-road or racing conditions.
- Scale-Appropriate Design — Purpose-built specifically for centre differential applications on 1/10 and 1/16 scale RC models, this telemetry holder is engineered to fit perfectly within the confined space of your differential assembly without interfering with other components.
Technical Performance
The Traxxas Telemetry trigger magnet holder represents sophisticated engineering designed for drivers who need accurate performance metrics. This component functions as the bridge between your RC car's mechanical drivetrain and your radio system's telemetry capabilities. The magnet holder secures a 5x2mm rare-earth magnet that rotates with the spur gear, passing by an external RPM sensor with each revolution. This magnetic pulse is transmitted wirelessly to your TQi radio system equipped with the 6511 Traxxas Link Wireless Module, creating a seamless data stream to your mobile device. The precision-engineered mounting points ensure the magnet maintains consistent clearance from the sensor for reliable detection across the entire RPM range of your vehicle. Construction utilises Traxxas-quality materials and manufacturing standards, with three 3x8mm BCS (Ball Cup Screws) providing vibration-resistant fastening that maintains positional accuracy even under the most demanding driving conditions. The compact design is optimised for centre differential housings, ensuring it doesn't create drag or interference with other drivetrain components. Whether you're running a brushless or brushed motor system, this telemetry solution provides the same reliable data acquisition that professional RC racers depend on for performance tuning and competitive analysis.

Frequently Asked Questions
- What vehicles is the Traxxas telemetry trigger magnet holder compatible with? — This centre differential telemetry magnet holder is specifically designed for compatible Traxxas models including the TRX74276-4-GRN Traxxas Ford Fiesta ST Rally VXL (Green) and the TRX74154-4-RED Traxxas Ford Fiesta ST Rally BL-2S Rally Car (Red). Before purchasing, verify that your specific RC model has a centre differential and is listed as compatible with the TRX6539 telemetry system.
- Do I need any additional components to use this telemetry magnet holder? — Yes, this magnet holder is only one piece of the complete telemetry system. To capture and display real-time data, you will need a separate RPM sensor, a TQi radio transmitter with the Traxxas Link Wireless Module (model 6511), and a compatible mobile device running the free Traxxas Link app. Without these components, the magnet holder will not provide any telemetry functionality.
- How does the magnet holder improve my RC driving experience? — Once fully set up with all required telemetry components, this magnet holder enables you to monitor real-time RPM and speed data directly on your mobile device through the Traxxas Link app. This allows you to identify performance issues, optimise your differential setup, verify motor KV ratings and ESC performance, and track improvements over multiple driving sessions, making it invaluable for competitive racers and serious performance enthusiasts.
- Is installation difficult or do I need special tools? — Installation is straightforward for anyone with basic mechanical knowledge of RC cars. You simply mount the magnet holder onto your centre differential using the three included 3x8mm BCS screws. No specialised tools are required beyond a standard hex key or screwdriver. The magnet holder is designed for a secure fit that withstands vibration from aggressive driving.
- Can I use this telemetry system with brushless and brushed motors? — Yes, the telemetry trigger magnet holder is motor-agnostic and works with any compatible centre differential regardless of whether your vehicle is powered by a brushless or brushed motor system. The RPM data it captures reflects the actual drivetrain speed, making it valuable for both motor types.
- What makes Traxxas telemetry superior for RC cars in the UK? — Traxxas is a recognised leader in RC technology, and their telemetry system integrates seamlessly with their TQi radio platform and mobile app ecosystem. This provides UK RC enthusiasts with professional-grade performance monitoring that's typically reserved for expensive racing operations, now accessible to bashers, weekend racers, and serious competitors at an affordable price point.
