The TRX-4M Brushless Power System provides up to 50% more speed, increased crawling torque, and enhanced precision compared to brushed power systems. Whether you're performing wheelies in your monster truck or navigating a challenging crawling course in your custom High Trail rig, the TRX-4M Brushless Power System delivers the best of both worlds.

Brushless outrunner motor
At the core of the system is the all-new 3350 Kv brushless outrunner motor. Designed for 2s LiPo power, this brushless motor offers exceptional torque and low-speed control to conquer any obstacle. In open conditions, the motor delivers high-rpm performance for significantly improved speed and wheelie-popping power. A black high gloss can with laser etching gives the motor a striking appearance.

Brushless ECM
The new brushless ECM retains all the great features of the standard ECM but offers even greater compatibility. The integrated lighting control module and receiver maintain full functionality with existing Pro Scale light kits and are compatible with both TQ and TQi transmitters. New field-oriented control (FOC) programming allows the ESC to monitor the motor’s position for ultra-precise control. The brushless ECM includes two servo output ports and two Pro Scale lighting ports, utilizing the same battery connections and mounting bosses for true plug-and-play capability.

Easy to install
The TRX-4M Brushless System is quick and easy to install. The ECM uses the same mounting bosses as the standard system, requiring no modifications. The system is compatible with all existing TRX-4M parts and accessories, including Pro Scale LED light kits and high/low two-speed transmissions. To maximize your truck's performance, consider the listed upgrades for improved compatibility and durability.
