The TRX-4MBrushless Power System gives you up to 50% more speed, more crawling torque, and greater precision than brushed power systems. Rip wheelies in your monster truck or navigate a technical crawling course in your custom High Trailrig. The new TRX-4M Brushless Power System gives you the best of both worlds!

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

The new brushless ECM offers all the same great features as the standard ECM, but with even more compatibility. The integrated lighting control module and receiver maintain all existing functionality with existing Pro Scalelight kits and works with both TQ and TQi transmitters. New field-oriented control (FOC) programming allows the ESC to monitor the motors position for ultra-precise control. The brushless ECM offers two servo output ports and two Pro Scale lighting ports and even uses the same battery connections and mounting bosses for true plug-and-play capability.
