The TRX-4M^® Brushless 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 Trail^® rig. 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 Scale^® light kits and works 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 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.

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 with no modifications required. The system works with all existing TRX-4M parts and accessories including Pro Scale LED light kits and high/low two-speed transmissions. To get the most performance from your truck, consider the upgrades listed below for improved compatibility and toughness.

Recommended Upgrades

Metal Axle Gears
Give your TRX-4M the ultimate drivetrain upgrade with these front and rear metal axle gears. Metal axle gears increase strength and durability to handle increased brushless power.

Heavy Duty Center Driveshafts
Upgrade your center driveshafts with all-metal heavy-duty telescoping driveshafts for maximum strength and durability. The tough steel drive hubs key into brightly anodized 6061-T6 aluminum shafts for unbeatable strength and style.

High/Low 2-Speed Transmission
Take advantage of increased brushless torque and speed with the High/Low 2-speed transmission. The manually selectable unit adds a low gear option for incredible rock-crawling torque, while keeping the standard high gear ratio for high-speed brushless driving and wheelie-popping fun.

Portal Axle Kit
Portal axles increase TRX-4M’s all-terrain capability by raising the vehicle at the axles. Center ground clearance increases by over 10 mm and the track widens by 9 mm for a whole new level of 1/18 scale crawling capability.
