Traxxas TRX-4m Combo Brushless Waterproof ECM + 3350Kv Motor

NEW TRX-4M Brushless Power System

Boost the performance of your TRX-4M® with up to 50% more speed, more torque, and greater crawling precision. From ripping wheelies to technical crawling, the new TRX-4M Brushless Power System gives you the best of both worlds!

Brushless Outrunner Motor

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.

Brushless ECM

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.

Recommended Upgrades

• Traxxas 9779 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.
• Traxxas 9751 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.
• Traxxas 9891 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.
• Traxxas 9843R 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.
