Traxxas TRX-4M Brushless ESC Power System

Traxxas TRX-4M Brushless ESC delivers up to 50% more top speed, stronger crawling torque, and much tighter low-speed control than a brushed setup. It’s built for drivers who want one power system that can rip wheelies in a monster truck and then tackle a technical High Trail rig, and it uses the same footprint and mounting points so the swap is straightforward.

Key Features

• Brushless outrunner motor — provides greater low-end torque and improved control at crawl speeds compared to conventional motor designs.
• 3350 Kv rating — tuned for lively throttle response and capable top-end RPMs for both bashing and trail work.
• Laser-etched motor can — durable identification and a clean, finished look for the motor housing.
• Includes 11-tooth pinion gear — supplied pinion for direct mating with standard TRX-4M drivetrains.
• Brushless ECM — keeps all the familiar ECM features and supports Pro Scale lighting controls for detailed rigs.
• Field Oriented Control (FOC) — offers more efficient motor management and smoother low-speed torque delivery.
• Compatible with 2S LiPo power — designed to work with common two-cell battery setups used in TRX-4M builds.
• Works with TQ and TQi transmitters — integrates with both radio platforms for flexible control options.
• Three drive modes — selectable modes tune the vehicle for different driving styles:
  • Sport: 100% forward, 100% brake, 100% reverse for full performance.
  • Trail: 100% forward, 100% brake, 100% reverse with Trail-tuned brake on neutral for smoother stops on inclines.
  • Crawl: 100% forward, 100% instant reverse response, 100% brake on neutral for precise low-speed maneuvers.
• Same footprint and mounting points — replaces the stock ECM without changing your chassis layout.
• True plug-and-play compatibility — drop-in installation gets you back on the trail faster with minimal setup.

Why Choose This Product

The Traxxas TRX-4M Brushless ESC Power System is a straightforward upgrade for TRX-4M-based builds, delivering both crawl-friendly control and usable extra speed for bashing. It’s well suited to hobbyists who want a single, versatile powertrain that installs easily and responds predictably across a wide range of driving conditions.
