The Tamiya M03M Motor Heatsink by 3Racing, model M03M-21/SI, is specified to enhance heat management on the Tamiya M03M chassis. It provides a larger exposed surface area to assist steady thermal dissipation during extended high-load runs.
Manufactured to consistent quality standards, this heatsink aids in moving heat away from the motor housing to reduce peak temperatures. Improved dissipation helps maintain torque and throttle response under repeated demanding cycles.
Developed for compatibility with the Tamiya M03M mounting geometry, the heatsink installs without chassis modification and uses standard RC fasteners. The direct fit keeps motor alignment intact while adding cooling capability.
