Tamiya M03M Heatsink 3Racing M03M-21/SI Compact Cooler  [M03M-21/SI]

Cooling upgrade for the Tamiya M03M

The Tamiya M03M Motor Heatsink by 3Racing, model M03M-21/SI, is made to improve thermal control on the Tamiya M03M platform. It reduces heat buildup so the motor keeps performing consistently through long practice or race sessions.

Efficient thermal transfer

Using durable materials, this heatsink increases the area available for heat to escape from the motor. That improved heat transfer helps avoid thermal cutback and keeps components running cooler in demanding conditions.

Designed for direct fit

Specifically matched to the Tamiya M03M, the heatsink fits cleanly into the existing layout and installs with standard hobby tools. The fitment keeps the setup tidy while adding functional cooling benefits.
