Motor Heatsink 4685 (ARA390296)

This aluminum motor heatsink is designed for 46mm-diameter motors, helping keep them cool during high-intensity runs. The kit includes a heatsink and a clip for secure mounting.

Made from lightweight aluminum, it uses a multi-fin design to maximize heat dissipation. The black anodized finish with an etched ARRMA logo gives a clean, durable look, and a flat area on the heatsink accommodates a 50mm fan for added cooling on 46mm motors.
