This is a brushed motor heatsink designed to clamp onto the outer can of a 390-size motor used in IMEX Shogun, Ninja, and Katana platforms. It helps improve heat dissipation by increasing the surface area exposed to airflow, allowing the motor to run cooler under sustained load. The heatsink works by conducting heat away from the motor casing into aluminum fins, where it is then dispersed into the surrounding air during driving. It is typically used in combination with the stock motor setup to improve durability during extended runs, higher gearing, or warmer conditions. Installation is done by pressing or clamping it directly onto the motor body for a snug thermal contact fit.
