The 3RACING 3RAC-MHS008/RE is a compact cooling upgrade for 540 motors, shaped to channel air across the motor can and reduce peak temperatures encountered during extended running.
The enlarged contact area and integrated fan work together to move heat away from the motor body, helping maintain steady output over repeated runs or long practice sessions.
This heat sink is targeted at hobbyists who need dependable cooling without complex installation, offering straightforward thermal management for everyday track use.
