The GPM GP10 alloy motor heat sink is a precision component for 1:2 and 1:10 on-road models that optimises thermal dissipation. Manufactured to tight tolerances, the alloy fins provide a consistent surface area that accelerates heat transfer from the motor housing, reducing temperature rise under sustained load. The compact, engineered profile allows straightforward integration with standard on-road motor mounts and supports improved thermal reliability during competitive use.
