This is an RC-scale alloy heat sink plate designed to attach to the gearbox housing of Tamiya Tracktor truck models, supplied as 2pcs. The plate uses a finned profile to increase surface area and promote passive heat dispersion from the gearbox during extended indoor or outdoor running sessions.
The part is intended as an accessory for model-level thermal management, not as a replacement for internal gearbox maintenance. It mounts to existing gearbox fixings and works alongside regular upkeep such as gear mesh checks and bearing inspection. Material is aluminum alloy which balances thermal conductivity and weight for scale truck applications.
Practical tuning role: adding the finned plate can help stabilise gearbox temperature under continuous operation, which may reduce the rate of thermal-related performance drift in electric motors and ESC systems on scale truck runs. It is a passive accessory, requiring no wiring or modification to electronics.
Use this GPM alloy heat sink plate when you need a simple, bolt-on option to improve gearbox heat dispersion on a Tamiya Tracktor Scania R620 model, keeping the upgrade aligned with standard maintenance practices.
