Installation guidance and compatibility

To fit the Tamiya 53399 heat sink, push it onto the motor can until it seats. Check that there is sufficient clearance inside the motor bay and that the mount does not contact nearby parts. This item is not compatible with Tamiya TA03, M03, or FF02 chassis models.

Measure the available space in your motor bay before fitting. The heat sink adds diameter to the motor can and needs clearance from the chassis and gears.
Yes, it provides passive cooling that can reduce overheating during extended runs, making it useful for regular hobby and club sessions.
It complements fan cooling by adding surface area; combined cooling methods improve overall heat management.
Wipe clean after use to remove dust and debris, and inspect for damage; keeping the fins clean helps maintain thermal performance.
