This F103GT-09A/LB motor heatsink is made to fit Tamiya F103, F103GT and F103RM chassis and increases the external surface area to pull heat away from the motor during track sessions and practice runs.
The component comes with a light blue anodized-style finish and is supplied as a direct-fit accessory for the listed Tamiya chassis. Fit it where additional cooling is useful to keep motor temperatures more consistent on longer or repeated runs.
Installation and tuning notes: the heatsink mounts to the motor housing to boost heat transfer; after fitting check motor and ESC temperatures and adjust run length or gearing to suit any change in thermal behaviour.
