The F103GT-09A/LB heatsink is designed to suit Tamiya F103, F103GT and F103RM chassis, increasing the external surface area to help dissipate motor heat during circuit sessions and practice laps.
Presented in a light blue anodized-style finish, the part is offered as a direct accessory for the listed Tamiya models. Install it where extra cooling is needed to maintain consistent motor temperatures over repeated runs.
Fitment and tuning guidance: mount to the motor housing to expand the heat transfer area; monitor motor and ESC temperatures after installation and adjust run durations or gearing to match changes in thermal behaviour.
