Tamiya F103 / F103GT / F103RM Aluminum Motor Heatsink by 3Racing F103GT-09A/LB  [F103GT-09A/LB]

Light blue aluminum motor heatsink

This 3Racing F103GT-09A/LB is an aluminum motor heatsink produced for Tamiya F103, F103GT and F103RM chassis. It provides an external cooling surface that helps move heat away from the motor during on-track runs and practice sessions.

The part is finished in a light blue anodized-style coating and is presented as a direct accessory for the listed Tamiya chassis. Use it where extra cooling is needed to sustain consistent motor temperature during extended driving or repeated runs.

Installation and tuning role: the heatsink is intended to be fitted to the motor housing to increase surface area for heat transfer; when tuning, observe motor and ESC temps after fitting to evaluate any change in thermal behaviour and adjust run length or gearing accordingly.
