Motor heat sink

Tamiya TT-02B MS · 84418

This adds an aluminum heat sink to the motor, giving heat another path into the surrounding air. It is a cooling option for a compatible motor, while the original motor mount's pinion limits and the available clearance still apply.

Installation notes

  • Fit the 54571 heat sink with the TT-02B MS motor and body clearance checked.
  • With the stock motor mount, keep pinion selection within the manual's 16-19T range. The heat sink does not allow a 20T or larger pinion on that mount.
  • The motor is selected separately for the chassis kit; check the fitted motor-can size before assembly.
