Overview
Cool your 540 or 550-size motor with classic Tamiya-blue style with the Hot Racing Universal Clip-On Aluminum Top-Fan Heat Sink. The aluminum heat sink clips onto the motor for direct heat transfer, while the side-mounted fan with offset plate provides forced airflow over the heat sink fins for maximum cooling performance.
The clean Tamiya-blue finish makes this heat sink a perfect match for vintage and classic-style RC builds where stock-look aesthetics matter — without sacrificing modern cooling performance.
