What this heatsink brings to your setup

Made to suit the Tamiya F103, F103GT, and F103RM chassis, the heatsink keeps weight to a minimum while increasing surface area via precision fins. That promotes better air contact and more efficient heat transfer from the motor can. Whether tuning for practice or racing, this upgrade helps preserve motor life and maintain power delivery.
