This set includes the Front Sink and Rear Mount for your motor.
This motor mount system is not only sexy but functional as well. The bright silver finish is quite beautiful, and if you happen to scratch or ding it, its the same color throughout.
It is machined from aluminum alloy which allows it to transfer heat away from the motor more efficiently than other materials.
It is also very light, weighing in at only 2.99 Grams. For comparison the Radio Shack cast motor heat sink that comes with the Stage 2 Motors Set weighs in at a whopping 11.86 Grams.
