While cooling the motor with the fan, the aluminum brace tied in with the aluminum front bulkhead, also aid in dissipating heat. Comes complete with a JST plug. Can be used with 95% of bodies without issue.
Excellent product from 3 Racing. The heatsink replaces the D3 CS's two support post for the front bulkhead. A very cleaver design. Also don't worry about the bear wire end you see in this picture. A pair of male/female connectors are there.
