yeah i probably and going to buy a heat sink from my LHS , its going to be one of thse ones that you slide on that should work fine i think. but il probably end up putting a small computer fan on top of the heatsink. to keep it cool, i might do that to the esc as well if it starts getting hot. but dont know where to hook up the wires for the fan, maybe the reverse servo? but would it work if i use a Y harness and hook up the ESC with the stock throttle servo so i can use the mechanical brake instead of using the motor brake?
