heat sink on brushless motor ?

hi,

maybe it sounds stupid but can you put a heat sink on a brushless motor? cuz i never saw a heat sink on a brushless motor

You can it its inrunner brushless motor. But since most use the outrunner motor on helicopters and because the whole outside casing of the outrunner motor spins very fast, you should not use a heat sink. Not only it will throw off the balance it will probably fly off. This is my opinion.
