i agree could be nothing like patrick said but what circuit is affected when the fan dead shorts? it will do something somewhere in the esc. whatever, easiest fix ever, 1.5" shrink tube, and a little patience. small task considering the time and effort spent on the rest of the vehicle. this pinch is obviously happening at the factory as the esc is assembled. the only way they would know is to open it back up after bench testing and have a look see. but then again it works why open it? like i said before when i got my v3 out of the box i peeled the sticker off so i could mount it and opened it (past mmm's had pinched fan wires too) to check the fan wires, both were showing copper.
