So I picked up a 6S Typhon last week . First thing I did was order a Yeah Racing Duel Fan heatsink of the motor. I had seen others had suggested the YR for it. Went to put the heatsink on and found that the heatsink when tightened down was still a little loose on the motor. I had ordered the 40mm heatsink. So to get the heatsink to tighten down on the motor I wrapped a couple of layers of aluminum tape around the motor. Looking for opinions on this fix . Good or bad.
