Haha... well I take an allan key.. screw the screws in tight.. give them a little extra twist for good measure and fly my ***** off

Never had a problem with them backing out at all.
I got mine today. They were out of the 3.5 so I went with the 4. Looks pretty nice, but its big. Anybody ever painted one of these CF spinners or see a problem with that?
I have allens in mine as well, seems with an allen you could crank down pretty good....enough probably to crack the spinner in fact...might be the difference
