Had a tail boom break due to apparent metal fatigue today. Was doing repeated piro stops and noticed the tail rotor was at a 30 degree angle so I landed immediately and saw that it had cracked where the clamp holds the boom and was bent at a 15 degree angle. Didn't hit anything with the tail it just cracked in midair. If it had been a TT I'm pretty sure it would have crashed.

EDIT: I think it was the 10mm screws I was using to hold the boom supports, they had dug pits into the boom and it cracked right at this point. Going to switch back to 8mm screws. Also the tail belt is perfectly fine.
