Harebear I'm not sure if it will cause premature wear. It does make control more difficult though.

Lablover what your going through is normal. The tail rotor thrust causes the heli to drift left then over-compensating with right cyclic will cause the heli to roll right. Many of us went through this. Just take it slow, you'll get it. Unfortunately the FASST system is incompatable with the 3-in-1 so it can't be used.
