Ok from what i can say, my heli didnt kiss the floor before.

So bent main shaft and tail rotor shaft i think is out.

Checked the frame, no crack.

Main rotor blade and tail all using Vblades and it was very well balance when i first bought it. Till today, the blade dont have any small chip off.

Fan out of balance, fan not dailed right and engine i dont really know how to do.

Can u tell me what is your needle setting on your OS91SZ + pump ? ( if you are using OS91 SZ + pump )

Are you using muffler pressure ? ( i am not using muffler pressure )
