Anybody out there using castle ice 50 esc's on their quad?  If so what were your castle link settings?    I put together a large 6s quad (using extra airplane parts) and I am having a hard time getting it tuned up.  Cant get the thing to stop wobbling in the air.  PID adjustment is very sensitive, so much so that when I do get the wobble out I have no control authority. Thanx
