"I have been testing the CGY 750 in a Compass 6HV, I used the programing 'elev-ail' to correct back flips. As the 750 flies more like a FB model, I needed to correct my flips for gyroscopic precession. I used approx. 8% right Ail in back Elev flips, to correct a left rolling tendency.
I like the easy set-up, the connected feel on cyclic, the piro rate is very consistent, but it's lacking for me in piro compensation. The flight path is not very stable with multiple piros, also when hovering. It takes a lot more correcting to direct the flight path."
