Ps did you check the compensation direction. Was the heli uncontrollable or did it tilt before the crash ?

The heli was very stable for the first tank hovering... just little wobble on the tail but I fix the gain and was ok...
It's hard to say why it tilt on the second tank around 1650 rpm before hovering! since it happen in a fraction of a second really!! I will go back on the field this weekend and I try again...

Strange, I did my re-maiden today with the cgy750 used 34 avcs for the tail , a little to low and 50 ail gain avcs and 50 ele avcs gain. Had a wobble around 1700rpm but at 1850 very stable. Now i have to tune the gains adjust govenor etc but it is looking very good at this moment. Hopefully tomorrow when the weather is ok i will try some more flights.

I am flying with avcs of 60- tail, 54, aileron and 64 elevator and a head speed of 1950 in idle up two. It is working very well for me. I am also running and I gain of 60 on aileron and elevator.

What does i gain doing ? I did not change/or looked at that parameter so its still standard

i gain can be thought of your gain for inverted flight. It helps with tracking and rolling maneuvers while inverted. If you look over in the CGY 750 forum there are a few threads about adjusting the i gain up from stock settings. Around 60% seems to be the general consensus for i gain. That's what I have the i gain set on both of my units. Seems to work well.
