Iam new to cp helicopters I got one thing I don't understand. My question I have is when you are centering servos you have the radio in idle up /sound mode and the left stick centered and swash level. But when I flip the idle up/stunt mode off to go to normal my swash plate and servos all get out of wack. I don't do 3D I just like normal flying. Can any one offer me any suggestion. Thanks
