I noticed on your helis you have a linear curve for throttle most people have a V curve. So does that mean you're able to hover and do forward flights only?
Why do you have -5 for the hold mode? Are you cutting the throttle with hold mode?
I still don't understand why most throttle curves are a V, like 100%,75%,50%,75%,100% in 3d mode. If I move the stick bottom to top does that cause the heli to flip?
