RE: 1/2 or 3/4 stick hovering?
My pitch and throttle curves are close but not the same above 1/2 throttle. My Raptor 50 drops just a touch when I flip into idle up. The RPM goes up and the pitch goes down a little, but in the end the curves are set the way I like them and that's all that really matters.
If you like the normal curves you have leave them. You may choose to change them later, I did. Mine were way off at first now they are close.
