I think JohnVH hit the nail on the head about the throttle/pitch curves but the one thing I've never seen mentioned is the fact that unless you have the throttle trim all the way up you're not getting all the blade pitch available. Throttle trim has a major impact on pitch at high throttle settings. I'm new to heli's so I'm not sure how "normal" this is, but the e-flite radio is set up this way. Seems to me to be a good excuse to go separates and use my jr6102. Tom
