RE: Hanger 9 Ultimate.
First off, I agree with jmiracle. 50 paces is a good range. However, since you said it does it with the wings on, and not off, then I think that you might have a problem with your aileron extensions, or maybe a bad servo. Do you have all of your extentions twisted inside the wing? If they are straight, then they act like huge antennas. When they are twisted, they can't pick up a signal strong enough to cause problems.
