I've been flying my TufFlight Predator a lot recently in hopes of getting it ready to enter a combat event... or at least try combat with some of the guys here. One of the things that I have noticed in the trimming process is that the neutral trim condition for full throttle, level flight appears to change dramatically in a high-speed dive. If left alone, as the airspeed builds up, the Predator has a tendency to roll to the right. As long as I'm active on the sticks, it doesn't matter too much as I don't hold a vertical line or dive for very long.

My plane has had a few tough landings but is overall in good shape. I have noticed a bit more bending flex in the wing, I don't know whether the spar has delaminated or if it's just my imagination. In any case, has anyone seen this problem before?
