Well I just got back from flying the four star and everything actually went pretty good. I didn't have to trim the elevators as much as before, and rolls were alot better than before. When I took the wing off I realized that I avoided disaster by pure luck. The battery had come loose and wasn't secured at all. The battery wire that ran pass the elevator servo which I had taped down came loose and was right under the servo arm. I think the battery came loose after I did a less than perfect touch and go. Now I just need to find a better way of securing the battery back there.
