Yeah, I've made sure that the airplane is trimmed well. Also the wing was attached with rubber bands, and centered. I always do the function checks with the wing on, and all the ailerons move fully in each direction. In the post above, I don't know what "IMO" means, so I'll need to know what that is before I can rule whatever that is out. As for me causing the airplane to bank left, well I guess anything is possible, but I remember having full right aileron in as it continued to bank the opposite direction. Does anyone think it might be the cursed channel 52? Thanks in advance, Mitch
