Has anyone else had this problem? I have a Tower Trainer 60 that upon first flight rolled left fairly hard. I was able to trim it out but there is a clear offset to the ailerons now with the stick at center. First let me say I take my time and build true weather it be a kit or arf. Coul there be a defect in the wing? It looks straight. I checked and double checked the tail and the engine alignment. Have double checked the cg and the latarial ballance. The only thing I can think at this point is a warped wing, but if it is it cant be much. Like I say, it can be trimmed out, but it bothers me having to hav the offset while it should be center.

Thanks Bob
