Okay, so this one was my fault, I admit it. But I had a heavy right wing from the first flight. Not too bad, but bad enough. The electric trim had to be almost all the way left when the tanks were even, and if the right one had more than the left, trim wasn't possible.
I had noticed that when you let go of the stick, it would move a bit right, starting a gentle right turn. If you held the ailerons centered (by watching their alignment with the flaps) the plane continues on level.
I pulled the wing inspection plates yesterday and found that the right aileron bellcrank wasn't centered properly--when the gage was in place, the aileron showed a left turn position, off about 1/4". I readjusted the linkage. Now the trim is just a little off center to the left and I plan on checking it again with the help of another person as I may not have it exactly correct just yet.
To correct the heavy right wing, I shortened the right aileron push tube by screwing it in (and readjusted the long tube to bring both ailerons even with the flaps.) I would put this on the list of things to check when dealing with a heavy wing. The change in leverage is substantial to the trim!
