Same problem as I had
Before I would do anything, if the trailing edges of the ailerons are not squeezed as tightly as they should be, I would proceed slowly by squeezing the light wing aileron trailing edge. I had a heavy wing, can't remember which way, and my right aileron was high like yours, so instead of squeezing the ailerons, I slotted the right aileron brackets and lowered the aileron, this produced a heavy wing the other way, so I slowly brought the aileron back up. But when I was close to getting rid of my heavy wing I devoloped a little aileron snatch, because the trailing edges weren't squeezed right. 3 minutes with Mike Seagar and his hand seamers, no aileron snatch, no heavy wing.
