I had exactly the same issue. I followed Vanís advice and slotted the heavy wing aileron brackets thereby moving the aileron vertical position 1/32 of an inch. It fixed the heavy wing instantly. I then ordered new blank brackets, drilled them to the new position, painted them, installed them and it flies beautifully with minimal trim. Obviously youíll need to trim for single pilot and fuel usage but thatís normal.
