I don't know if you've seen any of my 6A flight reports...
The right wing was heavy enough, that the external servo controlled trim tab on the end of the right aileron, wasn't quite enough to keep level. Yet the stick forces were very light. I also noticed that the ailerons were in near perfect trail when the stick was held to keep the plane level. And the right would move up/left down (of course), when not holding the stick or using trim.
Before doing anything, I installed the wheel pants after the engine got some breakin hours on it. The wing was still just as heavy. At first, I figured I'd tape a small wedge on the bottom of the left aileron, just as I had done on my rudder. The old six rudders had no offset.
When taping the wedge, I noticed that the radius of the left aileron was slightly thicker than the right, by about 1/16 of an inch. One of the methods of correcting a heavy wing, is to slightly flatten the trailing edge of the opposite aileron. I'm not sure about "8" ailerons, but unlike the "9", mine has bent trailing edges.
I spent about a minute with some sheet metal hand seamers covered with duct tape, and slightly squeezed about half the length of the aileron. This trial squeeze worked perfectly, and the plane flies level with the aileron tab centered.
