I tried tweaking the flaps and it had very little affect. I also came to realize that the air load was now on the control rod all the time, rather than the flap stop. I returned them to the stop...
I used a wedge for a while on the light aileron but did not like the look, plus wherever I went guys kept telling me to change the radius.
In my case I had already over squeezed the ailerons a bit during construction so had to bump the heavy one to raise the wing. I used a hammer and padded wooden block and tapped half of the aileron a bit at a time until I had it zeroed in. Worked like a charm and not nearly as traumatic as I had imagined.
Squeezing an aileron (if they're still a little fat) would be far easier yet... Just go slow and fly it, it does not take much. The change is barely visible...
Good luck!
