As other have posted - not your problem.
I've worked serveral RVs with a heavy wing. It has never been caused by aileron trailing edge issues (so any squeezing is just treating the symptom, not the problem).
I've posted on this in the past, as have others, but here is the short version:
- Do not rely on the bell crank gig, it just gets you in the ball park.
- Defer wing tip install until after the wings are on and all other control surfaces are perfectly rigged. The wingtip trailing edge can be moved up/down an inch so doing this before everything else is done yields unwanted results.
- Get the flaps rigged. Are they really fully up? Go look at other well built RVs to see what "fully up" looks like.
- Now adjust the aileron pushrods so that both aileron trailing edges line up with the flap trailing edge. I also use the wing template that was stenciled on my old RV-8A slow build crate to verify the ailerons are really in trail.
- With the ailerons locked into trail, now go look for the leading offenders of a heavy wing - the aileron brackets. Is the gap between the top of the ailieron and wing skin the same across the aileron - and the same with the other aileron? Use a straight edge across the wing and aileron to measure the trailing edge gap with the straight edge. It is the same across the aileron and the same as the other aileron?
If any of the above measurements fail (and it is not because you have a twist in a flap or aileron), it is time to rehang the aileron. I think Van's still sells the non-drilled aileraon brackets for this purpose. If you have a good welder they can fill the hole and you can re-drill but the no hole brackets are cheap.
After all this is done, then and only then fit the wing tip.
