During my Phase 1 testing I had a heavy Left wing. I didn't notice anything at low speed, but did once speed got above 180mph. I was breaking in my engine so didn't spend much time at lower speeds. At 200mph, if I relaxed my hold on the stick, the plane took a hard roll left, the faster I went the faster it rolled. At WOT it was scary for a lowtimer like myself. As I released the stick, My ailerons would deflect (left went up, right went down). So after making many calls to RV'rs, I measured the aileron outboard hinge placement. Sure enough my left aileron hinge pushed the outboard leading edge above the wingskin. slotting and dropping the hinge and I was flying balanced at cruise and higher. I still don't know how it affects slow speed, but I don't notice any adverse effect.

Then during more high speed testing I found a new problem. Unstable in roll axis. I would tap the stick sideways to check stability, but instead of damping out, it would rock back and forth getting worse with each oscillation. After 4 or 5 rocks, I had to tighten my grip to keep things in check. A check of the trailing edges of the ailerons revealed a bloated radius edge instead of a flatter profile. I fixed this using 2 paint sticks with tape for scuff resistance and my seaming pliers. A very subtle squeeze on both ailerons took care of the unstable roll.
hope this helps
