Phase 1 in rv8....have a heavy right wing...it starts at 157 mph and gets move pronounce as speed increases. Autolilot compensates for it, but hand flying feels like about 2 to 5 lbs of pressure on stick to keep level. Adjusted rt flap up a shade...no joy...leveled flaps again and raise rt aileron up....again no joy. Last thing to try is squeezing left aileron per Van's heavy wing instructions. Question is...the fact that heavy wing dosen't appear until increasing airspeed indicate something else going on that squeezing wouldn't fix....thanks
