As I have modified the plane for speed the original wedge I installed became ineffective. This is mod I made to our RV-6A to provide a removable ground adjustable rudder trim tab. In a 138 statute mile race with 5 turns last Saturday (10-2-2010) the plane averaged 208 mph and the ball stayed centered in straight and level flight. The same condition was true in the flights from Fayetteville, Arkansas to Sherman Texas and back to participate in the race. I recommend considering something like this in the original build instead of the almost standard trim wedge in RV-6s.
