All_Taken.....The play in the rods is simply the torsion or twist they allow due to their own material. In other words, I can push on the ailerons and see them move while the other end of rod (on the servo end inside the fuselage) does not. The rod itself twists allowing the play and contributes to the flutter.

Dr1.....Thanks for those comments and I appreciate it. Will consider the separate servo idea as that would be the best solution.
