Please keep in mind that there is no way with the existing design to aerodynamically balance any portion of any of the flight control surfaces except the vertical fin.
Also keep in mind that the resistance to cracking/failure of the surface or the panel is a design feature and simply adding mass balance pendulums to the existing design can result in failure of the horn, the surface, the hinge, the trailing edge spar region, the control system.......
Flexure and flutter are totally unsimilar behaviors. Flutter is uncontrolled response to exitation and unless managed instantly and correctly will result in damage - frequently very severe. Flexible structure is a designed feature and is used to allow long life and a softer ride.
I want to see the results of CH latest involvement.
