If the stab was not dynamically balanced close to the MAC you would have seen this problem before now. Sounds like a linkage let go. Dantley flew his Mig-29 for several flights with a P-200 and never had any issues with flutter so I dont think they have the pivot point wrong. Static balancing wont help flutter, most full scale jets do not have statically balanced stabs, why should ours?
Sorry you are wrong. Static balancing is there exactly to help prevent flutter. Full size jets have irreversible hydraulic controls. Our models do not.
The old Byron F16 was a classic example. They where nortorious for rudder flutter, to the point that many people glued them in place. But a balanced rudder did not flutter.
