By sealing the hinge gap you reduce the chance of flutter to near zero..
This is total BS

flutter is airflow passing through the hinge line in one direction causing the control surface to deflect..once deflected the flow reverses, causing the surface to deflect the opposite way.
Again, total BS. This is the misconception of flutter.
It is like saying that if you seal a flag to the pole it will stop waving.
Sealing the hinge gaps will NOT prevent flutter - I have SEEN flutter happen on control surface that were sealed.
If you want to improve a control surface's effectiveness, seal the gap
If you want to prevent flutter, use a servo that is strong enough to hold the surface tightly (The bigger the surface, the stronger the servo needed) and remove all slop from the linkages.
