Sealing your hinges is a minor aid in reducing flutter. ...
Flutter is introduced because of harmonic vibrations caused and exacerbated when the plane is flying over its design speeds. ...
... the air passing through the hinge gap is overstated as being a big cause of flutter.
I agree with your post.
The belief that flutter is prevented by sealing the control surface hinge gaps persists in the forums no matter how many times someone attempts to explain how flutter occurs.
That's funny! When I was in the Navy and worked on various A/C the control surface had sealed alerons and elevators!
