Ollie...
Somewhere I had heard that an hinged surface would not flutter if the pivot is behind the chordwise CG. Is this an incorrect impression? Or, must the pivot be right at the AC to avoid flutter? That is, neither forward or aft of the AC.
Maybe a better way to ask the question is: What should the relation between the AC and chordwise CG of an hinged surface?
