Unfortunately... the geometry of the control linkages is only one factor in flutter control, and the distance from hinge line to clevice on the control horn needs to be larger as the aircraft becomes larger. (and some other factors can change what will work and what won't)

Do a search on Flutter, and you will find a LOT of threads discussing the ways to prevent it.

The most common thing to break first with flutter is the hinge, or the servo gears. I have seen aileron flutter rip a wing off of one aircraft.
