so you can build in flutter proofing by balance, absence of hinge slop
and control tensions but in the end it is up to some careful test
flying to determine whether there is an onset of flutter.

The flutter test for the brave, goes something like this. Get plenty of
altitude, say 8 thousand feet AGL, put the plane into a pretty steep dive,
WOT, and give the stick a sharp rap. If the plane keeps flying, and you are
satisfied with this speed as Vne, OK, you are done. If the plane starts to
flutter, and the wing falls off, use you parachute, now.

Oh, you did have a parachute on, didn't you? g
