thanks. I have observed structures in flight.
I have flown several rc airplanes beyond vne and witnessed the crafts begin control surface flutter and the event continues through to destruction of horizontal stabs for elevator flutter and wing destruction from aileron flutter. I have built replacement rc aircraft and modified the control surfaces with weights forward of the hinge location to eliminate flutter, but I have never targeted neutral balance. instead I target balance to exist forward of the hinge. like an arrow in flight I want a rigid structure that is "nose heavy" for stability. I have not found the engineering analysis that can quantify the forces allowing for prediction of flutter events. jg On Sat, Jun 4, 2022, 2:58 PM David Maultsby <dmault...@win.net> wrote: > John, > > > > I believe doing a quick “Google” search for “Flutter Analysis” will lead > you to a much fuller understanding of calculating your correct control > balances.
