I just got my Europa video back, and have had a chance to look at the
"rudder flutter" that was recently discussed. I have had control surface
flutter on Radio Control models and when you have it you know it. What
was shown on the video looks like a possible lack of sufficient rigidity
in the tail cone. The degree of movement looked to be enough that I
think I would want to investigate methods of adding rigidity to the tail
cone. Possibly glassing in a honeycomb bulkhead to help keep the
fuselage sides from apparently deforming.
I think this is a question I would like Peter to pose to the experts at
Doncaster.
