Charles:
I was trying to point out you continuous reference to speed being the culprit. Most of the problems I have read about flutter on these 2 airplanes did not involve speed. Mine certainly did not.

Personally, and with no research backing,I think that the culprit is one servo (no matter how strong) on huge control surfaces.

Apparently Dave Patrick thought so also as he redesigned both planes for dual servos now. So far, I have not heard of airleron flutter with a dual servo setup, have you?

I am rebuilding my Edge and will use 2 servos on the wing and will let you know. And yes, the gaps were sealed.
