Hey Minn, I just read your article on CA hinges. I had skipped it for a long time because, well, you know, I already know everything Unfortunately that is not true. You touched on something in there reguarding a "myth" that hinge gap causes flutter. That of course being the myth and the fact is that it does not. I have been for a long time a propegator of that myth and would be very interested in the article you elude to reguarding flutter. Perhaps you could call it "Flutter, Causes and Cures". Because knowing why it happens is worthless if you don't know how to eliminate it. Oh, and throttling back and slowing down are not options![>:]
