flutter
> Has anybody actually seen RUDDER flutter?
Can't say as I have *seen* it, but I don't know why a rudder would be any less prone to flutter than any other hinged control surface. There is a tiny bit of slop in the rudder linkage on my Super Stick, and it keeps loosening all of the servo screws on the rudder servo faster than I can keep them tight. (it must be some flutter?) Whether pull pull or not I think it is a good idea to use the holes furtherest away from the hinge lines and keep slop to a minimum when possible.
