Thanks Sinergy, I'm already sealing all the hinge lines on my glow planes, not so much to prevent flutter but because I find that the surfaces become more effective and the trim settings are more consistent.

Silversurfer - thanks for the instructive discourse! I figured out the metal to metal issue for the throttle linkage but could only guess at the rest. Your post definitely clears up the issue for me! Was rather foolishly hemming and hawing on whether to save a few bucks and just put in Z bends as almost everyone I know has been suggesting. Sorry, I guess its a silly question from a newbie; thanks for your time and perhaps you've just saved my plane from a crash!
