Perhaps a contrary note....I use Hayes "living" hinges (used to be Kraft-Hayes), and I put them in with slow dry epoxy, after roughing them up a little with course sandpaper. No pins of any kind. I have been doing this for most of the 26 years I have been in RC, including at least a dozen or more piped pattern planes in the "go fast" pattern days, and airplanes up to 1.5 glow size. Never a hinge failure.

Correct me if I am wrong about this, but as long as a hinge does not shear off at the hinge line, I do not believe there is a lot of force in the direction of pulling the hinge out of its slot. Any thoughts on this theory?
