all with no failures. Some of these are speed planes for racing some are aerobatic and get some extreme rates and power so I think they get their share of stress.

Airgar, it seems we are at the opposite ends of the spectrum on this issue but based on your experience I don't blame you for switching to a differant hinge.

Rjbarthel, If it ain't broke don't fix it. Don't start trying to solve a problem that you don't even have yet, just keep an eye on your hinges and spend your building time on new projects.
