I've broken one hinge point over hundreds I've used. That one was mounted at the mottom of a rudder hinge line and after smacking the end of the rudder on asphalt during a couple of pull ups into a hover it finally gave up. I don't know of anyone else that's broken one where the surface didn't flutter like crazy first. Even then, most hinge [points get pulled free of the mounting holes during flutter after the holes have been enlarged from the vibration.

Flat hinges are another story. I've broken many ca and flat plastic hinges over the years during maneuvers in flight.
