Me too, I had a hinge delaminate on a Kingcat, both ailerons delaminate on a Ultra Bandit and an aileron hinge split on an A10. I repaired the Ultra with G10 hinges with the long pin type pivot.
I modified the ailerons on my Airworld Hawk before I flew it, they are more scale anyway. Lastly I'm awaiting delivery of the new FB Hunter, that has pin(rod) hinged ailerons and "live" hinged elevators so, you know what will happen to them!
