My purple 122" Extra has 62 flights on it, and while the rudder and elevator hinges were failing at 5 flights, the aileron hinges were still more or less okay at 62 flights. Not so with my blue 122" Extra. The rudder and elevator hinges also failed quickly, but the aileron hinges failed, as well, at 34 flights. I'm cutting out the 9 junk hinges on each aileron and replacing them with 13 Robart round hinges. Really wish Pilot RC would just jig drill for round hinges and let us glue them in ourselves. It's so much faster than cutting out their junk hinges and dealing with all that.
