I have complete confidence in the ailerons and elevators with film hinges, but I do wonder about the rudder, since it will be pull-pull with a really strong servo for the huge rudder. Lots of strong forces in various directions on the hinge back there. I wonder how film hinges would hold up to that over time. When the forces are in some directions, it may tend to peel off the film hinges from the attached surfaces.
