I think it has been proven to work, tested to extreme limits, and even forced to break with no advances in the break. It reminds me of a story I once read about the tapered rod gear by Steve Wittman. He couldn't sell the idea because it "looked" flimsy. History shows what happened. Advances cannot be made without ideas. Build it and they will come. :-)

As a Tech Counselor, I have inspected a Zenair Zodiac (Chris Heintz design) that used the aluminum skin as the aileron hinge. It seemed to work well and was designed to have a reasonably large bending radius that should cause a minimum of fatigue. The builder showed me that it was an optional construction method in the plans. I would think there would be a finite metal fatigue life to it, but then I didn't do the engineering calculations. I do know for a fact that the plane was completed and flown. As was mentioned previously, this is also common practice on RC planes, including some that have speeds up to 200 mph.
