Good Point... That is what I was worried about. I also just though about the fact that the ailerons are buit up barn door type and not solid strip type. That means that there is definitely no material in the ailerons to work with, however, if you really wanted to use these hinges, I suppose you could open things up and add some material - but this is probably not worth the effort in my opinion. I plan on nice and easy scale flying for mine so I am not too worried about the hinges.
