it seams as if the pocket would have to be recessed in the leading edge? i tried one last night and to ge thte hinge point to line up anywhere close you have to recess them and then what about the set screw do you drill an acess hole? i love the hinges and drilling them are a pain in the rump ive used just the hinges before and if your doin alot of 3d work as I am the multiple wing and aileron setup would rock if I ever had to use them. There is a Jig according to robarts website i measured out all of mine before hand both wing and aileron i also have multiple rudders and elevator halfs. well any input on recessing the pocket?
