I can see where this would be needed in what I would assume would be the working part of the wing ( mostly outside the WAFs ). But not inside the fuse where we would be drilling holes for routing to the tail, or where I feel most changes should take place in jumping to the other side of the spar with controls or whatever. I would think that where the spar joins the fuse, there is one hell of a stress riser! Steve McGee EndeavoWI KR2SW
