I don't mean to belabor the point, but I have never seen a foam core cut up the way you did and it looks to me like it will loose a lot a strength doing that. How do these wings hold up with everything cut out like that. Like I said, I have never seen one cut up like that and am very interested in how they hold up. I have seen them cored out like balsa wing ribs, but never like this. Thanks for the help.
