The one I was talking about was post #5. The wing has so many cutouts that I just don't see how it will stay together. I have been out of the hobby for a few years and we used to do a little coring of the foam cores, but nothing like that. That is why I was wondering if it will hold together. I know things were going to change a little, but boy are they different. I just noticed that the wing I was talking about was not yours. Guess I need to read a little closer, or pay more attention.

The strength of a wing comes from the sheeting, the foam only holds the shape of the sheeting. Extreme coring like that hardly affects the strength at all. If you fully sheeted a wood wing, it wouldn't need spars at all, etiher.
