Dave,

Are those root and tip ribs you show on your wing plan accurate? If so, is that the exact center rib? If those first two statements are true, (and I'll bet they are), can you do a foam wing template? That would be simply taking the root/tip templates and taking 1/16" off top/bottom to account for the wing sheeting. It would sure make my life easier and then it would be much easier to make foam wing/stab of the Aurora. Let me know either here or in PM....and think that a few people might like a set of cores..
