So the outer skin would only contact 50% of the wing area? Wouldn't there be a bunch of 3/4" squares on the surface that have no support and be prone to damage? Maybe fill the voids with micro and sand smooth but that would be heavy I'd think...I'm an armchair pilot still so I don't really know.

When I moved the wings to the storage area I could hear the foam under the fiberglass cracking with moderate handling, which I don't care for at all. Mark L's decision to layer the wings using a fiberglass-foam-carbon fiber sandwich is the common sense solution, but in order to insure that my new wings will handle the rigors of being taken on and off regularly , I am considering an additional step. In this step, prior to laying up the outer layer of CF, I will put a crosshatch of 3/4" wide Vee grooves in the outer layer of foam, and then fill those grooves with a layer of CF, which would form a grid of reinforcing angles UNDER the outer skin when that is applied. It seems like a reasonable extra bit of work to do for some extra peace of mind. I'm also going to add four 1/4 inch threaded inserts into the top of the spars (2 front , 2 rear).That allows me to put Eyebolts into the wings during ground operations and lift them using a boom, thus being able to load, unload and attach the wings by myself without putting stress on the skins. How do those idea sound to my fellow netters, particularly you Mark L?

This is an actual shot coming out of Land of Enchantment Flyin this past weekend. Mine shipped yesterday, should be here tomorrow!! http://www.youtube.com/watch?v=QCWf8-rhfzU The following is a synthetic approach of an ILS. The GRT unit superimposes the HITS (highway in the sky) square boxes instead of the localizer/GS needles and you simply fly through the boxes. http://www.rocket-boys.com/images/GRT_SAP_HITS.wmv Let this thing load before you play it. If you are using dial up, forget it!! I post these just to motivate all builders. We in the experimental world continue to have access to the best of the best at an affordable price. Anybody care to guess what a certified unit would cost to do what this unit does? Life is good. Keep gluing, I'll keep pounding.
