In standard construction, the sides go over the spars, and is covered with 1/8" plywood. There is a hole, but it is covered by the 3" of plywood forward of the hinge.
In foam construction the top has to be glued on top of the sides, in order to give it shape. Hence the problem.
Now lets suppose, that instead of gluing the foam to the top of the sides, I reverse it.
So I put a bunch of holes in the sides for the spars, 2" below the top. Then I glue the top to the spars. The shape is retained, and the sides cover the hole, as in standard construction.
I'll model that up tomorrow evening and show you guys.
