In some ways, swept back leading edge will act much like dihedral even with a flat wing.
A wing gets most of its strength from structure near the wing skin (or the skin itself) Main thing done by the foam between the skins is to maintain the spacing between the skins. (whatever skin you use...)
Adding a packing tape skin (or Doculam, Monokote... any covering) to a foam wing adds a huge amount of stiffness and strength.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

I took a kit intended for 1/16 balsa wing skins over foam and skinned it with 1/64 inch ply, replaced the balsa LE with white OAK. and came out significantly lighter than the normal for that model's wings (monokote covered in both cases, no fiberglass)
Because it was a slope soaring racer, I had to ballast up to get enough weight to be competitive. (the planes were perfect at 18.25 oz, heavier or lighter was slower.) It was the fastest plane on the slope, beating the planes build by the designer of the kit. (who flew at our site)
And the wing was MUCH stronger and stiffer then the balsa sheeted ones.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.
