In the Netherlands, we are watching you!
For wing design, not a matter of argument, I want to exchange views. In my opinion, the wing without fuselage will carry it's own weight without any bending in tight curves. The fuselage however will need to be accelerated as well, and imposes a bending moment on the wing. This is the same in SSC as in ACES 1/12.
Paper wing skins are plastic-like when fully hard. Near the wing center piece I laminate them with extra plies, up to 4 near the fuselage for a total paper thickness of 0.5mm. This is extremely strong, and is the same main principle as used in airliners with stressed skin wings.
This wing construction has extreme damping characteristics, and will not shatter on impact or flutter. It just gets dented locally, and is repaired by cutting out a piece of foam, and add one or two local paper layers after sanding to shape.
What is the airfoil you use?
I use a flatbottom foil of own design with droop-snoot layout, which is very simple to build. In SSC with short tail feather coupling it would need quite some aileron reflex to cancel foil pitch moment, but it is stall free up to 18° AoA, and has very low air resistance in tight curves. Air resistance is very low with Cl @1.5 . Negative curves are not very good, so you need to roll before banking.
