Yes, the plane was designed with 3D in mind. When I purchased it 4 yrs ago, the builder told me (when I asked him if it was capable of hovering) his son had been hovering his regularly.

I will try and take the side view of the wing tomorrow. But, the wing is symetrical. Inside of the wing is nothing more than a yard stick glued on edge. It is approximatly inline with the pointed edge of the wing. If the wing were opened up (unglued at the back and both ends) it would be exactly the same measurement on both halfs. It would be like a hot dog bun.

As for a wing saddle, the orange piece atop the wing (coroplaste also) wraps around and under 2.5", both front and back. This keeps the wing resting on the gutter pipe evenly, with out crushing the bottom in the center of the wing.
