Pretty. If you are having issues bending balsa sheeting into place, soaking it in warm water can really loosen it up and allow it to bend at crazy angles, and the best part is if you do it correctly it holds its shape almost perfectly after it dries. You can also do it with acetone, which works even better, but you have to be careful not to fumigate yourself by doing it in an enclosed space.
Is the wing going to run through the fuselage? Honestly in this case I would be more inclined to have a two-piece wing and have a carbon spar affixed in one of them, while you have a spar tube living inside the fuselage. The wing would then be held in with nylon bolts running through tabs extending from the inside edge of the wings (these will not be taking any bending load, only tensile load) and then the nuts retaining said bolts would be attached to a piece of ply or some other hardpoint inside the fuselage.
