I had a senior telemaster with one piece wing, but at that time, there were other folks modding theirs to be two piece.

The senior telemaster wing is very easy to build, and uses turbulator stringers instead of a D-tube design. I think if you used a wing tube, you could easily build this into it when building the wing. The only issue may be keeping all the dihedral, but still not too hard.

Cut some plywood spars, add some sheeting, boom, you're done.
