I'm going to run uni carbon down both sides on the wing as a "spar", and I'm going to slip some pre-cured stuff in as an I beam spar. I've done this on a Discus launch glider, and it works well. Most of the gliders that I've done have had fully finished LE and TE. The foam cores I bought today do not, so I'll need to shape a wood LE before bagging.

I'm going to try to hinge the ailerons/flaps with a rod and some robart hinges, rod glued to TE of wing, and the aileron LE rounded out. Hinges will go through the rod. Never tried that on a power plane, so if you guys have any more suggestions, please lemme hear them!
