RE: Big Stik Low Wing Mod
The wing stays as designed - same side up. You flip the fuselage & attach the wing from below. Only have to move the ply bolt reinforcement plates. At a former club several modelers turned Road Runners (a stik, basically) into a stand-off scale crop duster just by flipping the fuselage. But you do have to figure out how to counteract the built-in down thrust and right thrust when you flip the fuselage.
