Ahhh, the ultimate plank. This bird would be quite a sight in the air with its 12-foot wingspan. My favorite design feature is the way the fin blends into the canopy. I'm not sure if a .15 would be enough; perhaps electric power would be more suitable. The single wheel in the center is another prominent design feature that fits in with the sailplane-like nature of the model, but it would probably make more sense to leave it off and belly land in grass. It would be interesting to try it without the tip panels, using radio programming to convert the elevators into elevons.
