It sounds like the sort of thing that might appeal to people going for their first build. Although I lean more to scale airplanes I generally keep an airplane or two that I can just toss in the car. As for selling in the USA I think the practicalities of shipping and marketing might be a bigger issue than demand for the airplane. My LHS did business for years as Lazerworks. In recent years before he retired the owner mentioned that shipping was getting to be a hassle. He also had difficulty keeping technical help. As soon as someone demonstrated a good skill set with the website and making kit files they would leave for the big city where they could make more money.
