Most RC Planes dont come as a "package"
For instance, my F-104 came as a fiberglass molded fuselage, plywood formers, foam core wings, with sheeting. Once it was all built up I had to fiberglass the whole thing, then sand, sand and sand some more, then sand again, then do some more sanding, then prime and paint it. Then had to install all of the equipment, including engine, retractable gear, gear doors, pneumatic lines and tanks for the gear, brakes, radio/electronics, and telemetry system... In addition I cabled and installed scale nav lights on it. So saying something is in the "package" in the RC air world, is a totally different animal than in the car world. And THIS is from a kit based plane, not to mention the scratch builders, who start with drawings and build from there!
Dave: I have launched estes rokets off of my TREX 700 heli, which is in a scale apache fuselage
