I'm trying to design a plane that sort of looks like a 1909 Wright Flyer but it is basically a bi-plane pusher Cub. It has one engine (centered and ahead of the wing LE) driving two fixed pusher propellers. When I try to fly the plane in X-Plane it says that a Mics Body has no frontal area and refuses to fly.
I've also noticed that although there is a place to note what kind of engine there is no way to locate it forward of the "transmission" (which is not a conventional transmission but is really just smaller sprockets driving chains going to larger sprockets bolted to the props.) I also haven't figured out how to locate the crew on the LE of the lower wing, make a fuselage that is only a truss work with no skin. Manual isn't too useful for this kind of design.
Any ideas?
