Abstract: The fuselage or airframe is a solid, characterised as two-dimensional, plastic moulding. The flapping wings pivot at the inner ends both to a pin on the airframe. Connecting-rods go from the crankshaft to intermediate points on the wings. The various pivot connections are made by snapping resilient split sockets onto respective pins, so no tools or fasteners are needed. Designed thus, the aircraft can be manufactured in kit form, wherein all the required plastic components are formed together in a single injection, the components being detached for final assembly.
