Molyneux XM-1000


The only attempt at rotary wing construction in Australia has been made by G.C.Molyneux, a consulting engineer of Melbourne in the State of Victoria.

This rotorcraft, developed from a small-scale experimental model, will be the first Australian-built helicopter. It will have two rotors set in tandem, each rotor having three blades.

Seen in this drawing to be of advanced design, the Molyneux XM-1000 will be Australia's first helicopter (apart from a single-seat prototype model due to fly shortly). A five-seater, it will have a Pratt and Whitney Wasp engine, will weigh 1800kg all-up, and have a range of 560km.

Yet another interesting private venture on the Australian scene is the Molyneux two-seater helicopter, predecessor of the Molyneux XM-1000 five-seat, tandem rotor helicopter powered by a 550hp Pratt and Whitney Wasp engine.
