Model of a twin-rotor helicopter designed by Grevor Chilton 'Bing' Molyneux. The model has a small stand incorporating an electric motor to drive the rotor blades for wind tunnel testing. The mock-up engine is a 130 hp Gipsy Major. This model was subjected to wind tunnel tests at the Aeronautical Research Laboratories (ARL) in Melbourne in May-June1954 and was subsequently donated to the Museum. It has a stand and an electric motor to drive both rotors via a gearbox and shafts.

The initial design was intended to be the first commercial helicopter manufactured in Australia by the Molyneux Helicopter Co. Pty Ltd at Essendon Airport, Melbourne. Construction of a full-size prototype began at Essendon but was not finished. A larger commercial XM-1000 version was planned but not built. The Molyneux Helicopter Co. then concentrated on the construction of truck bodies and hoists.
