Flying Machines FM301 Stream

The Flying Machines FM301 Stream, is a Czech ultralight trike, designed by and produced by Flying Machines s.r.o. of Rasošky. The aircraft is supplied as a complete ready-to-fly-aircraft.

Design and development
The FM301 was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg. It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a cockpit fairing, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made with a monocoque fibreglass carriage, with its double surface wing covered in Dacron sailcloth. Its 9.5 m span Quasar wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, four-stroke, dual-ignition 60 hp HKS 700E engine, with the two-stroke 64 hp Rotax 582 and the four cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp Rotax 912UL or 100 hp Rotax 912ULS engines optional. With the HKS powerplant the aircraft has an empty weight of 175 kg and a gross weight of 450 kg, giving a useful load of 275 kg. With full fuel of 42 L the payload is 245 kg.

The unusual fibreglass structural construction allows internal fuel tanks and also permits a large unobstructed baggage area. The FM301 also has a unique wing mast system that allows the wing to be assembled and mounted on the carriage single-handedly.
