BB Microlight BB-two seater

The BB Microlight BB-two seater is a Hungarian ultralight trike, designed and produced by BB Microlight of Baja, Hungary. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.

Design and development
The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg. It is marketed in the United States in the Light-sport Aircraft category as an ELSA by Manta Aircraft.

The aircraft features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear with wheel pants and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 8.1 m span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The standard powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp Rotax 503 engine, with the liquid-cooled 64 hp Rotax 582 and the two cylinder, air-cooled, four-stroke, dual-ignition 60 hp HKS 700E engines optional.

The aircraft has an empty weight of 91 kg without the engine fitted and a gross weight of 375 kg. Full fuel is 26 L.

A number of different wings can be fitted to the basic carriage, including the US-made 40% double surface Manta RST and the 80% double surface Manta Orca 12 RST. The Manta RST comes in four sizes, graded by wing area: 12.5 m2, 15.5 m2, 17 m2 and 19 m2. The Hungarian-made 16 m2 BB Microlight BB-02 Serpa or the 14 m2 BB Microlight BB-01 Bence are also available.
