The Keitek Streamer is an Italian ultralight trike, designed and produced by Keitek of Remanzacco. The aircraft is supplied as a complete ready-to-fly-aircraft.[1]

Design and development[edit]

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 450 kg (992 lb). It features a strut-braced "topless" Hazard 12S or 15S hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.[1]

The Streamer has a double surface wing covered in Dacron sailcloth. The Hazard 12S 9.8 m (32.2 ft) span wing has supporting struts and uses an "A" frame weight-shift control bar. The powerplant is a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912UL engine. The fuel tank includes internal baffling and the engine oil tank is enclosed inside the fuselage.[1]

With the Hazard 12S wing the aircraft has an empty weight of 185 kg (408 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 265 kg (584 lb). With full fuel of 64 litres (14 imp gal; 17 US gal) the payload is 219 kg (483 lb).[1]

The Hazard 12S wing has an area of 12 m2 (130 sq ft) and is intended for experienced pilots, while the Hazard 15S wing has a wing area of 15 m2 (160 sq ft) and is envisioned as a school and student training wing. The Hazard 12S wing gives a cruising speed that is 30 km/h (19 mph) faster than the 15S wing.[1]
