Design and development

The Skycruiser was Bautek's first trike design and was designed to comply with the German 120 kg microlight category. The aircraft features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat open cockpit, tricycle landing gear with finned wheel pants and a single engine in pusher configuration.[1]

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 9.5 m (31.2 ft) span Bautek Pico L wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a specially modified and tuned twin cylinder, air-cooled, four-stroke, 38 hp (28 kW) Briggs & Stratton Vanguard 1000 engine. This engine provides good fuel economy with a low noise level of 55 dB and produces a cruise speed of 90 km/h (56 mph).[1]

The aircraft has an empty weight of 75 kg (165 lb) without the wing fitted and a gross weight of 238 kg (525 lb). The fuel tank holds 30 litres (6.6 imp gal; 7.9 US gal) of fuel.[1]

The Skycruiser is German DULV certified.[1]
