Aquilair Kid
# Aquilair Kid

The Aquilair Kid is a French ultralight trike designed and produced by Aquilair of Theizé. 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 (992 lb). The aircraft has a maximum gross weight of 300 kg (661 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat open cockpit, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from metal tubing, with its wing covered in Dacron sailcloth. Its 9.9 m (32.5 ft) span Star 12 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 (37 kW) Rotax 503 engine, with the 40 hp (30 kW) Rotax 447 and the 64 hp (48 kW) liquid-cooled Rotax 582 optional.

With the Star 12 wing the aircraft has an empty weight of 132 kg (291 lb) and a gross weight of 300 kg (661 lb), giving a useful load of 168 kg (370 lb). With full fuel of 30 litres (6.6 imp gal; 7.9 US gal) the payload is 146 kg (322 lb).

The aircraft is supplied in modular form, with the chassis, engine, reduction drive and propeller all available separately. A number of different wings can be fitted to the basic carriage, but the Star 12 was formerly the standard wing offered. The chassis incorporates an under-seat pivot system that allows the wing to be mounted and then raised into position.
