The Aquilair Kid ultralight trike was designed and produced by Aquilair 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 was supplied in modular form, with the chassis, engine, reduction drive and propeller all available separately, Priced at€7912 in 2011. 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.

Supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft, production was completed in 2014.
