MAI-223 is a single-engine two seater semicantilever monoplane-parasol with non-retractable landing gear. Perfect controllability in all channels and an excellent pilot view from the cockpit make the plane extremely safe and pleasant for piloting. High thrust-to-weight ratio, high-lift device and landing gear with tail wheel allow to use airplane from short, unprepared runways. Floats and ski landing gear are enabled. Due to the folding wing airplane is very convenient for storage and transportation. 2009 Price: 27150 EURO

The One Aircraft is a 2 + 1 light sporting aircraft produced in Slovenia, the company One Aircraft being set up in 2014.

The aircraft was designed as a joint venture in Slovakia by two companies C2P DOO and KPS Pro DOO, the former carrying out design and the latter supplying metal parts.

Construction is all composite, with a Kevlar roll cage. The aircraft is said to have an endurance of up to nine hours and is fitted with adjustable rudder pedals and adjustable seats. The rear seat can be used as baggage space or for a small person or child up to 90 kg (198 lb).

Production of the aircraft takes place in the town of Grosuplje in central Slovenia, the Company having the ability to produce up to 40 aircraft per year. The Company has also announced that its engineers were in 2015 working on a hybrid variant, this model having an electric engine between the Rotax engine flange and the propeller flange to add an additional 35 kw of power for take-off and climb. The electric engine would be used in the event of an engine failure, providing up to 12 minutes endurance. The batteries are fitted in the wing and under the seats, a regulator being installed on the firewall.

Production was scheduled to commence in 2017.

Designed by Robert Counts an initially developed by Omni-Weld Co around the 37 hp Global Tool GMT four-stroke engine that was also under development at the time, the Questor was aimed at the market for light homebuilt aircraft and a prototype first flew in 1983 with a 30 hp Cuyuna T330 two-stroke engine. It later received the GMT engine.

Development was taken over by Questor Aircraft and finally by Nostalgair.

Only the prototype was completed. It was first registered in 1983 as N701W c/n 0Q-1.

The Questor weighed 270 lb, cruised at 120 mph on 37 hp, burning less than 2 USG/hr.

Ownership was to Francis V Leszczynski of Miami, FL, US.

The certificate expired on 30 September 2011.
