History:
The One Aircraft is a 2 + 1 light sporting aircraft produced in Slovenia, the company One Aircraft being set up in 2014 to “design the ultimate, safe, affordable, attractive and top performance sport-family aircraft with 2 + 1 seating configuration that would fit in existing LSA and CS LSA (2-seat configuration) category as well as future ELA1 and other emerging categories.” The driving force behind the Company and the design of the aircraft was Iztok Salamon.
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. 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.
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 was scheduled to commence in 2017, the Australian and New Zealand agent being Aerosport Aviation Ltd which announced it was importing an example as a demonstrator.
