Design and development

The Yo-Yo 222 was initially designed for a higher gross weight of 495 kg (1,091 lb), but later versions were lightened to allow a gross weight of 450 kg (992 lb) to qualify under the European Class 6 microlight helicopter rules. The aircraft features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit, skid landing gear and an American-made four-cylinder, air-cooled, four stroke 172 hp (128 kW) Lycoming O-320 engine.[1]

Greatly resembling the Robinson R22, reviewer Werner Pfaendler, describes it as "obviously the result of a close look at the world's bestselling two-seater helicopter, the R22."[1]

For lightness the aircraft fuselage is made with extensive use of carbon fiber reinforced polymer and fibreglass. Its two-bladed rotor has a diameter of 7.66 m (25.1 ft). The initial version of the aircraft has a typical empty weight of 322 kg (710 lb) and a gross weight of 495 kg (1,091 lb), giving a useful load of 173 kg (381 lb). With full fuel of 68 litres (15 imp gal; 18 US gal) the payload for the pilot, passenger and baggage is 124 kg (273 lb).[1]
