The Yo-Yo 222 was initially designed for a higher gross weight of 4950NaN0, but later versions were lightened to allow a gross weight of 4500NaN0 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 1720NaN0 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 7.661NaN1. The initial version of the aircraft has a typical empty weight of 3220NaN0 and a gross weight of 4950NaN0, giving a useful load of 1730NaN0. With full fuel of the payload for the pilot, passenger and baggage is 1240NaN0.[1]
