The Aero Eli Servizi Yo-Yo 222 (sometimes written YoYo) is an Italian helicopter designed and produced by Aero Eli Servizi of L'Aquila. The aircraft is supplied complete and ready-to-fly.

Design and development
The Yo-Yo 222 was initially designed for a higher gross weight of 495 kg, but later versions were lightened to allow a gross weight of 450 kg 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 Lycoming O-320 engine.

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."

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. The initial version of the aircraft has a typical empty weight of 322 kg and a gross weight of 495 kg, giving a useful load of 173 kg. With full fuel of 68 L the payload for the pilot, passenger and baggage is 124 kg.
