Design and development

The T22B features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, skid landing gear and a four-cylinder, air-cooled, four stroke 160 hp (119 kW) Lycoming O-320-B2C aircraft engine.[1]

The aircraft fuselage is made from composites. Its two-bladed rotor has a diameter of 7.6 m (24.9 ft). The aircraft has a typical empty weight of 355 kg (783 lb) and a gross weight of 650 kg (1,433 lb), giving a useful load of 295 kg (650 lb). With full fuel of 70 litres (15 imp gal; 18 US gal), the payload for the crew, passenger and baggage is 244 kg (538 lb).[1]

In 2015, reviewer Werner Pfaendler described the T22B's design as "elegant".[1]
