Design and development edit

The Pitbull II is a two-seat development of the North American Rotorwerks Pitbull Ultralight. It was designed to comply with the US Experimental - Amateur-built rules. It features a single main rotor, a two-seats in side-by-side configuration open cockpit with a windshield, conventional landing gear and a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 100 hp (75 kW) Rotax 912S engine in tractor configuration. The 110 hp (82 kW) Subaru EA-81 and Subaru EA-82 auto-conversion powerplants are optional.[1][2]

The aircraft's rotor has a 30 ft (9.1 m) diameter and the cockpit has a 40 in (102 cm) width. The tailplane is strut-braced and an electric pre-rotator is standard. A small baggage compartment with a capacity of 20 lb (9.1 kg) and a volume of 2 cu ft (56.6 L) is fitted. The recommended power range is 90 to 160 hp (67 to 119 kW). With its empty weight of 440 lb (200 kg) and a gross weight of 1,025 lb (465 kg), the useful load is 585 lb (265 kg). Construction time from the factory assembly kit is estimated at 100 hours.[1]

The aircraft is intended to resemble the autogyros of the 1930s and as such it uses a radial engine-style round cowling, rounded rudder, barrel-shaped fuselage and other antique styling details.[1][2]
