The A/W 95 is a development of the Adams-Wilson Choppy, which the A/W designation acknowledges. The A/W 95 was designed to comply with the US Experimental Amateur-built rules, since the empty weight is too heavy for the FAR 103 Ultralight Vehicles rules, which stipulates a maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 271 lb (123 kg). It features a single main rotor, a single-seat open cockpit without a windshield, skid landing gear and a twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 503 engine.[1]
The aircraft fuselage is an open frame made from bolted-together and gusseted aluminum tubing. Its 19.5 ft (5.9 m) diameter two-bladed extruded aluminum rotor has a chord of 7 in (17.8 cm) and employs a symmetrical airfoil. The transmission is constructed from a belt and chain mechanism. With its standard empty weight of 271 lb (123 kg) and a gross weight of 490 lb (222 kg), the useful load is 219 lb (99 kg). Fuel tank capacity is 5 U.S. gallons (19 L; 4.2 imp gal), rendering a full-fuel payload of 189 lb (86 kg).[1]
While the A/W 95 is primarily plans-built, during the time that A-B Helicopters was in business some pre-fabricated parts were available.[1]
