By 2012 the A-B Helicopters website had been taken down and plans are no longer available.[2]
The design was developed into the Vortech A/W 95 and plans for that version remain available from Vortech.[3]
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 2540NaN0. The aircraft has a standard empty weight of 2710NaN0. 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 500NaN0 Rotax 503 engine.
The aircraft fuselage is an open frame made from bolted-together and gusseted aluminum tubing. Its 19.51NaN1 diameter two-bladed extruded aluminum rotor has a chord of 71NaN1 and employs a symmetrical airfoil. The transmission is constructed from a belt and chain mechanism. With its standard empty weight of 2710NaN0 and a gross weight of 4900NaN0, the useful load is 2190NaN0. Fuel tank capacity is, rendering a full-fuel payload of 1890NaN0.
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.
By January 2013 two examples had been registered in the United States with the Federal Aviation Administration.[4]
