The A-B Helicopters A/W 95 is an American helicopter, produced by A-B Helicopters in the form of plans for amateur construction. By 2012 the A-B Helicopters website had been taken down and plans are no longer available. The design was developed into the Vortech A/W 95 and plans for that version remain available from Vortech. Design and development The A/W 95 is a development of the Adams-Wilson Choppy, which the A/W designation acknowledges.

The transmission is constructed from a belt and chain mechanism. With its standard empty weight of and a gross weight of , the useful load is . Fuel tank capacity is , rendering a full-fuel payload of . 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.
