The Volmer VJ-22 Sportsman is an American homebuilt amphibious aircraft. The Sportsman is a two-seat high-winged monoplane of wood and fabric construction, with over 100 built by 1993.


Development and design

In 1957, Volmer Jenson, a successful designer of sailplanes, designed a two seat amphibious aircraft, the VJ-22,[1] The new aircraft, at first called the Chubasco, made its first flight on 22 December 1958.[2] The VJ-22 is a high-wnged monoplane, using the wings from an Aeronca Champion or Chief, with a new flying boat hull of mahogany plywood, waterproofed with fiberglass cloth. The aircraft's single engine, normally a pusher of between 85 hp (63 kW) and 100 hp (75 kW), is mounted on pylons above the wing centre section. A retracable tailwheel undercarriage is provided. The pilot and passenger sit side-by-side under an enclosed canopy, and are provided with dual controls.[1][2]

Operational history

While Jenson attempted unsuccessfully to get the Sportsman built commercially, plans of the VJ-22 were made available to amateur builders,[2] with 889 plans sold and over 100 completed by 1993.[3]
