Design and development

The Swing is a conventionally laid out ultralight/LSA aircraft with a single engine and high wing. The composite parts are built using a vacuum technology producing a sandwich structure. The fuel tank, engine mount and lift struts use

Narrow near the tail, the fuselage increases in diameter to the cabin, placed under the wings. Cockpit width is . The cockpit features bulged, glazed doors to improve visibility and room.

Operational history

Swings were produced for the Czech market until around 1997. Eleven had been sold by the time it became available in the United States from 2007. Thirteen had been produced by mid-2010. Three appear on the European (excluding Russian) civil registers, all in the Czech Republic.
