Charles Ligeti was a
Czechoslovakian industrial chemist with experience in mechanical engineering. He commenced design studies for a high-performance aircraft in the 1970s. He migrated to Australia in 1977 with design work then resuming in May 1983. Development included the building and testing of

configuration, with the sweptback foreplane and the high-mounted mainplane being connected at their wingtips by vertical fins. The pilot sits in a recumbent position in a streamlined nacelle. The engine is mounted at the rear and powers a three-bladed ducted fan. There is no empennage. The

Australian ANO 95-10 code for ultralight aircraft.
