The Duruble Edelweiss is a light utility aircraft designed in France in the early 1960s and marketed for homebuilding. It is a low-wing cantilever monoplane with retractable tricycle undercarriage and all-metal construction. The aircraft was designed for a load factor of 9. Two- and four-seat versions were designed. The aircraft's creator, Roland Duruble flew the first example, a two-seater designated RD-02 in 1962, and in 1970 began to market plans for a stretched version with a rear bench seat as the RD-03. Over the next 15 years, 56 sets of plans had been sold, and at least nine Edelweisses finished and flown. In the 1980s, Duruble marketed an updated version of his original two-seater as the RD-02A, and sold around seven sets of plans, with at least one aircraft flying by 1985.
