Fauvel AV.50
 The Fauvel AV.50 Lutin (English: Elf) (originally designated the AV.61) was a design for an unorthodox light aircraft produced in France in the 1970s. Like other designs by Charles Fauvel it was a tailless design with a reverse-delta wing. In this case it was a single-seater intended to be powered by a converted Volkswagen engine.
