The Robin DR400 is a wooden sport monoplane, conceived by Pierre Robin and Jean Délémontez. The Robin DR400 first flew in 1972 and is still in production. It has a tricycle undercarriage, and can carry four people.

Development

The Robin DR300 series were developments of the earlier DR.221 Dauphin and DR.250 Capitaine with a tricycle landing gear. The first variant was the DR340 Major, a tricycle landing gear version of the DR250 Capitaine which first flew on 27 February 1968, followed on 21 March 1968 by the DR315 Petit Prince, a tricycle landing gear version of the DR221 Dauphin. The DR315 was later replaced by the DR300. In 1972 an improved version, the DR400 was introduced with a forward-sliding canopy.
