The Jodel DR1050 Excellence and Ambassadeur are a family of French amateur-built aircraft, designed by Jean Délémontez (the principal designer of Jodel aircraft) in collaboration with Pierre Robin, as a development of the Jodel D.11. The aircraft was built in the 1960s both by Centre-Est Aeronautique (see Robin Aircraft) and by Société Aeronautique Normande but since the demise of the latter in 1968 has only been supplied as plans.
