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 Aéronautique Normande but since the demise of the latter in 1968 has only been supplied as plans.[2][3]

Design and development

The DR1050 features a cantilever low-wing, a three-seat enclosed cockpit, fixed, tailwheel conventional landing gear or with wheel pants and a single engine in tractor configuration. Tricycle landing gear is optional.[2][3]

The later DR1050M Sicile, manufactured by Centre-Est Aeronautique, featured a swept fixed fin with separate rudder in place of the earlier straight fin/rudder. This design was further developed as the DR200/220/250 series and subsequently as the Robin DR400 series.

The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its span wing employs a NACA 23012 airfoil and has an area of . The standard engine used is the Continental O-200 four-stroke powerplant.[2][3][4]
