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.[1]

Design and development

The DR1050 features a cantilever low-wing, a three-seat enclosed cockpit, fixed, tailwheel conventional landing gear with wheel pants and a single engine in tractor configuration.[1] 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 Avions Pierre Robin DR400 series (see Robin Aircraft).

The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 8.72 m (28.6 ft) span wing employs a NACA 23012 airfoil and has an area of 13.60 m2 (146.4 sq ft). The standard engine used is the 100 hp (75 kW) Continental O-200 four-stroke powerplant.[1][2]
