[1] Of wooden construction, it has tailwheel undercarriage and 2+2 seating; as a development of Jodel aircraft, its wings feature the same distinctive marked outboard dihedral.

[1][3] To commercialise the concept, a DR100 prototype was then built at Dijon-Darois in 1959, followed by ten of the DR100A production model, initially for testing and feedback from local customers.

[4] Robin set up CEA, Centre Est Aéronatique, to manufacture the aircraft, and later on also subcontracted to SAN, Société Aéronautique Normande, in order to fulfil demand.

As a result, Pierre Robin wanted to win the next year's Sicily Air Race and further honed the design to create the Ambassadeur ‘Sicile’.

Slightly lighter and more streamlined it flew 10 km/h faster; Robin's plane winning the 1964 Sicily ‘Giro’ with ten Sicile-Records in the top twelve positions.
