The Robin DR100 series is a family of French light aircraft made by Pierre Robin, which first flew in 1958. 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. Whilst no longer produced, plans can be purchased for amateur construction.
Design and development
The first aircraft of the line was the ‘Jodel-Robin’ of amateur construction, which was essentially a larger three-seater Bébé Jodel. It had the fuselage from a D11, and the wings from Jean Delemontez’s D10 project which were given to Pierre Robin. 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. The DR105A aircraft were fitted with air brakes. The later 1050 ‘Ambassadeur’ models further improved upon this design, cruising at 200 km/h for 19L/h fuel burn. 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. 790 were made in total: 331 by CEA and 459 by SAN; more have been made as homebuilts
Air races
In the 1961 Sicily Air Races, Ambassadeurs finished in 2nd, 11th, 13th, 14th and 15th places, and finished the 1962 Paris-Cannes race in all three podium positions. 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’. This improved design resulted in Pierre Robin's personal aircraft winning, and a total of seven Siciles in the top ten. The aircraft also finished first in the following year's Paris-Cannes
To celebrate this the design was further improved in 1963 and named the Sicile-Record. 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.
