Robin HR100

The Robin HR100 is a French four-seat light monoplane designed by Chris Heintz and built by Avions Pierre Robin as a metal-winged version of the Robin DR253 Regent. Its prototype was the DR253 prototype rebuilt with metal wings and a 180 hp Lycoming O-360 engine, and it first flew as the HR100/180 on 3 April 1969. It is a low-wing cantilever monoplane with a conventional tail unit and a fixed tricycle landing gear, and from 1972 the improved HR100/285 added a 285 hp Continental Tiara engine and retractable landing gear. Variants include the HR100/200B Royal and HR100/210 Safari, of which 113 were built together, and the retractable-gear HR100/250TR and HR100/285TR Tiara. The French Air Force ordered a number of HR100/250 aircraft in the mid 1970s for communications and other duties. A two-seat trainer version became the HR200, and a lighter version the R1180 Aiglon.
