Robin HR100

The Robin HR100 is a French four-seat light monoplane, designed by Chris Heintz and built by Avions Pierre Robin as metal-winged version of the Robin DR253 Regent.

Development
The prototype of the Robin HR100 was the prototype DR253 Regent which was rebuilt with metal wings and powered by a 180 hp (134 kW) Lycoming O-360 engine. It first flew on 3 April 1969 as the Robin HR100/180. The HR100 is a low-wing cantilever monoplane with a conventional cantilever tail unit and a fixed tricycle landing gear. A number of different variants were produced in the 1970s. From 1972 a high-powered improved version was produced as the HR100/285 with a 285 hp (213 kW) Continental Tiara 6-285B engine and retractable landing gear and airframe modifications. The French Air Force ordered a number of HR.100/250 aircraft in the mid 1970s and these were used for communications and other duties.

A two-seat trainer version was developed as the HR200, and a modified version with a lighter airframe and new fin and rudder was developed as the R1180 Aiglon in 1977.
