This light attack/recon biplane was the first design produced in serie designed by Eduardo Barron in the mid/late-1920s. Obviously inspired by the Fokker C.IV, the R-I employed the same construction structure: wooden wings and steel tube fuselage, both fabric covered. Some of the thirty produced saw an utterly brief service (1926-27) in the Spanish Morocco, but the design proved to be barely satisfactory and they were mainly employed as trainers. They were swiftly retired from service in 1931. Loring had more luck with its replacement.
An imposing ugly duckling certainly.
