W.Green, G.Swanborough The Complete Book of Fighters
R.E.P. C1 France
Confined through most of World War I to manufacture of aircraft under licence (eg, Voisin biplanes, Sopwith 1 1/2-Strutters, Caproni trimotors), the R.E.P. (Robert Esnault-Pelterie) concern completed a single-seat fighter of original design early in 1918. This, the R.E.P. C1, was a rather angular single-bay biplane of steel-tube construction with fabric skinning. Powered by a 250 hp Salmson (Canton-Unne) CU9Za engine, it placed emphasis on upward and forward view for the pilot, having an abbreviated cabane with the centre section cut away above the cockpit. Armament consisted of two asymmetrically-mounted, synchronised Vickers guns in the fuselage. Performance tests were flown at Villacoublay on 27 March and 11 April 1918, and, although the recorded figures were good for the power available, the design did not find favour.
