The Caproni Ca.100 was the standard trainer aircraft of the Regia Aeronautica in the 1930s. Large numbers of this tandem, two-seat, biplane were built, powered by different engines.[1]
The Ca.100 (nicknamed Caproncino, little Caproni), was based on the de Havilland DH.60 Moth, for which Caproni had a production licence. They revised the wings so that the upper wing was slightly smaller than the lower, and also redesigned the tailplane. Otherwise, its wings followed those of the Moth in having no sweep or stagger. It was a wooden-framed, fabric-covered single-engine aircraft with a square section fuselage built around four longerons, with tandem open cockpits. It had a fixed, conventional undercarriage. Fuel was carried, Moth style, in a streamlined tank on the centre section of the upper wing.[1] It first flew in late 1928, piloted by Domenico Antonini, at Milan-Taliedo.[2]
Ca.100s were powered by a variety of engines. The most common of these were the 85 kW (114 hp) Isotta Fraschini Asso 80R and the 108 kW (145 hp) Colombo S.63, both six-cylinder air-cooled inline engines, and the uncowled 63 kW (84 hp) Fiat A.50 and 104 kW (139 hp) A.54 seven-cylinder radials.[1][2] Other engines in the 60-100 kW (80-135 hp) range included the Walter NZ-85, Farini T.58, Fiat A.53, Fiat A.60 radials and the inline Colombo S.53, Cirrus Major, de Havilland Gipsy, de Havilland Gipsy Major engines.[2]
The Regia Aeronautica received two prototype and 675 production Ca.100s, built by Bergamasche, Breda, C.N.A. and Macchi as well as Caproni.[2][3] 30 of the Macchi-built examples were fitted with floats and designated Ca.100 Idro.[1] The Ca.100s were mostly used as primary trainers, though some undertook liaison work.[2]
Some aircraft were built as civilian tourers,[1] numbering at least eight.[2] Later they were joined on the Civil Register by retired ex-military machines.[2]
There were exports to Peru and Portugal.[1] Twelve Ca.100PRs, a derivative with all-metal structure, powered by a 125 hp (93 kW) Kinner B-5 radial engine were built under licence by Fábrica Nacional de Aviones Caproni Perú, a Peruvian subsidiary of Caproni from 1937.[4][5] The Ca.100PRs remained in service with the Peruvian air force until 1946, when the remaining four aircraft were transferred to the Peruvian Civil Aviation School, where they remained in use until 1956.[6]
Ca.100 was also produced by Caproni's Bulgarian subsidiary as the KB-1 Peperuda (butterfly), with seven aircraft powered by 120 hp (89 kW) Walter NZ 120 engines built in 1932, and a further two Bulgarian-built floatplanes donated to the Bulgarian government by Gianni Caproni.[7][1] They were phased out of Bulgarian service due to problems with the aircraft's wooden structures within two years.[8]
One example of the Ca.100 Idro seaplane version was used to establish a world seaplane altitude record of 5,324 m (17,467 ft) in 1931.[9]
The last flying original landplane Ca.100, I-ABMT is ex-military, MM55194. The Aero Club Como floatplane I-ABOU, ex-MM65156, has been rebuilt after a takeoff collision in 2006, flying again in September 2010. At least one replica also flies.[2][10]
The Italian Air Force Museum at Vigna di Valle acquired landplane I-GTAB in May 2007; it is now marked with the registration FIR-9, appropriate to a Ca.100 serving at the Florence basic Flying School in the mid-1930s.[11]
Floatplane ex-I-DISC and MM56237 is in the Museo dell'Aeronautica Gianni Caproni, Trento.[10]
Ex-I-BIZZ and MM56271 is in the Royal Saudi Air Force Museum.[2]
