Caproni Ca.100

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.

The Regia Aeronautica received two prototypes and 675 production Ca.100s, built by Bergamasche, Breda, C.N.A. and Macchi as well as Caproni.

30 of the Macchi-built examples were fitted with floats and designated Ca.100 Idro.

The Ca.100s were mostly used as primary trainers, though some undertook liaison work.

There were exports to Peru and Portugal.

The design was also produced by Caproni’s Bulgarian subsidiary as the KB-1 Peperuda .

Twelve Ca.100s “PR” (for Perú), a derivative with all-metal structure, powered by a 120 hp Kinner B-5 engine, were built under licence by the Peruvian government from 1937.

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.
