The Caproni Ca.100 Caproncino was the standard trainer aircraft of the Italian Air Force in the 1930s. Based on the de Havilland DH.60 Moth, the design extended the span of the lower wing to create an inverted sesquiplane configuration.
One example of the Ca.100Idro seaplane version was used to establish a world seaplane altitude record of 5,018 m (16,462 ft) in 1931.
The design was produced by Caproni's Bulgarian subsidiary as the KN-1 and under licence by the Peruvian government from 1935.
The Italian Air force museum at Vigna di Valle acquired an example of the type on 24 May 2007 now marked with the registration FIR-9, appropriate to a Ca.100 serving at the Florence basic Flying School in the mid-1930's.
