One of his early fighter aircraft was the Ca.18 reconnaissance aircraft which was developed to the Ca.20, the latter incorporating a larger engine mounted under a stream-lined cowling, with shorter wings and fitted with a machine-gun for offensive operations. The Ca.20 developed in 1914 was described as an exceptional fighter and ahead of its time. It was a single-seat fighting scout of mid-wing monoplane configuration and had a fixed forward firing machine-gun above the propeller arc. Only one example was produced and for many years it was stored in Italy before being acquired by the Museum of Flight in Seattle in 1999, preserved and placed on display but keeping its original fabric covering.
