Design and development

The Ca.66 was a well built wooden aircraft with ply venner and fabric covering, intended to carry out night bombing. The single-bay inverted sesquiplane wings were braced with streamlined struts and wires and were characterised by their squared off wing-tips, constant chord, and moderate 3° 30' dihedral on the lower mainplanes. The square section fuselage, rounded off at the nose, housed the four crew in three open cockpits with pilot and co-pilot side by side. At the aft end of the fuselage a large triangular fin, with rudder, supported the biplane tailplanes, which were also strut-braced. The tail-skid undercarriage had mainwheels on divided axles, strut-supported beneath the engines and attached to the lower longerons of the fuselage. Controls were conventional with elevators on upper and lower tailplanes, large horn-balanced rudder and horn balanced ailerons on the lower wings only.[1]

The Ca.67 was similar to the Caproni Ca.66 in overall design and span but differed in having 2 Lorraine-Dietrich 12Db engines and increased payload. Flight tests offered no real improvement in performance over the Ca.66, and the Regia Aeronautica did not order the aircraft into production.[1]


inverted sesquiplane bomber powered by four 200–220 hp (150–160 kW) SPA 6A engines in strut-supported tandem pair nacelles between the mainplanes; one built.
A Ca.66 powered by two 400 hp (300 kW) Lorraine-Dietrich 12Db (Isotta Fraschini 12Db?) engines in tractor nacelles mounted on the lower mainplanes; one built.
