This made the payload 20% of the maximum weight, compared to only 9% for the Ca.74G, which was heavier, smaller and inferior in performance.

The fuselage, of quadrangular cross-section, was made of steel tubes covered with fabric, as were the wings and tail.

It was initially fitted with the 149 kW (200 hp) Armstrong Siddeley Lynx engine, driving a two-bladed metal propeller 2.88 m (9.45 ft) in diameter.

It was fitted with an Alfa Romeo Jupiter in the nose, and an Armstrong Siddeley Lynx under each wing, giving it over 597 kW (800 hp) in total.

The ceiling was improved to 5,500 m (18,045 ft), but the greater drag and weight reduced the maximum speed to 205 km/h (127 mph), and the endurance to only six hours.

A further development was the Ca.102, with the original airframe, but only two Bristol Jupiter engines, fitted with four-blade propellers, delivering 746 kW (1,000 hp).

The removal of the engine in the nose made the aircraft more aerodynamic, improved visibility for the pilots, and allowed the fitting of four machine guns.

An interesting development was the Ca.102quarter, a four-engine variant, with two engines on each wing, one facing forwards, the other backwards, all with two-blade propellers.
