[1] Designed originally as a two-seat light aerobatic trainer the G.5 was a low-wing cantilever monoplane powered by a 135 hp (101 kW) Fiat A.70 radial piston engine.

[1] It had fixed tailwheel landing gear and tandem open cockpits for the instructor and pupil.

[1] The type was built in small numbers and was followed by a prototype G.5/2 with an inverted inline 140 hp (104 kW) Fiat A.60.

[1] A small number was also built of the final variant G.5bis which was fitted with a higher output 200 hp (149 kW) Fiat A.70 engine.

[1] One example of the G.5bis, registered I-BFFI, survived in civil ownership and operation until at least 1955[2] and is now preserved in a museum.
