Design and development

The Ro.5 was a conventional, parasol wing monoplane with fixed tailskid undercarriage and two open cockpits in tandem.[2] It proved popular with private owners and flying clubs, and was built in large numbers.[2] Some Ro.5s were purchased by the Regia Aeronautica for use as trainers and liaison aircraft.[2] A later version, the Ro.5bis, enclosed the cockpits under a long canopy.[2]
