The IMAM Ro.5 was a sport aircraft designed by Alessandro Tonini and produced by IMAM in Italy in the late 1920s.

Design and development

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