Officine Ferroviarie Meridionali of Naples started up in 1923. In 1934 the Societa Anonima Industrie Aeronautiche Romeo took over their aeronautical division and was re-named Industrie Meccaniche Aeronautiche Meridionali in 1936. The ‘Ro’ suffix was applied to all IMAM aircraft designs.

IMAM Ro.1. IMAM’s first aircraft was a license built version of the Fokker CV. It was the workhorse of the Regia Aeronautica during the Ethiopian campaign. It was eventually replaced by the Ro.37. ItalianKits produced a 1/72 resin model of this aircraft, with nice decals and a mixture of white metal parts (of varying quality) and photo etch. Most, if not all, struts should however be replaced with more accurately scaled replacements, preferably brass "Strutz", due to the weight of the solid cast upper wing. Italiankits have a 1/48 RO.1 in the works. LF Models have released 2 injection moulded kits in 1/72, based on their Fokker CV.E kit. They are not bad and the lack of rigging will make for a relatively easy assembly.

IMAM Ro.10. Another licensed built Fokker (F.VIIb/3m) that was used by the Ala Littoria airline.
AZ Models nicely moulded 1/144th scale kit is definitely an interesting subject and Valom’s 1/72 F.VIIb/3m could be used as a basis for an IMAM Ro.10, but any markings will have to be home made.

IMAM Ro.37. A biplane observation aircraft that saw widespread use throughout WWII. Classic Airframe released two 1/48 kits of the Ro.37 and are both worth a look although the cockpit framing behind the pilots seat looks mis-shapen. Special Hobby plan to re-issue this model. Has also appeared in 1/72 scale under three different brands: Airmodel, Aviation USK & Azur.

IMAM Ro.37bis. A radial engined version of the aircraft described above. 1/72 kits are available via Airmodel and Azur and, if you can find one, the 1/48 scale model from Classic Airframe.

IMAM Ro.41. A neat, compact biplane that was originally built as a light weight fighter but, ultimately, became Italy's principal trainer. It was perfectly suited to this role, being easy to fly and highly aerobatic. Planet Models resin 1/72 kit is a little gem, with extremely fine trailing edges. Only a lack of good internal detail is a disappointment. Assembly is fairly straight forward, although a jig will need to be used to help align the upper wings. All struts can be replaced with Contrail strut for more accurate scale appearance. Decals are for one aircraft only, a camouflaged aircraft from the Sienna flying school. Model has spatted wheel parts only, despite the box illustration depicting the aircraft without them.

IMAM Ro.43. This is a floatplane version of the IMAM Ro.37bis, with a revised wing arrangement. Designed to be catapulted from the deck of Italy's principal Navy ships. Nearly all were aluminium dope overall, with recognition stripes on the upper surfaces of the wings. Recently available is the Special Hobby 1/48 kit which is the best kit to go for. The Pavla Ro.43, from their ‘Octopus’ range, is the best 1/72 kit and is a close match to the plans found in the Ali d'Italia book. Has also appeared as a 1/48 resin kit under the Lilium label?

IMAM Ro.44. This is essentially a single-seat fighter version of the Ro.43. Special Hobby have released a nicely done 1/48 kit. Pavla, through its nautical "Octopus" label, released an accurate limited-run injection kit in 1/72 scale and, with care, builds into a very nice model. Massimodels produced a 1/48th scale resin kit, but it is quite expensive and produced in very limited numbers. The parts are essentially the same as those found in the “Lilium” Ro.43 kit mentioned above.

IMAM Ro.51. A 1937 fighter prototype fitted with a FIAT A.74 radial engine and a fixed undercarriage. It had an usually small tailplane and proved to be a poor design. Converted to a floatplane plane but, again, did not see much further development. Omega Models have three 1/72 resin variants of this aircraft (fixed, retractable undercarriage & floatplane).

IMAM Ro.57. This was Italy's equivalent of RAF’s Westland ‘Whirlwind’. A fine twin-engined fighter aircraft that was bogged down by lengthy and wasteful development as a dive bomber, something it was ill-suited for. Special Hobby have released very good mixed-media injection moulded kits in both 1/72 and 1/48 scale. CMR produced a 1/72 resin kit, as did Museum. The best reference source for the Ro57 is Aerofan #74.

IMAM Ro.58. This is a follow up to the Ro.57, being another twin-engined fighter bomber powered by inlione D.Benz engines with a two-seat arrangement. Available from SEM Models as a 1/72 resin kit with brass undercarriage and a coloured instrument panel.

IMAM Ro.63. A rare foray into STOL, this aircraft was built in too few numbers to be of any significance.
Sem Models have produced a 1/72 resin kit of this aircraft. Aerofan #84 has an article on this aircraft.
