This book describes and illustrates the development of the famous range of lightly-built and highly-manoeuverable Italian WWII fighters of the Reggiane factory, with their radial engines. These planes served with the Regia Aeronautica and other forces, including the Hungarian and Swedish air arms. This book describes the design, development and operations of this elegant and effective group of fighter aircraft. It features scale plans, photographs and drawings from wartime technical manuals, superb colour artwork of camouflage and markings and rare black and white archive photographs. Colour photographs of preserved aircraft illustrate all aspects of surviving airframes.
