Magni Gyro, based just outside of Milan, Italy, has been manufacturing gyros since the mid 1980's. The founder of the company is Vittorio Magni, who like so many others, got his first taste of gyro flying when he bought plans for and built a Bensen gyroplane. The year was 1967. Since then, Vittorio has developed a complete range of one and two-seat gyros. There are nearly 300 Magni gyros flying worldwide.

The Magni Autogyro factory is located in Besnate, Italy. Composite molds and rotor blades are made at the factory with many parts CNC-machined for accuracy and quality.

There are currently 3 models of the Magni autogyro being manufactured. Full production of the M-21 has not yet begun.
