Carlo Lualdi had previously used this rotor system in his experimental Lualdi-Tassotti ES 53 and with his new company now built a succession of more powerful helicopters incorporating the Rotor-Matic system with a gyro stabiliser of his own design. The L.55 and L.57 culminated in the L.59 which was selected for production by Macchi, but cancelled.
Aer Lualdi ceased to exist by 1964.
