The Manzolini Libellula was a 1950s Italian co-axial twin-rotor helicopter designed by Ettore Manzolini. "Libellula" is the Italian word for "Dragonfly".
Ettore Manzolini established a company in Rome, Italy to develop a helicopter he had designed. The design was the Manzolini Libellula an unusual co-axial helicopter. The co-axial arrangement eliminating the need for an anti-torque rotor allowed the helicopter to have a twin fin arrangement. The Libellula (Registered I-MANZ) first flew on 7 January 1952. An improved version was the single-seat Libellula II which went on to gain Italian certification on 15 October 1962. A three-seater version (the Libellula III) was built and a four-seat Libellula IV was planned but Manzolini stopped development in the late 1960s.
