 Aer Lualdi were appointed agents and licencees for Hiller in Italy, and the rotor system pioneered with the ES 53 became a feature of each of their subsequent designs. The first of thesewas the all-metal L.55, which introduced a fully-streamlined fuselage with stressed-skin tailboom and was powered by a 180hp Lycoming engine mounted in the nose and driving a rotor pylon which was carried in a housing in the centre of the cabin. Experience with the L.55 prototype led to construction of an improved model, designated the L.57. Engine: Lycoming O-360, 180 hp Seats: 2 |
