<p>Rotary wing aircrafts comprises a fuselage having a rotor driving mast extending substantially vertically. A rotor comprising a plurality of rotors is mounted on the mast for at least feathering and flapping movement. The feathering hinge is offset radially outwardly from the axis of rotation. Further, the rotor blades have weights mounted on the outboard tip ends thereof. The arrangement provides a significantly improved controllability of the aircraft.</p> |
