A flying machine comprises a chassis on the underside of which is mounted two vertical axis contra-rotating propellers, which share a common rotational axis. The propellers are driven by two motors through a common drive mechanism, the motors being mounted on the chassis above the propellers and being longitudinally spaced apart along the chassis. Handlebars are movably mounted on the chassis between a seat and a nose piece. A user of the machine thus sits substantially centrally on top of the propellers with their legs straddling the motors and drive mechanism, the riding position thus being closely similar to that of a motorbike. Various collective and cyclic blade pitch control mechanisms are also disclosed. The handlebars and seat in some embodiments are replaced by a load carrying region. |
