A flying machine 1 comprises at least two motor driven, vertical axis, contra-rotating propellers 5, 7. A seat 15 and handlebars 21 may both be mounted on the machine 1 above the propellers 5, 7 at positions radially inward of the outer periphery of the propellers 5, 7 and/or a hub 33 may extend below the propellers 5, 7 and below the lowermost part of the machine 1. The handlebars 21 may be movably mounted on the machine 1 above the propellers 5, 7, movement of the handlebars 21, in use, controlling yaw of the machine and/or and collective pitch control of the propellers 5, 7. The machine 1 may comprise a yaw control mechanism such that a characteristic of one propeller 5 may be varied relative to the other 7 in order to induce a torque reaction to cause the machine 1 to yaw. |
