An unpiloted rotor-driven aircraft comprising a drive unit (5) having a drive motor connected via a rotor shaft (4) to a rotor member (1) for generating a substantially downwardly directed air stream, a load carrier (7) arranged below the drive unit (5) and connected thereto, and a control means (S) the angular movement of which is independent in relation to the load carrier (7) and which comprises a support member (21) provided with adjustable rudders (25) arranged to be influenced by the air stream generated by the rudder member (1) in order to control the movement of the craft, wherein the rotor shaft (4) comprises a lower rotor shaft (4a) and an upper rotor shaft (4b), which rotor shafts (4a, 4b) are articulately joined to each other by a first joint member (91) that permits limited angular movement between the lower rotor shaft (4a) and the upper rotor shaft (4b).
