A flight control device is described for a flying object assembly. The assembly has a plurality of fins symmetrically disposed thereabout. Each of the fins is movable between a retracted position and an extended position. A support is provided for the flight control device. The flight control device further includes a frame for each fin which is connected to the fin by a pivot and is freely movable with respect to the support. The fin can be angularly displaced about the pivot. A main shaft is rotatably supported on the support and is coaxial with the axis about which the frame is movable. Also provided on the support, is a motor having a motor shaft. Included, are rotating means connecting the motor to rotate the main shaft. A guide is actuated by the main shaft and a follower which is carried by the fin engages the guide to angularly displace the fin about the pivot when the guide is actuated by the motor. In this way, the angular displacement of each of the fins can be controlled in the flight control device.
