  • Patent number: 4153243
    Abstract: A remote control device for a model airplane including a mast, a rotary bracket, a yoke member projecting upward from and rotatable with the bracket, and a guide arm having its proximal end journaled in said yoke member for swinging movement through a complete arc of at least 180.degree.. Control lines connected to a model airplane are guided along the guide arm and terminate in a vertical carrier reciprocably mounted on a track on the rotary bracket. The carrier is moved by a remotely controlled actuator to alternate the linear movements of the control lines. The model airplane may thus be controlled to perform almost unlimited maneuvers, including overhead maneuvers and "wing-overs" in addition to the normal circling movement around the mast at different altitudes.
