A control system for controlling a model vehicle on a long flexible rod which allows considerable freedom of motion of the vehicle. A hand held control unit has controls operated by both hands and by the thumbs, providing three double or two-way channels of control through cables extending along the rod. The rod is built in sections which plug together, the sections having graduated flexibility to provide the proper combination of support and freedom of movement. At the model, the cables are carried through a pivotal connection which ensures minimum change in cable length during maneuvers of the vehicle, and a spring incorporated in the connection maintains cable tension. The system is adaptable to a variety of surface travelling motorized vehicles and the rod arrangement allows competitive operation of several vehicles in close proximity.
