 Normally the model is flown in a circle and controlled by a pilot in the center holding a handle connected to two thin steel wires.The wires connect through the inboard wing tip of the plane to a mechanism that translates the handle movement to the aircraft elevator, allowing maneuvers to be performed along the aircraft pitch axis.The pilot will turn to follow the model going round, the convention being anti-clockwise for upright level flight

For the conventional control-line system, tension in the lines is required to provide control.
