Pitch control is achieved by tilting the rotor fore and aft, and roll control is by tilting the rotor laterally. The tilt of the rotor can be effected by utilizing a tilting hub (Cierva), a swashplate (Air & Space 18A), or servo-flaps. A rudder provides yaw control. On pusher configuration autogyros, the rudder is typically placed in the propeller slipstream to maximize yaw control at low airspeed (but not always, as seen in the McCulloch J-2, with twin rudders placed outboard of the propeller arc).[citation needed]
