The air ship is developed by LaChLuVe and was captured this October at the Airship Regatta in Friedrichshafen, Germany. It uses the principals of locomotion to move and is remote controlled. The fish glides through the air propelled by a very natural looking swish of the tail, which also provides steering when holding it in place and gliding. The pectoral fins are servo actuated for additional control.
