This study was to investigate the flapping-MAV that how to accurate that body movement relative to the signals to aerodynamic during flapping. And investigate the effect of the thrust, lift force and the wing beat frequency with the aspect ratio of wing span changing during eight-flight. Jigs and fixtures produced by the production of wire electrical discharge machining. Another starting point for considering the wings up and down position, the counter circuit is designed with a code to reach a precise positioning gear. Control program using National Instruments LabVIEW software, match data acquisition device, complete the development of automated test equipment. MAV experiments by different wind speed and voltage control, to complete a specific location on the aerodynamic body of the signal tag. The study also through LabVIEW software for image processing module, to complete the film's aspect ratio wing trajectory, preliminary inferences on the results of a eight-flight.
