The invention discloses a flapping-wing micro aircraft with an 8-shaped wingtip track. The flapping-wing micro aircraft comprises a rack, a transmission system, a planar four-bar mechanism, a spatial four-bar mechanism, a motor frame, a wing mechanism, a supporting rod and an empennage mechanism. According to the invention, a single-motor driving mode is utilized, the required rotating speed is output by adopting two-stage speed reduction, the energy utilization rate is improved, an 8-shaped wingtip track similar to real birds and insects is realized by utilizing a plane four-bar mechanism and a space four-bar mechanism which are symmetrically arranged, and the motion stability of the flapping wing mechanism is improved while the relatively large flight lift force is achieved; output turning is achieved through the small gear bevel and the large gear bevel, and installation of all parts is facilitated; the empennage is controlled by the swing driver to move left and right, so that the structure is simplified, the efficiency is improved, and the aircraft can realize multi-degree-of-freedom flight; the whole flapping wing micro aircraft has the advantages of light weight, compact structure, high transmission efficiency, good aerodynamic performance, multiple flight attitudes and high bionic property.
