The invention provides a multi-flapping-wing aircraft and a flying control method thereof. The multi-flapping-wing aircraft comprises a rack and four independent flapping wing mechanisms which are mounted on the rack and have the same structures, wherein a landing gear is arranged below the rack. When the flapping-wing aircraft is parked on a horizontal plane, the bottom surface of the rack is parallel to the horizontal plane; the four independent flapping wing mechanisms are distributed at four corners of the rack in a leftward-rightward symmetric and forward-backward symmetric manner; and each flapping wing mechanism comprises a wing, a mover, a similarly I-shaped soft iron core, a coil, an edge-grooved wheel and a rubber ring. Swing motors are used for directly driving the wings to swing; no transmission mechanisms are arranged between the swing motors and the wings; and by changing the time for applying voltage to two electrodes of each swing motor, flying of the flapping-wing aircraft is controlled, so that the wing swinging frequency can be increased favorably, and the lift force is enhanced. The flapping wing mechanisms are high in swinging strength, long in service life and low in manufacturing cost.
