Abstract
A kite simulating an actual flying thing such as a bird comprises a central body of light material and a pair of wings easily attached to and detached from the central body, each of the wings being provided with two projections orthogonal with respect to each other so that one is inserted into the body in a direction substantially traversing the longitudinal axis of the body and the other is inserted into the body in a direction substantially parallel to the longitudinal axis of the body for fixing the wing to the body. The skeleton of the wing is constructed of flexible material so that it flaps during its flying operation.
