ABSTRACT:
A multi-winged flying toy includes a handle with a wing attachment at the upper end and a plurality of wings, each with a center hole for attachment. The attachment mechanism allows pivoting of the wings. The handle includes positioning and torque resisting formations for arranging the wings in a first position, where the wings are in alignment with one another, and a second flyable position. The handle has a centrally bored passage, and attachment shank having expanded width head, connected at its end opposite the head, to a tension mechanism located within the passage so as to maintain the shank tensed against the wings to retain the wings in first or second positions.
