Abstract
A free flying aerodynamic toy that is manually launched and is composed of an elongate air foil having two identical surfaces that are joined to one another symmetrically of the longitudinal axis so that in response to rotation and translation through air, the surfaces sequentially cooperate with air flow thereover to produce lift. Circular stabilizer plates at opposite ends of the air foil produce vertical stability and have weighted peripheries to increase rotational inertia. Centrally of the air foil is a rib which divides the air foil into two symmetrical parts. The parts extend outward from the rib at a positive dihedral angle (an included angle less than 180.degree.) so as to enhance stability and reduce roll and yaw of the toy.
