ABSTRACT:
A flying toy (10) having an airfoil member (12), is described. The airfoil member includes opposed ends (16) with slats (14) extending therebetween. The opposed ends are connected to an annular outer ring (22) comprised of hollow tubing (24). The slats have first and second ends (14A and 14B) which are mounted to the opposed ends of the airfoil member 12. The center portion (14C) of the slats 14 are arced either above or below the plane A formed by the opposed ends of the airfoil member. The arced slats allow air to flow through and over the airfoil member 12 of the toy which enables the toy to fly straight and to stay in flight for a longer distance. The airfoil member is also able to be used without the annular ring to form an alternate embodiment of the toy 100.
