ABSTRACT:
A flying projectile toy having an individual flying unit that is connectable to an adjacent individual flying unit, or plurality of units, to form a combined structure. Each individual unit has a top wall with an off-center hole therein, sloped side walls extending downwards from the top wall and abutment wall extending directly downwards from the sloped side walls. The top wall, side walls, and abutment walls define the airfoil shape for the individual flying unit. To enhance the flight characteristics of the individual flying unit, the abutment walls have a greater thickness than the top wall and side walls, and stepped ridges are formed on the side walls.
