ABSTRACT:
A helicopter toy including a hollow body which forms an elongated conduit. A generally elongated planar tail member is secured to the body at one end of the body and is axially aligned with the body. The tail member also includes a generally planar flap secured thereto. The flap is generally horizontal and is arranged at any angle to the plane of the tail. A multi-bladed, boomerang-shaped propeller is rotatably secured to the body so that the body is suspended from the propeller. The toy may be thrown to describe a curved flight path, whereby the toy will return to the operator, or different flight patterns depending on the selected propeller. Air passes through the hollow body to continually keep the hollow body aligned with the path of flight of the toy.
