Abstract
The subject invention relates to a launcher and one or more gliders for use therewith. The dihedral of the glider is achieved with two parallel creases that run front to back down the center of the glider. At the leading edge of the wing surfaces, self adhesive strips of flat magnetic sheet stock can be applied to the top and bottom of each wing to provide both proper weight to initiate desirable trim to the glider and to provide a force to separate the nested planes after launching, i.e., magnetic repulsion. For a multiple launch, the gliders are stacked on top of one another and placed upside down and mounted on a launching stick. Through use of a vertical upward force the gliders are launched with sufficient force so that wind resistance will induce the glider wings to collapse upon themselves, facilitating a higher launch. At the peak of the launch, the combination of magnetic repulsion and the spring back of the glider wings to their designed high glide ratio configuration, permits each glider to successfully separate and glide to earth.
