This is a modified FPG-9 glider (Foam Plate Glider 9″). A smaller amount of foam is used for the nose of the glider, the penny is just taped below or above, instead of cutting a longer piece of foam and bending it back. This allows the leading edge of the glider to be use more of the foam plate material resulting in slightly larger wing area. The vertical fin is cut using the edge of the up raise in the plate as a guide for the curved portion of the vertical fin. I think it is a little easier to cut out than the original FPG-9. A local hobby shop had cut out a thousand of these gliders for their booth at a county fair and given them away to kids. The cleanup crew noticed that none of the gliders were in the trash.
