The Ringmaster Sportster was the relatively unknown member of the Ringmaster family. It and the Ringmaster flash really didn't look a lot like the classic Ringmaster s-1 that is so well known. However , this Sterling model while probably not one of the largest selling members of the Rinmaster line still commands hefty prices when offered on the bay. Pat King undertook the preservation of this design and redrew the plans and has produced a limited number of short kits. This is the kit prototype. There is more about it on the Ringmaster forum. It is unusual in that it is one of the few side mounted full fuselage models in C/L.
