AJ, In answer to your question I haven't started on my Flying Fool yet, and it probably will be a while, as I have several projects to finish before I get into nostalgic projects.
Matt Kania designed the Super Clown while he was working for PDQ Products Co. (in Millville, New Jersey). The Super Clown was so successful that Sterling highered Matt away from PDQ to design a similar model which became the Ringmaster. So while the Ringmaster was far more popular then the Super Clown, the Ringmaster is actually a "clone" of the Super Clown. The Supper Clown has been accepted as recognised model to fly in the Fly-O-Thon, and I have flown mine numerous times in the for the Fly-O-Thon, both here in Tennessee, and in North Carolina.
