Clancy, I want to clarify my statement of owning the Stuntliner. There may have been others that I was not aware of. Mine was blue and red with the rows of painted windows on each side. The Fox 40 was upright and the cockpit windows were the openings for fresh air to the engine. I bought it from Jack after I saw it hanging up in Mike's Hobby Shop in Indianapolis. I swapped him for a small outboard motor I had.
The contest I flew it in was in Michigan. Big Art was there, perhaps judging. He saw it and immediately identified it as Jack's airplane, a fact I never refuted.
I sold it to a guy named Ron Graham who was in our flying club in Saginaw, Michigan. He never flew it. Sometime later, he died of a hot shot in a gas station rest room. I don't know what became of the Stuntliner.
How many Stuntliners Jack built, I have no idea. As far as I knew at the time, it was a one-off, like most of his models. In fact, I never saw him repeat a design as long as I lived there, although I can't say for sure. I moved to MI in 1968 and still kept in touch with Jack over the next few years. Every time I went back to visit my folks, I stopped in to see Jack.
You are welcome to check with Jack to see if he remembers the Stuntliner I got from him. Perhaps he could identify where it stood among any others he built.
BTW, the number of planes he designed I got the number 62 from his biography elsewhere on this site.
