Frank still has the plane. It actually has been stored in a barn, of sorts. Frank has a building on his property, formerly a barn, that has been converted as a toy building. He has his model stuff, a two place Hyper Lite airplane, and other assorted junk stashed away in there. I was out there yesterday and asked to take a photo or two of the model. I guess I will become its caretaker. I couldn't bring it home because it wouldn't fit in my Harley sidecar. Frank said he would get it to me.
As for my original, it's long gone. Many years ago I was flying it at one of Sam Wright's contests at Columbus and managed to do a genuine stall - spin - crash maneuver. There wasn't anything left worth salvaging.
The magazine article was published in 1972.
P.S. Frank has enough land for a 60 x 1000 ft main runway and an intersecting 600 ft runway so he can fly the real planes just by walking out his back door.
I love this stuff.
