RE: Bill Falck's Special
I've had the plans for it for a couple of years, but have not built it. Foster won the '67 Nats with it, then it was presented in Flying Models the next year. Following that, a glass and foam version was done by a couple of guys in Northern California, one of which was my old pylon racing buddy and mentor Jim Kelly. They were sold by K and K Industries, but often one or two would be sold into an area and then get splashed by the locals. So they got out of the kit business after a few years.
At that particular point in time, F1 models were much more scale than in the later years. Although the scale was about 2 5/8" to the foot, some deviation was made primarily in width of the fuselage. While the rules had a 7 " height, only 3.5" was required for the width. Converted to full size, this would have been a fuselage height of 32" which is realistic, but a width of only 16" or a bit thin for an adult male.
