I remember walking into a hobby shop in San Antonio , TX around 1992 or somewhere in that time frame, and as I went through the store I noticed that it had become dark around me as if the lights were going out. I looked up at the lights, but they were obscured by a Nosen P-51 Mustang! I have always wondered what became of Bud Nosen. You could say that he was ahead of his time, but it might be more accurate to say that he was ahead of the engine manufacturers of his time.
