Neat history! I really knew nothing about the prototype. I'm guessing you used something bigger than a scozzi fan on the full scale one...
Funny thing about this kit is that I had seen the ad in an old magazine, but NOBODY had ever seen an actual kit until I found this one, so nobody was sure if it had actually been released. I bet it flies well, all BV's stuff does. I know his own prototype flew, I saw some articles in some old mags.
Where did I get it? Hey, I'm the KING of vintage balsa! I have my sources. This one came from deep beneath Cheyenne Mountain! Top Secret!
Not sure what I will do with it yet. I am tempted to build it, it's a great piece of history, and I happen to have a turbax and OS46 sitting around. Swore I had sworn off DF models, but this may be an exception, I dunno.
