Oh Boy! I totally missed this one. Several years ago I was checking out Marvins Novi, and I noticed that the APC prop had been shortened, like in a ground scrape, as the ends were just a little rough. I asked Marvin about it, and he said it was working just right so he just kept using it. And the old Fox did run really sweet. After that, every time I saw the Novi, I just had to look to see if the same old short prop was on it, and sure enough, there she was. One of the times I was checking out his prop, he was wiping it down with fuel. I asked him why he did this, and he replied that that was a secret perfomance trick. I was standing there scratching my head trying to figure out how that worked when he got that sheepish grin and told me he was just cleaning the old oil off of it. Heck! I was about to go try it on mine, cause when Marvin speaks, I listen. Those of us that know Marvin and Rea, know just how fortunate we are. A really great modeler, a good friend, and a very nice couple.
