As I said, a dirty Bear is a fast Bear. At that time, Bear was both dirty and fast. In more recent years, Bear has been clean, and not as fast. Whatever Mel Gregor and company were doing back then was clearly not being done by their successors. Sure the plane is clean, but its not as fast. There must be a correlation there somewhere ;)Quote:

With all due respect his name was Mel Gregoire. Another friend that I miss. If you were a man in your thirties and you invited an old friend over for BBQ and he stole not only your wifes heart but your dogs heart as well and he just smiled at you and you knew it was okay then maybe you knew someone like Mel. We actually did build a very clean engine once, but it was down on power, but not from anything we'd done. We blew it up. I'm not sure if I should say any more about that, it might be another one of those topics BCIV is in a better position to speak about.Quote:

That's a nice picture of Bill Hickle. I was always envious, but not jealous, of his perfectly trimmed beard. Lots of 6' ladders too.Quote:

Boil-off was always a Dave deal, and on paper it makes sense. I liked Dave, I worked with Dave away from air racing, I went to Dave and Bonnies house a few times and met the ridgebacks. Dave was very smart and wanted to change the world quickly. Greg Shaw was very smart and wanted to change the world one piece at a time. You can't change three things at the same time and assume any improvement you got was because of one of the three. One thing at a time and measure the improvement. I miss Dave and I miss Greg, I learned a lot from both.Quote:

And indeed... at one point, it could be found at or around the Sander's facility. This was the prop that was planned to be used on "American Spirit", which was acquired by Mike Brown along with the first engine ultimately used on September Fury.
I have seen photos of this prop while it was at the Sander's shop. It's likely they had some idea to use it on the Sea Fury, though it was never implemented. Here it is attached to American Spirit:

That's an early P-3 Aeroproducts propeller in Daves back yard barn in the San Fernando Valley, I've been there and I've laid hands on that airplane. When the early C-130's and P-3's were introduced they had three blade props and controls from Aeroproducts. It didn't work well, the props and controls were great, getting four of them working together caused a harmonic resonance that fatigued the wing spars and started causing accidents when the wing spar would fail. So Hamilton Standard came in and developed a four blade prop with a synchrophaser and it seemed to work pretty good because there's still plenty flying all over the world. The blades on the Bearcat three blade were Hamilton Standard P-3, the hub is a Hamilton Standard Constellation deal. The prop in that picture is an Aeroproducts and there's nothing wrong with it, the only reason those props were not used was because you couldn't use them safely in a group of four, a single engine airplane wouldn't suffer those issues and would take advantage of all of the engineering that eventually got them built to power the C-130 and P-3. I've always wondered if Dave chose that prop to snub his nose at the Bearcat with the Hamilton Standard three blade he helped engineer. Oddly enough most of my conversations with Dave were in the "test bench room" at Cal-Prop who would still use him as a contractor to build some test benches or adapters.Quote:

The original Bearcat regulator was like Chicago pizza, it was kind of heavy but you could pick it up with one hand.
