The pressure change can not exceed 15 psi and 15 psi is not anything to worry about when epoxy and wood container is considered in small voids of space.

The site is closed down for nonpayment so all you get is a short message that the guy doesn't pay his bills, I have no clue as to why, everyone has their own story. I did get into the site a while back and it had a good deal of information on the planes and I think it included the P-51. The site if you can still access it had the name of the guy that I guess holds all the plans and info and another guy that I e-mailed. He responded that he had ordered a set of plans never received them and it took a year to get his money back. War is listed in the Jan. issue of Kitplanes in the plansbuilt aircraft directory and lists a phone number 813-620-0631 / fax 813-621-4142. You can give it a try but I think I'd only pay for planes COD after I inspected them. The guy I contacted also said that he had heard that Replica Fighters was trying to buy the rights to WAR, maybe you could check with them, I can't find their E-mail address right now.

My gascolator is located on the lower passenger side firewall so I built an three sided(top, front and inboard side) alumnium box around the gascolater. The box is open on the bottom and uses a baffle-type seal where it fits against the cowling. Then I built a NASA vent into the side of my cowling that allows only cooling air into the gascolater box. This method does two things: (1) Isolates the engine compartment heat from the gascolater. (2) Insures that the gascolater has cooling air flow across it whenever the engine is running. No more problems with vapor lock..

My question is what is a good prop for the KR2S and O200 combination? I don't know who makes a good wooden prop and what diameter (56"?) and what pitch to get. I know some are flying now so any help from someone with experience will keep me out of the reinvent-the-wheel mode. I will have the engine in a couple of weeks. It is complete with engine instruments and Rand engine mount so installation should not be too long. I have the soob mounted but water and oil cooling hasn't been completed. I don't have the time to do the development work to insure that everything goes well with the Soob. My work gets me transferred all over the states and I am often hundreds of miles from the KR for months at a time. If all goes well with the O200, the soob will be for sale in a couple of months. It is an asian EA81 (truck) engine, direct drive flywheel/starter, homemade intake and exhaust manifolds, watercooled turbo and Holly 350 CFM carb with leaning block. The engine has been rebuilt with new rings, oil and water pumps, heads rebuilt, and all new bearings. The KR has been moved to Oklahoma City last weekend where I am working for the next three months or so. So far, the KR has five trips on the trailer totaling over 3000 miles.

My question is what is a good prop for >the KR2S and O200 combination? I don't know who makes a good wooden prop >and what diameter (56"?) and what pitch to get. In one of the older KR Newsletters (paper version), there was a writeup on the KR-100. It is a single place, about the weight of a light KR-2S and powered with an O-200. He used a Sterba 60x68. The claim was that it gave much better performance than a Props, Inc 57x71. Quoting: "It increased the climb by about 200 FPM and cruise by 5 MPH. The RPM spread between static and cruise is only 300 to 350 RPM (2500 static 2800+ cruise)" Stats on the KR100 are: empty 680+, gross 1000+, cruise 205 TAS at 10,000 and 2800 RPM. 1500 FPM at 140 MPH to 5000 ft. 1000 FPM at 140 5-9000 ft. That is what I am planning on when I get my first prop.

I guess I am not the Low-down dastardly person he made me out to be. I have received no flaming e-mails or even a response from William. Two days is a lot more time than William gave me to answer his direct email to me. Here are the time stamps from his post to the KRNet and a direct one to me: Subject: [kr-net] Re: Corvair prop hub Date: Mon., 31 Jan 2000 17:05:20 EST From: WilliamTCA@aol.com Reply-To: "KR-net users group" To: "KR-net users group" Subject: Prop hubs Date: Mon., 31 Jan 2000 17:59:02 EST From: WilliamTCA@aol.com To: dmullins@ici.net How could I reply to a message that was sent almost an hour after the post to the KRNet? I was concerned about the starter being too high to make a smooth transition of the cowling. So that's why I inquired about a longer prop hub from William. In William's post to the KRNet he said "Dave wanted me to make him an 8" long prop extension, which I refused to do because it would place excessive loads on the crank." Below is the response he e-mailed to me on the subject back in Oct.: Subject: Re: Corvair conversion Date: Sun, 3 Oct. 1999 21:21:21 EDT From: WilliamTCA@aol.com To: dmullins@ici.net Dave! How are you? I was hoping you might call or write. Had a good time speaking with you at the gathering? Your questions; I know from testing that there is not much to be gained by extending the hub. If you really want it would cost about $300 more and it would increase the load on the crank a lot. Were is the refusal? When I talked to Dan about it he also said it would put too much load on the crank so we dropped that idea. I said do what you think is best but mount the starter as low as possible and leave me enough room to get a cowling behind the spinner. The results can now be seen at: http://top.monad.net/~theparkers/dave/ William also said in an email to me after I found some discrepancies in his manual and ways he could improve on it. I also commented on his attending fly-ins without a running engine: Dave, Thanks for your comments. I am going to make a quick video of the engine operating so people can see it. Ill send you one when its done. More later, William Its been 4 months, no video! I have had a small number of inquiries about "My" hub. In someone's email (I will not name them) they wrote: > I ordered and paid for a Corvair/KR motor mount from William Wynne about 3 > months ago and he has not shipped it and has not answered my last 3 emails > asking about it. I am starting to wonder if I will ever get it.

Yes I am a large person, What you don't know is that I have already lost 50 lbs from the time I moved back from the Bahamas. I intend to be closer to 200 lbs by the time I am ready to fly my KR. Well my final words are to the people that "scoffed" at me in Kentucky.
