They are a very tough little trainer as I know from experience that at the Moncton Flight School they were looped, rolled and spun, to excess. I personally have about twenty spin trips in the little bird. They will spin like a top. They were referred to as the Traumahawk at our social club. Instructors that did a half dozen trips of spins a day said that it took a while for their heart rate to settle down each and every time they spun this little critter. As a trainer however, they offered a very serious experience benefit to the student, you could not find a plane that would do a more violent descending turn spin if you went out looking. With enough altitude under you, it really is the kind of training that will not bite you, ( this is a perfectly balanced aerodynamic maneuver) and one that can give you a ton of confidence. I used to go out and do spins for fun in the early dawn over the local fishing boats, only to watch after recovery at the looks on the faces of the fishermen. I highly recommend the training.

Each bay of the spar should have a 'drain' or pressure relief hole about 3/16" in the rear web of plywood. Also, each vertical between bays should be drilled to allow cross ventilation between bays. I used a 1/8" for this, varnished the hole and later ran a toothpick thru to be sure they weren't plugged. Then I closed the spar with plywood.

Joining EAA is a personal thing, I've been a member since I was 12, so you know my personal opinion. There are a lot of disgruntled people out there, but you can't keep everybody happy. 2. Get with your local FAA office they will give you a package that outlines what needs to be done, i.e. receipts, photos, builders log and sign-offs. 3. Doing your own engine rebuild is also a personal issue, you are the only person that knows your limitations. My personal opinion is that if you can build an aircraft properly and have the proper tools that you should be able to do the engine. Read anything you can about building aircraft VW engines, talk to others that have gone down that road. Just remember there are some out there that are doing some pretty scary things, don't just go with one opinion, we all think our ideas are the best. 4. We aren't in Russia, you don't need official clearance but an UNDERSTANDING WIFE IS A MAJOR ASSETT.

Dave is a customer of mine who bought my conversion manual at the 99 gathering. He has taken my drawings to a machine shop near his home and had my copyrighted plans used to make hubs. I spoke to Daves Machinist Last night because Dave didn't answer my email. I explained the issue to him and he was mad that Dave put him in the position, and stated he had no idea that Dave was trying to market the hubs as "his." He said that he had all my drawings in his shop, and He has given me his word that he will not make any more for Dave other than the 2 he did. We spoke directly and I have no problem with the guy. I have sold plans with the understanding that I am willing to share all I know with anyone, and plenty of guys have made their own hubs from my plans, some guys have even made one for a buddy who had plans, this is OK. But someone thinking that they can take all my hard work and set themselves up in business is out of line...by a mile. I didn't invent the Corvair, and I am not the only guy who ever flew one. But everything in my manual and all the parts I sell are really the result of my own hard work and flight testing. I learned many things from people who came before me but, I probably have put more work into testing flying corvairs that everyone who came before me combined. Ask anyone who has met me or dealt with me, I know my stuff....by sheer hard work. If someone else did their own work and came up with their own stuff then more power to them, but what Dave is doing is wrong, period, and he knows it. 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, last night his machinist related that Dave made the same request, which he also refused.....If Dave had any experience here he would know better. My plane has 500 Corvair powered flight hours on it. I have built dozens of Corvair motors. I have driven the cars 150,000 miles and in most states. I am an A&P, have a degree in professional aeronautics, and teach labs at Embry riddle Aeronautical University I have been testing Corvair for 9 years, Countless hours on the test stand.... I have built many planes, including much of Jim Rahms V8 powered lancair 4P (Cover sport Aviation June '97) Dozens of planes are flying today with parts shaped by my own hands. My former partnership ASI, billed over $900,000 in labor on experimental aircraft all done under my direct supervision. I am lucky and I work hard. I have sacrificed a lot for my achievements, and I am glad to share what I have learned with anyone. But this doesn't mean setting your self up in business at my expense when you have done no work. I am an optimist and would like to think this whole thing is just a big lapse of judgment on Dave's part. If he had answered my email and Said so I would have dropped it. If Dave responds to this, and says as much, Then as far as I am concerned, its over, move on. I don't run the krnet, and Dave is obviously free to come on and say his piece, I welcome it. As you read this and think about the plane your building, consider this: Yes Ken Rand had bits and pieces of other designs in the KR, but it was truly unique and different then and now. And if he and his family were not rewarded for his and their work, there might not have been a KR for everyone to build. I would have stopped testing on the Corvair at $14,000 in 1995 if I had not had the income of the manual to continue. Trust me, I have spent almost all the sales on more R&D, traveling to flyins, and teaching....and lets not forget over $1000 a month on cell phone (call me at midnight, I will answer) The point is I give a lot back and share what I know because that's who I am. I wont stop being this way even if people try to rip off my work. I am here because I have made a lot of friends doing this and other than a few days like this, Its pure fun. Thanks for taking the time to read this and think about it. I want to be friends with everyone, and agreeing with me isn't a requirement, but listening and comunicating is.

What kind > of formula of CFM one chose's may save $1,500.00 off a carb you choose. If I read this correctly, you are saying that the formula that I gave earlier was incorrect. That was: ------ For a "street" carburetor, cfm=(rpm x displacement)/3456 (.85). For the 110 HP Corvair running at 3400 RPM with 164 cubic inches, that would be 137 CFM. For my 140HP 190 ci engine running at 3800 RPM, that would be 177 CFM. Having said that, a carb from an 0-200 or 0-235 should work just fine... ------ I believe you'll find that dividing by 3456, or dividing by 1728 and then dividing THAT by 2 will give you exactly the same number. The .85 is a typical volumetric efficiency, which I assume is the same thing as the "efficient flow losses" that you mention. In short, please read the message before you start nit picking my answers. And as for carb use, it's not too much of a stretch of the imagination to think that the carb that works great on a 100hp engine will probably work just fine on a similar 100 hp engine. I would doubt that anybody on this list would go out and plunk down the bucks for a brand new 0-200 carburetor, but that might not apply to you, so I deeply regret the suggestion. While we're on the subject, you recently posted: > Aeronautical Design Engineers use a simple aid 1 inch radius with 1 degree of > deflection equals 0.017 inch of total travel. Thus a 7 inch > chord aileron inboard end deflected 20 degrees equals 7 x 20 x 0.017 = > 2.48 inch trailing edge travel.Its a K>I>S>S> formula. That's great, but if you multiply those numbers out, you get 2.38, not 2.48.. I believe the correct answer is actually 2.43 inches of total travel, or 2.39" purely vertically. I didn't want to nit-pick such a minor deviation, and I realize that some people rely on "pat" formulas, rather than a knowledge of basic geometry, but now that we're on the subject.... If we have to watch every word we say here because somebody needs to show how much smarter he is than everybody else, there are many of us who will just quit bothering to post answers. And if you can't do basic algebra, I wouldn't be nit-picking other people's algebra. Oh, and by the way, it's "carburetor" and "respondent", rather than "carburator" and "respondant", for future reference. I guess this is one of those that I should have just deleted, but I thought a demonstration of nit-picking might be in order. Well, there went another 20 minutes of KR building time...

If the part is allowed to contract without restriction of a bolt hole going into bearing or similar bearing restriction, cracks would not occur.

I said they were "mine" in the sense that I paid for them. Not that I designed them or even made them. I never claimed to know more than William or anybody about the corvair. I offered to be a go between Dan Woodward and the KRNet people because Dan does not have internet access. Anyone that asked I gave them Dan's Info to call or they could email me with a message. Yes William, Dan looked over your drawings but said he would have to do something different. So the only similarity to William's hub is the corvair and SAE-1 bolt patterns. Which William has no claim to. I am not marketing these hubs hubs as my design or setting up a business. I am just informing others of another source for parts. And yes I did answer Williams email tonight as it just was posted today at 1:00am when I got home from work.

I just meant there was no requirement to join if you were building a homebuilt airplane. By all means join for at least a year and you will know if its for you. Also seek out your local EAA chapter and attend a meeting or two. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: Drilling Wing Spars From: Mike Mims Date: Mon, 31 Jan 2000 22:53:19 -0800 X-Message-Number: 25 TONY SOLDANO wrote: > > Hey guys I haven't been on the net to long but I've been > on long enough to know that the kr project is just like > any other project.I asked about drilling the wing spar > verticals because i've seen some guys do it on there kr's. > After checking the plans i found nothing about it.>>>> I never heard of this until about 5 years ago. I am willing to bet there are hundreds of KRs out there buzzing around that do not have spar "vent" holes. I think how this whole thing got started was people building their wings in such a way that each individual bay was air tight. When they got up to altitude the wing would deform (foam and glass would flex). Well then someone went on to do some investigating and found that the wooden high altitude bombers that were built in England during WW2 had vented spars because of suspected failure. Do the math, do you really think your spars are gonna blow apart at 10k feet? I don't but obviously some do. I didn't drill my vertical members but I did use a 1/8 drill bit and drilled holes in the plywood shear webs so each bay could vent. I don't think it was needed but I did it anyway. If it will make you feel better build yourself a spar cross section and then pump some air into it. Measure the pressure and mark when it fails. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: Drilling Wing Spars From: Michael Taglieri Date: Tue, 1 Feb 2000 02:46:02 -0500 X-Message-Number: 26 >Hey guys I haven't been on the net to long but I've been >on long enough to know that the kr project is just like >any other project.I asked about drilling the wing spar >verticals because i've seen some guys do it on there kr's. >After checking the plans i found nothing about it.Most >of the time when doing a project like this one people get >carried away with mods and precautionary measures.From past >experience i'ved learned to keep things as simple and as >close to plans as possible. No offense, but that's completely wrong in this case. The KR is NOT "like any other project" because the designer died before the plans were anywhere near finished, and very few changes were made after that. Therefore, several gross errors still exist in the plans, and some very important safety modifications swere never put there. It is actually the plans PLUS all the old Newsletters that actually tell you what you need to do on this plane. I know that some of the guys here may go overboard in modifying the design, but the basic things they all agree on are things you should do. In particular, if there's no opening in the wing cavities, the pressure inside could make the fiberglass bloat up off the wing structure at very high altitudes, which could make it a very exciting flight.
