From what I understand William is going to have one at Oshkosh and Roy is  also working on one and so is Dan I will try and find their site info for you.  Williams is www.flycorvair.com as you  probably know but I don't think he has much info on it as of yet and I don't  think any of them are for sale yet.

There are several Fifth bearing designs in the R&D stages.

I believe Dan is the first to fly one. He has about 20 hours on it I think.

I think Roy's design is the one I like the best so far.

I haven't seen Williams up close yet, but it looks interesting too.

I have one in mind that I want to try, we'll see how that turns out.

Cool List hey? all ya gotta do is ask

Dan's is www.fly5thbearing.com



Roy's is roysgarage.com



Roy has been refining his ideas and has my engine for conversion.

Dan I believe has 20+ hours on his.

It's flying on a "Cleanex"

A sonex airframe powered by a corvair.

In the CONTACT! Magazine Corvair Issue (#75, Pages 12 and 13), an article was written on the 5th Bearing offered by Falconaravia as plans and castings. I have not done any background research on this yet. Has anyone on the list any experience with this solution ?

Look for Huggins under the PARTS link

Mike,

I Have never seen one of those. In fact I have never even seen a picture of one. It seems to me that if they were serious about it they would at least post a picture of one built & on an engine. You might want to post that question to William, He might know something more about it.

You may be able to get more info from the seller, if you pursue it; I would be curious to know what you find out.

They mention castings so I am assuming that it would be similar to Dans setup. 

If you are interested in a fifth bearing set up; I would suggest you look at the setups that are being developed by the Corvair community. I say this because these people have a lot more invested in its success. After all, they are or will be flying them. If you are interested in what the Corvair community is doing check out the Corvaircraft list. http://mylist.net/listinfo/corvaircraft

I have a corvair engine with the numbers William Wynne calls for, and I have had it for about four years now. Now that I am ready to start building my engine I am reading about installing a fifth bearing. I also see there might be a new crank shaft available, 4340 billet.  My question is, how much more will his add to the cost of building a corvair engine? Are we starting to enter into the same price range as a used 0-200?

Yep,  BUT the 0-200 group doesn't hold a candle to this group of guys, there 

are some INTERESTING doods here.

Unless you have "connections" in the certified world, and many or most of us dont, by the time you get the starter, generator, mags, harnesses, sparkplugs and oil tank, plus a rebuildable core, your $10,000 overhauled O-200 quickly becomes as expensive as a new Jabiru or Rotax. I tried this route answering ads in Barnstormers.com. The cost of the MA3-SPA carb that WW recommends gives you a taste of how expensive the rest of an O-200 can be.

Gil,



I really don't have any idea what an O-200 costs used.

I have never looked because it was never an option I considered.



So let me start this by asking, can you get a rebuild able  O-200 for about $200? 

I would think not but you might get lucky.



Then we can look at the cost of rebuilding services and the parts associated with the rebuild.



I don't know what it costs to re do the heads & cylinders for the O-200 but I can say that for about $300 you can get a set of Corvair Cylinders mailed to you that are bored and honed. (that's all 6).

A set of MagVair forged pistons are only $450 And this includes the rings.

The New Billet 4340 Crankshafts are $1195.

I have no clue what a new Crankshaft for the O-200 costs but I would bet it's a bit more than that.



I guess my point is that your money goes farther on the Corvair than it will on the O-200. Sure you could spend the same amount of money on each engine and have two working engines but you would not have two apples to compare.



you could do the absolute minimum to make the O-200 run and spend $x?

But if you were to spend the same amount on a corvair it would go farther & you would have an engine that had many more mew parts on it and dare I say more reliable?



One place where the corvair really shines is the cost of up keep and when it comes time to over haul.

Building the initial engine up & converting it is far more expensive than the cost of an over haul.



for example: 

Replacing your spark plugs on the Corvair; 6x $2 = $12.

Available at your local auto parts store.

And so on..



Look at these associated costs as well and you will see the Corvair shines even brighter.

Not to mention the smoothness of the engine.

I have never her anyone accuse the O-200 as being smooth.

I'm no expert on engines, auto conversions, or certified. I really don't have any problems using converted engines such as a Corvair or VW. I don't like the idea of two stroke engines, or high revving four strokes that need some type of prop reduction. To me high RPM bring to mind additional wear and other problems associated with increased forces due to high speeds.  I know there are piston engines that run in excess 10 K for long periods of time, but I'm just not comfortable with an engine turning over three thousand RPM in my airplane.  I have seen 0-200 engines blow off a cylinder  in flight, so I am under no illusions that there is a perfect engine to turn a prop.  The use of a lower RPM direct drive engine is strictly my personal choice based on nothing but my gut feeling. I also am under no illusion that I can build any type of engine for a few hundred dollars, it just isn't in the cards. I am in my sixties, have been a PP for over thirty five years, with several hundred hours of PIC. I am looking to build a plane that will last me the rest of my flying days, so I want to get it right. What ever it cost, it cost, I just don't want to make a ten thousand dollar mistake. 



The Corvair engine looks like a good alternative to the other 100 HP engines out there. You say it is much smoother running that an 0-200, and less expensive to rebuild. I have no reason to doubt what you say. The addition of additional support that the fifth bearing will provide also makes a lot of sense to me. From what I have seen in different ads, you can purchase a mid time 0-200 for  around 10 thousand dollars. That should be good for around 1000 hours of flying time, shouldn't it?. What will a comparable Corvair engine cost and what will the operating cost be?

Gil,



For $10,000 I think you could have a fresh Corvair with a new crank and maybe also 5th bearing.



I am not entirely up on the 5th bearings but that would be my guess.

Hi Gil,



Just a quick note regarding the Corvair.  I've only got 25 hours on mine but 

it is so smooth that when I first flew it, I actually was running on only 5 

cylinders because of a spark plug wire that was left off and I never even 

noticed it during flight!  It runs even better when firing on all six 



As for maintenance, I haven't had any yet but I did have a Mooney with an 

O-360 (with only 150 hours on the engine) that required a new piston, rings, 

plus labor that ran me about $2500 (If I had done the install, the cost 

would have dropped to about $1200, although I couldn't have done it legally 

on the Mooney).  On my Corvair, I would be able to replace the piston, rings 

etc myself for about $100.  I just replaced all the plugs on my Corvair for 

under $12.  The Mooney would have been about $300!



I'm running without the 5th bearing and my cost was approx $8,000 for the 

engine.



Anyway, just a small comparison between a certified and an experimental 

engine.  Hope it helps.
