Watching this interview, and listening to him speak on the subject makes me want to start a project just so I can put a Corvair engine in it. Great interview!
Thank You! Yes... we started a yearly series called "ENGINE WEEK" to get more of the important details out to everyone building and Airplane and trying to make a decision on an engine. This is each year during the week of Thanksgiving. :-)
Class act right there. Much respect for this man. He don’t care to sell you a engine, he would rather teach you how to build your engine. I heard about him from my days building hot rods. He is a God to the Corvair car guys. Not sure if he build car engines, but I know many car guys call him for advice.. Great video Brian. Engine week was a great idea.
Mr. RR; thanks for the kind words. I have many friends among the land based Corvair engine builders, and pretty sure they just think of me as a colleague rather than a minor deity. Planes and race cars are different tasks, but I learned a lot from Corvair car guys over the years.
If every other component supplier in experimental aviation had half the knowledge, dedication and integrity of Mr. Wynne, it would be a very different landscape. The guy is a legend! And no, I don't own one of his engines.
Nice! You know what...its Thanksgiving Week. How about taking one extra step and CALLING William this week and sharing your thoughts verbally. HAPPY THANKSGIVING to you and yours! Thanks for chiming in and supporting your Aviation Family today!
I had a 1966 Corvair when I was working the line at two local airports. Each morning I'd have to drain the sumps of the 80/87 and 100 octane trucks. Right in my Corvair each would go. Also lubed it with Aeroshell. Finally traded it with 162,000 miles on it. Engine never had a problem, other than the darned pushrod seals.
Loving this series so far, but no one is going to beat this guy for truly being there for builders and the community. This was the second engine I almost bought and of the two the only one I regret that I didn't. Total class act, others should follow.
I've been flying a 3.0 Corvair in a Sonex since 2012. Great engine, excellent reliability, and the ohhh that sound! Thanks for the video and interview with William. There is a reason that he has been in the business a long time and is known as "the Corvair authority."
@Dale Williams Hey! Thanks for stopping by! Have seen you around on TH-cam and once in person at the Barnwell College. Nice airplane! And YES.... have even heard your near 200mph flyby's! Nice!
Been a Corvair fan for several decades now and always had the idea of mounting one of those engines in my home-built. W. Winn is a great resource and his attention to detail is unsurpassed.
My first car I had as a teenager was a 1964 Corvair. It was totally worn out and Dad and I rebuilt the engine. I'm sure nowhere near the standards you folks do but I learned a lot. It was a good car. I think it's so cool you folks are using Corvair engine in airplanes. The only thing that surprises me here is you're still using ignition points. I would never have considered that. But hey, if it works!
I really enjoyed watching this very informative video. When I was in public school we had the two speed automatic Corvair and my father put a bag of sand in the front trunk and that car was unstoppable and always RELIABLE ... I am in the Philippines now and looking to build a W.I.G. Craft and an affordable 100 HP high torque air cooled motor would suit my needs . I did not know there were so many variants to building the Corvair motor so It's time to visit your site to learn more.
Great one Bryan, I still love the sound of a direct drive aircraft engine. I had always thought that they the last bearing took the load on these engines. Great to find out this is not the case. I think a lot of builders are unaware of this fact so maybe your episode will educate builders just as it has me! I love the look of their engines too.
YES... this is all about education. Hope to provide enough of the deep important details so that a builder can make a good informed decision of which "platform" is best for him/her. This one offers the opportunity to learn how to not only Maintain... but Build the engine from the ground up. Thanks for watching! Good to see you showing up again! :-)
Great interview. I'm one of those builders that had a tight budget, and there is no way I could hop in my Zenith 650 and take off, without William's expertise. I love everything about my 2700cc Corvair. Super simple, direct drive, and easily maintained. I also plan on building another.
@Javier Lopez I have my Warp Drive prop adjusted for cruise, the 650 will climb out at around 900 fpm at gross of 1320 lbs. Cruise is about 125 mph at 5 gph, 135 at WOT and 6 gpm. If I set it for climb, it'll do 1500 fpm, and the mph numbers drop around 10 mph.
I really appreciate this series. I have been banging my head against the wall trying to decide what engine to put in my Zenith 750 Cruzer that I am building.
My dad had a gyrocopter with converted VW engine back in the seventies when a lot of the guys were using four cylinder drone engines for their gyrocopters .
That corvair engine was dead reliable, my mother had a 63 four-door and that thing was like a tractor in the snow, snow would be dragging the bottom of the car and it would be going right through it. Every once in awhile the turbine shaped fan on top fan belt will jump off and the light would go on and I will go with a pair of pliers and a screw driver and pop it back on and keep right on rolling. 👍
I had a Corvair back in 1972. I always thought it looked like an aircraft engine. They are fairly easy to work on. I suppose that you could use it on one of those air boats that use fan drive.
I wish the oil system was explained. I even see a dipstick. In unlevel flights how do you prevent oil from flooding the cylinders snd I see lines to the valve covers so are they run flooded in oil? Anything special with the push rod tubes an sealing? Interesting engine use. They have used Volkswagen egines too as I recall.
I just learned about advantages of the WW Corvair design I was not aware of. And they are substantial. I bet WW's phone is ringing today. Excellent subject powerplant today and an excellent interview! Am really looking forward to the rest of engine week.
I am seventy one and remember the air cooled Corvairs . Friend’s mother drove one and they were all over southern Cal back then . We’re does one even find these engines today? Are they still being produced or are they rebuilding old engines?
Loved my Corvair Spyder convertible, flew Sailplanes and modified 200hp super cubs at the time, always thought Corvair motor would be a decent aircraft motor.
A few questions. Cylinder head valve seat retention and excessively quick changes in temperature. Are you doing anything other than pilot technique to avoid problems? The fifth bearing. Is this a modification to the crankshaft or is it a bolt on to the output end of the crank? Are you using the basic 110 HP/164 CID head and have you a improvement for the obstructed ports. How is the gear life on the cam drive. Related issue have you had the output flange shear the key and move out of position on the crank? Are you using flat lifters and have you had to do things to insure proper break in with modern (no zink) oils? Have you considered port injection. I always had trouble getting even distribution of fuel between the cylinders?
I don't know a whole lot about aircraft engines so this might be a stupid question but why does it need such a high octane fuel what is the compression ratio of the motor. Does it have something to do with altitude?
Walter, I've flown them a long time ago, but it is a complex and expensive welding and machining operation, you lose cooling fin area, and it messes with the combustion chamber shape.
Also... The older Legacy Engines didn't have the technology available to them to provide a HOT SPARK with the mags so two spark sources were needed to better burn the fuel in the cylinder. Today's more modern High Energy Spark system allows for a "hotter spark." Also allowing spark gaps that don't lend themselves to fowling. Thanks for chiming in today!
Be sure to manage your expectations with anyone that doesn't have a flying prototype. Experimental aviation has seen a lot of unfulfilled promises. Especially in engines.
I believe I have. However... I am going to try and keep "ENGINE WEEK" about engines that are currently "In Production" - Legacy Engines that still have parts available - and most popular options. I might look into NEW TECH that is on the horizon as well. But... as others have mentioned you do need to be cautious with some of these because there is a lot of development need to become a "PRODUCT."
Mr. Wynne, With a metallic-substrate 3-D replicator, you could make ANY aircraft engine you desired, depending on the software and platen [base of replicator] -length. Want a JUMO 211 for a He-111 or Ju-87, or Ju-88?--a Merlin for Spitfires & many others? As it's NOT "wartime", make the DB605 for your Fiat G-55 out of alloy, instead of iron. You could put corvair heads on a custom-aluminum V-block. You could MAKE a straight-8 Argus for somebody's "Storch-resto". I'll bet if you "Made" one, Jay Leno'd buy a zero-miles straight-8 DOHC Duesenberg engine for whatever they'll bring, although with His 3-D replicator, maybe he already has a "spare." I like the idea of moding auto engines to become Aircraft power-plants. Maybe I missed-it--is the "rebuild-course", part of the monies you charge for the engine? If so, I think it's a great idea, as the new owner knows what's in the rebuild, because you showed him HOW to rebuild it, and He DID it! This should also nearly eliminate after-build/{--"incident"} lawsuits, making your "builds" cheaper. Thanks for your great Video
I hear that when properly cowled... you can use this as a pusher as well. Give William a call sometime... I am sure he would love to talk shop with you! Thanks for watching!
Darn.. I was hoping they used a gearbox to get the rpms on the engine up to utilize the potential HP of them. I want one for an airboat build. Gearbox that is..
No sir. Not at all. You can build these yourself. No inspections required. Or you can have a Builder Assist weekend with the parts supplier that converts these into Flight Engines.
That is a very good question. I am certain William would be willing to speak to you about that. Check the link above in the description to contact him. Thanks for taking the time to say hello here!
Haha! Nice! Thanks for watching here today. There is a link to his website in the description for this video. Feel free to call him and have a conversation. Tell him I sent yah!
@@ExperimentalAircraftChannel im just wondering if you can buy them from him or if you have to find the engine and convert it yourself. The latter of which I'd like to do.
@@sirtraineewhat576 You can do both! :-) William is very much a Teacher/Instructor and would prefer you learn your engine from top-to-bottom but he will also build you an engine if you prefer. Send him a message on his website. This link is above in the description. You can also find @WW Flycorvair on TH-cam and watch the videos he has created.
Spent time with WW and Sebastian Heintz together while volunteering at the Sun ‘n Fun radio station in 2008. Both were Just Us Folks guys. WW in this video said “uhh” more than 300 times. He doesn’t speak that way when Not on Camera. I cringed listening to this Interview (as a voice-over specialist before you, Bryan, were born). Editing out WW’s “Uhh’s” would have been a formidable task (but do-able). As Paul Bertorelli said in a January 2017 or 2018 AV Web video (quoting audio board Ops): Good Audio Makes Good Video.” Juss Sayin, fella.
The corvair hasn't caught on because it's not intuitive. William is knowledgeable but very difficult to follow. Other builders make it easier to navigate..

William Wynne is probably the most knowledgeable and honest engine builder in experimental aircraft today.
He has been around it for such a long time. And truly has a passion for it. I think that is what makes the difference.
Watching this interview, and listening to him speak on the subject makes me want to start a project just so I can put a Corvair engine in it. Great interview!

Interesting, and old fashioned, very much from a time when genuine service was the aim, glad to see there are still some providing it.
Classic Hot Rodding but in the Aviation format! :-) Thank You for watching!
I had a 1966 Corvair when I was working the line at two local airports. Each morning I'd have to drain the sumps of the 80/87 and 100 octane trucks. Right in my Corvair each would go. Also lubed it with Aeroshell. Finally traded it with 162,000 miles on it. Engine never had a problem, other than the darned pushrod seals.

XLNT insight into this subject :-)
Thank You! Thanks for taking the time to watch and also comment here.
Wonderful!
Thank You!
I don't know a whole lot about aircraft engines so this might be a stupid question but why does it need such a high octane fuel what is the compression ratio of the motor. Does it have something to do with altitude?
How reliable are these engines ? Would you fly a single from CA to Maui ?
Tremendous!
With more than 2 million Corvair car built, these engines are a good and economical alternative to Continental, Rotax, usw
A good comparison would be against the 6 cyl Jabiru also 3.3 liter.How they stack up costwise,power,weight etc.
All good points but there are real 6 and 8-cylinder aircraft engines are there not?
Very Kool!
Thank You! Thanks for taking the time to watch today!
Why not adding a 2nd plug on these engines? Not a hater, just interested.
Walter, I've flown them a long time ago, but it is a complex and expensive welding and machining operation, you lose cooling fin area, and it messes with the combustion chamber shape.

@@ExperimentalAircraftChannel Thanks for that info, it makes perfect sense.
Does your company have any training classes for A&P or LSRM mechanics?
Have you ever heard of the Gemini Diesel engine?

when they did not say the engine weight I quit watching
It is too bad there is not a good 150 to 180 hp option. The 120 hp engines are just not enough for serious aircraft.
Did anybody out there count how many times he said "ah" ?
Uhhhh
Great but very hard to listen to because of uhh ,uhh ,uhh , uhh , uhh, uhh, uhh ,uhh ,uhh !!!
