Mail Sack, 10-31-12, Patrick Hoyt and Philosophy of landing gear

Friends, the latest from the mail sack……

On the completion of Patrick Hoyt’s 601XL, Wagabond builder Russ Mintkenbaugh writes:

“Congrats to the Corvair powered aircraft builders!, Nothing motivates me more to keep the progress on building my Wagabond with Corvair power than attending corvair colleges and seeing and hearing other builders accomplishments when they take to the sky. I commend you both!-Russ”


One more late addition to the Kevin Purtee story comes from builder Matt Keyes:

“Mr. Purtee,Thanks for a great article and a healthy dose of motivation. I’ve been putting this off for long enough while career and family building. Now my three-year old daughter is crazy for airplanes, so I hope this will become a father daughter project and something bigger over the years. Time to stop making excuses and start making memories! Thanks again. – Matt”


On landing gear story (with philosophy of building sub-plot):

Engineer, Corvair/Dragonfly builder and  CC#22 grad. Guy Bowen writes:

“He must be a Harley Hardtail fan…you should have moved the spring to the seat and welded the gear solid to the frame. Of course the plane would be a pretzel after the first takeoff or landing but at least the tires would look perpendicular to the ground for a while! The road cries no tear for those who must suffer for style.- Guy”

Truth be told, Bob’s M/C is a 1961 BMW frame with a VW type one in it, old school but not hard tail. A number of rigid gear planes have been built from PA-15 pipers to Steve Wolf’s Sampson. Piper was trying to save money, Wolf’s goal was never letting the gear have any negative camber for handling reasons. Your guess that this was a desire for a certain look, function be damned is on the money. I don’t argue with anyone on their choice of style when it doesn’t matter, but I don’t compromise on issues of engineering or function.-ww

Piet Pilot, 601XL/2700 builder, CC#3 host Oscar Zuniga writes:

“Now, that comment about the Texas Taildragger stung! I have a little over 30 hours in N5460Q, a C150/150 with the Texas Taildragger conversion and I don’t remember it having splayed legs. I took a lot of my early training in that airplane and I loved it. I’m going to have to dig out my old photos and see if it’s got the squats! And that idea about the spring in a tube- fabulous! Send that in to Doc and Dee for the BPA Newsletter! Now, to give an ‘amen’ to your closing comments about solitude, I can only say that some of the richest times in my life have been spent working alone in a hangar, on an airplane or engine. The airplane and the tools don’t care who you are or what letters you have after your name. They are at the same time teacher and student, doctor and patient, filler and drainer- and time in the hangar, for all the dirty and beat up it leaves you, also leaves you fulfilled, restored, and healed. Thanks for your candid thoughts on that.-OZ”

Builder Randy Cary shares:

“William, I have been following your Corvair journey for several years and at 65 have been bitten by the bug. I am having to reorder my life as in the past five years I lost everything that I spent a lifetime gathering. However, I have a wonderful wife, two great sons, good health, and a job that pays about one tenth of what I used to make. [ You might say that I rediscovered lifes’ priorities.] Needless to say life throws lots of different challenges in your way and you have to decide how you want to handle adversity. Your recent comments about your painful 2-3 year journey of discovery displays the result of realistic introspection and the courage to discuss it.

Having read a lot in my life, I have been drawn to your blog in part because I want to explore the world of the Corvair conversion process and learn how to tear down and rebuild an engine. However, the real attraction I have to your site is the content of your blogs. It is a rare treat to read honest thoughts and opinions mixed with philosophy that you have painfully accumulated over a lifetime.

I congratulate you on the courage to pursue your work with passion, honesty, and a directness that is rare in today’s’ world. Not only do you have a great talent to teach the gospel of Corvair, but also you have a real knack for writing as well. I look forward each day to your thoughts and enjoy sharing your journey. I hope to visit the Barnwell Corvair College for a day to meet you and see first hand the evidence of your talents. I would have signed up, but family obligations were in place and those come first.Thanks for allowing me an insight into your life. I look forward to meeting you.-Randy Cary”

Randy, there was a guy who we saw just about every year at Oshkosh. He politely advised me at least 4 times that I should just stick to the technical stuff in my writing, because most people just want to know part numbers and sources. He offered the honest addition that he “didn’t get” much of the other stuff, and he asked who I wrote it for. “Myself” I told him. I suggested he just read around the stuff. Years later I wrote a story called “Speaking of Courage”  (search Three Aviation Stories at the top of the page) Same guy wrote me a long letter saying that it had really hit a nerve, brought up thoughts of friends long gone whom he had loved dearly. Said it meant a lot to him and said the story”was there when I needed it.”-ww

Corvair/Sprint builder Joe Goldman writes:

“I think there is some east european Jew somewhere in your past. -Joe”

Joe, coming from you I understand this is both a compliment and a comment on writing subjects that would have appealed to Franz Kafka. literally your 1/4 right. In 1915 in Passaic NJ, an 16-year-old Jewish girl named Rita fell in love with a young Irish Catholic police officer named Michael who walked a beat in her neighborhood. Their secret love survived his deployment to the trenches of France, and a year recovering from his wounds. When they announced their engagement in 1920, both families disowned them. It only made them count on each other more. They had a very happy and devoted marriage. Children William and Eileen came along in 1925 and 1929. Rita was a very successful business woman and Michael became Chief of Police. Michael had a series of strokes related to war injuries starting 1953. They gradually robbed him of speech, mobility, thought, and then life. Rita cared for him at home herself until he passed away in 1960.

When I was born in 1962, Rita was my only grandparent still alive. She was very cultured, articulate and traveled. She had many close friends and was unusually devoted to her 6 grand children. She knew more about Jewish/Christian history traditions and faith than any other person I have ever met. when I was little she taught me philosophy lesson #1, ‘men plan, God laughs’  She had an external joyousness and her life apparently wanted for nothing. I was the youngest of the 6 and lived near by, and took care of her home, the same one she had lived in since 1921. Being an idiot teenager, I could not understand why my Grandmother gradually had longer and longer periods of being somber in her life. At a visit with her cardiologist, an up beat man closer in age to me than her, the doctor blurted out something I had almost said, and certainly thought countless times. “Rita you have everything! What more could you want?”  She turned to him and said in without emotion, “Just one more day on earth with my husband.” It was a quiet car ride back to the house.  She died in the following year, 1986. I have had the 25 years since to think about how children and grand children are no substitute for the person you wanted to share your whole life with.-ww

Corvair College #24……Last Call, Reg. Closing 10-29 at midnight


We are getting down to the wire on registration for Corvair College #24 in Barnwell SC.

The link to the registration is:

Our previous posts on College #24 contain all the detailed information on the event. you can read these posts by clicking on the title block “Events” in the header above.

If this is going to be your first College, I highly recommend that you read about all the previous ones at this link to our main Web page: 

Special note on registrations: The College has a required $79 fee to register. 100% of this money goes to our local host and is spent directly on the event to cover the meals, drinks and direct expenses like benches and lighting. All of P.F’s crew are volunteers, none of the money pays for anyones time. The learning and technical support at the College are “free”, as None of the tech staff, myself, Grace, Dan, Rachel, Vern, or Terry see any of the registration money. In fact we pay the same fee to register otherwise covering the food we eat and direct expenses would fall on our host. The only people we have traditionally exempted from the fee are the pilots of the Corvair powered planes flying in. (and some of them pay anyway)  95% of the people who attend colleges understand this system and are happy to comply.This is the 3rd College at Barnwell, P.F., who is the epitome of a fine Southern gentleman, would never make a public issue of the 5% of the people who compulsively must evade carrying their own share. I may have lived in the south for 27 years, but I am permanently excluded from Southern gentleman status by virtue of being raised in New Jersey, thus I have no problem giving the 5% a hard time on this. My father was born in Passaic NJ in ’25, my mother in Irvington NJ in ’27. One of them dislikes their governor the other is entertained by him. Here is what they agree on: Their Governor always acts like someone from NJ. Although I have had 27 years of trying not to be like that, I will channel my inner NJ on people who try to ‘beat the system’ on registering.

Above, Ray Fuenzalita at CC#23 holds the sign of the three rules of Colleges. My talented and beautiful wife Grace painted the sign above. We have few rules at the Colleges, but we always abide by them. We lay off the top two subjects of conversation (as they rarely bring people together) and the third is that we teach builders to avoid products from totalitarian police states noted for poor quality.

Since #24 will follow a national election by 72 hours, I am going to forewarn people, no kidding, I am going to have a zero tolerance for breaking rule #1. I have actually thrown two people out of colleges one from#8 and one from #11 for breaking this rule after two friendly warnings. Grace and I live in one of the few ‘battleground’ states. For the last months you can’t turn on a TV or radio, open your mailbox nor drive down the road without being bombarded by the most inane advertisements, all funded by PAC’s. I have had enough, and I am headed to the college to go have a good time with friends and be free of political trash.

601 builder/flyer Phil Maxson pointed out that he has never seen two people in a political discussion where one person suddenly says “You know, I have never thought of it that way, you sir have changed my mind.” It is the best commentary on this I have ever heard. For people who compulsively need to talk politics, take heart, Thanksgiving is right around the corner, and you can again fulfill the role of  curmudgeon uncle/old hippy for the rest of your family, but you will not get a chance at CC#24.

Patrick Hoyt, new Zenith 601XL, now flying, N-63PZ


 We heard last night that one of the best liked and most respected builders in the Corvair movement, Patrick Hoyt, changed his status from ‘builder’ to ‘builder & flyer’. Patrick has been hard at building for a number of years, but has always rounded out his aviation seasons by heading to events like Brodhead, Oshkosh and a College. His easy-going nature and travels made has made him one of the movements better known builders, and many people were glad to spread the news that Patrick had passed the milestone of his first flight.

Low-effort learning

Above is a picture of Patrick’s aircraft. It has a 650 canopy arrangement, but the airframe is a 601XLB.  The photo is from an article written for the experimenter by Corvair/Wagabond builder John Schmidt. The whole article can be seen at this link: John and Patrick are good friends and the story is written with the benefit of this perspective. It also recognizes the positive support Patrick enjoys from his wife Mary. Patrick’s plane has a 2700cc Corvair with a Dan bearing and all of our Gold system parts and installation components.

We are now entering our 9th year of Corvair powered Zeniths. Patrick’s plane is the 61st 601/650 to fly on Corvair power. After our personal 601 was the first in may 2004, It took 3 more years to get another four of them flying. Builders have their own pace, commitments and priorities and to see a large positive impact, you have to be in this for the long run. Patrick’s plane follows Jim Ballew’s 601 by only 3 weeks. Lately we have had new Corvair powered Zeniths taking to the sky at 15-20 day intervals.  I regard builders as friends, not just customers, and it is very rewarding to play a role in the achievement of an ever-increasing number of builders.

We received this note from Patrick last night:

“Hi William. I took N63PZ up for the first time today, shortly after sunrise. Other than being the experience of a lifetime, the actual flight was uneventful. Wonderful that we live in a country and in a time in history when this is even imaginable. To think that I built this airplane and the engine with my own two hands, along with the generosity and inspiration of so many others. Sure it took a few years, but I did it, and today I flew it. I really appreciate everything that you’ve shared over the years. I’ve learned a lot from you.

Thanks,Patrick Hoyt


Above, Gary Boothe on the left and Patrick Hoyt on the right point to their hometowns on a map at Brodhead in 2009. The golden rule of homebuilding is persistence pays. Both of these men just started flying their Corvair powered planes, Gary his Pietenpol and Patrick his Zenith. In the experimental aircraft industry as a whole, the completion rate is a pathetic 20%. Salesmen, promoters and many journalists try to bury this statistic, because they belive it is bad publicity. If pushed, the three groups above are very quick to lay the blame on builders themselves.

Our builders have a completion rate at least twice as high as the industry average. Why? because I know that the ‘blame the builder’ line is BS. The real reason why the rate is low is because our industry is focused on getting you to sign a check and buy something. That is their measure of success. Conversely, I am focused on getting people flying. These are two very different goals, and the first is never going to improve the completion rate, in fact it hurts it because neither a salesmen in search of a buyer of a journalist in search of an exciting story are likely to accurately describe the long term commitment that is the only path to success.

Both Gary and Patrick in the above photo spent many years building their planes. The strongest indictment of ‘blame the builder’ mentality is a simple one: The average life span on a new LLC formed in our industry, often positively reviewed in our press is 36-48 months to bankruptcy. If the average successful homebuilder takes longer than this to complete his plane, it is plain to see that the majority of our industry is focused on selling things, not supporting them.  What builders are slow to learn is that these LLC’s are designed to have this short lifespan. They are not forced into it by troubled times. The goal of the people who started them was to get all the easy money of kit sales without ever having to follow through with far less profitable long-term support. the LLC format allows them to walk away without any financial responsiblity. Often they will be back with another LLC in a year or less, and journalists who are oblivious or playing along with the system don’t make the connections for new builders.

Being a successful builder like Patrick and Gary requires you to avoid the pitfalls of our industry. Deciding to only work with people who are committed to long-term success, support, and the goal of your aircraft flying. We have been working with Corvair flight engines since 1989. I have had the privilege of playing a supporting role in the successful completion and flight of several hundred homebuilts. If you have dreams and persistence, we will be glad to play a long-term supporting role in your personal aviation sucess story.-ww

New die spring landing gear on a Pietenpol, 10 a.m.-4 p.m.


Last week I wrote a report of the weight & balance and performance of Bob Lester’s Pietenpol going from a 65 hp Lycoming to 100 Corvair ponies. Here are some photos of the conversion, and an important improvement Vern and I made in the plane at my hangar. Bob flew the plane over in the morning, we did the work, and he flew it home in the afternoon. In my book, this type of gear is an improvement over bungees. Bob had just replaced his bungees, but had a very hard time getting enough tension on them, so his plane sagged. Bungees have worked on a hundred thousand light aircraft, but here is a look at an alternative system that I have used for many years.


Above, Bob’s aircraft on the ramp in our front yard at 10 am. It is easy to see that the gear is splayed out terribly. The bottom of the fuselage at the front gear attach fitting was only 22″ off the ground. I was motivated to fix this for Bob first because it is dangerous due to poor handling and the potential for a prop strike. Bob isn’t a welder, and I didn’t want him to keep flying it until something happened, The plane did have safety cables under the bungees, but they turned out to be boat cable, something I wouldn’t trust. Beyond all this, aircraft that have the gear like this look as if they are massively overweight. I didn’t want anyone to come to the false conclusion that it was the additional weight of the electric start corvair that was doing this. The only light aircraft that has the gear like this is the ugly “Texas Taildragger” Cessna 150 STC’ed conversions. Besides, gross wheel camber like this reminds me of lowered Honda cars driven by teenagers with their underwear sticking out of their pants, booming rap songs and 4″ diameter mufflers with the exhaust tone of a flatulent elephant sitting in a mud puddle. If you compare this with the photos of the aircraft when it still had the Lycoming, keep in mind that Bob had tried to re-wrap the bungees in between the photos.

Above, on the welding bench in my hangar. The red part is the original bungee strut. Above it is the steel die spring and the tube that houses it. We cut the ends off the red part and grafted them on to the new tubes. The springs are available from A/C spruce for about $100. Their rating is 1200 pounds per inch. They are 1″ ID, 2″ OD, and 6″ long. the spring works in compression. The 2.25″ outer tube is fixed to landing gear frame at the top. The 1″ tube works as a plunger. It passes up the middle of the spring to a washer welded on it above the spring. When the plane lands, this strut elongates by compressing the spring. Many people have seen the reverse of this system with external springs with complex machines slots. I made that style for my Pietenpol in 1997. It required a mill and some precision work.  After making it I got a chance to see an aircraft that Bernard Pietenpol himself had built. It used this external tube system. Brilliant, just as you would expect from the patron saint of homebuilding. The tube method has no milling, has no high shear points, is self aligning because the two ends are free to rotate., and had obviously worked for a few decades. But be forwarned, if you choose to put this on your plane, you will still have a handful of people tell you it will never work. (take their photo and name down, send it in and we will all make fun of them together.)

Above, I trim the ends of the main tube square in the lathe before welding. This makes it easy to get a great vee notch for penetration on the end caps. The 1″ bit is sticking into the tube to keep it from going into low earth orbit if it get lose in the chuck. We trim the tube to 6.25″ overall. This length has a great harmonic”ringing” sound if you get the tool shape just so, it gives the feeling of the fillings in your teeth falling out.


Above, a 2,25″ heavy-duty washer gets welded on each end of the main tube. The hole in the middle of it has to be drilled for a slip fit on the 1″ tube. The first weld is done without the spring or 1″ tube in place.

Above shows the 2″ washers welded onto the 1″ tube.  The spring has to be inserted before assembly.

Above is a head on view of what Vern and I were working on curing.  Bobs plane flies great, but letting this go would not show well and potentially end up putting the word “Corvair” in an accident report some where. I have devoted more than 20 years of my professional life to Corvair powered planes. I am in this for the long run, and letting something like this go, even if it never broke, projects a poor image of the Corvair movement. Besides I have been friends with Bob for 13 years, and I want him to have a sharp-looking, safe plane.

Above, the spring is inserted into the tube, the plunger goes through it, and the top cap gets welded on the spring gets a slight compression to prevent it from being noisy. In a ground loop, this system goes metal to metal in compression, just like a bungee system does. The part in the vice grips is the top cap, with the fitting taken from the red strut and blasted clean and pre welded on. If I was building from scratch, I would use a rod end or a fork. (off the topic, but Irwin made vice grips in the USA for decades. Today they are made in China. This disgusts me. CEO’s that make decisions like that should have their citizenship revoked and be sent to China themselves, but then we would have to send the new president of the EAA to Mao Se Tung land also. He was the CEO who sent the Cessna 162 to China. Google his name and the words “60 minutes, CEO, fraudulent engineering degree” for a nice look at his integrity.)

Above, top cap being welded on. You could not gas weld this without hurting the spring inside, but it isn’t an issue for a tig welder.

Above, one side down, one to go. This is a significant drag reduction when you also consider the bungees bags. Heat and some oil are the enemies of the bungees. However, the steel spring would only consider getting baked and a fine mist of oil a form of  love and care.

To save people who live for worry, speculation and internet drama the hassle of thinking up their own troubling questions, I provide them the questions pre-made:     

Why does that long-haired, opinionated mechanic William Wynne think this system would even work? What makes him think springs are tough enough? Maybe they are no better than bungees. William’s thinking of selling kits to do this, so if he might make 25 cents, and doesn’t that mean we can’t trust him to give us an impartial review? Wouldn’t I be better off taking the advice of a guy on a Matronics list who has never flown nor built one of these? That guy wouldn’t ever write back with an unsubstantiated claim would he?

OK, look above. This is the underside of the hangar gang wagabond. I welded this gear up in 2004. It has flown many hours and landed at over 1600 pounds gross. It works well period. I am not a great pilot, but I was well schooled by two masters. The only time I have in my log book in any tricycle geared aircraft is a single 30 minute flight in a 1963 Cessna 150 in 1999. I went to the airport that day and my old school instructor said “There are some things you should do once in your life, but not speak of….Today you fly the Cessna one filthy.” It was hardly the trip to adult entertainment section of Bogota Colombia I first thought he was hinting at.

Seriously, I have flown a number of classic conventional geared aircraft to know what a well-engineered, well-behaved one feels like. A far better evaluation is that a number of super-skilled pilots flew both my Pietenpol and the Wagabond, and pronounced them to have excellent handling. How tough are the springs? The ones in the Wagabond gear are actually salvaged from my Pietenpol wreck in 2001. They worked for hundreds of hours in the Piet, got smashed into the ground at 15 or 20 G’s, were BBQ’ed by the plane burning to a cinder, laid in a rainy field for 6 months, and then I cleaned them off and saved them for the next project, which turned out to be the Wagabond in 2004. Until they invent the elastic asbestos bungee, you can’t claim a bungee is this tough. (actually someone will, but ignore them.) Bungees are date coded. and they are to be taken out of service every few years. It may creep you out, but steel springs will out live you.

Above, in the fitting process, we held the aircraft up with the hoist and telescoped the original tube bottom into the 1″ tube.  We tacked it with a mig welder and rolled it back and forth to have it settle. We checked every thing with levels, and actually cut the tacks on the right side twice. On the third try the plane sat perfectly level. The struts turned out to not be the same exact length because the original builder in the 1970’s didn’t make everything symmetrical. It takes a small error here to make the plane have a wing tip an inch lower on one side. In other planes this could be completely avoided by having adjustable rod ends or forks on the ends. When perfect, we pulled them back out and TIG welded them on the bench with the proper rosette welds. Graces’s Taylorcraft and our 1-26 sit on the front lawn in the background.

Above, the finished product at 4pm. Ugly and dangerous duckling transformed in 6 hours, including a lunch siesta. The new ride height is 26.5 inches under the fuse at the front fitting. While it looks tall, scratch built gear on a piet can be much taller. Look at Photos of my blue Piet and you will see that the gear was 30″ under the fuselage. This extra angle of attack available in the three-point attitude allows the plane to land far slower, and stop shorter. It also looks a lot better. If anyone says “but you will not be able to see over the nose.” suggest that they go ask the guy they paid for a conventional gear check out for a refund. Ask an old school instructor if looking over the nose in the flare is a “technique,” and he will probably slug you like Buzz Aldrin decking a conspiracy nut job.( )

Very important to handling, when the plane is empty and at rest, the tops of the tires should be slightly further apart than the bottoms. Only when the plane is actually taxing at full gross weight should the tires come close to vertical. When the plane lands, the gear, if it is steel leaf, steel coil, bungee or Aluminum, has spring rate, but no damping itself. All the damping comes from the action of scrubbing the tires from the orignal camber, through vertical and then a little bit further. This is a very powerful damping force, especially on pavement. If the tires start out as vertical, the system forfeits much of the available damping, and starts heading back to the original incorrect camber. I know arcane details like this because I spent 5.5 years of my life at Embry Riddle. (If I had only known that I could one day be president of the EAA with a fake engineering diploma for credentials, imagine how much time and money I could have saved.)

Above, Bob with his re-done aircraft. This is a radically different aircraft than it was a few months ago. It when from barely having a positive rate of climb with two people on a hot day to being able to climb 800 feet per minute at the same load and conditions. It now has safe and smart-looking gear that works correctly. The plane is 25 mph faster now on the top end. For reference, Bob is 5’7″ or so.

Above Grace, Chris Welsh, Terry and Vern stand at the edge of our lawn and the runway. They are watching Bobs test taxi and flight on the new gear. The plane looked so much better than it had a few hours before, I was filled with a sense of pride in the skills, understanding, tools and capability I had painstakingly worked for over the last two and a half decades.

If you have never met me, but read this and think that I am charmed with myself, you got it all wrong. I know countless humans who are better people than I. They are kinder, smarter, and harder working. I can’t sing nor dance, I learn slowly, and I can’t stand to hear my recorded voice nor see my image on film. If I was once handsome, all trace of it is gone along with my uncorrected eyesight. I can be a conversational bore, and I deeply wish I had given my parents more moments to be proud of me. At 50 I look back on my life with a very critical eye and stand on the far side of a very wide gulf from the heroes of my youth. Even our dog, impeccably honest and loyal as canines are, Loves Grace and only tolerates me.

Honest evaluation leads to harsh thoughts like this. I spend a lot of time alone and have long bouts of insomnia, which can lead to thinking about things excessively. But the secret I would like to share with anyone who at times feels the same way, is that I have a sanctuary where I am insulated from much of my self-criticism, and a have a front, where at 50, I am much better on than I thought possible in my youth. When I am building things with my hands in my shop, I rarely feel poor. Although I now need glasses to do any close work, and my hands have lost a lot of dexterity, I am a far better craftsman than I ever was in my youth. I am not a great craftsman, but over a very long time I have worked to develop these elements in my life, and I compete with no one except who I was last year. While all else fades, these things flourish. It is a gift I am most thankful for.

I was aware of this in my youth, but it did not come into focus until 1999, the worst year of my life. (getting burned  was 2001, but it was a picnic compared to ’99.)  Feeling dangerously low, I sought the council of a guy I knew. He had come back from such a year. He is an artist, working as an incredibly detailed wood carver. He tells me to forget everyone and everything else, go back to your tools and work with your hands. Give up your apartment, but never your hangar. Explore all the things you can’t forget, have stolen, give away or loose. At the moment, I was having a hard time picturing another week, and I asked him how long it took him. The thought with great care a slowly said “two, no really three..” I was jolted and blurted out “Three months?” he looked me in the eye and said “No. Years. It’s probably your only way out.” It turned out to be a painfully accurate prediction.

In the years since I have read letters or posts from many people in a tough spot, who have sold their project or tools. I often think their ship is sinking and they have just traded their life jacket for five more minutes on the deck. I have also met a number of successful builders who have said that when everything else in there lives was broken, they had a place of refuge in work and creation. Of the thousands of people I have met in aviation, these people are truely brothers, for we share the same salvation.

For these reasons, I can honestly say that the only time I allow myself to feel anything most people would call pride, is when I exercise my skill knowledge to make something good. Much of the time, this is far better in the company of Grace or friends like Vern. It’s not real often that I indulge myself for an hour and give in to being pleased with something. Maybe two or three times a year. Watching Bob’s plane fly away with the gear fixed was one of these moments. There was stuff to do, but instead we sat around outside and enjoyed the evening. -ww.

On the value of Corvair Colleges, 750/2850cc builder Gary Burdett writes:

“My Cray comment (in the last mail sack)was meant as humor of course, but to be serious for a moment, I have had two individuals in the last several months email me on the zenith site because they see that I am a 750 corvair builder. I tell them to get more info about a corvair in airplanes, go to a college if you can, buy manuals at least if you can’t , and go to both websites anyway and read as they both give as good a flavor about the corvair as you can get short of the two options above. And do it now, not later. There , that’s it for the seriousness, back to humor.”

Builder Bruce Culver writes:

“William, I missed CC#22 in Georgetown and was wondering if you are planning any other Corvair Colleges roughly in the Texas area in the near future. If not, I used to drive 1100 miles from Dallas to Jax to visit my brother…..Wow. (Of course I was a LOT younger in those days…..)”

Bruce, We have spoken to a number of builders in favor of a Texas or a Oklahoma College in 2013.  Arnold Holmes, host of #17, would like to do another in Central Florida, the weekend before sun n fun in April. We are pretty sure we are going to Chino CA in the spring and with PF Beck and Crew’s blessing back to Barnwell every November.-ww

Guest Writer: Pietenpol builder/flyer Kevin Purtee


Below is a tale of adventure, penned by Kevin Purtee. He is very well known in the Pietenpol community, and in the land of Corvairs he and his wife Shelley are best known as the hosts of Corvair College #22 in Texas. People who have met Kevin understand that he has a whole other life in a different branch of aviation, but here he focuses on his love of building and flying homebuilts. For anyone who has completed a plane, Kevin’s words will ring true. If you are still working on your first, read the story closely, it insightful and motivating.

I have long intended that this site, among other purposes, be a focal point for this type of story. When reading Kevin’s words, he is obviously covering a subject near to his heart. This type of essay is out of place on technical sites, and is not family oriented enough for magazines that only publish dumbed down, vanilla flavored, offensive to no one, copy. Here we have an appropriate place for real homebuilders to speak as they would in their own hangars. We have had a number of guest writers before, and I welcome more. The format here isn’t really a discussion group, but I would like it to have input from a number of people who are motivated to put in a few hours to write down thoughts that come from experience in building and flying Corvairs.-ww


Hi Folks – Here are a few of my thoughts on the joys of homebuilding and flying. 

I live for the small, slow end of aviation.  I’ve been working diligently all my adult life to create a retirement that provides the opportunity to build and fly little airplanes full time, or at least as full time as I  want.  I’m blessed to be able to fly at work, and it’s great, but what I REALLY want to do is spend my time building and flying little airplanes and hang out with people with the same interest.  I’m very proud to have successfully completed a plans-built airplane.

The Build

I distinctly remember my father making the comment when I was a child of 7 or 8 that people build airplanes in garages.  That notion has stuck with me.  I was trying to figure out what to build when the July 1992 Kitplanes showed up in the mailbox.  Jim Malley’s stunning Pietenpol was on the cover.  My at-the-time wife said, “That’s it!”  “What’s it?”  “That’s the airplane you’re going to build.”  Fair enough. 

I bought the plans, the newsletters, the Tony Bingelis books, the AC 43.13, and several other reference books.  I started cutting wood in February 1993.  The at-the-time wife wasn’t really wild about me flying an airplane I built myself, but she no doubt thought I’d never complete it.  She was wrong.  (Do y’all remember the “My ex-spouse wanted me to quit flying” T-shirts that William and Grace used to wear?)  I did complete the airplane, though I traded the spouse.  The one I have now is as much as part of the hobby as I am.  More on her later.  Anyway, this is me climbing in for the first flight on 19 September 2009, 16 years and 7 months after I started building.



The build took a long time – a classic plans-built project.  In fairness, there was a lot of other stuff going on.  I had a couple of major job changes and moves, I had multiple jobs at once, and frankly, I had other hobbies.  I was also out of the country for a few years.  Without all the distracters it was probably a six year build. 

I really like this photo.

While it took me more than 16 years to build the plane, I flew the tar out of it when it was finished.  In 2 years and 10 months (subtract 10 months for out of town training for work) I flew the airplane 340 hours.  That’s 170 hours a year in a Pietenpol that I built myself.  I flew the airplane back and forth from Austin, Texas to Brodhead/Oshkosh 2.5 times.  (Current spouse, Shelley, ground crewed on all but ½ of those trips.  Makes life a lot easier.)  There are Pietenpols that were started in 1992, finished in 1994, and haven’t flown anywhere near 340 hours.  I was making up for lost time.

The bottom line on building airplanes: you’ve got to go to the workshop and build.  Airplanes do not get built on the internet and they do not get built by watching TV.  I encourage you (and me!) to get out there and start making parts. 

The Motor

In 1999 I chose an engine.  I found William in the back of Sport Aviation.  Mr Pietenpol had used a Corvair so I felt like I was being true to the design, and William offered plans for a starter.  Perfect!  I tell people that I’ve been a customer and student of William’s since 1999, and we’ve become friends over the last 3 or 4 years.  What’s amazing is that William taught me how to effectively convert an automotive engine for use in an aircraft remotely, and I have a minimal mechanical background.  I used the GM manual, his Conversion Manual, and his website to successfully complete the motor.  I used to monitor the Corvair internet discussion group, but decided early on that since William was the only one actually building and flying these motors, and the only one gathering enough useful data to be valid, that I’d stick with him.  So far so good. 

Another unique and positive aspect of our relationship with William is that he gives us access to him and the other Corvair All-Stars for several days at a time via the Corvair Colleges.  The next one is coming up in November in South Carolina.  Shelley and I will be there.  If you want to learn about Corvairs for flight use, this is the venue.  Shelley and I hosted a College earlier this year and we had a blast.  I cannot emphasize this enough: Corvair Colleges are extremely helpful.

Kevin, William, Grace, Scoob-E, Shelley. 


The Joys of the Hobby  

I enjoy the pleasant aspects of flying.  I love flying on a crystal clear day with no wind and smooth air.  I love flying at 500 feet and looking around.  It brings me pure joy.  I also love traveling with friends for the $100 burger.  What a blast!

Matt, Pete, Kevin and The Law on one of our many flying adventures.

I also enjoy the challenging aspects of flying.  Crosswinds, weather, cold, all combine to keep things interesting.  Here I am bundled for winter flight.  (The dented wing was on an airplane we found at that little airport.)


I intentionally challenge myself with lots of takeoffs and landings in lots of varied conditions.  Good or bad, I like it when people comment on how windy it is when I walk into the FBO.  I like turning the motor off on final when I’ve got the runway made (ignition back on, hand ready at the starter). 

I love flying.

Trials and Tribulations

There are challenges in the hobby.


This is a picture of the most frustrating day of my life.  The left landing gear gave out at the 2010 Pietenpol fly-in at Brodhead.  I learned to weld on this airplane and in this case it showed.  It’s a tribute to the people in this hobby that we recovered so quickly from this event.  One of the local guys at Brodhead, Matt Smith, my hero, repaired the gear that day and I was flying the next day.  We subsequently took the airplane to Oshkosh and then back to Austin.  I made the permanent repair to the gear and went on to make several hundred more landings without the gear giving way.  My welding’s gotten better, by the way.

I am speaking of the airplane in the past tense because I wrecked her coming home from Brodhead this year.  There was water in the fuel.  As I was taking off from Brodhead the engine started losing power.  I tried to turn back to the airport and ended up in the classic stall-spin scenario.  The airplane and I were both damaged badly.  The way I describe it sounds simple, but there are several layers of subtlety that require a more thorough explanation.  If you want to talk to me about it please come to Corvair College 24 and I’ll spend all the time with you that you need.  If you absolutely just cannot make it to the College (a mistake), then e-mail me at

I told you that I love aviation.  The accident was 3 months ago and I was hurt badly.  Here’s a picture of me flying my friend’s Wichhawk a month ago.

And a picture of me working on the Wichhawk two weeks ago.


And a picture of me rebuilding the Piet 3 weeks after the accident.


By the way, I received medical clearance to start flying for my job last Friday.  The flight doc kept telling me not to rush it.  I’m not.  I’m ready to fly.  I proved my point this way: the last test was the flight doc telling me I had to drag him through the parking lot, up onto the building porch, and then into the exam room at the end of the hall.  The exercise was designed to prove I could pull people out of an aircraft in the event of an accident.  I pointed out that I could not drag him like that BEFORE the accident.  Fortunately, he had a tiny co-ed student shadowing him.  I asked if I could carry her instead of him.  He agreed.  I picked up this tiny young woman, ran through the parking lot, up the stairs, through the door, and down the hall into the exam room.  The entire flight medicine cadre for the organization was in the hall as I ran between them, laughing, with the young woman in my arms.  I think that single event convinced them that I was ready and fit to fly.

I bring all these items up to make one point: flying is fun.  I love to do it.  I will not stop doing it unless I’m incapacitated.  The accident was neither fun nor pleasant, but I know what happened, know what to fix in the future, and I’ll keep flying.  A lot of people build airplanes and then are afraid to fly them.  Got it.  It can be scary sometimes.  The only way to solve that, move on, and get better is to GO FLY!  I found one major aspect of my professional flying to be very difficult when I first started.  I vowed to get better at that aspect.  The only way to get better is to practice.  25 years into the process, I’ve developed a lot of skill in that flight mode, and I am, at best, a pilot of average abilities.   


Shelley in front.

William made a post about Claire Jeffko and her understanding of her late husband’s overwhelming need to fly.  I am fortunate in that I am married to someone very similar to Mrs. Jeffko.  Took me three tries, but I found her.  Here’s an example: Shelley rode with me in the ambulance from the site of the aircraft accident to the medevac helicopter.  One of the first things we talked about, literally, was rebuilding the Pietenpol.  She knows what this means to me.  Some of you may not be so blessed.  I’m sorry.  Ply your significant other with gifts, bring them to a Corvair College so we can charm them, and work on them yourselves. 

Here’s Shelley ironing fabric on the wing.  She rocks!


The Internet

Most of you already realize that the internet is a double-edged sword, particularly if you’re new to a subject.  The quality of information and advice ranges from wonderful to criminal, and it’s often hard to tell who has good advice.  The good news for the Corvair world is that William is here to offer large doses of truth based on experience.  He makes the point that he wants us to fly proven, reliable (boring) equipment.  Darn straight!  There’s enough experimenting going on without trying to convert a Corvair to a turbo-prop.

Log off and build.  When your airplane flies, you’ll get back on the list and find the same people arguing about the same things and that they haven’t finished anything.


What’s the point to all this blather?  Go build.  Go fly.  You’ll love it.

Mail Sack, 10-23-12. Love Story and other Topics


Here is a sampling of the mail. On the Ed and Claire Jeffko story:

Builder Harold Bickford writes:

“Certainly real love is not possessive but giving and honoring of another’s dreams,hopes and aspirations. Edi and I will celebrate our 41st anniversary in November and that journey has seen individual and shared endeavors. In all of those instances it was a matter of wanting each other to go forward and grow with rich experiences. We also succeeded in passing that on to our four children who now as adults continue in the same manner.

Our shared interest in flying and building is itself a continuation of lifelong plans that are finally finding expression. We will run with that and enjoy the experience of learning new skills, meeting new people and making new friendships.

That Claire and Ed could know flying and building as expressions of who they are makes for a great discovery. They also had the capacity to give each other freedom in that regard. That makes for a very powerful commentary about how vows are lived out. Thanks for sharing and inviting. –Harold”

Zenith 750 Builder Dan Glaze writes:

“William, I too love to fly,someone ask me once if I could remember the first time that I flew,I sure could, I was 4 years old and remember spreading my wings (arms) and circling the back yard watching my shadow on the ground, at that moment I became a pilot. corncobs with feathers stuck in them and thrown into the air,rubber-band powered balsa airplanes,then control line and radio control. followed with the U.S. Airforce and then 16 year in the Ohio Airnational Guard.12 years building B-1B bombers and C-17 transport aircraft, and now a Zenith 750. My wife has always understood that I needed to be airborne and has always been very supportive.My Corvair engine has been running since the college at Roys last summer. Barnwell will be my 7th college and the 3rd since my engine ran and my wife insists that I go again. she knows that I need this fellowship with like-minded people and is so supportive, after 35 happy years of marriage she is still behind me 100% even though she herself does not care to fly. I likewise support her in the things that she enjoys.A Successful marriage is a 2 way street. Happy wife, Happy life. Dan-o”

Builder Matt Lockwood writes:

“Blues skies and tailwinds, Ed.”


On the topic of You Tube Videos, Zenith 750/2850cc builder Gary Burdett writes:

“Since you got your new Cray XE6, you are spending much more time on the net it seems.You may have been better off as a trilobite . The videos do give a little eagerness to get done to those of us “almost there” though and we don’t have to spend hours surfing for a couple of good hits so maybe it’s working out. Thanks.”

Gary, The only thing Cray I have is some Robert Cray blues records from the 1980s.  I am still a trilobite in an ooze of simplicity. This blog is written in the wordpress format that allows a cave man like me to update it without the assistance of my super genius IQ-207 wife. Our Traditional website is actually written in straight HTML code, 100% by Grace. She can actually type a translation in HTML as fast as I can dictate words to her.  It took a lot longer to update the old site for this reason. I am covering a lot of ground on this site because we are heading into the home stretch before CC#24, which is the last event for 2012. A new guy attending this event will have a much more productive winter engine building season than a builder who postpones his first College until next season. Readership on this site has been picking up steady since Oshkosh and the Zenith open house, with a number of new arrivals since Contact issue #105 made it to subscribers. I want to get a good flow of information that gives these new arrivals a panoramic view of the Corvair movement.-ww


On the topic of Unicorns vs Ponies Builder Charlie Redditt writes:

“I’ve enjoyed showing the below to my two young daughters, hoping to inoculate them a bit against consumerism.

Just to say, our consumer cultural preference for unicorns extends to a lot of other stuff as well. What made the connection for me was the last quote, “because you see, the machine never really did exist. On my way this morning to get a 140 hp.-Charlie”


 On the topic of Cylinder head temps, Builder Jim Lobue writes:

“Always great to get practical tips and the reasons why. I was thinking about using the stock temp probe location, but everyone in aviation seems to use the spark plug, so that is how the sensors are designed.

I havent spoken to you in years. Yes, the Zenith project is way behind due to elder care issues, but not dead. Being active in EAA Chapter #96 keeps me motivated.-Jim”

Jim, taking care of the parents and family is a priority that we many of our builders write in about, something you have in common with at least 1/3 of the guys building a Corvairs. Planes are important, but family first. Glad to have you back in action.-ww


On the topic of Billet cranks made in the USA, Builder Rick Byrd writes:

“put very awesomely william”

Rick, Thank you. Dan Weseman brought over two of the brand new cranks the other night to use my press to install the gears. The cranks looked magnificent. The fact that these are made in the US, from 100% US made materials means a lot to me. I like to support every effort to have manufacturing and its employment return to the USA. In aviation, quality counts, and the people who are solely driven by the quick profit motive who want to sell Chinese junk to American aviators have no morals. This includes the CEO of Cessna, who outsourced the C-162 to China. It was revealed by 60 minutes that this same CEO has included a fraudulent Aerospace engineering degree in his resume for the last 15 years. Guess what board of directors he sits on today (EAA). Fortunately each of us runs our own engine building company, and we can set the standards instead of accepting what the morally bankrupt corporate ‘leadership’ would have us buy.-ww

Guest writer: Phil Maxson, flying a 3100cc Corvair in his 601XL


In this Guest Writer piece we hear from 601XLB builder and flyer Phil Maxson of NJ. Phil has been a stalwart supporter of Corvair power since he finished his 601 in our old hangar six and a half years ago.  Phil has recently had his insights on experimental flying published in Contact! magazine issue #105. Phil’s latest project is to fly Mike Robitaille’s 3100 in Phil’s airframe. This gives a good idea of the quality of people and quality of engines in the Corvair movement. I can hardly imagine two builders of another alternative engine who would install a friends engine in their airframe just to test fly it.

Mike’s 3100 cc Corvair likely one of the last to be built. in the last 3 years almost every builder interested in large displacement Corvairs has opted for our second generation big bore engine, the 3,000 cc. Thousands of hours have been, and will continue to be flown on 3100’s. They are good engines, but the have been superceded by our more recent work.

Above, I stand with Phil in his hangar in NJ in August. I was up visiting my parents and made sure I went out to Phil’s airport for a visit. Unlike the vast majority of aviation businesses, we make house calls. It keeps us in touch with rank and file homebuilders on their home environment. Phil is a native of West Virginia. I always tell him that Chuck Yeager is my second favorite aviator from WV.


On Saturday, I had one of my most enjoyable days flying I’ve had in very long time. It was the first flight in my plane using a new engine. I now have a 3100 Big Boy temporarily installed. Mike Robitaille and I are doing a test with his engine – and what a success it turned out to be! The plane and engine performed flawlessly. Mike did a good job putting it together. It looks nice and runs very nicely.

Mike and I have been collaborating on several projects over the past year, primarily using my hangar to try out some new things. Mike built this engine a couple of years ago and ran it at a previous Corvair College. It had about 2 hours for run time on a test stand prior to installing it on my airframe. For the past year or so, his engine was sitting in my hangar in a crate. We discussed ways to preserving it so it stayed in top condition until his Sonex kit is ready to fly. One day I made the off-hand comment that the best way to preserve it is to fly it, and the idea was hatched.

 When it was time for the annual inspection this year, we started the process of removing my 2700 and installing the Big Boy. I also took the opportunity to make some improvements: I installed 6 CHTs (instead of the two I had before), I upgraded my old oil system to the new gold system, installed a Van’s oil manifold to simplify the plumbing. I also installed an O2 sensor on each exhaust with air/fuel mixture gauge in the panel. When we did the weight and balance, the plane had lost 16 pounds. I think most of that came from eliminating the remote oil system with an older, larger oil filter. We ran several heat cycles of the engine on the ground and we also did several full-power, high-speed taxi trips down the runway. As our final test we ran it for a minute at full power with the tail tied to my wife’s truck.

After so much ground testing, by Saturday morning I was ready to fly! Mike wanted to be there (understandably) and couldn’t make it until 11:00. I was so eager that by the time he got there I had the detailed walk-around done and the plane was fueled and warmed up. Mike grabbed a hand-held radio and headed for the runway.

 The first thing I noticed was about a 100 RPM increase at the first part of the take-off run. It was definitely developing noticeably more thrust based on seat-of-the-pants feel. On climb out I was seeing about a 1000 fpm climb out without pushing it very hard, climbing at about 90 mph. At the top end I’m seeing about a 12 mph increase in speed at the top end, and about 200 RPM increase at full power. The top oil temperature I saw was about the same as on my old engine: about 208 degrees. The CHTs are about the same as I was seeing before, when you account for moving the CHT thermocouples to the top of the engine under the spark plugs. The highest temp I saw was 425 degrees on Cylinder 3. In general the center two cylinders were the hottest.

Mike and I are planning to fly it down to CC24 in a couple of weeks. I need to put on about 3 more hours of testing between now and then, and do a precautionary oil change at about 5 hours. Then we should be ready to go for the nice flight down to Barnwell. That is one of my favorite airports, and Corvair Colleges are one of my favorite events. I look forward to seeing everyone down there.

 Here is a link to a very first run of the engine a few weeks ago:

 Here is a link to a short video of the first flight:

Ed and Claire Jeffko, a love story.


I have exchanged a few emails with Claire Jeffko, and I asked her permission to share with you her letters about her husband Ed. I thought they are very moving letters. It made me think about how we all promise to cherish, love and support on our wedding day, but very few of us can say that we have always fulfilled our vows. Here is a letter from a woman who lived up to hers.

Above is a photo of Ed and Claire Jeffko. Among his many passions in flying, Ed was a Corvair guy. Last July Ed did not return from a flight in his Glasair over the Cascade mountains. It is very a rugged area, and the accident site has never been found. Many  spouses in the same position would regret their loved one ever flew. Not Claire. Her letter is the finest example of  how real love seeks to support the passions and dreams of a mate:

“William, Thank you for your kind response.  Ed loved everything about flying and I mean everything.  If he could have been a bird, he would’ve.  He flew with the wind and was the most up to date and careful pilot I
 have ever known.

 When I first met Ed over 33 years ago, he was flying a little Cessna
 150.  Green.  We flew every single day we could, which was often.
 After we got married, we had the 150 for about four more years.  Then
 he traded it for a D-4 Cat to work on our property.  Let me tell you,
 a pilot without a plane is a sorry situation.  I could only handle it
 for a year and then forced the issue to  buy another plane as he was
 driving me crazy!!!  So, we bought a Piper Cherokee which we still
 have.  The Piper turned Ed back into the man I knew and loved.  The
 man had to fly.  When the Glasair kit came out we fell in love with it
 and although it took more years than we wanted to complete the plane
 we finished and had it signed off about two years ago.  When our
 grandkids saw the Glasair they were not happy.  After all, we would
 lug all their bikes, trikes, and assorted stuff over the mountains for 23 years.   But, in the Glasair there were but two seats….Grandma and Grandpa seats. Certainly not grandchild friendly. I helped every inch of the way to build that plane and the N number was my birthday.  Flying the Glasair was as close to heaven as we could get, especially with the clear canopy. We essentially were flying our dream.

 And, so last July as he went to pick up one of our grandsons for the
 summer, Ed and the Glasair 743CA went down in the North Cascades,
 taking so many dreams with it.  However,  Ed was a pilot through and
 through and wherever he is, I know he is flying. – Claire

Claire also added:

“We may never find him. He and that plane were as one. But, I will search for him the rest of my life.”

If you go to a zoo and look at a tiger or a bear in a cage, you will often see them repetitively pacing in a trance. You don’t need to be insightful to understand that a wild animal in a cage looses it mind and all the elements of what made it fascinating in nature. All that remains is its body, and only the most ignorant observer thinks they are seeing the actual animal. On the other end, domesticated animals consider their pen home and are happiest with the security it seems to provide. In extreme cases they will return to, and stay in, their pen even when the barn is burning down.

Men with real value to their lives are neither wild animals nor fully domesticated ones. They have a full range of actions. Most men today have the domesticated end down pat. There are a lot of good aspects of this, but alone, it is unbalanced. Powerful forces of our society steer men to and reward them for becoming fully domesticated. There is no such general acceptance for the man who seeks to have his individual adventure, make his own path, reject the fears he was told to internalize.

Many spouses of both genders, meaning well, seek to protect and shield their mate, to prevent the possibility of any harm. Claire’s letter is the rejection of this. She understood that a large and integral part of the man she loved was a free bird. One can try to justify caging a bird by claiming to ‘protect’ him, but we know this only reduces one to being a warden, not a protector. Her letters speak of fulling and supporting all aspects of Ed’s life, all of his passions and facets. Her reward was 33 years with a full person, not half of one.

What makes aviators different? some one from outside of aviation would read Claire’s words as some type of accident story. People inside of aviation, people still committed to having full lives including adventure, read her words as a very moving love story. People outside of flying would only focus on Ed’s accident, and think of his ‘bad luck.’ Aviators, Ed included, would see just the reverse, that Ed was one lucky guy, because he obviously found the right person to share his life with.-ww

I encourage any one who wishes to share their thoughts on this to do so here. Ed was subscribed to this blog, and Claire will have a chance to read them.  If you wish the note to be privately sent to her directly, just include that in the subject line and I will take care of it.-ww


Corvair planes and projects on You Tube


Here is a sampling of videos of Corvair powered aircraft, projects, and events on you tube. I combed through the files to find them for builders because I have found that the search engine on you tube stinks, and the order that it returns entries makes no sense. For example, the first video has 33,000 views, yet it is about the 100th video listed on the search “corvair powered planes”, behind lots of things that have nothing to do with aircraft and have less than 200 views. To save builders the time, here are a few sorted links. Fair warning: don’t bother to read the comments, many of them will leave you wondering what percentage of people are mentally ill.  One video has us running a 3100 outside when it is 28F. There is a comment about how the engine was “smoking and overheating” because you can see people’s breath after the engine stops. Like wise, the first landing of the 701 has 41,000 views in this version, 100,000 in another. They are not corvair fans, it people who have never seen a stol plane land thinking it is crashing. I was there, the Zenith gear soaked up the landing, just as it was designed to. Don’t spend too much time watching, try to get some productive hours in the shop this weekend. Watching flying airplanes is motivational, but it’s not a substitute for making progress on your own.
