Thought for the day:

Oshkosh and Brodhead, 2018

Builders:

We are less than 2 weeks away from two summer events: Oshkosh, the worlds largest airshow, and Brodhead, the epitome of grass roots aviation. I will be at both events. Although they are a once a year opportunity to see a number old friends, my primary mission is to meet builders, both in progress and just getting started, and answer their questions on the Corvair.

.

Although they are busy events, I put a serious effort into personally speaking with as many builders as possible. You will not find anyone in industry who mans their booth at Oshkosh earlier, nor stays later in the evening than I do. Many people regard it as a 9-5 event, but I’m frequently on hand from 7am-12PM. If you stop by the booth with a question, and find me speaking with someone else, please know that it isn’t rude to walk up and introduce yourself. I have no old friend nor industry professional who’s conversation is more important than than the most basic builder question. I am traveling  1,300 miles to get to Oshkosh in a 32 year old truck, I pay several thousand dollars year in advance for the space, and my mission is to speak with builders. If you have questions, please ask them, otherwise I’m just traveling a very long way with a lot of stuff to get a very expensive sunburn. Let’s make it count for both of us.

Location: my booth is “#616 in the North Aircraft Display area. This is the same place where it has been for a decade. It is right across from Zenith Aircraft, and 100′ from Van’s Aircraft. If you need rough directions, it is right adjacent to the Warbirds area. If you are looking in the book, I’m listed under the “F’s” to FlyCorvair.Com. My Forums can be found by searching “Corvair” or William Wynne”. 

.

Friday, July 20th: Set up at Oshkosh:

I’m planning on arriving at Oshkosh around noon on this day. I’m meeting Terry Hand at the site, and unpacking my trailer and setting up the tent and the booth, If anyone is inclined to assist, it will be much appreciated. Because 1,300 miles in an old truck without air-conditioning isn’t a enough itself, I’m spending 4 hours just before I depart Florida having two root canals. You can question my sanity, but not my commitment to aviation.

.

Saturday July 21: Visit to Brodhead:

Terry and I will head down to Brodhead either Late Friday night or very early Saturday. I am speaking in the afternoon before dinner, but I will be on the grounds and available to speak with any builder present. I will be very glad to look at any part or core motor any builder brings. I have spoken with the Pilots of several Corvair powered Pietenpol’s who will be at Brodhead. If you like grass roots aviation, don’t miss it. It is a non-commercial event put on very professionally by the local EAA Chapter. There is no admission, it is very friendly and low key. If you are bringing a child, or just someone acting like one, keep in mind that Brodhead is very relaxed, but it goes without saying that visitors need to be respectful guests there.

.

Sunday July 22 : Return to Oshkosh:

We will be heading back to Oshkosh on Sunday. There are always things to do the day before the show, but I don’t mind speaking with a builder if that is the only day he has. Keep in mind, this is the set up day for almost all exhibitors, and technically the show is not open yet. Be patient with exhibitors, many of them have traveled a long way, and are under significant pressure to have a successful event, one which can be 30% of a years sales, in a single week.

.

Monday July 23 First day of Oshkosh:

First regular day of the show. My first forum:

First Forum 11;30 am Workshop Classroom C 

at nearly all other times I will be in my booth #616

.

Tuesday July 24th:

Regular day at the show where I will open my booth a little after 8am and be there late into the evening.

.

Wednesday July 25:

Regular day at the show where I will open my booth a little after 8am, head to my Forum, and return to the booth .

Second Forum : 8:30 am Homebuilders Hangar (aircraft spruce hangar) 

In the evening the Panther and Corvair people all gather for a cookout right next to us.

SPA cook out at booth #615 6:00 pm :

Keep in mind this requires a reservation and a ticket, Stop by their booth early in the week and get signed up. It is a big event drawing about 100 people, a very nice dinner before the night airshow.

.

Thursday July 26:

Regular day at the show where I will open my booth a little after 8am and be there until departing for the Zenith dinner at 6:00 pm

Zenith Banquet 7:00 pm at the elks club. Stop by their booth for details. I never miss this evening event.

.

Friday July 27:

Regular day at the show where I will open my booth a little after 8am and be there late into the evening.

.

Saturday July 28:

Busiest day of the show.  I will open my booth a little after 8am and be there late into the evening.

.

Sunday July 29th,

last day of Oshkosh 2018. I will get started a little after 8:00am, but it is an abbreviated day, it is slow, and we begin packing up around 2:00pm. When the show ends at 5:00, I greatly appreciate any help available taking down the tent and packing up the trailer.

.

Questions: 

Q: Will I have manuals for sale? 

Yes, I never leave home without them.

.

Q: If I bring my core motor and parts, will you look at them?

Yes, I always conduct parking lot tours.

.

Q: If my parts are good, will you take them back to FL for rebuilding and conversion?

Yes, My trailer has a useful load of 4,900 pounds, and the truck can carry 3,200 more. If two people with 50% Spruce Goose projects both want me to bring their core engines back, I can still do this.

.

Q: In your booth is it a good for anyone idea to: talk politics, praise the Chinese Government, tell people they don’t like Teddy Roosevelt but worship Steve Jobs, say they really love driving their Prius to Starbucks for a “Venti half calf Mochachino”, blab on their cell through our National Anthem, say things like “who cares about American workers, I keep my Mercedes in my gated community” ,  make any comment implying the Apollo program was fake or that 9/11 was done by bankers from Zurich, or neither Ferdinand Porsche or Verner Von Braun were ‘real’ Nazis, or that Devotion to the ideals of America is an antiquated concept.

No, none of these are a good idea to try in my booth. They have actually all been tried before, with predictable results. I’m actually a pretty thick skinned guy, and don’t expect most people to see things the way I do. Again, keeping in mind the mission is to speak with builders about Corvair engines, I want the limited time we have to be focused on engines. We have always kept this basic idea at the Corvair Colleges, and it has served us pretty well.

I have a personal perspective on America, taught to me by my father’s personal example, covered in this essay: Patriotism has no Party .

Above, Oshkosh 2015. My booth always has this 4’x10′ sign prominently on display, it is easy to see from a long way off. The booth is packed at peak times of the week, but there are also many hours for one on one conversation. In the photo I am standing on the display conducting a Q&A on Corvairs for a large group of builders. If you look closely at the photo you can see ScoobE in the arms of 3,000cc Corvair/Kitfox builder Mike Marury. Because the dog is looking right at the camera, you can tell Grace took this photo.

Builders,

This is the general information page for Corvair College #43. It is being posted on 6/12/18. The on line sign up link is attached below. 

.

Background:

Corvair College #43 will be held at Barnwell SC, 10-12 November 2018:  This is our flagship College.

For a look at the 2015 Barnwell College, check this out: Corvair College #35 Barnwell builders video.

Late tech questions. This is about 1 am on Sunday, nearing the end of a 19 hour day. If you want to pack a lot into a College, good, that is how we do it. However, the free form of the lesson plans allow each person to take in and digest at their own rate and pace. Read a 2013 story here: Who is William Wynne?

.

Is there an on line sign up for this College?

Yes, this is it: https://eventregistration2017.wufoo.com/forms/cc43/

.

Is there a fee for this College? 

Yes, Signing up on line for College #43 is required, and the fee is $99. 100% of this money goes to the local hosts and the Barnwell airport, they provide food an drinks while we are there for three days. The technical support we offer at the College is provided without cost to builders.

.

 Will there be a chance to build an ‘Engine in a Box’ at this College?

We are looking for two builders who would like to buy, assemble and test run a 3.3L “engine in a box kit” For an overview of the 3.3 engine read this story: Build a 3.3L Corvair at the May 18-20 Workshop/Open house. If you are interested in one of these motors, Contact SPA/Panther at 904-626-7777.

.

OK, my project needs progress, what do I do? 

First, sign up for the on line registration. Second, SPA by calling 904-626-7777, or call my number 904-806-8143. We will be glad to speak with you about making sure you are prepared for the event. Making plans early is the key to making progress at the event. At the last hour of a College, prepared builders often say some version of ‘I can’t believe how much I learned and accomplished.’ No one has ever followed that statement by saying ‘I regret being smarter and advancing my goals.’

.

Keep in mind:

 We will also be glad to transport for parts like cases cranks and heads back to Florida.  Even if you are just planning on having these worked on a few months later, sending them back with us gets them in the system and gets the ball rolling.

.

Will you be test running the motors?

Yes. We will have my test stand with us, and perhaps run as many as 10 of the engines being worked on.  The goal is positive exposure and progress, but above all else, learning.

.

Will there be flying Corvair Powered planes there?

Yes, we have had 6-10 every year for the last 10 years.

.

Is there on site Camping? are their Motels? 

Yes, the Barnwell airport has good camping, but no hook us. The town is a mile from the airport, and it has a number of hotels and motels. Do not wait too long to plan, they fill up.

Info Page,Corvair College #42, at Zenith Aircraft.

Builders,

This is the general information page for Corvair College #42. It was originally posted on 6/5/18. The on line sign up link will is attached below.

.

Background:

Corvair College #42 is the “Zenith Invitational” college.   This event will be held in September 21 and 22  in Mexico MO, during the 26th annual Zenith open house. We have previously held 4 colleges at the Zenith Factory, it is an excellent setting and they are very gracious hosts.  The Technical expertise at the College will be provided by myself and Dan Weseman from SPA/Panther.

 Here is what is different: Everyone is welcome to observe, but due to space limitations, the actual wrenching on engines will be limited to 12 builders who we want to ‘approve’ long before the event, and work with in advance to insure their project is educational for observers. That is the ‘invitational’ part. We are selecting the builders based on the degree of prep work they are willing to do, and we are looking for a cross section of engines to represent the wide range of options in building a Corvair.

.

The Zenith open house is open to all experimental builders, not just people currently working on a Zenith ( The Heintz’s are here for the long run, they figure you will eventually be a Zenith builder. ) It draws several hundred serious builders every year, and it also is a major gathering point for component suppliers and industry people. Both of the last 2 EAA presidents have been guest speakers at the event. It is a very pro-homebuilding event in an excellent setting. Surprising things happen there like this: EAA Major Achievement Award.

.

Previous Corvair Colleges at Zenith were held just before the Open House, but in the case we are going to ‘imbed’ College #42 in the Open House so the maximum number of aircraft builders can get a good look at building Corvairs.

.

Would you like a visual on how long we have been working with Zenith Aircraft and holding events at their location? This is a picture from a 2005 Corvair event at the factory…..notice neither Sebastien nor myself had any gray hair then. We have a long history of productive and cooperative relations with Zenith. Read: 14 Years of Corvair Powered Zeniths.

.

How do I find out more information about the Open House? 

You can look at their webpage http://www.zenithair.net and read all about it, including dates, location, maps, accommodations and the schedule for the event.

.

Is there an on line sign up for this College?

Yes, this is it: https://eventregistration2017.wufoo.com/forms/cc42/

.

Is there a fee for this College? 

No, Signing up on line for College #42 is free,  but there will a modest logistics fee for the 12 selected builders who’s projects will be worked on at the College. This Fee will be done directly through SPA/Panther.

.

If there is no fee, and everyone is welcome at the open house, what is the sign up about? 

We would like everyone thinking of attending to use it. First, to be considered as one of the 12  demonstration engines, you have to sign up.  Second, for observers, we are going to send out a number of briefs before the college, including descriptions of the 12 motors and their builders. We will also send out study material so that you can get the most out of elements like setting the valves, installing the distributor and conducting a test run. If we know you are coming and a bit about your project, we can tailor your experience there. Signing up gives access to this information so you arrive at the College informed.

.

If I sign up on line, do I have to show up?

There is no commitment, we are not limited in the number of observers we can have. Even if you don’t have plans to attend at this point, I still suggest signing up, it is a good way to gather information on the content of colleges and the material covered. The information will serve you at future colleges also.

.

What are you looking for in the 12 engines?

We are looking for: 2 Engines in the core stage where they will be torn down and inspected; 2 engines where the builders are ready to close the case; 2 engines with the case closed, and ready for cylinders, one 2,700 motor, one 3,000cc motor; 2 engines ready for heads and valve train; 2 engines ready for starters and distributors, 2 engines ready for the stand.  We are also looking for a builder who would like to buy, assemble and test run a 3.3L “engine in a box kit” For an overview of the 3.3 engine read this story: Build a 3.3L Corvair at the May 18-20 Workshop/Open house.

.

OK, my project sounds like one of those 12, what do I do? 

First, sign up for the on line registration. Second, Contact Rachel Weseman at SPA by calling 904-626-7777. We will be glad to speak with you about making sure you are prepared for the event. Again, only the 12 builders with engines being worked on will have a modest event fee. This assists us in defraying the logistics cost of traveling 1,075 miles, bringing all the equipment and renting the very large commercial tent we will use.

.

I wanted to know if you guys an get a look at my core engine while you are out in the midwest?

Yes, we will be glad to, and this is part of the reason to sign up on line, because we will have specific instructions about this. (We generally refer to these as ‘parking lot tours’ )  We will also be glad to transport for parts like cases cranks and heads back to Florida.  Even if you are just planning on having these worked on a few months later, sending them back with us gets them in the system and gets the ball rolling.

.

Will you be test running the motors?

Yes. We will have my test stand with us, and perhaps run as many as 6 of the engines being worked on.  The goal is positive exposure and progress, and letting people who are yet to select an engine get a good look at all phases of Corvairs.

.

Will there be flying Corvair Powered planes there?

Yes, we have ad 3-5 every year for the last 10 years.

.

Is there on site Camping? are their Motels? 

Yes, the Mexico MO airport has good camping, but no hook us. The town is a few miles from the airport, and it has a number of hotels and motels. Do not wait too long to plan, they fill up with several hundred people coming to town.

.

Do you have links to previous colleges there?

Upcoming Events: Brodhead, Oshkosh, Corvair Colleges #42 and #43.

Builders,

Here is a quick overview of the next four events on deck.  We are just over six weeks from Oshkosh and Brodhed, and we will have continuous updates about there events, but the next detailed notices will be about the individual Corvair Colleges.

.

In the next 48 hours each of the colleges will have its own introduction page, describing what will go on at the event, and how different builders will be served by it. Following these introductions, I will have an update with the on line links to sign up for them. These links will be up by Wednesday or Thursday this week. This may sound a little protracted, but there is a reason, I want to have everyone ready both descriptive pages before signing up for a College, these two events will both be Colleges, but they will have different approaches.

…………………

 

Corvairs at Oshkosh 2018, Every year for the last decade, my booth at Oshkosh has been #616 in the north aircraft display area, right across from Zenith. 2018 will be at the same spot (You rent them a year in advance). We always have a row of parking for Corvair powered planes right behind the tent. Our place and the SPA/Panther booth right next door are an Oasis of traditional homebuilding camaraderie and a gathering point for builders both during the show and after hours. We will also be holding a drawing for a core engine just like last year; Oshkosh 2017 core engine winner.

.

Brodhead 2018: This is the Pietenpol gathering in southern WI, the weekend before Oshkosh. I have only missed a few of them in the last 20 years, but I will be there for 2018. Kevin Purtee and Shad Bell are planning on flying in with their Corvair powered Piets, and many other ‘Piet-vair’ builders will be on hand. It is a great grass roots event.

Corvair College #42 The Zenith ‘Invitational” college.  This event will be held in September in Mexico MO, during the 26th annual Zenith open house. We have previously held 4 colleges at Zenith.  Here is what is different: Everyone is welcome to observe, but due to space limitations, the actual wrenching on engines will be limited to 12 builders who we want to ‘approve’ long before the event, and work with in advance to insure their project is educational for observers. We are selecting the builders based on the degree of prep work they are willing to do, and we are looking for a cross section of engines to represent the wide range of options in building a Corvair. More detailed info on this shortly.

.

Corvair College #43, Barnwell SC will be the tenth College there. Barnwell is our flagship College, always held on Nov. 11th weekend, which this year will be the 100th anniversary of the end of WWI. This will be a large, Full service College with space for 90 builders. We will open the registration up following the detailed description of the event. Over the years, well over 100 Corvair builders have heard their engine come to life at the Barnwell Colleges. If you are determined to join them, follow the detailed story and then the sign up page.

Speculation vs Experience Pt #2, Actual issue identified.

Builders,

The previous story, Internet speculation vs First hand experience….. . , covered how people on the internet were quick to post the most ominous predictions about Alan Laudani’s 3,000cc Corvair, which none of them had seen, nor bothered to understand had been given a full break-in run on my test stand at Corvair College #38, and had previously run perfectly. I dislike our national obsession with offering dire, ominous diagnosis’s on things people have no first hand knowledge of. In Corvairs, I find this annoying because it is commonly done on the internet in a forum where the posters know I have been blocked from directly responding. It is their version of a “Safe Space” where the person with the first hand experience can’t show up and interrupt their cyber-reality commentary.

.

Here is how the ‘problem’ is actually solved: Two people, Alan and myself, decided that resolving the issue was more important than being offended or pushing a pet internet theory. From the first story, it is obvious that I was ticked off, and I used language than anyone with a sensitive ego could use as a justification for permanently putting on an attitude of being ‘offended’ (which of course today leads to a ‘demand for an apology and a call for them to be fired ) I had met and worked with Alan at Corvair College #23 here in Florida, and at #38 in California, and he isn’t that kind of person. He picked up the phone because priority one to him was finding out what was causing the substandard operation on his installed engine, when it had run fine on my test stand. Likewise, I knew that none of the comments offered on the net were correct, so I had an interest in resolving this directly. Although I have a sharp tongue at times, I actually have pretty thick skin and get over things that tick me off at a moment. If I have a redeeming feature it is being aware that a person with my social failings looks stupid being critical of anyone driven by good intentions.

Above, in my hand I hold my own MA3-SPA carb. In my previous story I referenced this warning Safety Alert: Excessively Rich MA3-SPA Jetting. I had to issue this alert because two people quietly acting on their own and without my knowledge, convinced the primary supplier of rebuilt carbs to Corvair builders, to rebuild them to run ridiculously rich. All anyone with a Corvair needs to know about these carbs is that Dan Weseman and Myself, long ago proved in several hundred test runs, on professional professional dyno runs and in our own aircraft over the last 15 years, every Corvair from 2,700 – 3,300cc should be run with completely stock jetting, the same as an O-200.

.

Several years ago, the rebuilder sent out more than 30 carbs where were radically rich. We have the serial numbers in the Safety Alert, but not all of the carbs have yet been returned for correction. Guess what, when Alan and I spent an hour on the phone, we discovered by checking the list of affected carbs, he has one of them on his plane.  Smoking gun identified. My test stand has a completely stock MA3-SPA on it, and with it Alan’s engine ran perfectly. On his plane he installed the super rich carb and it ran poorly and actually fouled the plugs. In checking the installation he found his timing slightly retarded, but that is a non-issue compared to the carb being 30% too rich.

.

To originally discover the altered carbs in the field, it took Dan Weseman and I several months of speaking with builders on the phone to piece together that something was foul. When this was tracked down, the two individuals responsible, who remain unapologetic, should have become Persona non Grata in Corvairs, for the grief and damage to the reputation of Corvairs they caused. But in cyberville what they did was A-OK, and they are both regulars on the Corvaircraft discussion group, the location where Alan received the incorrect speculation on his issue. However having first hand experience with several hundred Corvairs is a crime in cyberville, and for it I am banned from writing to, or reading the archives of the same discussion group. Consider that when contemplating sources of information.  And the final irony? One of the people on the net who offered speculation to Alan is one of the two culprits on the carb issue.

.

.

Would you like to learn more about MA3-SPA carbs? Read this linked story, the quote below is an excerpt from it: MA3-spa carb pictures, Wagabond notes.

.

“It is a free world, and  you can use any carb you like on your Corvair.  Physics, Chemistry and Gravity also think it is a free world, and they fully support your right to make a poor choice, even one that will harm you if it doesn’t work within their system of laws.  If you wanted to run a German motorcycle carb, don’t be mad at me if it doesn’t work. I didn’t make up the laws of the physical world. I am just the messenger here to remind people that Physics, Chemistry and Gravity are great allies if you play by their rules. They are also absolutely remorseless in dealing with people who feel like the rules don’t apply to them. Be advised, if they find you guilty, the penalty phase of the system moves much faster than our criminal courts, and does not have an appeals system.”

Internet speculation vs First hand experience…..

Builders:

In the last few days, A guy on the West Coast named Alan Laudani, who has questions about his running Corvair engine, went on the Corvaircraft Internet Discussion Group and wrote a story about his engine failing to turn enough RPM with a ground adjustable prop set at a very high pitch setting. He received a lot of speculative “advice” from people who have never seen the engine in question, and in all likelihood have never met Alan.

.

They offered the following “Ideas”

.

Ed Lee said the cam timing might be wrong and said he was certain it should turn more rpm because his much smaller wood prop does……..

.

Mark Langford gave an example of a person with the wrong cam in his engine, referenced a computer predicted result, and suggested the engine be tested with a known prop previously run on the same size Corvair. He went on to suggest running the engine without a prop to check the timing, because it was ‘less risk to life and limb’…….

.

Roy Szarafinski said several things, but suggested checking the compression, he went on to suggest the mixture could be very wrong on the motor……….

.

Earnest Christley chimed in to suggest a compression check, asked if there was a lot of blow by, and went on to speculate that it had the wrong head torque, and Alan should seriously look at the possibility that the engine has broken piston rings………..

.

Somewhere in there Dan Weseman, pointed out that the engine had been run already at a Corvair College, ……but this comment was ignored by the speculators who had never seen the engine, but were sure they knew it had something wrong. Notice how quickly they escalate to ‘broken piston rings’.

.


.

Above, a picture I took myself, May 9th 2016 in Cloverdale California, where the engine in question had just been run on my test stand.  Unlike the people on the discussion group, I had seen the engine run in person, and had worked directly with Alan.  I even documented it on my website. The picture is Alan standing beside his engine just before the run. Read the story: Alan Laudani 3,000 cc runs at CC #38, and in case you think it is a hoax, read the Comments also, where Alan includes his email address and thanks several people, including myself and Jerry Price for working on the engine. I’m kind of wondering why Alan went to the internet to find strangers to comment on his engine instead of contacting myself or Dan, and I’m really wondering why he failed to mention to anyone on the net that I had driven all the way from Florida on a 7,200 mile circumnavigation of the US, and Alan’s engine, and all the others on the trip, were run at for free at the events. Evidently he values the speculation on the net over direct in person assistance.

….

In case you are wondering:

.

I ran the engine myself and it was in fine working order.

.

The cam timing was not wrong, I can spot this in an instant by watching the motion of the #1 intake rocker and looking at the timing mark on the balancer.

.

The warp drive prop on Alan’s plane can not be compared to the wood props mentioned. The diameter of the Warp prop will not allow it to turn the rpm of a 54″ wood prop.

The engine was run with the prop pictured, my test prop, which has run more than 300 Corvair engines in the last 14 years. ( It has been repainted, but it just ran 4 more engines last weekend) I always have an optical tach, my $79 Equis timing light has a built in digital tach, and after 300 engines on the same prop, I can usually call the rpm of a Corvair plus or minus 35 rpm by sound and throttle position alone. ( If you want to lose $100, bet me I can’t do this at the next Corvair College). I have said this countless times, no Corvair should be run without a prop. There is no cooling, but more critically, the prop is the ‘governor’ which prevents the motor from hitting 7,000 rpm in the blink of an eye.

.

I can also tell the compression of a Corvair by turning the prop over by hand. In setting an engine up on my stand, I always do this, and after hundreds of them, it is easy to tell by turning the prop if each individual cylinder has compression. Also the suggestion the motor might be running with the wrong mixture comes from the very person, who along with Ron Lendon, caused this mess: Safety Alert: Excessively Rich MA3-SPA Jetting..

.

All engines run on my stand are observed for blow by out the vent tube, 15 years ago I did extensive volume measurements by timing the flow to inflate a 30 gallon trash bag. I an say that Alan’s motor had completely normal blow by for an engine breaking in.  There is no way, short of heads so loose it didn’t squeeze the gaskets, that low rpm could be caused by head torque. Know this: an engine with a blown head gasket will make more than 90% of the rated static rpm. Leak down has very little effect on static rpm. ……and let me add that it 29 years of doing this, I have had an occasional builder break a ring putting the piston in a bore, but never, not once, have I ever had a builder break any piston ring on the test run, not once in hundreds of runs.

……

OK, so what is wrong with Alan’s motor? 

.

Simple, he is using a junk tach, that he says in his post will not even read above 2,000 rpm, additionally he mentions trying to run it directly of his MGL “glass cockpit” although I have very specifically warned people to NEVER do this: MGL vs Corvair ignition issue. In short, Alan has no idea what rpm his engine is turning. He could just use a cheap timing light to get real numbers, but he would rather short out his ignition by wiring it to a South African “Glass Cockpit” maybe time to pay attention to basics and buy a timing light. Spending thousands of dollars on an imported screen that has a notorious ability to hurt ignitions, and then trying to run a junk Westach tachometer is an example of poor decision making.

.

On the internet Alan now states with the tips at 6 degrees, ( a setting way too low to fly ), it only turns 2,710 rpm. A Standard 2,700cc Corvair can turn the same prop that rpm with 2.5 more degrees of pitch. The only reasons why Alan’s 3,000cc Corvair would yield that number are 1) the tach is wrong 2) He isn’t measuring the pitch correctly, 3) If he actually did try to extensively run the engine with 15 degrees of pitch, and held it at wide open throttle with the rpm below 2,200, he very well could have damaged the engine by detonating it. There is a reason why I tell people the 2,700rpm should be the minimum static rpm used. read:Critical Understanding #2, Absolute Minimum Static RPM., which includes the quote “The primary group violating this Critical Understanding of Corvairs are builders who have made their own props and builders using a ground adjustable props with too much pitch in the setting.

.

Alan started out with a ridiculously high pitch setting, and now is trying a ridiculously low one. I would have told him this if he bothered to call.

.

Hey William, if you have all the answers, why don’t you go on Corvaircraft and set Alan straight? 

.

Simple, I have been banned from posting anything on Corvaircraft for the last seven years, because clearly, people who offer random speculations on a motor they have never seen are offering much better education and service than myself, who drove all the way across the US and ran the guys engine for free. I must be the major impediment to anyone getting their engine running. Yes, Al Gore invented the internet and gave everyone an equal size soap box to speak from, and that made the world a better place, where the average of the speculation is always a better answer than just asking the guy who ran this specific engine and a few hundred others like it.

.

If anyone just started looking at Corvairs on the net, and read the exchange about Alan’s motor, what conclusion would they come to? Does it accurately portray my service to builders or my understand of the engine or my willingness to share this with builders? I think not.

.

I’m actually looking forward to hearing if Alan ever goes back on Corvaircraft and tells people why he failed to mention his engine running on my stand and why he let others speculate on an engine he had already see run correctly. For builders with actual plans of being honest and learning something, you can always call my cell phone 904-806-8143.
