    Subject: Re: CorvAircraft> Dual Ignition toggle
    --> Zenith-List message posted by: "Scott Laughlin" <cookwithgas@hotmail.com> Guys and Gals: Here's William's explanation of his dual ignition setup in the 601XL - I asked him for help on the subject and he asked me to forward the reply for the group's benefit. I noticed there are a lot of 601XL builders using the Corvair, so I'm copying the Zenith-list with this post: Enjoy, Scott Laughlin A lot of people get focused on hardware in the ignition system and loose sight of the Two main points: It must work as a complete system and you must recognize that the pilot is the weakest link in the plane. Here is what we fly, and why we set it up this way: On the 601XL's Installation: One DPDT switch high on the panel, centered in front of the pilot. Side 'A' has one ignition on it and the primary fuel pump on it. this pump is wired through the oil pressure cut off switch. Side 'B' has the same thing but the fuel pump is not run through an oil pressure switch. Starter is a button on the panel hit with the index finger of the throttle hand without lifting it off the throttle. Key switch controls only the master. Operation: Engine is started on the 'B' side because the pump will run without the engine running. Both systems checked on run up. Take off and landing always done on 'A,' because in the event of an accident, the fuel pump will stop automatically. Logic: Mark Langford inspired this design. The starter location is a Bob Lester tip. Pilot takes off and the power drops for any reason, Just move the switch to the other position. This eliminated the pilot having to diagnose anything. With an alert pilot, the time is much faster than 1 second, and it always will beat any set up where the pilot has to look at a gauge to know what switch to hit. Even if the pilot is at 100 feet, and he waits 4 seconds, and restarts, he will loose only 50 feet or so. If you are frequently clearing anything at your airport by less than 50 feet, or it takes you more that for seconds to flip a switch and hit a button, you need a whole new game plan.... This system is simple, proven, takes into account the pilot and the 601's need for fuel pumps. Do Not: wire the coils to 2 on off switches. Without fail, at some point you will have them both in the off position. Do Not: use Pertronics ignition parts in place of the points. They are voltage sensitive, and quit working when the voltage drops. Points fly on long after these stop working. If you are worried about switching ignitions after one side quits suddenly, you want points because the almost always fade out slowly. When the pertronics part is starved for voltage it quits suddenly. and you cannot have a points back up because the pertronics part covers the points cam. Do Not: Adjust the points in a WW distributor to the same gap. I set them in the machine to have the exact same timing. This sometimes causes the to have slightly different, but in spec., point gaps. If you spot this and "fix" it, you will have a bigger variation on rpm when switching from 'A' to 'B." William

    Subject: Re: CorvAircraft> Dual Ignition toggle
    --> Zenith-List message posted by: Paul Mulwitz <p.mulwitz@worldnet.att.net> This whole diatribe leaves me with two big questions: 1. What is wrong with having both ignitions operating at once as is commonly done on certified aircraft engines? This allows the pilot to spend his attention on flying the plane instead of managing the engine in the (apparently common for William's resurrected Corvair engines) event of an ignition failure. 2. I find it ironic that a salesman who says the weakest part of his customer's system is the customer gets such a zealous following.

    --> Zenith-List message posted by: "Hinde, Frank George (Corvallis)" <frank.hinde@hp.com> Great...Right up until the switch fails! All of this comes down to personal preference. On my Stratus I have the primary ignition on the key switch and the second ignition, pump1 and pump 2 all on separate on-off switches. The left and right systems are wired from each independent battery. For take off I run both fuel pumps and both electronic ignitions all the time. I have a LOUD audible warning buzzer if I inadvertanty switch off both pumps I always have both pumps running for TO and landing. None of this is wired through an oil pressure relay, not that I think this is a bad idea necessarily, in fact it does give you a BIG warning your engine is about to (or just has) seize. I personally couldn't imagine the stress in waiting for the second pump to partially fill the float bowls, particularly if you are having to wait for the second pump to prime and suck form the tank some feet away (hence my pumps are in the wing roots) ....But that's just me Note I have run both ignitions continuously for 400 hours without ill effect...I don't know what the Corvair setup is though.. Frank On the 601XL's Installation: One DPDT switch high on the panel, centered in front of the pilot. Side 'A' has one ignition on it and the primary fuel pump on it. this pump is wired through the oil pressure cut off switch. Side 'B' has the same thing but the fuel pump is not run through an oil pressure switch.

    --> Zenith-List message posted by: "Gary Boothe" <gboothe@calply.com> Heck, there are guys out there actively looking for Model A engines to put on their Pietenpols! But I still would not call that "resurrecting" an engine. All we're trying to do is build an airplane, for a variety of reasons; cost, nostalgia, design appeal, etc. As for WW calling the "customer" a weak link - I guess I would have to agree. The design is tried and tested. The engines and props are tested. The theory of flight is tested. The only thing untested is each individual's ability to build something. My guess is that William makes those kinds of comments to remind us that we need to check and double-check, even triple-check, everything we do. We need to recognize the fact that we are the wink link. Scott, your contributions are numerous and positive. Thank you! Gary Boothe Cool, CA 601 HDSTD, WW Conversion Tail done, working on wings....

    Subject: Re: CorvAircraft> Dual Ignition toggle
    --> Zenith-List message posted by: "Craig Payne" <craig@craigandjean.com> Ignoring the prejudicial tone of your message I'll toss-out some answers. If you are actually interested in more answers to your first question just search the Corvair list archives. 1a. MSD (the maker of the coil mixer used in the design) recommends against using both sides at the same time. There is another coil mixer (from Mallory??) which is spec'ed for dual operation. 1b. Unlike a dual-plug engine with wide pistons in the dual-coil, single-plug design there is no appreciable RPM drop when one side is lost. So if you are cruising on "both" and any of the redundant parts fail you will have no indication. 1c. "apparently common...ignition failure" - this has no basis in fact. Every aircraft is design to handle failure modes. 2. The majority of accident investigations end in a conclusion of "pilot error". -- Craig

    Subject: Re: RE: Re: Corvair Dual Ignition toggle Information
    --> Zenith-List message posted by: "Doug Eatman" <pilotdna@hotmail.com> Scott, Thank you for sharing this information. I am not going to get into the systems layout debate, or scrutinize the possibility of a switch failing, but I am going to caution listers against one major sin: insulting individuals, by name, that they have never met or spoken to in person. William Wynne is not a salesman. He has contributed far, far more to my motivation and progress in building an airplane than I have come close to compensating him for financially. He has given me hours of one-on-one advising in his own hangar, welded a few small parts for me for free that the university machine shop wouldn't touch due to liability, given me engine parts for free to replace what my core engine was missing, allowed me to use his tools for my own project when I lacked what was needed, took me flying in his airplane, and even laughed it off when I damaged his wrist pin fixture by not paying attention and crushing it too far in his hydraulic press. My total payment to him: $59 for his conversion manual. He is an honest, well meaning, experienced mechanic. He is not a salesman. If you have other proven methods of making airworthy systems, go ahead and explain your ideas. Question other peoples' ideas if you like. That is the purpose of the list, and that is how new ideas are shared. We all appreciate input. Do not attack the credibility of individuals, especially those that you do not know. That is rude and it is not the purpose of the list. I do not want any personal emails on this matter. I am in the middle of final exams for my aerospace/mechanical engineering degree program and have spent too much time on this list already. -Douglas Eatman do not archive

    Subject: Re: RE: Re: Corvair Dual Ignition toggle Information
    --> Zenith-List message posted by: Paul Mulwitz <p.mulwitz@worldnet.att.net> Let me start by expressing my continuing amazement at the logic of some of the posters to this list. In this one, a lister directs heavy personal criticism against me in the name of not using the list to criticize individuals. I guess his real message is it is ok to criticize anyone but the great William. I am also amazed at the people who pointed out this list is an inappropriate place for my comments and questions about engine reliability while happily accepting the incredibly long post that was announced as a duplicate of information posted on the Corvair list. In the future I hope that any William Worshipers who want to tell others that there is new information on the Corvair list will do so with a link rather than a long winded copy of the information. To those who I offended I offer my apology. To those who think this list is not an appropriate place to question the value of Corvair engines, I suggest you grow a thicker skin. My special thanks to Craig for actually answering my question about the manual ignition change/over switch. He pointed out that the Corvair (like other auto conversion engines) only has one spark plug per cylinder. That was new information to me and, I believe, very important information. It points out that these engines don't really have dual isolated ignition systems. Indeed, a single spark plug fouling will put a cylinder out of commission until it is cleaned.

    Subject: Landing/Taxi Lights & wee bits
    From: "Wentz, Don" <don.wentz@intel.com>
    --> Zenith-List message posted by: "Wentz, Don" <don.wentz@intel.com> As the manufacturer of the LL kits for Van's Aircraft, I thought I would throw in a few comments and reasons that I have found. 1 - Placing the leading-edge lights further outboard - Eliminates glare from the light hitting the prop disc, surprisingly visible on a dark night - Helps illuminate the edges of the run/taxi ways - Does not 'violate' the "D-Section" of the wing leading edge at an inboard location, where stresses are higher and 'could' be a structural issue 2 - I usually recommend a single light be mounted in the left or pilot's wing on side by side RVs, especially the taildraggers, as visibility over the nose on the ground can be limited on the right side. Not likely an issue on the Zenith as the cowl is lower/narrower, most are tricycle gear, so in the right wing makes some sense, except for the possible benefit of the pilot being able to see the closest edge of a dark taxiway on his left. 3 - We keep the opening in the top of the wing as small as possible - you don't need or want light spreading up as it can be a distraction/visibility issue in mist/haze/rain, especially if you try to scan the horizon. 4 - Moving inboard 1 bay is not likely to cause an issue. 5 - Switching a 2 light setup with 2 switches is a good idea, more flexibility. 6 - I ground everything to the airframe in my RV-6, 12 years and 925hrs with no issues. 7 - Consider buying a $15 flasher from Galls Inc, flashing lights are more visible.

I think the light location was chosen to allow for the long range tank installation. I have the two tanks per wing which prevents moving them inward. So, I'm betting that if you have the single inboard tanks, moving them inward is the most practical thing to do. It would move the weight a wee bit closer to CG, eliminate a we bit of wire, and probably make the lights a wee bit more effective, and perhaps some wee bits I'm overlooking.

    Subject: Flying Report: 601XL/Corvair
    --> Zenith-List message posted by: "Phil Maxson" <pmaxpmax@hotmail.com> This weekend, Gus Warren, flew my 601XL/Corvair from Edgewater, FL to my home airport in Hackettstown, NJ. As many of you know, I completed my engine in William's Hangar, and then took my plane back to them to finish the cowling, paint and electrical system. Well, this weekend was the culmination of my dream to build and fly my own airplane. Gus and I flew around for a few days and he showed me how things work. And DOES IT EVER WORK! Even with my limited experience in the plane I was making the shortest take offs at my home field of all the planes out there. My plane was able to make it to pattern altitude faster than I could have expected. I don't have a vertical speed indicator so I can't give details, but it climbs beautifully. This was worth waiting 6 years for! Best of all, when anyone sees it for the first time, they ask what kind of plane it is and they are impressed, but when the find out it is Corvair powered, they are really interested. I can't thank William Wynne and his gang at flycorvair.com enough. They finished my plane, made it look beautiful, and then DELIVERED IT to me and helped me become familiar with it. You don't find nice people like them every day. There is a video of my plane on the flycorvair.com web site: http://flycorvair.com/601mxvid.wmv Phil Maxson N601MX 601XL/Corvair

    --> Zenith-List message posted by: "cgalley" <cgalley@qcbc.org> 2700 is NOT a high rpm. Think of all the cars that run 5000 to 8000 rpm with only one plug. The speed of the flame front is very fast, especially at 2700 rpm. Plug redundancy may help flame front speed but tell that to a Ferrari that is turning 12 grand on one plug per cylinder.

    Subject: Re: RE: Re: CorvAircraft> Dual Ignition toggle
    --> Zenith-List message posted by: Brandon Tucker <btucke73@yahoo.com> Paul, You are correct that if one spark plug fouls, neither ignition would fire the plug, and the plug must be cleaned. To my knowledge, it has never happened, but it is a possibility. This is where the extra 2 cylinders would be a good thing. The piston area of the lycos is so large that running both spark plugs will produce a much more complete fuel burn, as proven by the RPM drop on mag checks. The same results would likely not be realized in the corvair with such a small diameter piston, even with two spark plugs, so running both ignitions does not help there. Only in the case of seamless failure is it beneficial to run both. If there were not an efficiency benefit of running both ignitions in aviation engines, would we still always run both? The answer is yes, because it is convention and how everyone was taught, but would it be convention? I learned in a turbo prop and am fairly new to piston engine aircraft with only 300 hours in pistons, so I feel unbiased here. There are arguments that if you run both ignitions all the time, you would have no indication of a single ignition failure. Sure, you do a mag check on the ground, but what happens if it fails at takeoff? You continue on the other ignition unaware that one failed, just for the second to fail after climb out. If you run one at a time, you simply switch to the other ignition on failure, and if on climb out, can turn downwind, and land immediately. This, in my opinion, is valid argument. Having separate switches for the ignition systems is a good concept as well, but it can be argued that one could accidently shut them both off. Not likely, but possible. With a single switch controlling both ignitions (like my system), switch failure can cause a forced landing. It happened in an RV recently. What is the best way to go? Who the hell knows. If we keep it civil, we will all make more informed decisions. Since the accident in the RV, I have become aware that my automotive key switch could be a weak link in my system, through civil textual conversation on the corvair list. I have a 3 position switch that allows me to run ignition 1, 2 or none. I am considering a separate emergency ignition switch run independently from the rest of my electrical system feeding both ignitions, just in case the key switch or ignition switch breaks. I have a header tank, so all I need in an emergency is an ignition.

Think of all the cars that run 5000 to 8000 rpm with only one plug. The speed of the flame front is very fast, especially at 2700 rpm. Plug redundancy may help flame front speed but tell that to a Ferrari that is turning 12 grand on one plug per cylinder.

    Subject: Official Zenith-List FAQ (Frequently Asked Questions)
    --> Zenith-List message posted by: Matt Dralle <dralle@matronics.com> Dear Listers, Please read over the Zenith-List Frequently Asked Questions (FAQ) below. The complete Zenith-List FAQ including the Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/Zenith-List.FAQ.html Thank you, Matt Dralle Matronics Email List Administrator [ Note: This FAQ was designed to be displayed with a fixed width font such as Courier. Proportional fonts will cause display formatting errors. ] This FAQ can also be viewed in HTML online at the following address: http://www.matronics.com/FAQ/Zenith-List.htm ************************************************************ ******* LIST POLICIES AND FREQUENTLY ASKED QUESTIONS ******* ************************************************************ PLEASE READ. This document contains Zenith-List policies and information for new and old subscribers. Understanding the Zenith-List policies will minimize problems for the Administrator, and will help keep the Zenith-List running smoothly for all of us. **************************************** *** How to Subscribe and Unsubscribe *** **************************************** Simply go to the Web Page shown below and enter your email address and select the List(s) that you wish to subscribe or unsubscribed from. You may also use the handy "Find" function to determine the exact syntax of your email address as it is subscribed to the List. Please see the complete instructions at the top of the Web Page for more information. The Subscribe/Unsubscribe web page is: http://www.matronics.com/subscribe Note that you will receive TWO conformation emails regarding your subsciption process. The first verifies that your subscription/unsubsciption request was received, and the second confirms that the process has been completed. You should receive the first email within a few minutes of your request. The second conformation will arrive in less than 24 hours. You cannot post until you receive the second conformation email message. ***************************** *** How to Post a Message *** ***************************** Send an email message to: zenith-list@matronics.com Your message will be redistributed to everyone currently subscribed to the List. ***************************************************** *** SPAM Fighter - You Must be Subscribed to Post *** ***************************************************** When a new post is received by the system, the From: line of the message is checked and compared against the current subscription list. If the email address is found, the message is passed on to the List Processor. If the email address isn't found in the current list of subscribers, it is dumped. This serves to very effectively thwart 99% of the SPAM that gets posted to the Lists. Remember, however, that the syntax of your email address is very important with regard to the configuration of your email application such as Outlook or Eudora. For example, the following two email addresses may be functionally equivalent, but only one would pass the Matronics Email SPAM test depending on which was syntax was subscribed to the given List: smith@machine.domain.com smith@domain.com Either email address syntax is alright, just be sure that you configure your email application to match *exactly* the address you've subscibed to the List. ***************************************************************** *** Enclosures Stripped Out - Can't Get a Virus From the List *** ***************************************************************** Any enclosures that are posted to the List will automatically be stripped off, and ONLY the plain/text portion of the message will be forwarded to the List. Please configure your Email application to send Plain Text Only, and disable any "Quoted Printable" or "HTML" encoding whenever possible. Because enclosures are stripped out of incoming posts to the List, the likelihood of getting a virus from the List is extremely small. If you do receive a message that appears to be from the List, and it does include a virus, it is very likely that it was sent *directly* to you from someone on the List who has a virus. This is a specific kind of virus, and you should try to inform the sender, if possible. The best protection against viruses is a good virus protection program such as Norton Antivirus. State of the art in virus protection today's world gives maximum protection with little or no negative impact on the computer system. You can't afford to be without a good virus protection program these days. Note that some limited enclosure posting is now enabled on a number of Lists. Allowed types include .jpg, .gif, .txt, .pdf, .xls, and a few other similar types. ******************* *** Digest Mode *** ******************* Each day, starting at 12 midnight PST US, a new 'digest' will be started. This digest will contain the same information that is currently appended to the archive file. It has all of the headers except for the "From:" and "Subject:" lines removed, and includes a message separator consisting of a line of underscores. Each day at 23:55 PST US, the day's messages as described above will be combined and sent as a single message to everyone on the digest email list. To subscribe to the digest list, use the same subscription web form described above, and just select the Digest version of the List. http://www.matronics.com/subscribe Note that you *can* be subscribed to both the realtime and digest versions of the List at the same time. This is perfectly acceptable. Now some caveats: * Messages sent to "zenith-list-digest" will be forwarded to the standard email list. In other words, you cannot post messages only to the digest List. * If you are subscribed to both the regular List and the digest List, you will receive the realtime postings as well as the digest at the end of the day. * If you reply to the digest email, your message will be forwarded to the normal list associated with the digest. Important Note: Please change the subject line to reflect the topic of your response! Also, please *do not include all or most of the digest in your reply*. **************************** *** List Digest Browser *** **************************** An archive of all the List Digests can be found online in either plain text or HTML format. These archives contain the exact Digest that was posted to the Digest email list on the given day. The Digest Archives can be found at the following location: http://www.matronics.com/digest ***************************************** *** The "DO NOT ARCHIVE" Message Flag *** ***************************************** At times, your message may concern something that is revelent only to a very small number of persons or to a limited area, and you may not wish to archive it. In such a case, simply put the following phrase anywhere in the message: do not archive Your message will not be appended to the archive, but will be sent to List email distribution as normal. ********************************************** ***** READ THIS - Automatic Unsubscribes ***** ********************************************** Note that if your email address begins to cause problems such as bounced email, mailbox is filled, or any other errors, your address will be promptly removed from the List. If you discover that you are no longer receiving messages from the Zenith-List, go to the following Web page, and look for your email address and a possible reason for your removal. The Matronics Email List uses utility called the "Email Weasel" that automatically looks though the day's bounced email for addresses that caused problems due to common things like "user is unknown", "mailbox full", etc. If the Email Weasel removes your email address from the Lists you will find record of it at the following URL: http://www.matronics.com/unsubscribed If the problem listed on the web site above has been resolved, please feel free to resubscribe to the Lists of your choice. ******************************* *** List Member Information *** ******************************* If you have not done so already, please email me your phone numbers and paper mail address in the following format: smith@somehost.com Joe Smith 123 Airport Lane Tower, CA 91234-1234 098-765-1234 w 123-456-7890 h Please forward this information to the following email address: requests@matronics.com I have a file of such things, that I typically use to contact you when there are problems with your email address.

You will also need to Subscribe to the respective Email List as described above to receive the Email Distribution of the List, however. The Matroincs Email List Web BBS Forums can be found at the following URL: http://forums.matronics.com ********************************* *** Matronics Email List Wiki *** ********************************* In an attempt to make it easy to store and find structured and often accessed information, Matronics has installed a Wiki at: http://wiki.matronics.com The Wiki allows individuals to create web pages to contain useful information for other users of the mailing lists and web site. Unlike an ordinary web page where the content needs to be submitted to Matronics for inclusion, the Wiki permits the users to construct their own pages and have them visible immediately. While constructing pages for the Wiki is not difficult, some may not be comfortable building pages. In that case, simply prepare the text and any images and email it to: wiki-support@matronics.com One of the volunteers on that list will take your submission and construct a Wiki page for you. Often someone produces a particularly useful posting in email one one of the Lists that would be of general interest. In that case Matronics may take that post and convert it into a Wiki page. ********************* *** List Archives *** ********************* A file containing of all of the previous postings to the Zenith-List is available on line.

I will often offer free gifts with certain contribution levels during the Fund Raiser to increase the participation. The gifts are usually donated by companies that are themselves List members. Your Contributions go directly to supporting the operation of the Lists including the high-speed, business-class Internet connection, server system hardware and software upgrades, and to partially offset the many many hours I spend running, maintaining, upgrading, and developing the variety of services found here. Generally Contributions range from $20 to $100 and are completely voluntary and non-compulsory. I ask only that if person enjoys the Lists and obtains value from them, that they make a Contribution of equal magnitude. Contributions are accepted throughout the year, and if you've just subscribed, feel free to make a Contribution when you've settled in. The website for making SSL Secure Contributions is listed below. There are a variety of payment methods including Visa and MasterCard, PayPal, and sending a personal check.

The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. - Occassional posts by vendors or individuals who are regularyly subscribed to a given List are considered acceptable. Posts by List members promoting their respective products or items for sale should be of a friendly, informal nature, and should not resemble a typical SPAM message. The List isn't about commercialism, but is about sharing information and knowledge. This applies to everyone, including those who provide products to the entire community. Informal presentation and moderation should be the operatives with respect to advertising on the Lists. ------- [This is an automated posting.]
