    Subject: Strobe lights temperature
    Hello, I have tested my Whelen strobe lights on the bench before installing them, and one of them (the tail one) is overheating (95=B0C !! after a couple of minutes), although working fine. But it smells like a hot electric device. I cannot get from Whelen whether it is normal or not... I'd like to have the opinion of other users to compare with... Thanks in advance, Philippe Brussels - Belgium

    Subject: multi detent 10k potentiometer?
    7/1/2007 Hello cj, I recently drove a Chevrolet Malibu rental car that had a click knob rheostat to control the fan speed on the air flow to the car interior. The knob itself was probably too large for your use, but you might check with the parts section of a local dealer to find out what the insides are. 'OC' Says: "The best investment we can make is the effort to gather and understand knowledge." Time: 02:53:23 PM PST US Subject: AeroElectric-List: multi detent 10k potentiometer? From: "Chris Johnston" <CJohnston@popsound.com> Ok smart guys...get ready for a dumb guy question! What do you call a regular old 10k pot that has multiple detents on it? I'm trying to find a single turn 10k pot that has a click feel, maybe 20 detents or so, to use with a PWM dimming system for an lcd inverter. But I have no idea what to call it! so I can't look for it! I tried and tried, but all I find is pots with center detents, or pots with a switch at the end, but that's the only detent. I'm very frustrated, and feeling very stupid. Can someone smarter than me help me out? Btw, I do know what it's called when you cross a hippopotamus, an elephant and a rhino. Hellifiknow! Sorry. and thanks. cj #40410 www.perfectlygoodairplane.net

    Subject: Automatic upper cowl flap
    Since I'm using a Subaru engine, I need to have some kind of ventilation exit on the upper cowling, to dissipate heat after engine shutdown. Most builders just make a row of 3/4" holes, and others put side louvers that look like shark guills. I intend to make the upper row of holes, but don't want to let them always open, due to the possibility of rain penetration and also because they can have a bad influence in the cooling air flow inside the cowling. Therefore I thought of a small (some 15" x 1 1/2") moving flap, which covers the holes, and is normally closed in flight. Now the electrical challenge, that I put here to the smart guys of this list: The ideal solution to manouver this flap would be to automatically open it when the engine is turned off. How can it be done? Carlos RV-9A P.S. - I know this is not a KIS solution...

    Looking at my Comant CI-122 antenna, it looks as though they intend the mounting screws to contact the fuselage electrically. I can find no instructions in this regard on the Comant website (if any one knows of any, please tell me). The gasket thay give you pretty much rules out contact of the antenna's base with the skin of the plane, at least in any reliable way. The screws seem to it. I've mounted platenuts on my doubler plate and I'll see that it has contact with the (bare) fuselage skin underneath, but I'd like to see some more positive connection. Does any one have any Comant documents that addresses mounting details like this? -- Tom S. , RV-6A

    Subject: Re: Automatic upper cowl flap
    Ron, Without knowing what you plan to use to open/close the flap, the electrical seems like putting the cart before the horse. The simplest system might have a device that incorporates a coil to contract/extend a control rod. Arrange it is such a manner that the unpowered position maintains the flap open, the energized position closes the flap. You also need to consider pressures inside/outside the cowling with the design to determine whether the device would operate as expected under the anticipated pressures if not using center pivoting on the flap. I use a Sube and my solution will be the oil fill hatch, at least in the near term.

    Hi Carlos, I'd not recommend you add ventilation for a Subaru engine. The heat from this water-cooled engine never approaches temps seen in an air cooled engine. I read 210 degrees on a very hot day and by the time I've taxied back to the hangar, the temps settle back to 180 degrees F.

However, what I'm looking for in this list is an automatic system to open it, connected to the electrical switch that shuts down the engine. Carlos

    Carlos, It may be that a car needs this for idling around town at stoplights and for lugging up a hill in the summer, but with a good cooling system in the plane, Subaru temps drop off from 180 to ambient rather quickly. The heat from an air cooled engine and its exhaust pipes would be much higher, but I'd get a recorded temperature reading in the upper rear cowl before putting any work into a vent. Realizing Eggenfellner is a purest and has good product, exceeding the requirements is what they do best. Hard to argue that. I'd still put a temp sensor there for run up and get a reading on peak temps after shut down. We'd really be interested in what you find.

If you limit the door's travel to less than 90 degrees, air pressure during flight will push it closed. When you shut down, it will drop open. It's been done by others to achieve what you're after.

    Subject: Re: Automatic upper cowl flap
    Carlos, Not sure why one would be concerned about doing that from the cockpit. If I wanted something to open right away when the engine was shut down, and before I could exit the cockpit, a gravity flap would be my preference - it should close once the cowling is pressurized (but that begs the question of why it would be pressurized - doesn't that mean there is more airflow into the cowling than wants to escape, i.e., drag?). If that didn't work, I would next consider a simple push-pull mechanical lever that would push the flap closed when pushed full forward, back to open. Last option would be an electrical one.

    Subject: Re: Automatic upper cowl flap
    Larry, Would generally agree with you, but in my case, there is a header tank in the engine compartment and getting the heat out helps to keep from heat soaking the fuel which could cause vapor lock problems. Eggenfelner's reasoning may be similar even if there is no such tank. Carlos did not mention that he had one, so assume it would be to limit heating of the fuel in the fuel lines.

    Subject: Official AeroElectric-List FAQ (Frequently Asked Questions)
    Dear Listers, Please read over the AeroElectric-List Frequently Asked Questions (FAQ) below. The complete AeroElectric-List FAQ including the Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/AeroElectric-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/AeroElectric-List.htm ************************************************************ ******* LIST POLICIES AND FREQUENTLY ASKED QUESTIONS ******* ************************************************************ PLEASE READ. This document contains AeroElectric-List policies and information for new and old subscribers. Understanding the AeroElectric-List policies will minimize problems for the Administrator, and will help keep the AeroElectric-List running smoothly for all of us. ****************************************** *** Quick Start Guide to List Features *** ****************************************** There are many features available on the Matronics Email Lists and each one is described in detailed below. However, using the List Navigator you can quickly access the complete set of features available for this List. The List Navigator can be found at the following URL: http://www.matronics.com/Navigator?AeroElectric-List **************************************** *** 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: aeroelectric-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. ************************************** *** Enclosure Support on the Lists *** ************************************** Limited posting of enclosures such as pictures, documents, and spreadsheets is supported on the Lists. There are a number of restrictions, and these are detailed below. Please abide by the rules put forth regarding the content of enclosures. These are some of the features and limits of enclosures on the Matronics Lists: 1) Enclosures will only be posted to the Real Time version of the Lists. 2) Enclosures will NOT be included in the Daily Digest version of the Lists. 3) Enclosures WILL BE forwarded on to the BBS Forum Web site. 4) Enclosures will NOT be appended to the Archives. 5) Enclosures will NOT be available in the List Browse feature. 6) Only the following file types and extensions will be allowed: bmp doc dwg dxf gif jpg pdf png txt xls All other enclosures types will be rejected and email returned to sender. The enclosure types listed above are relatively safe from a virus standpoint and don't pose a particularly large security risk. 7) !! All incoming enclosures will be scanned for viruses prior to posting to the List. This is done in real time and will not slow down the process of posting the message !! Here are some rules for posting enclosures. Failure to abide by these rules could result in the removal of a subscriber's email address from the Lists. 1) Pay attention to what you are posting!! Make sure that the files you are enclosing aren't HUGE (greater that 1MB). Remember that there are still people checking they're email via dial up modem. If you post 30MB worth of pictures, you are placing an unnecessary burden on these folks and the rest of us, for that matter. 2) SCALE YOUR PICTURES DOWN!!! I don't want to see huge 3000 x 2000 pictures getting posted that are 3 or 4MB each. This is just unacceptable. Use a program such as Photoshop to scale the picture down to something on the order of 800 x 600 and try to keep the file size to less-than 200KB, preferably much less. Microsoft has a really awesome utility available for free that allows you to Right-Click on a picture in Explorer and automatically scale it down and resave it. This is a great utility - get it, use it! http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx Look for the link "Image Resizer" 3) !! This would seem to go without saying, but I'll say it anyway. Do not post anything that would be considered offensive by your grandmother. And you know what I'm saying; I don't want to see anything even questionable. !! 4) REMEMBER THIS: If you post a 1MB enclosure to a List with 1000 members subscribed, your 1MB enclosure must be resent 1000 times amounting to 1MB X 1000 = 1 Gigabyte of network traffic!! BE CAREFUL and BE COURTEOUS! Also see the section below on the Matronics Photo and File Share where you can have your files and photos posted on the Matronics web server for long time viewing and availability. ******************* *** 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 "aeroelectric-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 AeroElectric-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.

Every year during November I run a low-key, low-pressure "Fund Raiser" where, throughout the month, I ask List members to make a Contribution in any amount with which they are comfortable. 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. If you enjoy and value the List, won't you make a Contribution today to support its continued operation? http://www.matronics.com/contributions Thank you!

You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the AeroElectric-List in the manner described below may result in the removal of the subscribers from the List. AeroElectric-List Policy Statement The purpose of the AeroElectric-List is to provide a forum of discussion for things related to this particular discussion group. 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.] do not archive
