Here is a link with more info- http://flycorvair.net/2016/02/12/texas-corvair-college-36-april-1-3-sign-up-closes-soon/ Oscar hit the nail on the head. If you are any kind of experimental aviation guy, you will have a great time at a Corvair College. You will make friends with new people, put faces with names of people on this forum, and have a great time in general. Here is a video explaining more about Corvair College, filmed and produced by EAA - http://www.eaavideo.org/video.aspx?v=3971877626001 Here are some videos showing the kind of learning that takes place - https://www.youtube.com/watch?v=l85w6Bk90V4 https://www.youtube.com/watch?v=dt529VT2WHQ -------- Semper Fi, Terry Hand Athens, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=452884#452884 ________________________________ Message 2 _____________________________________ Time: 06:55:46 AM PST US Subject: Re: Pietenpol-List: Re: Corvair College 36 - San Marcos, TX, 1-3 April 2016 From: Steven Dortch Thanks, i sent it to our EAA newsletter ________________________________ Message 3 _____________________________________ Time: 09:56:44 PM PST US Subject: Pietenpol-List: weight & balance From: "taildrags" Okay, so really, builders don't need to be waiting till their aircraft are almost finished before thinking about W&B. In fact, the earlier you start to think about it and start getting numbers in your head, the more confident you'll be about it when it comes time to do the final, actual W&B and fill in the forms that you'll show at the end. Once you have the bare fuselage -covered or not- on the gear, you're ready to start measuring and weighing. At that point you can start plugging some numbers into a W&B spreadsheet and it will be even easier if you don't have the wings or engine on the bare fuselage because you can move it around the shop or hangar very easily. Not only that but if you don't have the cabanes and centersection mounted yet, it will be even easier to get your helper to climb into that front cockpit to do the weighing to get the passenger moment arm calculated. With the fuselage on the gear (as long as the geometry is locked in and the gear mounting brackets are actually bolted to the fuselage or at least pinned in place in final locations), you can determine the various moment arms for the main gear and tailwheel, as well as the moment arms for pilot and passenger. If you're using a nose tank you can also determine the moment arm for it if you have the tank fabricated and can set it temporarily in place in the forward fuselage. All of this can be done with nothing more than masking tape, markers, a string and plumb bob or fishing weight, and a couple of simple bathroom scales since the accuracy of the scales doesn't matter too much at that point. They just need to be reasonably accurate and the readings repeatable, and the actual weights won't matter much in order to determine moment arms. As a starting point I can offer the Excel spreadsheet that I've used for the W&B on 41CC, and I can probably also cook up a simple spreadsheet for coming up with the passenger and pilot moment arms after you've taken some simple readings on a rainy workshop day when you and a helper are able to make some measurements slowly, carefully, and thoughtfully. If you do it right the first time, you'll never have to do it again. The upside to all of this is that if you start the process early, you can make adjustments as you go along and not get surprised at the very end when you find out your airplane has a heavy tail and you have to find a way to offset or move it. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=452912#452912 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
