Al tho the 801 is a bit on the twitchy side due to the fact it is an experi mental and the design doesn't need to be "toned down", read, stable plat form the FAA requires for certified planes so low time and marginal pilo ts can fly them. The flaperons are full span and they introduce roll qu ite easiely but not so much as to become a poor IFR bird.....

I'm building an 80 1 and I'm at the point of making some panel decisions. I'm Instrument rate d, and previously built a Series 5 Kitfox with an IO-240B. I built the plan e with a complete IFR panel. Reality turned out the Kitfox, is too much of a hands on airplane to use as a good IFR platform, so I never fly it IFR. It is a very fun plane to fly though, but tires you out on a long flight from the constant little off course nudges you get from every little bump in flight. So I'd like some honest opinions about how solid is the 801 in flight? Is it Cessna 172 stable, or does it require a lot more pilot attention?

First let me say that the shape of an extrusion has nothing to do with its alloy. So, what the inside corners look like means nothing at all. To prove this I have aluminum angle with inside corners of both varieties in several different alloys to include 2024, 6061, 6063, 7075 & god knows what else. The only thing that specifies the alloy is the markings on the extrusion from the mill specifying the alloy. unfortunately this writing is often unreadable and or washed off. At this point nothing short of a chemical analysis from a metallurgical laboratory can tell you definitively what it is. Structural and Architectural are a slang terms and have no meanings what so ever. This is why we use specifications like ASTM, SAE, AN or MIL -SPEC#'s and so on. these specifications have very specific definitions and limitations. It is entirely possible to build a structure out of an angle with non- filleted inside corners and of the 6063 alloy. Therefore the angle would, by definition be structural. Hopefully this is not an aircraft structure! What is readily available in your area also has nothing to do with alloy or extrusion shape. It only shows what readily sells the best in you area, and therefore that is what the retailers in your area stock. The Angle that Zenith supplies with their kits is 6061 t6. It has 90 degree inside corners. It is readily available in Canada and most of Europe. It is also readily available in the US if you know where to look and you are willing to buy the minimum quantity which is surely more than you will want for one airplane. This extrusion shape is popular in the aircraft industry and is available in most air craft alloys. as I said before; I purchased a fist full of angle form the Boeing surplus store some time back and it all had the square inside corners and was of various alloys. The 6061 t6 Angle that most of you scratch builders are substituting for your wing spars is an extrusion that is common to the US in most every other industry with its filleted inside corners. This extrusion is mildly stronger and mildly heavier. The critical thing is to be sure of the alloy and only use 6061-t6 for your wing spars. If you can read the alloy specification on the piece you can't be sure what the alloy is. -------- Brady McCormick Poulsbo, WA www.magnificentmachine.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219094#219094 ________________________________ Message 4 _____________________________________ Time: 11:53:20 AM PST US Subject: Zenith701801-List: Re: 6061-T6 From: "Brady" Zed, Be careful that you are reading the Mill print on the piece of aluminum and not the sticker some one has stuck to it. See my reply to the "From 2003 and Mark T" post. Home Depot is not a reliable source as you may well know. :) -------- Brady McCormick Poulsbo, WA www.magnificentmachine.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219098#219098 ________________________________ Message 5 _____________________________________ Time: 12:34:51 PM PST US From: Zed Smith Subject: Zenith701801-List: Re: 6061 Txxxxx Brady, Thanks, and you'll recall that I did boldy promote the use of 'disclaimers' throughout my piece on Home Depot. Yes, I am always watchful as to mill markings vs. after-mill stickers. Again, the 'disclaimer'!! Point of my tome was that those needing aluminum angle for all those little fun things one does when 90% done and 90% left to do may benefit from strolling through their local box store to see what is available. It is entirely possible to hit a home run. As to the non-aircraft grade stuff.....regardless of what it is called, there is some angle sold at some of these places that has a 'grainy' structure somewhat akin to mortar sand. You'll see this really quick when attempting to drill a small hole. Stuff flakes out like drilling into granite. It is also brittle, and breaks rather than bends. Probably made from the dross raked off the melting pot where they make real angle. Regards to all, It's FRIDAY!!!! (at least here, anyway.

Also these articles address some of the more common engine issues and some of the ways in which we address them. This section is called Tech Talk and is where we will post all of our Products Testing Data. The articles are written by "Uncle Mike" because he is a far better writer than I am and his engine building experience goes far back to the days of Flat head engines and probably back to the days of wooden spokes though he won't admit it. Smile The First Forged 4340 crankshaft sample is now in an engine case with a cam shaft and will be running before too long. This engine will be equipped with our entirely NEW rotating assembly as well as the rest of our newest products. The first set of all aluminum Nikasil Cylinders will be installed and tested on this engine as well. We will have this engine at the upcoming Corvair College #13 being held In Livermore, CA. For further details of the Corvair College #13 event see www.flycorvair.com or www.flaglvk.com Thank you, -------- Brady McCormick Poulsbo, WA www.magnificentmachine.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219114#219114 ________________________________ Message 7 _____________________________________ Time: 02:33:46 PM PST US Subject: Zenith701801-List: Re: Attention Corvair Builders From: "Stefan" How about a tech note on the 5th bearing?
