    Facebook Avid Group is doing well. It is a shame because Facebook is a very poor interface for technical exchange, I can only imagine what it takes to conduct an annual inspection based on a piece of advice you got from an anonymous source on Facebook! On the other hand avid fox flyers is a terrific source, library, searchable database.

    This is mostly because of you folks and how open you are to questions and suggestions and how well you document what your answers with photos and videos. the library of searchable threads of photographs and discussions from expert people who have done the job before is just terrific.

    I have sent perhaps six or seven people from Facebook to the site and gotten emails from each one about how difficult it is sign up. Apparently our software doesn't even recognize some mail servers so the people who use to those mail systems cannot get their membership request email read. They the beat on the door for about two weeks and give up. None of this is criticism of the site editors and administrators, who are doing a great job, and also are not IT gurus. But it is a criticism of our overall system if we can't seem to get new members.
    When I bought my airplane from Jim Peet I had dozens of people helping me make decisions, helping me check out and feel comfortable with my machine. What our neighborhood this is! I think we need to look carefully at how we get more members to come here because this is far superior to Facebook and the other social media.

    Looped,
    Let me try to explain the hill any new owner must climb:
    there are two pieces of paper that your airplane needs, an airworthiness certificate and a registration. The previous owner did a disservice by not providing the Airworthiness Cert, now you have to establish it from scratch for the FAA, each component and the build process. If you are an A&P it is possible, for a regular guy I thing it is a genuine PITA. Frankly, the airplane is worth 50% without the airworthiness cert.
    Try and talk the owner into providing the AW and also offer a legal release (EAA has them on the web site) because often the families are told by local lawyers who don't know beans about airplanes that they cannot sell an airplane, so pulling the AW and the registration supposedly make them immune legally. 
    Registration is very easy, it is a simple form.
    The EAA says nobody has ever won a law suit over an experimental airplane, the jury will be told what experimental means.

    The spec they show states both drawn and extruded, so I bet they could provide either. Also, I emailed them and they can provide T6 heat treat. 
    Some sources I found say that extruded is probably stronger because the surface should be smoother with fewer stress risers, but I would defer to your more specific knowledge.

    I note Jim that it doesn't specify T6 heat treat. I'll email them to see

    Wing .083" Spar Vendor Found
    I found this supplier, Metal Supermarkets, and got a very reasonable quote for .083" wall spars for our Avids and Kitfoxes, less than $100 apiece. They are FOB in Utah and Texas, it seems.

    Duke/Mark makes a great point, the Rotax 670 has 92 horsepower, but is only about 10-15 total pounds heavier than the 582. I believe this is many pounds lighter than the 912. I installed a 670 in my Mark IV and have detailed data on it, as I am sure Dan does. Don't hesitate to reach out. 
    Here is a link to the many posts on the 670 that I made a few years back:  New 670 Engine Install and performance:

  10. nlappos added a post in a topic Weight and Balance Issues, Ballast.   

    Let me recommend a possible rope out of the tree. You can get airworthy by temporarily ballasting within the 14.28" aft cg, and then flight test your way back to the 16.0" I believe the larger horizontal tail and vertical tail will let you go farther aft because you will have more horizontal tail volume to control the aft cg.
    So temporarily ballast to 14.28" with weights hung on the engine mount. Then during the initial 40 hours test further aft by reducing the weight as you test the critical conditions (slowing to unaccelerated stall, landing flare, cruise speed longitudinal stability).
    All legal and all wise.
    How much bigger is your horizontal stab?

    Gerry Visel,
    I changed my starter the last time by going into the box behind the panel, and it worked!

    The Skytrax gearbox has several available ratios, including 3.45:1. It is relatively proven and available, might get rid of a bunch of engineering problems in one easy solution.
    I am an aerospace engineer, and I think coming up with a reliable belt reduction at those rpms is a real challenge.

  13. nlappos added a post in a topic Aircraft registration problems   

    I think you are referring to block 15 "Aircraft manufacturer" where you put in the "assembled from parts".  The actual answer is that you are the manufacturer. Just put your name and as aircraft type "Avid Flyer". At least that's wat my registration has.

    Brian, thanks for the clarification. It is amazing that that nice looking aircraft is so light!
    Here in the Cedar City area the Wx is great, except a bit windy lately. I know all about that "if they are shooting at you" part, my best war stories involve North Vietnam's finest!
