Bill,WOW -- YOU GOT IT -- IT IS A TYPO -- WAY TO GO -- I should have picked that up. Now my airplane matches the design example weights. The computations on the plans are still bogus, but when done correctly the results match mine and the design c.g. range. My aft c.g. problem remains, however. Like I said previously, the design specified aft c.g. limit of 34.5% is well aft of my comfort zone. These plans have been a nightmare of errors.Thanks,TomOn Jul 1, 2008, at 11:25 AM, Bill Church wrote:> Tom,>> I have read that the new CAD drawings for the GN-1 have quite a few > errors.

And don't forget to get your own iron, too. You can bet that if you borrowhers, she'll want one twice as expensive as a replacement!Gary BootheCool, Ca.PietenpolWW Corvair ConversionTail done, working on fuselage(10 ribs down.) _____

For what it is worth; Fair disclaimer, the plane has not yet flown. I did my first covering job on the piet wings and used the 1.7 based on the math and comparison to Grade A cotton. So far the process went flawlessly. It wasn't a matter of money, Valhala knows I have spent twice as much to build my Piet as most folks ordering all new and many PMA parts and not risking anything. I just compared it to what Piets were born with and it came out nicely. I followed the Polyfiber STC practices to the T and my inspector had nothing bad to say, in fact after I saw the random beard hair trapped under the fabric despite the tack cloth treatment I wanted to throw a match on it. But my inspector said he would swear it was an old timer's job. Not tooting my horn, just relaying that the 1.7 didn't raise any red flags yet. -Scott ----- Original Message -----
