You Piet guys are probably going to blackball me from this list if I don't cut the chatter, but I thought it worthwhile to pass along two more anecdotes from William Wynne.One relates to performance due to wing incidence. He told me of a Corvair-powered Piet that was performing poorly, and he was asked what might be wrong. Turns out that the builder had swapped the front and rear cabanes when mounting the wings, so it had negative incidence on the wing! I don't suppose it would perform well that way, and sure enough it would cruise with the nose high and didn't have enough elevator control in the landing flare. But it sure wasn't the engine's fault.The other has to do with how the Corvair stacks up against... a 145 Warner! Some of you may have seen the round-engined Warner Piet at Brodhead or elsewhere. The Warner is said to develop 145 HP at 1700 RPM or something like that, and this one has a heck of a climb prop. So William says it easily out-climbed his Corvair-powered Piet but he could overtake it in cruise.These Pietenpols are great, aren't they? Stout, forgiving, easily "customized", and just plane fun ;o)Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Fri, 06 Dec 2002 14:12:13 -0500
