Tony Bingelis addresses this in one of his books with a graphic that shows an angular relationship between the axle, the wing leading edge, and CG (I believe), and gives an acceptable range for this angle, to give good handling. Chris- you have Tony's books all committed to memory- is it "Sportplane Builder" where I saw this? Of course there are many other factors involved, but this graphical "check" can help identify an obvious problem with axle placement.One unrelated issue that I have yet to see an answer to is the forward limit for CG on the Piet. The aft limit has been clearly defined, but not the forward limit (that I've seen). My guess is that the way pilots are aware of flying at or near forward limit is that they run out of back stick at flare. Anyone have any practical experience (or know of a stated forward CG limit)?Oscar ZunigaMedford, Oregonmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Mon, 14 Jan 2002 08:51:49 -0600
