Rick noted->It did take care of the problem of the cables going slack,>but I still have some uneven cable tension.Here"s a little excerpt from Chet Peek's book, "The Pietenpol Story":"May 20, 1929. As Bernard Pietenpol opened the throttle of his new Model A powered monoplane, he felt a welcome surge of power." "After a few circuits of the field, he glided in to a smooth landing. As he taxied up to the waiting Don Finke, he must have thought, 'At last I've got the plane I want, a two place that flies good and has plenty of power.'"That airframe, wing, control horns, and basic design came from Mr. Pietenpol's mind and hands over 80 years ago. I fly that airframe, wing, control horns, and basic design every weekend. I notice no ill effects from a little uneven cable tension and I don't think you will, either. However, if you want to work on eliminating it, carry on. I've done studies of the control horn geometry and travel arcs in AutoCAD myself, but then I just turn off the computer and go fly.Oscar ZunigaSan Antonio, TXmailto: taildrags@hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

Oscar,I couldn't agree more with you. I have and anybody else that has built to planshas cable slack at some position of the controls. As nearly 80 years of usehas shown it means nothing. But then, I'm a real proponent of the plans design!I'm very slowly starting the restoration of a '39 Aeronca Chief 65C so I thoughtI'd try to learn some Aeronca history. I got the book "Aeronca's Golden Age"and "Aeronca, A Photo History". The C-2 was Aeronca's first airplane. It wasdesigned by Jean Roche in the later 20's and the design was sold to the alreadyformed but productless Aeronca company. The C-2 was single place and quiteodd looking. It was available from the Aeronca factory for $1495, around 1930.Roche was a recognized aircraft designer working in the field up to thedesign of the C-2. He had a degree in mechanical engineering. Mr. Pietenpolon the other hand had his formal education in his mechanic shop and on the farm,in isolated MN. He somehow came up with a design at the same time that I thinkwas far superior to Roche's and accomplished the same thing but in a muchbetter way, and with an extra seat to boot! He would build one for a customerfor about $675. How Roche's design went into production and Pietenpol's didn'tis beyond me. I guess Mr. Pietenpol was way too humble for what he designed.Anyway, as I tell everyone that I get to talking Pietenpols with, try tostick as close to the plans as possible and don't add extrs STUFF! Just my humbleopinion though. Ha.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 4 Jan 2008 13:32:05 -0800 (PST)
