Subject: Pietenpol-List: Engines and Mounts I don't think Continental ever built a 'C65' engine. It was an A65, then an A75, then a C85 engine, which is close to the O-200. Recently, there was an article in Sport Aviation about the history of Continental engines. Throughout the history of the Pietenpol, it is notable to have had a wider variety of engines than any other airframe in aviation history. However,there is None that I know of that has had success with a V W engine. In my opinion, the A65 engine is a near perfect match for the Pietenpol Airframe. Asfar as PSRU's (Prop Speed Reduction Units), they add weight, complexity, expense and maintenance...and more notable, they reduce reliability and dependability. You simply can't disregard a trend analyst. An engine mount would almost certainly have to be custom built for any particular homebuilt airplane, or at least modified in some way if you would purchase one. Another huge reason to build your own mount, is that it is a reasonable method to attain a safe Center of Gravity location. Shad is correctin that my engine mount is long, in order to maintain a safe C of G in any loading configuration. I used the next heavier wall thickness tubing than in theplans, and I built it with down thrust, and right thrust. And Gus, I think you should certainly purchase a set of plans from the Pietenpol Family. There is a link to their web site on my home page.Chuck GantzerWichita, KSNX770CGhttp://nx770cg.com/________________________________________________________________________________Date: Fri, 09 Feb 2007 07:27:37 -0500
