Subject: Pietenpol-List: Aluminum struts-what size?Gentlemen, (and one lady in Italy)I am very happy to report that at long last (7 years +) that I am finally at the stage of buying some wing strut material. I am looking to use aluminum wing struts for the weight savings. In my research I see that there are various suppliers that have this material (A/CS, Wicks, Carlsons, Skytech) in various sizes. Can anyone with experience help me with the selection of materialsize? I have been delinquent on my trips to Brodhead to take any measurements. Engineering types please feel free to chime-in to the discussion.Please help.Dan HelsperPoplar Grove, IL.________________________________________________________________________________

Subject: Re: Pietenpol-List: Re: Aluminum struts-what size?Carson,Those instruments and mag switch are the result of searching on ebay for years. You have to be diligent, be willing to dedicate the money, and also it really pays to have one of those _www.Powersnipe.com_ (http://www.Powersnipe.com) accounts so you can out bid your opponents at the last second automatically. I have 3 compasses in a box that I wasted money on and decidedwere not good enough. I wanted to have one of those Elgin clocks in my panel, and boughta non-working one thinking that I could have it fixed. NOT!. I took it to 3 old-timer clock repair guys and they said forget it. I paid for that mistake.Anyway I used to live in Elgin Illinois for 17 years where they used to have the old factory, so that part of it is personal nostalgia for me. The non-sensitive 4" altimeter is really neat, looks great and works good, but iskind of impractical because I will be flying at 500 ft. AGL and the needle will hardly move. That's OK because when you are at 500 ft you don't need to look atan altimeter anyway. The old 4" tach works but I am having to have a special cable made for it. We shall see how that works. I got a matching set of "book-end" veneer pieces from Bob Morgan's _www.morganwood.com_ (http://www.morganwood.com) . to make the face of the panels. Looks cool with no weight penalty, and its away to customize. Good luck with yours. Dan HelsperPoplar Grove, IL.________________________________________________________________________________

Hi Santiago,I do have a blade drawing of the 2nd prop that she flew with. This prop is an 80x 43 and was designed based on the performance calculation of my Pietenpol,NX3116, it was the 2nd prop I carved.This may/will not be an effective prop for your plane unless your engine is puttingout 57 Hp @ 1600 rpm at cruise, which my calculations were based on. Youneed to be in the peak torque range of the Model-A for the best airplane, engineand prop combination. Using a typical prop off a C-65 will be more efficientat 2200 rpm and well out, and on the down side, of the torque curve for themodel-A. High drag planes, like the Pietenpol, fly best with big slow turningprops moving a lot of air.If you do not increase the horsepower of the Model-A, 37 HP, you will still wantto design a prop to be in the 1600-1700 rpm range and well within the peak torquerange of the engine.It flies better with this combination.Let me know if you still would like the drawing and some pictures of my prop."Keep the Dream"Keri-AnnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 29 Oct 2007 05:35:39 -0700 (PDT)
