P.F. and Don,Like Brian has said and others agree, thanks for doing the study. I know that itrequired a great deal of time on both your part. I, for one, found it interestinghow the comparison turned out, but I think you said it best when you said-"Which airfoil do we recommend? Thats the builders choice. Either one will work."And I think that that is the message of your study- choose the one that you want,and be comfortable in the fact that they both work well.Thanks again for your hard work and desire to share with the rest of us.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 21 Mar 2013 19:53:06 -0500Subject: Re: Pietenpol-List: Need a good A&P for condition inspection

Pietenpol-List: Re: Second update on comparrisen testing of Pietenpol

P.F. and Don-I wouldn't say that there is little to no benefit of using the Riblett. Here'sa snip from a post that I made in May of 2008 on the subject:"The Riblett "612" airfoil is very similar to the NACA 4412 airfoil that has also been discussed here. Both of those airfoils are deeper than the Pietenpol, allowing for lighter spars and ribs, increased volume where a fuel tank can go in the wing, and both of them have less undercamber than the Pietenpol airfoil. With a 60" chord, a 12% airfoil is a bit over 7" deep as compared with the Pietenpol at 4" deep. There is an image of the NACA and Riblett airfoils at http://www.flysquirrel.net/piets/airfoils.jpg"By the way, I echo the questions that Dan Yocum asked, especially- did you by anychance check stall speed with both airfoils?--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 21 Mar 2013 20:37:48 -0700
