I bought my GN-1. I have a set of GN-1 plans. The printed plans call forthe front and rear cabanes being equal. Someone hand wrote that the rearshould be 1" shorter with a 2 degree angle of incidence. Someone atBrodhead pointed out that the rear should be shorter. My plane does fly alittle tail low.Any thoughts or clarification?Ted________________________________________________________________________________

A GN 1 is NOT a Pietenpol. A Pietenpol has a slightly reflexed wing withpractically no nose down moment. A GN 1 has, I believe, a Cub wing, orsimilar, that has nose down moment. Don't start changing wing setup until youunderstand why you're doing it. On a Piet, changing the angle of incidenceshould not change the nose down moment (it won't make any difference in yourplane being tail heavy). I don't think it will on your GN1 either. It maymake it fly better, or worse.Where is your CG. Investigate that if tail heavy.MikeBellColumbia,SCMaiser(at)adena.byu.edu on 08/12/99 09:35:22 PMPlease respond to piet(at)byu.edu @ INTERNETcc:Subject: Pietenpol-List: Re: GN-1 Cabanes>I bought my GN-1.

Ted-As far as I know, the Cabane struts on the GN-1 are equal front and rear. The Pietenpol struts are 1" shorter ...The weight and balance could be your problem....try a 50 lb. weight in the front seat while flying solo.Steve________________________________________________________________________________
