I prefer to use the polar diagrams (and preferably polars derived from actual wind tunnel studies) when comparing two airfoils. If you overlay the polar for MH32 and SA7036 you will see that the two airfoils compare very closely in performance (SA7036 may have a slight advantage when used at low coefficients of lift [slope soaring/speed task]). Comparing airfoils based on camber and thickness alone is less successful in predicting performance. I suggest you compare the airfoil polars and decide for yourself at http://soaring.cnde.iastate.edu/calcs/frames.shtml >From: "Eddie E." <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]>, <[EMAIL PROTECTED]> >Subject: Re: [RCSE] Re: MH 32 Airfoil >Date: Fri, 17 Sep 1999 13:38:12 -0400 > >I disagree with this last comparison. >The MH32 is much lower in camber than an Sa7036. >In fact it it's lower camber than the 7035.
