I want to hot wire the 18% tapering to 15% but only four feet at a time. how do i come up with the middle airfoil? if the section was 8' what would the 4' airfoil be, 16.5%? do i take the 15% and 18% airfoil and average the size between them in cord and curves? thanks jerry > >Message: 3 >Date: Mon, 08 May 2006 09:21:42 -0500 >From: Steve Eberhart <st...@newtech.com> >Subject: Re: KR> Spar wood >To: KRnet <kr...@mylist.net> >Message-ID: <445f53f6.80...@newtech.com> >Content-Type: text/plain; charset=ISO-8859-1; format=flowed > >I am not sure, from reading all of the posts in this thread, if a >constant 18% thick wing is what is being discussed here or an 18% >tapering to 15%.
