I'm no expert on the subject, but my understanding is that the "612" is Riblett's GA30-612 (and modifications thereof). By Riblett's terminology, the "30" means that the maximum thickness occurs at 30% of the wing chord or 18" aft of the wing leading edge for the 60" chord Piet wing. The "-12" indicates that the wing depth (thickness) is 12% of the chord, or 7.2". The stock FC-10 airfoil is about an inch less deep than the 612 and it also has undercamber, which the Riblett does not. Other considerations aside, including performance, a deeper spar can carry the same loads with lighter construction than a shorter one... if properly engineered. A thicker wing section can provide more room for larger fuel tanks or a baggage compartment, if that's a consideration. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=462742#462742 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
