The Schreder / Slingsby HP-14
This is not inteneded as documentation for the HP-14 as this has been adequately covered in depth by Soar Idaho. If that article should disappear from the internet, you can download a pdf copy here In support of this article, Jim Owen has kindly donated his drawings for a scale model of the HP-14 in both the V-tail and T-tail versions of the glider and are available for download from this site further down the page. A Brief History of the HP-14 "In the HP-14 Dick Schreder made improvements to he HP-11/13 fuselage. The Wortmann airfoil wings were mated to the improved fuselage. In the HP-14 Dick Schreder used lower wing loading and reduced aspect ratio, aiming to create a potent Open Class sailplane that would do well in weak conditions. He succeeded admirably: more than 40 all versions were built in the U.S. and Slingsby in England. The ship has appeared with all three tail styles: the original had the familiar Schreder Vee-tail, Slingsby produced the C version with conventional tail, and the final T version used the C wing and a T-tail appeared in 1968. Slingsby HP-14's received type certificates and are licensed in the standard category; the rest are experimental. Hp-14's are famous for the effectiveness of their flaps for landing, and Schreder produced them in kit form from 1966 to 1970. "
