Schreder HP-14


The HP-14 is a Richard Schreder-designed all-metal glider aircraft that was offered as a kit for homebuilding during the 1960s and 1970s. It was originally developed by retrofitting improved wings to the fuselage and tail of the HP-13. Schreder won the 1966 US national soaring championship in the prototype HP-14.
The HP-14 features a folding V-tail and 90-degree flaps for glidepath control. The fuselage and wings are of all-aluminum riveted construction.

Development

Development of the HP-14 was carried out by several parties but the biggest modifications to the design were carried out by Slingsby Aviation at Kirkbymoorside, North Yorkshire, England, where a 20-metre wing was fitted on the prototype HP-14C, along with an enlarged V-tail. Later Slingsby production aircraft had a conventional cruciform tail. Slingsby production and sales were hampered by certification problems, particularly with flap actuation at high speed, and the disastrous fire at Kirbymoorside on 18 November 1968. Slingsby produced only three aircraft. Other homebuilders incorporated their own modifications but none achieved production status.
