The HP-9, the HP indicating high performance, was Schreder's FAI Standard Class follow-on design to the FAI Open Class HP-8 and was built to compete in the 1960 Worlds in the newly established Standard Class, but was not completed in time. The HP-9 was sold unfinished to Bob Litle, Jr who had Javelin Aircraft complete the glider.[1][2]
The HP-9 is constructed entirely of aluminium and has an all-flying stabilator tail. The aircraft also features dive brakes and a retractable monowheel undercarriage. The wing has Fowler flaps which increase the wing area from 127.4 to 143.7 sq ft (12 to 13 m2) and lower the minimum sink speed to 2.11 feet per second (0.64 m/s) at 47 mph (76 km/h) from 2.26 ft/s (0.69 m/s) at 60 mph (97 km/h).[1][2]
Only one HP-9 was built.[1][2]
The sole HP-9 was still in existence in April 2011 and was listed by the Federal Aviation Administration as having been sold to the Center County, Pennsylvania Visitor Bureau.[3]
