HP Aircraft HP-16
The HP-16 involved major changes in Schreder’s HP-15 design, with a different wing similar to the RS-15 of much lower aspect ratio and grater area. The aluminum wing skins are bonded to foam ribs, including rivet use and construction time. The HP-16 retains the very effective 90 degrees Schreder flaps. One belongs to the National Soaring Museum.
