The Sapphire is a single-seat racing airplane of all-wood construction designed by Claude Piel. The airplane is stressed for the load factors of +12 and 19 C's at the maximum takeoff weight of 770 pounds. The Saphhire can accommodate any engine from 50 to 100 hp. Its wing is fully cantilevered and tapered for minimum drag and has a tip-to-tip laminated box spar to avoid heavy root fittings and wing alignment problems. The fuselage consists of three bulkheads and is entirely plywood covered. The cockpit is roomy enough to accommodate a large pilot. The landing gear is a fixed tailwheel configuration.
The Cougar is a single-place, high-speed aerobatic monoplane. It utilizes an all-wood design and a 90-hp engine.
In 1980 plans were available from E. Littner, Box 272, SaintLaurent, Quebec H4L 4V6, Canada.
