CP.80 Zephyr

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, Saint Laurent, Quebec H4L 4V6, Canada.

Piel Aviation Sa
Avions Claude Piel

Claude Piel produced a series of light aircraft from the early 1950s, most famous of which was the Emeraude two-seater with, in its original CP.30 form, a 65 hp Continental engine. Hundreds of Emeraudes of varying types were built under license by companies in a number of countries. This company (instead of original Piel Aviation SA) continues to market Piel aircraft in plans form, including single-seat CP.80 Zef racing monoplane, CP.90 Pinocchio single-seat monoplane (single-seat variant of Emeraude), CP.328 Super Emeraude (also has been commercially built), CP.402 Donald single-seat high-wing cabin monoplane (first flown 1953), CP.605 Diamant three/four-seat cabin monoplane (first flown 1964 in CP.604 prototype form) and is certificated for commercial production, CP.751 Beryl tandem two-seat monoplane, and CP.1320 Saphir three-seat monoplane.
An aeronautical engineer, he designed a complete family of aircraft. Claude Piel died in August 1982.
