Remarks by Walter van Tilborg: "The CH-200 Zénith was an original design all-metal two-seater of Christopher Heintz, the former Chief designer of Avions Robin, and the type was intended for amateur construction. The first CH-200 built by designer with an 100 hp Rolss-Royce/Continental O-200-A engine and first flew on March 22, 1970. The type became popular among amateur builders for engines in the 85 to 160 hp range and was initially available with a centrally-mounted stick or with full dual controls (suffix M in designation) and a choice of an all-flying vertical tail or conventional tail/rudder (suffix F), or with both options (suffix FM).

Many CH-200 aircraft were built and especially in France a variety of designations was used to identify the aircraft, which often had detail changes and/or modifications developed by the builders. The name Zénith was usually given to homebuilt aircraft, irrespective of engine type and horsepower while the designer's designation CH-200 was not often used (except in North America)."
