Parasol

The Heath Parasol is an American single or two seat, open-cockpit, parasol winged, homebuilt monoplane. Design and development In 1926, Edward Bayard Heath, a successful American air racer and the owner of an aircraft parts supply business, built the first example of the Heath Parasol, a small, single seat parasol winged airplane using surplus wings from a Thomas-Morse S-4, a World War One fighter trainer, mounted above a steel-tube structure fuselage and powered by a Henderson four-cylinder motorcycle engine. This was the prototype for a series of single and two-seat recreational craft that utilized the Clark Y airfoil. In 1929 Modern Mechanix magazine published the plans in a series and the plans were reprinted in their "1930 Flying & Gliding Manual," which in turn has been reprinted periodically by the EAA (Experimental Aircraft Association). Although Heath died in 1931 his Parasol designs remained extremely popular, being economical to build and operate as well as easy to fly. Subsequently, the Heath Company of St. Joseph / Benton Harbor Michigan sold nearly 1,000 kits on an installment basis. Fewer than 50 aircraft were factory built, but several hundred were completed and flown by homebuilders during the Great Depression. Heath is remembered today for having helped pioneer the homebuilt aircraft industry and for having introduced the kit concept of packaging the materials needed to build an aircraft.
