Don't panic. I noticed I forgot the sheer web in right wing and fixed it.
The full-scale Heath Racer was built by the Heath Aircraft Corp. of Niles, Michigan from 1932 to 1936. Its wing span was 18 feet, 2 inches compared to 26 feet, 10 inches for the standard Heath Center-Wing. The engine was a Continental A-40. The plane was raced in the 115 cubic inch class in 1933, as reported in The Golden Age of Air Racing, by Schmid and Weaver (EAA Aviation Foundation, Oshkosh, WI 54903).
Its similarity to the more famous Heath Parasol is quite evident as the shape of the wing trailing edge is a dead give away. The more publicized Church Midwing is actually a well modified Heath Midwing. The original plane was built in 1933 and was granted ATC 495.
