The original name of the company was Aeronautical Industries Incorporated. In October 1927 the company changed its name to the Warner Aircraft Corporation. In November 1927 the first Scarab radial engine was produced. The Scarab Junior was introduced in 1930. In 1933, the company designed and built a much larger radial engine, the Super Scarab.
