The Stits SA-3A Playboy (also called the Stitts SA-3A Playboy) is a single seat strut-braced low-wing monoplane that was designed by Ray Stits for amateur construction. The aircraft was designed and the prototype was completed in a three month period during 1952. The design went on to become one of the most influential in the post-war boom in aircraft homebuilding. A side-by-side two seat version is known as the SA-3B.
Stits Playboy is the predecessor of the Van's Aircraft RV-3.
