The Stits SA-11A Playmate is a homebuilt aircraft design that features a rapid wing-folding mechanism for trailering or storage.

[1] The SA-11A is a single engine, side-by-side configuration seating, tricycle gear, strut-braced, low wing monoplane.

[2] The wings have a quick release mechanism that allows them to fold and lock alongside the fuselage in 15–30 seconds.

A small sideways seat in the rear can accommodate 150 lb (68 kg) of luggage or a light passenger.

[3] The prototype was donated by Ray Stits in 1969 to the EAA AirVenture Museum in Oshkosh, Wisconsin.
