The Stinson Reliant is a popular single-engine four- to five-seat high-wing monoplane manufactured by the Stinson Aircraft Division of the Aviation Manufacturing Corporation of Wayne, Michigan.

The Reliant is a high-wing, fixed-tailwheel land monoplane powered with a variety of radial engines.

In contrast the taper-wing Reliant has the broadest chord and thickness of the wing at mid-span, with the outer wing trailing edge heavily angled forward and a rounded cutout on the leading edge root, all supported by a single strut.

[citation needed] The Reliant was used by the United States Army Air Forces in World War II as a utility aircraft, designated UC-81, and as trainer designated AT-19.

Internal structure was beefed up significantly over the commercial models, and a distinctive triangle-shaped counterbalance was added to the rudder.
