The Reliant is a three-place high-wing fixed tailwheel land monoplane powered with a variety of radial engines.
1,327 Reliants of all types were made from 1933 to 1941, in different models, from SR-1 to SR-10. The final commercial model, the Stinson Reliant SR-10, was introduced in 1938. A militarized version was first flown in February 1942 and remained in production through several additional versions (all externally identical) until late 1943 for the US and British armed forces.
Reliant production can be broken into two distinct types - the straight wing Reliants (all models up to SR-6) and the gull wing Reliants (all models from SR-7 and after including the militarized V-77/AT-19) with there being little in common between the two groups of types. The straight wing Reliant had a wing of constant chord and thickness which was supported by two struts each side with additional bracing struts. In contrast the taper wing Reliant had 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. The taper wing had a significant step up between the fuselage and the wing, and the changes in wing thickness gave it a distinct gull appearance from the front
