Stipa Caproni SC1-R
In 1933 Caproni was testing a new monoplane, call ed the “Flying Barel”, the standard fuselage was replaced with a hollow barel-shaped body that was intended to reduce drag.
The Flying Barel has a 47 t wingspan and wing area of 205 sq.ft.
Engine: Simmonini, 72 hp
Stinson SM-5
The 1929 Stinson SM-5 low-wing, cabin monoplane, registered NX9625 c/n X-11, was possibly a development of SM-3.
It was originally powered by a Wright J-5 engine, later changed to a J-6.
Stinson W
The 1931 Stinson W (ATC 435) was a deluxe version of Junior, priced at $8,995.
Five were built; NC10849, NC12144, NC12146, NC12160, and NC12177.

Stinson Cootie
The 1919 Stout Cootie was a single-place open cockpit, mid-wing monoplane with a thick cantilever wing. The wingspan was about 18 feet. Taken to Morrow Field in Detroit for testing in March 1919, but the 38hp two-cycle Sperry-Wills engine refused to run and the aircraft never flew.
Stinson R / R-1 / R-2 / R-3
The Stinson R / R-1 (ATC 457) of 1932 was designed by Robert Ayer and C R Irvine as a four-place cabin high wing monoplane. A deluxe Junior, and forerunner of Reliant, powered by a 215hp Lycoming R-680 engine, the R-1 was to have a retractable gear added, but was never built.
Thirty R-1 were sold, priced at $5,595, including NC436M/440M, NC446M/448M, NC479M, NC10861, NC10874, NC10876, NC12134, NC12139, NC12147/12156, prototype NC12178, NC12189, and NC12197.
Eddie Stinson was fatally injured in a crash landing of the prototype R on 25 January 1932.
The 1932 R-2 (ATC 489), powered with a 240hp Lycoming R-680 engine, was advertised for $6,497 with retractable gear modification, but none was produced as such. Three were built; NS40, NX447M, and NX12178 modified from R, and possibly one other.
The 1933 R-3 (ATC 493) was the same as the R-2, but with fixed, non-operating prototypical retracting gear. Three were built; NC449M, NC12131, and NC12187, priced at $5,995. Only one was so modified to operating retractable gear as R-3S
The 1934 R-3S (ATC 539) conversion from R-3 NC449M featured a 245hp Lycoming R-680 engine, controllable prop and other improvements.

Stinson 76 Sentinel
The Stinson 76 Sentinel of 1940, designed by A P Fontaine, featured full-span slots, which created a problem during testing with near-fatal results. It first flew on 28 June 1941, powered by a 175hp Lycoming, and piloted by Al Schramm. With modification to half-span slots and enlarged tail surfaces it became final prototype for L-5.
Only the one was built, registered NX27772.
Stinson Amphibian
The 1931 Stinson Amphibian project, very Sikorsky-like, was abandoned after unsatisfactory testing and a wheels-up landing.
It was a five-place, high wing cabin monoplane, powered by two 215hp Lycoming R-680 engines, and registered NX11117 c/n M-7000.
