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.
