The Stinson Reliant SR is a classic American cabin monoplane built by the Stinson Aircraft Company during the 1930s, with SR series production running through the prewar years into 1941. It was designed as a private and business aircraft, positioned above basic trainers and open cockpit sport aircraft of the era. The type is best known for its radial engine, enclosed cabin and distinctive high wing, with later SR models adopting the recognizable gull wing planform. For buyers, the Stinson Reliant SR matters because it represents a usable antique aircraft rather than a purely static collectible, with comfortable cabin access, good short field manners and strong period character.
Performance depends heavily on variant, engine installation, propeller and restoration standard. Typical Stinson Reliant SR cruise speeds are commonly in the 105 to 120 knot range. Published ranges for many SR models are generally around 450 to 600 nautical miles, subject to fuel capacity and power setting. Useful load commonly falls near 900 to 1,100 lb, again varying by model and equipment. Service ceiling figures for the series are typically in the mid teens, with many references listing values around 14,000 to 17,000 feet. Powerplants across the SR line include radial engines such as the Lycoming R-680, Wright R-760 and Pratt & Whitney Wasp Junior, depending on the specific SR variant.
The Stinson Reliant SR generally offers seating for four or five occupants in an enclosed cabin, with broad doors, upright seating and better weather protection than many earlier light aircraft. Cabin finish varies widely, since most surviving examples have undergone at least one major restoration. Original aircraft were delivered with period flight instruments and basic radio equipment, not integrated glass avionics such as Garmin Perspective or Garmin G1000. Aircraft on the used market may have discreet modern upgrades, commonly including VHF comm, transponder, ADS-B Out, portable or panel mounted GPS and updated engine monitoring, often installed with attention to preserving the vintage panel appearance.
Prospective buyers should identify the exact SR variant, engine type, airframe history and restoration quality before comparing prices. Important inspection areas include wood structure, fabric condition, corrosion in fittings and landing gear attachments, radial engine health, propeller status and documentation of any major repairs. Common value drivers include originality, quality of fabric and interior work, engine overhaul time, approved avionics upgrades, and whether the aircraft has been maintained by shops familiar with antique radial aircraft. In the used market, the Stinson Reliant SR is typically positioned as a premium vintage cabin aircraft, appealing to buyers who want 1930s design, practical seating and authentic radial engine operation rather than modern speed or avionics integration.
