The Stinson Voyager was a 1940s American light utility monoplane built by the Stinson Aircraft Company. First developed as the Stinson Model 105 in 1939, the Voyager was a high-wing three-seat braced monoplane powered by either a 75-hp (63.4-Kw) Continental A-75 or an 80-hp (67.7-Kw) Continental A-80-6.[1] This was developed into the Model 10 powered by a Continental A-80 piston engine. The Model 10 introduced a wider cabin as well as an improved standard for the interior and finish. The Model 10 was followed by the Model 10A, powered by a Franklin 4AC-199 engine and the Model 10B with a Lycoming GO-145. Six Model 10As were evaluated by the United States Army Air Forces (USAAF) as the YO-54. The successful tests led to an order for the slightly larger and heavier O-62, later designated the L-5 Sentinel. A number of Model 105s and Model 10As were impressed into USAAF service as the AT-19 (later L-9). After World War II, the type was developed as the Model 108, the prototypes being converted Model 10As. Variants.
