Perspective

First developed as the Stinson HW-75 and marketed as the Model 105 in 1939, the design 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. This was developed into the Model 10, introduced in 1940, powered by a Continental A-80 piston engine. The Model 10 introduced wider seats as well as an improved standard for the interior and finish.^[1] In 1941 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. Both had a slightly widened cabin. The 10A was the last of the series, but the first to be called "Voyager", a name that was retained for the post-war Stinson 108.^[2]

Six Model 10s were evaluated by the United States Army Air Forces (USAAF) as the YO-54 in field trials held between September 1940 and January 1941. Deemed unsuitable for artillery observation, no further examples were ordered, although the military later purchased 12 model 10A Voyagers in 1942 for domestic use as couriers. In the meantime, Stinson created the Model 75B, a one-off 100 hp tandem seat version of the Model 10 that first flew in June 1940. Re-designated as the Model 75C with a 125 hp engine, the military rejected it as being under-powered and too fragile for combat use. This led Stinson to design an all-new aircraft designated Model 76, later known as the L-5 Sentinel that conformed to Army/Navy engineering handbook standards.^[3]^[4]

The twelve Model 10As were civilian-owned aircraft re-purchased by Stinson and sold to the USAAF who pressed them into service as the L-9B.^[5] Other sources state they were originally designated AT-19 but this has not been verified and is probably incorrect as this was the military designation for Stinson's model SR-10.

After World War II, the type was developed as the 4-seat Model 108, the prototype being a modified Model 10A.^[6]
