The origins of the Stinson 108, called “Voyager”, trace back to the early 1940’s. It was at that time that Stinson Aviation took their popular pre WW II model and used it as the basis for a new aircraft.
The first of the new aircraft retained the three place seating arrangement of its predecessor. The fuselage was stretched by approximately 24 inches and it had a more powerful engine.
Subsequent Stinson 108 models used metal tail fins instead of wood. The horizontal stab was relocated to a higher position. They provided seating for four, even more powerful engines, lengthened the fuselage an additional foot, and increased the width of the cabin.
The purpose of the new Stinson 108 was to provide comfortable transportation for up to four people across relatively long distances. Prior Stinson aircraft were set up for shorter distances and often thought of as trainers.
Later some Stinson 108 aircraft were even fitted with pontoons. Newer models continued to have power upgrades. Some had stronger floors and a door to access the baggage compartment, plus additional cargo capacity.
More improvements followed including a larger tail group with rudder trim now adjustable in flight. Gaps were installed across the wing’s leading edge to coincide with the positioning of the ailerons on the trailing edge of the Stinson 108 wings. These permit the aircraft to remain in controlled flight at slower speeds and with its nose held higher than normal.
Flying the Stinson 108
Taking off is as simple as lining up the airplane with the center of the runway and advancing the throttle.
Although the Stinson 108 has a reasonably sized engine, there is a bit of mass to get into the air. Prop wash will get the tail up quickly and the aircraft will float into the air soon thereafter. If the wind is pretty much straight down the runway, minimal rudder is necessary to track straight.
The climb rate of the Stinson 108 is rather leisurely. The controls are very smooth and light. It is an easy to handle, stable aircraft. Stalls are light and controllable. Cruising at 124 mph will result in about a 10 gph fuel consumption rate.
Depending on who you talk to, landing the Stinson 108 can be interesting. A slow approach will result in a fast loss of altitude and the need to apply power for a proper flare, all while the aircraft is under total control. Waiting until the last moment to apply throttle will keep the roll out short, and the landing exciting. A plus is that the landing gear struts tend to smooth out less than perfect touch downs.
Over 5,260 Stinson 108 aircraft were built before production ended in 1950. You can find a Stinson 108 for sale in good condition to this date.
