Stinson 105 / 10-A / Voyager / YO-54 / O-62 / L-5 Sentinel / OY-1
The Stinson Model 105 appeared in 1939 as the Voyager, the production line in Wayne, Michigan.
The Stinson 10-A, also known as the Voyager 90, was a three place high wing monoplane, powered by a four cylinder, 90 hp Franklin 4AC engine, with a fixed pitch, wooden propeller. It received ATC #738 in early March 1941. The Voyager was a new version of the Model 105. It had improved attributes and performance, the cowling had been redesigned and shortened, and along with a newly contoured windshield, provided better visibility. Over 700 of those Voyagers were built in 1941.
The 10-A was equipped with ball-bearing mounted flight controls and leading edge slots. Three position flaps, shock absorbing oleo spring gear struts, 48 inch tread main gear, hydraulic brakes and a steerable tail wheel suited short field work.
The 10-A wings had spruce spars, and the fuselage was welded steel tube. A 20 USG fuel tank was installed in the right wing and another 20 USG tank could be installed in the left wing. The vertical stabiliser was steel, while the horizontal stabiliser was built up from spruce and covered with poplar plywood.
The aircraft had a fly away price of US$3355. The plane was available as a Standard or Deluxe model. The Deluxe having navigation lights, an electric starter and a generator, and bonding for a radio that could be later mounted in its walnut finished instrument panel.
The US Army Air Corps used at least six for observation and liaison in 1942. They were 10-A powered by 90 hp Franklin O-200 engines and designated L-9A. About twelve civilian Model 10-A with 90 hp Franklin 4AC engines were used designated L-9B. Several operated in France.
The Civilian Pilot Training Program used the Voyager for flight training, and the newly formed Civil Air Patrol (CAP) flew the aircraft during coastal patrol missions up and down the East Coast.
At the outbreak of WW2 the 105 became known as the YO-54, the O-62, and finally the L-5.
Stinson Sentinel L-5
The 105 was used by the Army, Navy and Marine Corps. The US Marine Corp operated the L-5 as the OY-1.
Thousands of L-5's were built for the U.S.A.F. during the war, and some were still in service in 1955. Different versions exist, with varying equipment, but all are two-seaters with 185 or 190 h.p. Lycoming O-435 engines.
In 1948 Piper took over the Stinson Division of Consolidated Vultee Aircraft Corporation and acquired the Stinson Voyager production rights, but production of this type was soon halted.
