The Continental A65 is a piston engine from the manufacturer Continental Motors Corporation , which has been used as an aircraft engine in light aircraft since the 1930s .
history
In 1931, Continental introduced the A40 with an output of 38 hp as the starting model for a series of small aircraft engines. The A40 was followed by the A50, A65, A75 and A80 versions, all of which were designed as four-cylinder boxer engines . The type number indicated the approximate performance in hp. By the outbreak of World War II , 8,000 copies had already been produced.
After the end of the war, the modified types C75, C85, C115, C125 and C140 were introduced, the last three models being six-cylinder engines. The C140 had a reduction gear as a special feature.
The A65 became the standard engine of the US Army Air Corps for use in all light liaison aircraft of the "Grashopper" type, e.g. B. the Taylorcraft L-2 , Aeronca L-3 and Piper L-4 . For this the A65 was given the military designation O-170 .
