Between 1928 and 1929, Al Menasco began developing the first of
a series of inverted, inline air-cooled engines that became his
design hallmark. The advantages of this design included improved
pilot visibility, a high propeller centerline, and streamlined,
low-drag installation. High performance 4- and 6-cylinder
Menasco engines powered many small racing aircraft to victory in
the 1930s. The 200-horsepower, supercharged Model B6S was type
certificated in 1934. A B6S powered the Howard DGA-4 "Mike"
aircraft, which was raced successfully in the Thompson and Greve
Trophy competitions. The engine displayed here powered a British
Miles Mohawk owned by Charles Lindbergh and used by him on
flights in Europe, India, and Asia in 1937 and 1938. Type:
