Maximotors were built by Max Dingfelder in Detroit, Michigan, around 1911 to 1913. Models included four- and six-cylinder in-line and V-8 water-cooled engines. This 52 kw (70 hp) Model B-4 Maximotor was the last of several that powered Thomas S. Baldwin's Red Devil III aircraft. Maximotors were used on aircraft such as those built by Wright, Curtiss, Bleriot, and Farman and Antoinette.
