Designed by C. G. Taylor (who also developed the Taylorcraft line), the Cub series became the most recognized light airplanes in the United States. Used mostly as primary instruction aircraft, these two-place tandem machines earned a reputation for excellent cost efficiency. The first major production model, the E-2 Cub, was an uncomplicated 65 mph parasol. Although most E-2’s were powered by a Continental A-40, there were other engines used, including the little nine-cylinder open-valve Salmson radial manufactured in France (on the prototype E-2 only). The E-2 can be identified from its successor, the J-2, by its parasol layout, its square tail feathers, and many other minor differences. The Continental A-40 powerplant used on this airplane had but one magneto, so the “mag switch” only had two positions, “on” and “off”. The fold-down door, popularized on the E-2, was designed into the entire two-place Cub series, ending more than 60 years later with the Piper PA-18 Super Cub.
