"Motor F.L."

-It was a nice looking engine with two cylinders producing 33 CV at 3,700 rpm. (year 1936).

-It had a four-stroke cycle and valves at 45°, with two carburetors and geared at 0.5. At full speed, the propeller rotated at 1,850 rpm.

-It was tested on a Pou-du-ciel, which was very satisfactory.
