Even before the A-1s were delivered, the plane was redesigned with Gnome-Rhône 14M radial engines, which were captured in some number when France fell and continued to be produced under German occupation. This engine supplied for takeoff, compared to the Argus at . The Gnome-Rhone radials were also made in versions with opposite rotation for the propeller, and were installed on the Hs 129 with the port engine rotating clockwise and the starboard rotating counterclockwise, as seen from nose-on, thus eliminating engine torque problems.
