By April 1941 the Romanians were firmly in the German sphere, and as a result the Germans released more FN guns for their use. These were quickly installed, and the resulting 80A model finally mounted the original complement of six guns. Armored glass in the windscreen, seat-back armor, and a new gun sight were also added at the same time, along with the newer K14-1000A engine. The extra engine power proved to be more than the fuselage structure was designed to handle, and it had to be reinforced with a duralumin "belt" just behind the cockpit in the first 95 A series aircraft built before the fuselage could be modified.
