IMPA products included a prototype RR-11 two-seat cantilever low-wing cabin monoplane. The sole example of this was built in 1942 by its designer Alfredo Davinz Ferrer.
The initiative had come from the founder of IMPA, Eng. Jose Mario Sueiro, who amidst the backdrop of the Second World War, decided to enter the aviation industry. Davins Alfredo Ferrer designed the RR-1 and oversaw its construction that took place in the 4th floor of the factory

IMPA workers not only developed the body of the plane, but the instruments: speedometers, tachometers, compasses, etc. It was noted that there was no way out to the street, a neighbor recalling they even broke one of the walls of the factory to remove.
Sueiro made the maiden flight of July 25, 1942 at the airfield of Pacheco, accompanied by sr. Ciro Comi, which made headlines in major Argentine newspapers. The event was attended by members of the company; national authorities, as the director of Military Industries, Colonel Savio and the director of Civil Aviation, Dr. Samuel Bosch; and the president of the UIA, Luis Colombo.
