It was powered by a
supercharged 9-cylinder
Potez 9B air-cooled
radial engine driving a two-bladed fixed pitch propeller. The engine was specially designed for the competition, which limited displacement to . The primary structure and covering was wood. The first (racing no.10) was flown by
Georges Détré, who won first place, covering the closed-circuit course with an average speed of . The other (racing no.12) was flown by
Gustave Lemoine, who retired after completing the fourth lap. One of the two aircraft entered the previous years was refurbished as the
Potez 532 (or 53-2), to act as a backup in the competition. The engine was uprated, its fuselage was slightly lengthened for aerodynamic reasons, the wing was further enlarged and additional flaps were installed between the fuselage and ailerons. Gustave Lemoine, who was flying the Potez 533 (racing no.3), completed ten circuits with an average speed before being forced to withdraw due to a problem with the variable-pitch propeller. Georges Détré, who was flying the older machine (racing no.1), completed only eight circuits before a broken oil pipe forced him to abandon the race. ==Aircraft on display==
