150:. Thanks to the assistance of the Assistant Secretary of State for Aeronautics (sous-secrétaire d'Etat à l'Aéronautique), a volunteer was found - Lieutenant Georges Férigoule, who was directly in Istra at that time. After the test flight, Ferigul discovered a rather limited lateral control, but admitted that the aircraft had some interesting features. The only drawback was the completely insufficient cooling of the "forced" engine, which developed on takeoff 800 hp. To solve this serious problem, Salmson has installed a new pump to speed up the passage of water in the radiators. But during the flight, thin radiator strips were crushed by a too powerful pump. A tank with cooling engine water, placed in an L-shaped fairing in front of the pilot, depressurized and burned Ferigulu’s face. Fortunately, his eyes were protected by flying glasses ... Forced to land. the pilot refused to prolong the competition, which was won by Sadi Lecuant (Sadi Lecointe) on the Nieuport 29, equipped with a 450-horsepower V-shaped Hispano engine. The Sadi Lekuant airplane covered a distance of 300 kilometers in 57 minutes 50 seconds with an average speed of 31.239 km / h. Thus, the premium of 75,000 francs was issued by Société Nieuport-Astra.

25,000 francs each (the first was intended for the pilot, and the second for the manufacturer of the aircraft, which showed the best speed in both flights) and two annual awards of 75,000 francs. The races in Istra took place on June 23, 1924, on a circular route 50 kilometers long, whose starting point was the center of military aviation (Center d'Aviation militaire).

The SB-3 was based on the SB-2 training aircraft and differed in having a huge nose and rather stocky or pot-bellied outlines. The wing was supported by Y-shaped struts, which rested on the oil-pneumatic shock absorbers of the chassis designed by Louis Béchero (Louis
Bechereau), a patent for which he

According to the Rules of the race were supposed to be international, the cup was played in France during two competitions, each of which consisted of a flight at maximum speed at a distance of 300 kilometers. The winner received a prize of 200,000 francs, which was to be divided into two parts,
