-History

The birth of the SV4 goes back to 1937 when Elsa Leysen, one of Jean Stampe flying school trainee pilot, contact the latter : She wishes a light aerobatics aircraft higher to Tiger Moth and Bücker Jungmann. In 1933, Stampe and Vertongen had built the S-IV (become SV4 thereafter). The aircraft consisted of a top positive sweeptback wing staggered to the front and a bottom wing, straight, equipped with ailerons. The prototype took-off from Deurne in 1933. On the basis of the SV4, ingineer Demidoff draw a new aircraft characterized by a shorter fuselage, a new empennage and a reduced wingspan. The wingframe, with meaner wing section, was equipped with wing tips, the two wings equipped with ailerons, despite their dissymmetry. The prototype called SV4-B, flew on september 1937, equipped with the Gipsy Major I inverted engine of 130 ch. Winner of the contest for basic training aircraft for the Belgian Army, it was finally delivered to its owner, Elsa Leysen, with whom it took part in many meetings and appeared definitely higher than Tiger Moth and Jungmann. Still wishing to perfect this plane, Stampe built a second and third SV4-B in particular improved by the adoption of symmetrical wings with positive back sweep. This new SV4-B was presented in France in 1939 and there cause sensation. France then placed an order for 600 aircrafts whose construction was to be ensured by the Farman company which acquired of the licence. Because of the war, only 20 SV4-B were completed in Deurne. 11 aircrafts were then in the course of assembly in the Farman factory in Turenne. The shortly after the hostilities, French authorities choose the SV4 to start again the Armée de l'Air flying schools. Equipped with the Renault 4Pei engine of 140 ch, then available, the 1st SV4-C took the air in January 1946. The Ministère de l'Air ordered 700 aircrafts. The Stampe saga in France had just started.
During its career the aircraft will be equipped with various engines since Renault 4P, 4P-03, 4P-05 for aerobatics(SV4-A), 4P-106 injection engine, to Mathis 7 cylinder radial engine of 175 ch , which equipped the SV4-D prototype of Patrouille d'Etampes.
