The H.V.41 and H.V.40 were two designs ordered for use by the French team in the 1929 Schneider Trophy. Although the H.V.40 was to be powered by a radial engine, the H.V.41 was to use a new liquid-cooled Hispano-Suiza 12Ns Special. It was a streamlined single-seat cantilever monoplane and had two metal floats attached underneath the fuselage on inverted vee-struts. The H.V.41 was ready for testing by July 1929 but due to delays with the engine it did not fly until August and the French government withdrew the team from the 1929 race. The aircraft was then used for training by the French Schneider Trophy team.
