The H.Vb enjoyed a successful career but was eventually abandoned to the elements when the brothers had pressing wartime commitments. This aircraft was rebuilt as the H.Vc, flying in 1942. Eventually the H.Vc succumbed to a crash in 1943 after the pilot attempted a take-off with full landing flap selected, hit a hangar and dropped to the ground.
