In essence a floatplane variant of the HM.1, that vicious handling primary trainer. The two HM.3’s built were tested at the end of the 1940s. Certain problems soon appeared, mainly questionable float design and lack of power. The Spanish AF didn’t show any further interest in them and that was the end of it.
The “HM” acronym stood for its designed: Huarte Mendicoa, but jokingly, some said that it came for “Hombre Muerto”……,”Dead Man” in Spanish.
