Hydra Technologies Ehecatl is a Mexican fixed-wing military/ISR drone built for endurance-focused observation rather than consumer flying. In the supplied public data, it stands out for a **55 kg maximum takeoff weight, 8-hour endurance, 167 km/h top speed, and a 4,572 m ceiling**. That makes it relevant to defense analysts, institutional buyers, and readers comparing tactical fixed-wing UAVs with more serious mission potential than typical multirotors.
