About the Quaternium HYBRiX.20

The Quaternium HYBRiX.20 is a Spanish-designed hybrid-electric unmanned aerial vehicle that holds the world record for longest multirotor flight endurance — over 10 hours aloft on a single tank. Built by Quaternium Technologies in Valencia, the HYBRiX combines battery power for vertical takeoff and landing with a small gasoline generator that recharges the batteries in flight, enabling mission durations that pure-electric drones cannot match. The quadcopter configuration provides stability and redundancy, while the 25-kilogram maximum takeoff weight keeps it in the small UAS category for most regulatory frameworks.

Certified under EASA's Light UAS Operator Certificate standards, the HYBRiX.20 serves commercial operators conducting long-range inspection, mapping, and surveillance missions where traditional battery-only drones would require multiple battery swaps or simply cannot reach. Its hybrid propulsion architecture represents a pragmatic middle ground in the ongoing electrification of aviation — trading the simplicity of pure battery power for the extended range that liquid fuel energy density still provides. The type operates primarily in Europe and Latin America, where infrastructure inspection and precision agriculture demand both VTOL convenience and multi-hour loiter capability.
