Netherlands-based DeltaQuad announced its Evo-LE electric VTOL surveillance drone on Sept. 22, citing up to eight hours of flight and about 298 miles (480 km) of range. Orders are open, but the company has not disclosed a price or delivery timeline.
DeltaQuad attributes the claimed endurance to dual batteries, higher-energy-density battery technology, redesigned electrical architecture and an upgraded VTOL drivetrain. Its Block 3 airframe uses revised composites, with the company citing improved water-ingress protection and dust and rain resistance. Retractable landing gear is designed to keep sensors clear for a 360-degree view.
The stated specifications also include a 13 kg maximum takeoff weight, payload capacity up to 1.5 kg and radio range up to 120 km. Actual performance depends on factors including wind, altitude, flight profile and payload; DeltaQuad has not published payload-specific endurance or independent benchmark data. Anti-jamming equipment, secure communications and autonomous navigation are configurable options, not standard on every unit.
