Skyfront Perimeter 8 ready-to-fly with ground control station.

THE EASIEST, SAFEST AND LONGEST ENDURANCE HYBRID MULTIROTOR ON THE MARKET

The Perimeter 8 UAV features an impressive 12 lb. / 5.5 kg payload capacity with 1 hour of endurance and a no-payload endurance of over 5 hours. The Perimeter 8 is just as easy to operate as the Perimeter 4, but has full propeller, motor, and ESC redundancy. This redundancy in addition to electronic fuel injection and a 5 minute battery backup reserve flight time ensures the safety of high-value payloads.
