Perimeter 4 Quadcopter Drone

Long-range gas-electric quadcopter drone

Perimeter 4 Quadcopter Hybrid Gas Electric Drone

The Perimeter 4 is a gas-electric hybrid quadcopter built to surpass the flight time and range limitations of traditional drone mapping and surveying missions. Featuring a unique proprietary hybrid gasoline-electric propulsion system with electronic fuel injection and backup battery, the long-range quadcopter can achieve a maximum flight time of over five hours and a distance of 110 miles.

Gas electric endurance quadcopter droneThe Perimeter 4 can carry a wide variety of payloads of up to 8.8 lb (4 kg), making it a versatile platform capable of undertaking long-range, long-endurance missions for mapping, inspection, surveillance, military ISR (intelligence, surveillance and reconnaissance) and more.

Selected compatible state-of-the-art sensor payloads include:

  • Sony visual image and video cameras
  • SLANTRANGE and Micasense RedEdge precision agriculture multispectral sensors
  • Routescene and Phoenix LIDAR mapping systems
  • FLIR visual & thermal imaging sensors
  • Geometrics Magarrow magnetometry sensors.

With custom engine control and Pixhawk-based autopilot electronics, the Perimeter 4 features automatic takeoff and landing, autonomous waypoint navigation and specialised survey flight modes.
