Perimeter 8

Mission capable drones

The easiest, safest and longest endurance hybrid drone.

The Skyfront Perimeter 8 and 8+ hybrid drones can carry up to 10 kg (22 lb.) for up to one hour and 5 kg (11 lb.) for 2-3 hours. The combination of heavy-lift and high-endurance reduces field time from days to hours.

Usability.

Built for ease of use, assembly and transport.

Engine autostart

Engine is automatically started and stopped. No pull starts or cumbersome drill starter motors.

Quick deployment

The Perimeter can be unboxed, assembled and flown in less than 5 minutes.

Modular payload bay

Accommodate payloads more than 11 lb. (5 kg) with form factors ranging from LiDAR units, visual and thermal cameras and more.

Engine integration

Engine operation is fully automated, from start to finish. Just refuel and fly like a regular multirotor.

Full engine telemetry

Engine health information is made available on the ground station. The engine can be started and stopped through the ground station.

Extremely lightweight

The Perimeter is 20% lighter than any hybrid-electric multirotor on the market today.

Airline Transportable

The UAS is small enough to be transported on an airliner, saving tens of thousands on shipping costs.

Digital fuel level indicator

Fuel levels are visible on the ground station.

FAQ

Product

How does the Perimeter 8 get such long flight times?
The Perimeter 8 is powered by an internal combustion two stroke engine that spins a generator. The high energy density of gasoline and the weight and efficiency of the Perimeter 8 design lead to long flight times.
Is the Perimeter 8 powered by gasoline/petrol?
Yes, there is a two stroke internal combustion engine which supplies power to the drone’s electric motors.
What is a hybrid drone?
A hybrid drone is a multirotor drone that is powered by a hybrid-electric power source. This hybrid-electric power source converts gasoline/petrol into electricity, which is then distributed to the propellers in motors. The drone can fly for much longer than a battery powered drone because gasoline has a much higher energy density than that of batteries.
How much does the Perimeter 8 cost?
Prices start at $46,800
