Superior Endurance in Critical Unmanned Aerial Applications

SDO 50 V2


Heavy Lift High Performance Unmanned Helicopter

The SDO 50 V2 is a multi purpose, unmanned helicopter system, that can be operated within or beyond visual line of sight. The unique design features of the SDO 50 V2 provide a superior payload capacity, long endurance, stable flight patterns and a high degree of safety features. An integrated autopilot system allows autonomous take-off and landing procedures as well as automated flight patterns. The SDO 50 V2 uses the powerful construction principle of intermeshing rotors (going back to Anton Flettner). It functions through a set of two rotors turning in opposite directions with each rotor mast mounted with a slight angle to the other so that the blades intermesh without colliding. The arrangement also allows the helicopter to function without a tail rotor, which saves additional power. As a result, the SDO 50 V2 currently is the only flying UAV in the market which is being capable to lift more payload than its own empty weight.

Key Features

High Endurance

Endurance of up to 3 hours, depending on configuration.

Long Range

Standard radio-line-of-sight range of up to 50 Km.

Auto Missions

Smart automated flight missions, specific payload control, automatic return to launch fail-safes and various other features are available for peace-of-mind operations.

Multiple Payloads

Designed to easily integrate different payloads weighing up to 45 Kg (95 Pounds), ranging from high-resolution mapping systems, advanced surveillance cameras with object tracking, LiDAR, nanoSAR, and more.

Rapid Deployment

Rapid logistics, up to 2 personnel, van or pick-up, setup in 15 minutes.

Born to be diverse

We offer a selected range of high-end sensors
already integrated with the SDO 50 V2. Additional
payloads can be integrated upon request.



The deployment of UAVs for Intelligence, Surveillance and Reconnaissance (ISR) missions has been part of civil and military operations for some time. Systems applied aim for long-range surveillance, intelligence gathering and tactical combat operations, typically carrying MWIR, incl. EO/IR (electro optical and infrared) and LRF sensors.



Near-earth spectroscopy from UAV-hyperspectral sensor systems addresses the limitations of resolution, cloud cover, and signal-to-noise ratio from traditional airborne or satellite platforms.


Aerial Laser Methane Assessment

Providing operational diagnostics of extended gas transmission and gas distribution facilities for leaks. The system is also used for exploration of gas fields.



Light detection and ranging (LiDAR) sensors use light energy, originating from a laser, to scan the ground and variable distances. The outcome is a rich set of elevation data that can be used to produce high-resolution maps and 3D models of natural and man-made objects.
