SDO 50 V2 Helicopter UAV

Long-range autonomous helicopter drone for inspections, surveillance, search & rescue, and monitoring

The SDO 50 V2 is a state-of-the-art unmanned helicopter with a flight endurance of over 3 hours and the ability to operate day or night in adverse weather conditions, such as rain, snow and wind speeds of up to 21 knots.

UAV helicopter

Based around a proprietary Flettner intermeshing double rotor design, the SDO 50 V2 offers enhanced payload capacity and flight stability.

swiss drones UAV helicopterThe VTOL (vertical take-off and landing) system is highly cost-effective compared to manned aerial solutions, and requires less training to operate confidently. The rapidly deployable aircraft is transportable by van and can be prepared for flight by a team of two in just 15 minutes.

The SDO 50 V2 UAV is equipped with an advanced autopilot and high-performance GPS receiver and magnetometer, with optional redundant systems. The aircraft’s datalink consists of a primary S-band link and a secondary UHF-band link, with additional LTE/4G capabilities available upon request.

The helicopter UAV is controlled via a rugged portable GCS (ground control station), which features a built-in keyboard, monitor, and 3-axis joysticks.

Versatile UAV for multiple (exchangeable) payloads

With its superior carrying capacity, the SDO 50 V2 can carry multiple sensors and payloads for versatile long-range mission capabilities and large flight autonomy. We offer a range of leading sensor solutions as standard.
