The high payload capacity and long flight time, make the HT-100 unmanned helicopter an ideal choice for tactical reconnaissance missions, search & rescue operations, and long-range cargo, transport and logistics deliveries.

Rapid deployment and intuitive operation

Autonomous unmanned helicopterThe complete unmanned aerial system includes a user-friendly ground control station (GCS) with intuitive software, allowing pilots to quickly get to grips with aircraft operation and get airborne as safely and rapidly as possible – in as little as 15 minutes.

Uncompromising safety-first design

The HT-100 unmanned helicopter has been designed with safety foremost in mind and features redundant actuators as well as an electric backup motor. The aircraft is programmed to enter an autorotation mode when the RPM drops below a certain level, allowing for controlled descent and landing in the event of any technical issues.

HT-100 Long-Range tactical uavThe aircraft also features a FLARM collision avoidance transponder, providing enhanced airspace visibility and minimising the risk of collision with other aircraft. The arrangement of lights on the aircraft’s body allows it to be visible at significant distances.

With integrated proven low-vibration technology, the aircraft is capable of long service life. All maintenance cycles up to 1,000 hours can be completed at the customer’s location, while maintenance cycles up to 500 hours can be completed by the customer themselves. Monitoring sensors within the UAV report problems proactively and prevent follow-up costs.
