With the rapid growth of high-rise and super high-rise buildings in modern cities, firefighting UAVs are emerging as a crucial solution for high-rise rescue operations, offering heavy payload capacity, rapid deployment, and extended endurance.

400kg Payload. 200m Tethered Altitude. Up to 12 hours of Continuous Operation. These capabilities are expanding the possibilities of firefighting drone powered by high-voltage propulsion systems, addressing the growing demand for greater reach, heavier payloads, and longer operational endurance in high-rise firefighting scenarios.

The XF12-400 Tethered Firefighting UAV developed by Yunding Technology is powered by the HOBBYWING P115M 800V Coaxial Drone Integrated Propulsion System. Combined with a tethered high-voltage power supply solution and rapid vehicle-based deployment, the platform enables efficient firefighting operations for buildings up to approximately 67 stories.

Leveraging the high thrust and efficiency of P115M drone power system, the XF12-400 heavy-duty drone can reliably carry firefighting hoses, water cannons, and compressed air foam systems (CAFS), enabling long-range water and foam suppression for high-rise firefighting. With a two-person operation team, this supports rapid deployment, precise control, and improved emergency response efficiency.

Beyond firefighting, the XF12-400 industrial UAV can be equipped with a wide range of mission payloads, including EO cameras, thermal imaging cameras, drone lighting systems, and emergency supplies. The P115M 800V enables tethered firefighting UAVs to support extended-duration operations across diverse emergency scenarios with reliable propulsion performance.

With continued advancements in high-voltage propulsion technology, HOBBYWING P115M is driving the next generation of firefighting UAVs with enhanced performance, greater reliability, and expanded mission capabilities.
