It represents the pinnacle of a power platform optimized for ultra-heavy, long-endurance, and high-power-density missions. If the 4114 is a “performance monster”, then the 4215 is an “industrial behemoth” born for large-scale, commercial-grade heavy-duty operations. It is specifically designed to drive the largest commercial logistics drones, heavy-duty mapping platforms, and special operation drones. Its core advantages lie in:
On the super-large platform, the best balance among payload, flight time and reliability has been achieved. Through the ultimate “large propeller low revolution” efficiency, it provides operators with the lowest transportation cost per kilometer. Its industrial-grade design and manufacturing standards ensure that large-scale fleets can operate stably and efficiently on a continuous basis.
