Why Choose KEEL PRO ?

Unmatched Heavy-Lift Performance with Extreme Stability

Engineered to transport payloads up to 70kg, this drone delivers a remarkable 25-minute flight time at full capacity. Its innovative coaxial eight-propeller design and a max takeoff weight of 140kg ensure powerful, stable, and safe flight even in challenging conditions (18m/s wind resistance), redefining reliability for critical missions.

Modular & Rapid-Deployment Design for Ultimate Operational Agility

Featuring a quick-release carbon fiber frame and interchangeable arms, the system can be assembled or reconfigured by 1-2 persons in minutes. This modularity, combined with a compact three-proof aviation case, transforms it from a transport-ready package to an air-ready workhorse with unprecedented speed and flexibility in the field.

Advanced, Customizable Power & Integration Ecosystem

Equipped with a high-energy dual battery system (18S 84Ah) for extended endurance and a self-developed, aviation-grade PDB supporting 36-120V input, it ensures robust and stable power for diverse payloads. Strategic partnerships with leading propulsion manufacturers provide exclusive, calibrated power system adaptations (A12XL, H11M, X11 Max) for tailored performance.

Professionally Engineered for Durability & Mission Scalability

Constructed with forged high-strength carbon fiber (30% stronger) and featuring integrated shock-resistant electronics, the drone is built for durability. Multiple standardized interfaces and support for various transportation modes (hoisting, storage, winch delivery) allow for seamless adaptation and scalability to meet specific industrial, logistics, and special operation requirements.

Super-strong Carrying Capacity And stable Flight

After thousands of flight verifications and professional data adjustments, it can still fly safely and stably under extremely heavy loads.

High-Capacity Payload & Stable, Maneuverable Flight

The Keel Pro Drone delivers robust payload capacity and reliable flight performance—validated through thousands of flight calibrations and professional data tuning to ensure safety and stability under heavy loads—while boasting maneuvering specs of 100°/s maximum rotation rate and 25° maximum pitch angle.

Ultimate Modular Mobility: Transport Redefined

Quick-Deploy Frame, Interchangeable Arms & Compact Aviation Case for Unmatched Operational Agility

Diversified Transportation Modes

It supports various transportation methods such as hoisting, storage, and throwing, and has Highly modular design and task scalability enable the provision of customized adaptation services based on user needs.
