From February 26 to 28, 2025, the Busan International Exhibition and Convention Center in South Korea held the three-day annual Asian drone event – Drone Show Korea 2025. This exhibition attracted 306 companies from 15 countries and regions around the world, focusing on displaying cutting-edge technologies and innovative applications in the industry, setting a historical record.
At this exhibition,ZHT Aero showcased the 46950 high energy density batteries for drones, bringing a new drone energy solution with breakthrough technological innovation. The 370Wh/kg series has been successfully tested on the KEEL Pro transport drone, with an endurance improvement of nearly 60% compared to the past, and a cruising flight of up to 55 minutes with a 30kg payload, meeting the long-duration and long-distance operation requirements of logistics distribution.
This time, ZHT Aero also sincerely brought three self-developed drone frames – KEEL, KEEL Mini, and KEEL Plus. Since its launch, the KEEL modular quadcopter has won praise from many customers for its excellent performance. It adopts an H-shaped structure and has a superior aerodynamic layout. It is more stable during flight and can reach a maximum speed of 30m/s. It performs well in terms of load and endurance. It can last for 160 minutes without payload, which is the time for a big movie. It can fly continuously for 30 minutes when fully payloaded with 10 km. This year, we will continue to optimize its performance to make the payload and endurance more durable.
KEEL Mini and KEEL Plus were born to meet the needs of customers. The maximum payload of the KEEL Mini standard version is 10kg. We have optimized the symmetrical wheelbase to 906mm, making it compact and small. The fastest instantaneous speed can reach 40m/s, comparable to a large-sized FPV drone. KEEL Mini can also support 22-24-30-inch propeller adaptation through the change of expansion modules, and is compatible with a variety of motors. It has strong DIY properties and can meet the personalized modification needs of users.
KEEL Plus supports dual power systems, and PID has been adapted to Hobbywing and T-MOTOR power systems, so users can fly right away. Continuing KEEL’s superior performance, the maximum payload can reach 30kg, the effective flight time is 25 minutes, the wheelbase is 1375mm, and it can be deployed by one person.
The KEEL series of drones are multi-functional and can provide customers with a full range of flight platform solutions. It is the best choice for users in different application scenarios.
During the exhibition, 中航通创新（天津）科技发展有限公司 reached a number of cooperation intentions with customers in South Korea and Southeast Asia, involving logistics distribution, offshore fishing, environmental research, emergency rescue and other application scenarios. In the future, our company will combine South Korea’s geographical environment and industrial needs, deepen local deployment, further consolidate its brand influence in the Asia-Pacific market, and inject new momentum into the global development of the low-altitude economy.
