1 / 5
It achieves a max horizontal speed of 30 m/s and withstands winds up to 12 m/s, delivering reliability and efficiency in diverse environments.
With a maximum flight time of 120–180 minutes and a 10 kg payload capacity, KEEL ensures stable, long-range operations for demanding missions.
Engineered with upper/lower expansion interfaces and Pandora quick-release, KEEL adapts seamlessly to logistics, inspection, and emergency response tasks on a unified platform.
Featuring quick-release carbon fiber arms and interchangeable components, the drone allows single-operator assembly in 60 seconds and flexible payload integration.
The keel's advanced lightweight construction ensures exceptional ease of transportation and rapid deployment, without compromising structural integrity or payload capacity.
KEEL provides two upper expansion interfaces (*commonly used for GPS and secondary development) and two wire-through holes (*commonly used for RTK installation and upper and lower mount positions). It is equipped with one Pandora quick-release interface and a data transmission interface at the bottom. Under the condition of sufficient space, it can carry seven devices simultaneously.
This graph demonstrates KEEL's high power efficiency of up to 25 g/W at lower thrust levels, with performance data systematically measured across the full throttle range, providing transparent and reliable benchmarks for operational planning.
