The Y-726 multi-rotor drone features a body made of high-strength composite materials, which is lightweight, sturdy, wind-resistant and rain-proof, to make it suitable for long-term outdoor operations. The advanced flight control system enables centimeter-level hovering and autonomous route planning, and supports multiple safety strategies such as one-click return and low-battery return, and lowers the operational threshold. The high-definition pan-tilt camera is combined with three-axis mechanical stabilization. It can output stable and smooth images day and night, and provide precise visual support for industries such as inspection, mapping, and search and rescue. The modular battery and quick-release structure make maintenance simpler and significantly reduce the operation preparation time. The open mounting interface can flexibly carry various task devices such as loudspeakers, searchlights, and gas detectors, meeting the needs of diverse scenarios.
