The x4-1900h drone has a maximum takeoff weight of 52kg, how is the safety performance guaranteed?

Hello! This drone was designed with safety in mind. Firstly, it adopts the x9 power suite to provide strong power redundancy and maintain flight stability even in the event of partial power failure. Secondly, the dual power system design of hydrogen fuel cell and lithium battery ensures that the flight can still be maintained before the hydrogen is depleted, avoiding the risk of crashing due to lack of power. In addition, it is equipped with an advanced flight control system and a multi-satellite navigation system with automatic take-off, automatic landing, and automatic return, which enables it to automatically take safety measures in the event of an unexpected situation. Meanwhile, we also provide comprehensive safety inspection and maintenance services for the UAV to ensure the safety of each flight.
