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.

Is the hydrogen refueling process complicated for hydrogen fuel cells? Are hydrogen refueling stations convenient?

Hello! The hydrogen refueling process of hydrogen fuel cell is not complicated, we provide users with professional hydrogen refueling equipment and detailed hydrogen refueling operation guide. The hydrogen refueling process takes only a few minutes to complete, and the operation is simple and fast. As for hydrogen refueling stations, although the number of hydrogen refueling stations for hydrogen fuel cells is relatively small at present, with the development of hydrogen energy technology, the number of hydrogen refueling stations is gradually increasing. In addition, we are actively cooperating with relevant organizations to promote the construction of hydrogen refueling stations to provide users with more convenient hydrogen refueling services.

Is the 20km mapping distance achievable in practice?

The 20km mapping distance is tested under ideal conditions of no obstruction and no interference. In actual use, the transmission distance will be affected by terrain, building obstruction and electromagnetic interference. However, our mapping system adopts advanced anti-interference technology, which can reduce the influence of these factors to a certain extent. As long as it is used in an open area and avoids excessive obstruction and interference, it is usually possible to achieve a longer transmission distance. Moreover, even when the mapping distance is limited, you can still obtain the UAV’s flight status and part of the operation data through the real-time data transmission function of the ground station to ensure the smooth operation.

Will the 52-minute range be enough for real-world operations?

Hello! 52 minutes of endurance (unloaded) is already a long endurance among industrial-grade drones. For most of the application scenarios such as mapping, inspection, etc., this endurance can already meet the needs of a single operation. If a longer operation is required, it can be achieved by replacing the battery or optimizing the flight path. In addition, the large-capacity battery design also reduces frequent battery replacement or charging time due to insufficient power, which improves operational efficiency.

What are the advantages of hydrogen fuel cells over conventional lithium batteries?

Hello! The advantages of hydrogen fuel cells are mainly reflected in the following aspects: firstly, the energy density of hydrogen fuel cells is much higher than that of traditional lithium batteries, which means that in the same volume and weight, hydrogen fuel cells can provide longer endurance, and the unloaded endurance of our drone can reach up to 2 hours, which is a significant improvement compared to traditional lithium battery drones. Secondly, hydrogen fuel cell hydrogen refueling process is very fast, only a few minutes can be completed, while lithium battery charging usually takes a longer time, which greatly improves the efficiency of the drone, especially suitable for long time, continuous operation scenarios. In addition, hydrogen fuel cells produce almost no pollutants during use, which is more environmentally friendly and in line with the trend of future energy development.

What additional support or services come with this drone after purchase?

Upon purchase, you’ll receive a complete set of support services, including detailed user manuals, step-by-step operation guides, and online technical assistance. We aim to help you get familiar with your drone quickly. If you encounter any technical issues during use, our support team is always ready to assist—ensuring a smooth and efficient user experience.

What’s the difference between INAV and BETAFLIGHT flight controllers, and how should I choose?

INAV is known for its precise attitude control and advanced sensor fusion, making it ideal for tasks like aerial photography and stable hovering. BETAFLIGHT, on the other hand, is designed for fast response and extensive customization, catering to users who prefer agile handling or enjoy tuning their systems. If you prioritize flight stability and camera performance, go with INAV. If you’re into racing or want full control over tuning, BETAFLIGHT is the better option.

The drone’s endurance is 30 minutes, so can it actually fly for that long?

Hello! The 30-minute range is derived under standard test conditions, and the actual flight time will be affected by a variety of factors, such as flight speed, flight mode, ambient temperature, wind and so on. Under normal flight speed and stable flight mode, an endurance of nearly 30 minutes is fully achievable. If flying at higher speeds or operating frequently in complex environments, the endurance time may be slightly shortened. However, compared with similar products, our drone does have a clear advantage in endurance and can meet the long time operation needs of most users.
