4. Pre-Sales Q&A

Q: What advantages does a hydrogen fuel cell offer over traditional lithium batteries?
A: Hydrogen cells have much higher energy density, enabling 2-hour flights while maintaining similar weight. They can be refueled in minutes—far quicker than recharging batteries. Plus, they produce zero emissions during operation, aligning with green energy trends.

Q: How is centimeter-level positioning achieved?
A: We use RTK via real-time differential correction and multi-GNSS (GPS/Galileo/BeiDou), boosting positional accuracy to centimeters. This enables rigid adherence to flight paths, essential for tasks like inspections or precision spraying.

Q: Is this drone difficult to operate? Is professional training needed?
A: The drone is user-friendly with auto-takeoff, auto-landing, and return-to-home features. While training helps optimize mission deployment in industrial settings, even non-experts can begin flying safely with provided tutorials and manuals.

Q: Can you achieve 20 km video transmission in real scenarios?
A: That distance is possible under ideal, unobstructed conditions. Obstacles like buildings and terrain may reduce range, but the VW20 system has strong anti-interference capabilities. Even at shorter ranges, you will still receive reliable video and telemetry.

Q: What is the lifespan and replacement cost for the hydrogen tank and fuel cell?
A: Hydrogen cells typically last hundreds to over a thousand operational hours with proper maintenance. Replacement costs are moderate and tailored to client needs—please contact our after-sales team for quotes
