Detailed Product Features
(1) ESC (Electronic Speed Controller)
45A 4-in-1 ESC: Constructed with advanced electronic components and optimized circuitry, the 45A current rating ensures stable motor operation even under heavy loads. The 4-in-1 integrated design simplifies wiring, reduces the risk of failures, enhances system reliability and stability, while also reducing the overall weight of the drone and optimizing internal space—laying a solid foundation for exceptional flight performance.
(2) Flight Controller
INAV/BETAFLIGHT Dual Systems: Both are industry-leading solutions. INAV is renowned for its precise attitude control and powerful sensor fusion algorithms, enabling stable flight and accurate positioning in complex environments. BETAFLIGHT, on the other hand, excels in fast response and agile handling, supporting various flight modes and custom configurations to cater to both novice and professional pilots. Users can freely switch between systems based on personal preferences and mission requirements.
(3) Receiver
915M Receiver: Operating at the 915MHz frequency band, it delivers stable signal transmission and strong anti-interference capabilities, effectively avoiding frequency conflicts. This ensures that control commands are transmitted to the drone accurately and reliably, enhancing flight safety.
(4) Power Battery
4s/5100mAh Battery: The 4s configuration provides powerful thrust, while the 5100mAh capacity supports a maximum flight time of 30 minutes. Compared to similar models, it significantly extends operational duration, reducing interruptions due to low power and improving efficiency and user experience—especially for long-duration missions.

Customer Inquiry Response Guide
(A) Performance & Configuration
-
Q: Why is this drone equipped with a 45A 4-in-1 ESC instead of a higher current version?
A: This is an optimized choice balancing power needs, weight, and space. While a higher current ESC could theoretically deliver more power, it would add weight and size, potentially compromising flight performance and endurance. This drone is designed to balance high performance and stability, and in real-world use, the 45A ESC performs excellently in high-speed and heavy-load scenarios. -
Q: What’s the difference between INAV and BETAFLIGHT flight controllers? How should I choose?
A: INAV focuses on stable flight and sensor fusion, making it ideal for aerial photography or scenarios requiring high flight precision. BETAFLIGHT offers faster response and customizable controls, preferred by racing enthusiasts. Choose INAV if you prioritize stable flights and camera work; opt for BETAFLIGHT if you enjoy tuning and racing.
(B) Operation & User Experience
-
Q: Is this drone difficult to operate? Can beginners fly it?
A: It is generally beginner-friendly. The 915M receiver provides a clear and intuitive control experience, and both INAV and BETAFLIGHT support beginner modes with assistive features to prevent loss of control. With basic learning and practice—alongside our manuals and tutorials—new users can quickly master it. -
Q: The stated flight time is 30 minutes. Is this realistic in actual use?
A: The 30-minute figure is based on standard test conditions. Actual flight time varies with speed, mode, temperature, wind, etc. Under moderate speed and stable flight, near-30-minute endurance is fully achievable. Even in demanding conditions, its battery life outperforms most similar products.
(C) After-sales & Support
-
Q: What if the drone malfunctions during flight? Is after-sales service convenient?
A: We offer comprehensive after-sales support. If issues arise, contact our customer service team for immediate assistance. Our experienced repair technicians can diagnose and fix problems quickly.
