◆ FAQ

How to maintain a drone?
Maintaining a drone requires regular inspection and care. First, make sure the battery stays charged and avoid overcharging or discharging. Clean the fuselage, propellers, and camera regularly to remove dust and debris. Check the propellers for cracks or damage and replace them in time. Calibrate the gyroscope and GPS before flight to ensure stability. After flight, check the battery, motor, and control system to confirm that there are no abnormalities. Update the firmware regularly to ensure the latest performance of the device. In addition, avoid flying in adverse weather conditions to extend the life of the drone.

What is the safe operation guide for Drone?
First, make sure you are familiar with local laws and regulations before flying, and avoid flying in no-fly zones. Maintain line of sight during flight to avoid loss of control or signal. Check the status of components such as batteries, motors, propellers, etc. to ensure that the equipment is in good condition. Avoid strong winds, heavy rain or thunderstorms during flight to ensure stable flight. Comply with flight altitude restrictions to avoid collisions with buildings or people. Calibrate GPS and gyroscopes regularly to ensure accurate navigation. Finally, shut down the drone in time and store it properly after the flight.

How to extend the life of drone batteries?
The key to extending the life of drone batteries is to avoid overcharging and over-discharging. Before each charge, make sure the battery is between 20%-80% and do not wait until the battery is completely exhausted. Use the original charger and avoid using non-compliant charging equipment. Avoid flying in extreme temperatures, especially in overheated or cold environments, as high temperatures will accelerate battery aging. Use the battery regularly and avoid leaving it for too long when not in use. Charge it promptly after the flight to avoid the battery being in a low power state for a long time.
