Using the GEPRC Vapor D5 HD O4 Pro FPV Drone is easy. First, make sure you have a recommended 6S LiPo 1300mAh - 1800mAh battery. Connect the battery using the XT60 connector. You can choose your preferred receiver from the options like PNP/GEPRC ELRS24/TBS Nano RX. Before taking off, double - check all the parts are properly assembled. When flying, the drone's features like the front lip design will protect the lens, and the wide carbon fiber arms give it good durability. After the flight, it's important to maintain your drone. Remove the battery and store it properly. Check the motors, propellers, and other parts for any signs of damage. If you notice any issues, replace the parts as needed. The included spare screw pack can be very handy for small repairs. Also, clean the lens regularly to keep the image quality high. And don't forget, you can use the GoPro mount for some cool video - taking.
