Description This folding remote control quadcopter features APP mobile phone control, back with one key, headless mode, ascending and descending, forward and backward, left and right side flight, hand gesture photography, optical flow positioning, brushless motor, ultra-long endurance, low battery alarm, obstacle avoidance head assembly, 2.4GHz anti-interference technology, six-axis gyroscope, customize the route, and so on. Features: The front lens is placed with wide-angle 4K high-definition WIFI, the bottom high-definition lens with the optical flow can switch the camera angle, the servo pan tilt is designed to increase stability, and the EIS electronic anti shake is added to make the photo line clearer. The height fixing function has the height keeping mode function, and the optical flow positioning and fixed-point function have a stable flight. With the obstacle avoidance head assembly, the drone can stop when encountering obstacles without colliding with them. If the distance is exceeded, the UAV will not be lost. It only needs to be connected to the front signal to control the UAV again. The size and weight of the drone are light, and the body weight is 145g, which can circumvent national aviation control (some countries require certification or registration for UAVs over 250g, and 210g can eliminate the challenge of certification and registration).
