Bought on Ali for the money of the gods. I went back to the same retailer and placed an order for three more batteries as well as a set of four AA batteries for the remote control right away. In addition, we have spare propellers and a set of antennas that may be used to extend our range. It is usually beneficial to have a sufficient supply of screws on hand. To our great relief, they are inexpensive. If you abruptly disappeared from sight, be sure that the remote control is not turned off. Take a picture of the display, and then search for the flying gadget using the coordinates that are displayed on the display.
