It's the Moz7 from GepRc (https://geprc.com/product/geprc-moz7-hd-o3-long-range-fpv/). The price of this drone alone is around 700 USD, but you also need a radio, FPV goggles, batteries and a charger. It's easier to start with something like the DJI Avata II where you have all needed components in a set. However, DJI drones have some annoying limitations.
