Confused about getting into FPV drone hobby.

I have been super interested in the flywoo explorer lr. As I look into purchasing it online, I run into more questions than anything. The receiver, batteries, radio, I DONT EVEN KNOW! Basically, to get into the FPV hobby, or to get myself an explorer lr, it's not merely about buying the drone, is it? I'll have to buy a bunch of other stuff to actually fly it and video? Correct?, via /r/drones https://ift.tt/367cjUZ
