Quadcopters

Hello)Quadcopter for a traveler - what should be his characteristics?
I think these are:

  • had suitable dimensions (possibility to put in a backpack)
  • weight (of course the less the better)
  • FPV (the ability to see what you are shooting)
  • HD camera. https://www.bestadvisor.com/quadcopters
    Or maybe you have something else?
