I don't have any drone ..so should i not able to review ..for making review do we have to have drone ..let me know
Yeah, you need to own a drone on the site and prove it by submitting a photo you took of it with a piece of paper with today's date written on it.
Quadcopters don't write Drone!
Not all drones are quadcopters (for instance the TBS Gemini is a hexacopter). Anyways, who cares? I think everyone here is smart enough to realize that we're reviewing personal/commercial unmanned aerial vehicles, not military killing machines that bring mostly automated death from the sky.
