What smoggy hellscape city is this filmed over? I've never seen such a dark dreadful and polluted skyline in my life. I don't know how anyone could live with that air quality!

Completely VLOS - Does China not have any restrictions on drone flights?

[@PowerheadProductions]

What transmitter/drone was this with? Do you have anything showing the improvements of your amplified signal booster for the Cendence controller vs. the standard DJI panel antenna?
