As we reported before, a new drone called DJI Mavic Air will be announced on January 23rd, 2018 in NYC. DJI USA official website now already leaked url of DJI Mavic Air official web page. You can now simply visit WWW.DJI.COM/Mavic-Air. It redirects you to the official DJI.com homepage. Unlikely other upcoming DJI drones url: Mavic 2 (dji.com/mavic-2) or Phantom 5 (dji.com/phantom-5), you get a redirect to 404 pages.
Also mobile page of DJI Mavic Air also redirect to homepage: www.dji.com/mobile/mavic-air.
