There seem to be quite a few of you who, like me, need to find a replacement Mavic Air controller. It turns out there’s a very easy way to get a new one: get onto the DJI website, go to Product Support, choose Mavic Air, and scroll down to where it says “online support”. That will open up a window with an online representative. Asking, nicely, if you can buy a new controller from them. When I did, he said, “Sure”. It costs $160, and takes somewhere between five and 10 days to get to you. That’s cheaper than many of the used ones you’ll find on the boards, and way cheaper than new ones on Ebay. Problem solved.
