Hi Zhi / @Zhi, and welcome to GADC.
Quite a few members also have the Mavic Air… so you are amongst good company, and a good resource of info if you have any questions. Please feel free to ask away over on #questions-and-answers.
If you haven’t already, take a look at the Map of Members and you’ll get an idea if there are other members in your neck of the wood.
(Don’t forget to add yourself to that map : Members’ Location Map - A Guide)
Also, if you’ve not seen it, check out our map of places where members have flown. Obviously, this is mainly populated by posts from the more sedate drones than yours, but there’s always a change that it might be of assistance.
