Hello, where i can buy more magnetic mount for the action 3 and also the remote controller? i can't find anything on the Dji website

I also checked on Amazon and Aliexpress but nothing yet available.

Thanks in advance

The only way I've seen so far to get more of the little quick release mounts is with the "adhesive mount."  Here is a link for one.

As for a remote controller, there is nothing official for the Action 3 that I'm aware of.  Some have said this one works.

Also, both of those are available on DJI's online store as well.  Probably Amazon too, but they may be harder to find among all the junk that comes up on Amazon these days.

As for the remote controller, there's no remote controller for DJI Action 3 yet. Some users said that DJI Action 2 remote controller works with it but we can't guarantee that yet. You may check this thread for more information: https://forum.dji.com/forum.php? ... D781%26typeid%3D781

Thank you for your valued support. Have a good one!

DJI Action 2 remote controller works great with my DJI Action 3
