Question about DJI Mini 3

I have never tested this myself, but other users speak of 50 to 100 g, although I would tend towards 50 g rather than 100.

It is not designed to carry things. But if it helps you. I once attached a Gopro Hero 7 to the bottom. It recognises that something is attached to it and shows this on the display. Flies normally even with the Gopro.
