Mine just arrived from Adorama.
Was surprised to see the case be actually bigger than my
Mavic 2 Pro FMC shoulder bag. When I travel, I put the drone and the 3 batteries into that bag along with extra propellers and some other accessories. The bag takes up about 1/3 of my carry on suitcase.
The Air 3S case has a bigger footprint than the
Mavic 2 Pro shoulder bag though it's not as thick. But the reason is that the Air 3S case is built to carry the battery charging hub as well as the controller.
So I think I would keep using the
Mavic 2 Pro FMC shoulder bag for the Air3S. The batteries though, I can only fit 2 of the Air 3S batteries because they're longer and thinner whereas the
M2P batteries were wider and shorter so I could stack 3 of them in one half of the
M2P bag.
I also realized the Air3S has a slightly bigger footprint than the
M2P when the legs ar folded. The reason is, the gimbal juts out from the body and that gimbal cover protrudes away from the aircraft body as a result.
So it's about an inch to inch and a half longer than the folded
M2P. I can probably still fit it in the
M2P bag but it probably makes the cover of the bag put more pressure on that gimbal cover. I have to be careful that when I pack my carryon, it won't press against the bag or else it might crack that gimbal cover if there's enough pressure on it.
Not likely but it's possible.
The other thing I noticed, the RC-N3 is going to require getting used to. When I slide my iPhone 16 Pro Max, I have to be careful because the bracket which holds the phone is pushing up against the button. In particular the camera action button of the iPhone which is on the right lower half. So I have to set the iPhone a little more left of center or right of center to avoid it activating the iPhone Camera app.
