Questions about Lowepro DroneGuard BP 250 Black

The bag is modular, so in my humble opinion there's plenty of room for the Mavic 3, which isn't much bigger than the Mavic 2.

the inside is divided by a soft fabric dividers with velcro straps on their sides. You can change it in any way you like. There is a small soft fabric cuboid which helps to keep remote controller in place.

Yes, of course! The bag is big enough to carry a drone with its many accessories (e.g. extra batteries, etc.) as well as a camera or video camera. I have a Mavic 2 Pro in the bag, a lot of accessories and a SONY 4K camera with two batteries. Everything fits without any problem.
