Foldable drones

Foldable drones have foldable arms, so they fold down from a span of over a foot to the size of a book. That's the main reason they're actually flown: they fit in a backpack and go with you.

The hinged design is a bit more delicate than a solid frame, but it also saves space and the case . It can be set up in seconds without tools.

You can find foldable versions of Xiaomi FIMI camera models and smaller Syma copters. For travel models, check to see if the propellers are also foldable — they make up most of the volume.
