The full PD-100 microcopter, just over 10cm long, would easily fit in a flat pocket-sized case. It will be controlled from a handheld gadget offering video from the camera, simple manual controls, and "route following" using GPS, though this wouldn't work inside buildings. The little aircraft will even offer auto-hovering hands off, with the ability to resist gusts of wind to some degree; and "deployment of special payload" (presumably very small). Flight reports that endurance on a battery charge is expected to be 30min.
The idea is that soldiers might carry a few Black Hornets in a pocket. If they fancied a look inside a building, over a hill or crest, down a tunnel or something, they'd simply launch an almost-silent palmtop microcopter for a recce. Should the tiny chopper come to grief due to flat batteries, a prang or perhaps a rolled-up newspaper, no matter - several cheap replacements could easily be carried. The standard package will come with three aircraft, a pocket controller and a charger.
