Fly another day: The James Bond inspired 'microcopter' that will come in packs of three
The world's tiniest helicopter has been specially developed for spies and soldiers
Weighing in at just 0.5g, the tiny servos mean the PD-100 is even smaller than a toy battery helicopter.
Powered by an electric motor, the microcopter has 4in rotor blades, carries a tiny digital camera and flies at speeds of up to 20mph.
It has been tested successfully inside and outside in very light winds.
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.
