PicooZ

From UfoWiki

According to the Guinness Book of World Records, the PicooZ is the smallest commercial remote controlled helicopter, weighing only 10 grammes. Controlled by a 2 channel (throttle and yaw) infra red transmitter, it has to be balanced to fly forwards by itself. It is intended for indoor use only, as bright daylight will interfere with the IR signals and wind will make it incontrollable. Its 45 mAh Lithium Polymer ("LiPo") flight battery allows for around 8-10 minutes of flight time, while its soft EPP body and little weight make it very inured to crashes.
