Some of you may remember Buck Rogers and his personal jetpack: the ultimate in personal transportation. Borrowing from the future of helicopter technology, this spaceman makes science fiction a reality. The coaxial contra-rotating lift system provides many advantages over conventional helicopter design. Instead of a tail rotor to overcome the angular momentum effects created by engine torque, the two rotors spin in opposite directions (canceling out the effects) to provided lift. Incredibly easy to fly, our spaceman is recommended for indoor use only. Operates on an internal rechargeable battery charged by conventional AA batteries (not included).
