Super superior to other insects (RC and not), the Mantis employs both electronic and mechanical gyroscopic stabilization for rock-steady hovering. The tail-rotor is also controlled by a micro motor for true yaw-axis stability. Move forward, turn left, and turn right – this bug can fly anywhere indoors.
Power is supplied by an on-board Lithium Polymer battery pack, which is charged via a quick charger built into the Mantis two-stick transmitter.
The MegaStealth Mantis 2-Channel Electric R/C Insect is currently available for $49.95 over at the Edmund Scientific website. (Update: Link removed because the page is gone.)
