This innovative R/C helicopter from Japantrendshop is basically controlled by “speaking into the controller [up / down] — physical controls are included for steering and forward/backward motion.” Video after the break.

The helicopter uses a stacked-rotor design to avoid the need for a rear propeller, as well as a very cool ceiling sensor that detects obstacles above and automatically stops the helicopter’s ascent.
