YouTube - AeroVironment flapping-wing nano-UAV
I do not know how they control everything without a tail. Then again, no rotor means no tail rotor needed for counter-torque like a helicopter; and the UAV is vertical, not horizontal so it does not need a tail to balance out moments applied by the main wing.
