Micro-aerial vehicle is an integrated system that consists of micro machinery

electron and high capability digital computer. It has a bright future in many application fields

especially in military. The paper discusses the characteristics of flight dynamics and the flight control ways of a micro two-rotor rotorcraft. With the help of the power provided by micro continuous current motors driven with lithium cells

the chip microprocessor acting as a control core and the method of remote control and PWM

the micro two-rotor rotorcraft can take off

stay in the sky

fly forward and backward and descend favorably under the condition of breeze. The research has laid a good foundation for further studies of micro aerial vehicles.
