Abstract:
An ultrasonic remote airplane for playing an air-battle game, comprising:a rudder and a propeller; a main remote circuit means for receiving, amplifying and decoding a propeller rotation control signal and a rudder motion control signal, which are transmitted at a high frequency from a remote transmitter to respectively cause the propeller to rotate and the rudder to move, and for receiving a high frequency attack signal transmitted by the remote transmitter and separating out the attack signal from the propeller rotation control signal and the rudder motion control signal; and an air-battle box including at least an ultrasonic transmitting tube that transmits ultrasonic waves when said main remote circuit means receives the attack signal, a buzzer, an ultrasonic receiving sensor adapted to receive ultrasonic waves emitted from a further ultrasonic remote airplane, an attachment means for fixing said air-battle box to the airplane, and a control circuit means for controlling the ultrasonic transmitting tube and the ultrasonic receiving sensor; wherein when said ultrasonic transmitting tube transmits the ultrasonic waves, said buzzer is caused to intermittently buzz, to simulate a firing of a shot from said ultrasonic remote airplane; wherein when said ultrasonic receiving sensor receives the ultrasonic waves emitted from the further ultrasonic remote airplane, said buzzer is caused to buzz continuously to indicate the airplane has been shot, and rotation of said propeller is stopped for a predetermined period of time, causing the airplane to fall; and wherein after the predetermined period of time has elapsed, the buzzer ceases buzzing, and the propeller resumes rotation, allowing the airplane to continue flying.
