An ultrasonic remote aeroplane for playing air-battle game includes a wing, a cockpit, a propeller, a tail pole, a fin, a rudder, a main remote circuit for receiving the propeller rotation controlling signal and rudder motion controlling signal carried high frequency carrier transmitted from a remote transmitter, and a driving system thereof. The remote aeroplane further includes an air-battle box including at least an ultrasonic transmitting tube, an ultrasonic receiving sensor, an attachment structure for fixing to the aeroplane, and a control circuit corresponding to them. The remote transmitter further transmits a high frequency carrier carrying a signal F3 for instructing the ultrasonic transmitting tube to transmit ultrasonic waves. The main remote circuit further includes a circuit for receiving the high frequency carrier carrying the signal F3 and separating out the signal F3.
