。A propeller is attached to the model aircraft so that it can rotate freely, and a transmitter that converts the rotation of the propeller into a pulse signal and transmits it is installed, and the pulse signal sent from the transmitter is converted into the rotational speed to transmit the rotation speed of the aircraft. A stall detection mechanism for a flying object in a radio-controlled vehicle, comprising a separate receiver having a circuit that displays the speed and a circuit that converts the pulse signal into an intermittent electronic switch to generate an alarm according to the speed of the flying object. .
