An objective of the present invention is to eliminate unnatural behaviors of a wireless controlled airplane during PID control. In a wireless controlled airplane, a receiving section receives a first operation signal for a first actuator, a second operation signal for a second actuator, and a third operation signal for a third actuator, wherein the first, second and third operation signals are provided as operation signals wirelessly transmitted. A first actuator control section is configured to generate an actuation signal for the first actuator by means of PID control depending on the first operation signal, and to reduce an integral element in the PID control depending on an operation value for the second or third operation signal. Alternatively, the first actuator control section is configured to perform switching to a control without an integral element from the PID control.
