When the user switches the present invention to activate to the auto pilot unit 441, the auto pilot unit 441 sets an automatic flying route, a target spraying area, and a height of flying based on the geographic position information, such that the flying device 10 automatically flies to the target spraying area according to the automatic flying route and the height of flying and sprays the pesticide 34 at the target spraying area. When the user switches the present invention to activate the manual pilot unit 442, the manual pilot unit 442 is manually controlled to drive the flying device 10 to fly to the target spraying area.

In addition, the control module 41 of the controller 40 is electrically connected with the air valve adjust module 22 of the air valve 20 and the electromagnetic control valve 33 of the spraying device 30 for controlling the power strength of the air valve 20 and the ON and OFF status of the electromagnetic control valve 33.

Referring to FIG. 4 and FIG. 7, when the electromagnetic control valve 33 is practically turned ON, because of the pressure of the gas cylinder 21 is larger than the pressure of the nozzle 32, the gas power of the air valve 20 simultaneously delivers the pesticide 34 in the pesticide container 31 to the diverting member 35. Finally, the pesticide 34 is sprayed through the nozzle 32. With such gas powered spraying method, the overall weight of the flying device 10 is greatly reduced, so as to improve the flying stability of the flying device 10.

A remote control device 50 includes an operate module 51 and a wireless communication module 52 electrically connected with the operate module 51.
