(57) [Abstract] (with amendment)

[Problem to be solved] To provide a drone that is capable of applying pesticides and the like with stability, with minimized effect of wind pressure.

[Solution] A mounting hole 6 is formed in the center section of an airframe 1 for a tank 7 filled with pesticides and the like, and the tank 7 is inserted in this tank mounting hole 6 in such a manner that the tank 7 is placed in the tank mounting hole 6 from above the airframe 1, and then fits the tank mounting hole 6. Upon this process, an upper part 7a of the tank 7 is exposed on the top face of the airframe 1, and the tank 7 is filled with one half of a chemical agent, with the center of gravity of a drone set to be within the range of imaginary lines drawn from the center points of rotation of each of propellers 9 at an angle of 10 to 20 degrees downward from the center lines between each of the propellers.

[Claims]

[Claim 1]
A remote controlled unmanned aerial vehicle characterized by:
a tank mounting hole for mounting a tank filled with a chemical agent, wherein the tank mounting hole has been formed in the center section of an airframe, the chemical agent tank has been placed in the tank mounting hole from above the airframe and fixed into this tank mounting hole, and the upper part of this chemical agent tank is exposed on the top face of the airframe; and
the said chemical agent tank filled with one half of a chemical agent, wherein the filling has been done while the chemical agent tank is fixed, and the center of gravity of a drone is set to be within the range of imaginary lines drawn from the center points of rotation of each of propellers at an angle of 10 to 20 degrees downward from the center lines between each of the propellers.

[Claim 2]
The remote controlled unmanned aerial vehicle according to Claim 1, characterized in that the said tank is filled with an agricultural chemical agent, and in that the drone is used to apply the chemical agent.
