[0098] See also Figure 12-14 As shown, the trimming device 200 is arranged at different positions of the fuselage 100, and the uncut corner area thereof is different; among them, the uncut area of ​​the trimming device 200 near the nose is smaller than the uncut area of ​​the trimming device 200 near the middle of the machine; the uncut area of ​​the trimming device 200 near the middle of the machine is smaller than the uncut area of ​​the trimming device 200 near the tail of the machine. Therefore, the trimming device 200 is arranged at the front side of the fuselage 100 as much as possible, that is, near the nose, so that the uncut corner area is smaller when turning.
