[0029] Please refer to Figure 3 and [[ID=1⒉]] Figure 4 wherein, Figure 3 is a three-dimensional assembly schematic diagram of the central support assembly, motor and servo of the helicopter provided by the present utility model, Figure 4 is Figure 3 the exploded schematic diagram of the central support assembly and the servo shown. The present utility model provides a helicopter, which includes a central support assembly, a motor 50 and a servo 60. The central support assembly includes a central support 20, a support frame 30 and a mounting bracket 40. The central support 20, the support frame 30 and the mounting bracket 40 are fixedly arranged in sequence. The motor 50 is fixed on the side of the central support 20 away from the support frame 30. The transmission shaft of the motor 50 penetrates through the support frame 30 and the mounting bracket 40. One end of the servo 60 is fixed to the central support 20, and the other end is fixed to the mounting bracket 40.

[0030] Please refer to Figure 5 which is Figure 3 the three-dimensional structure schematic diagram of the mounting bracket shown. The mounting bracket 40 includes a body 41 and a connecting arm 42. The connecting arm 42 extends from the body 41 in a direction away from the body 41 and includes at least two groups of mounting hole groups 420 arranged along a preset mounting direction, which are matched with at least two different sizes of the servo motors 60.

[0031] It can be understood that the number of the connecting arms 42 can be one or more, such as two, three, four, etc. When the number of the connecting arms 42 is multiple, the multiple connecting arms 42 can be arranged in axial symmetry or central symmetry. Each set of the mounting hole groups 420 can include one mounting hole or multiple mounting holes. When a set of the mounting hole groups 420 includes multiple mounting holes, the multiple mounting holes in the same group are arranged according to a preset relative position between each two of them.
