The drive shaft 60 includes a motor 61 disposed in a hollow space at the bottom of the cylinder 42. The motor 61 has a drive shaft 62, and the drive shaft 62 passes through the hollow space of the cylinder 42. Connect the snail Rotary paddle 50. Therefore, when the motor 61 rotates, its axis will drive the propeller 50 to rotate; the motor 61 is connected to the inside of the body main body 10 by a wire 63.

The body 10 includes a power control unit 70, and the power control unit 70 includes:

A circuit board 80; the circuit board 80 includes a controller 81 for controlling the rotational speed of the motor 61. The circuit board 80 is connected to the wire 63, and the wire 63 is connected to the motor 61 through the hollow space of the support rod 30.

A battery 90 is placed at the bottom of the fuselage body 10 for providing the power required to operate the fuselage body 10. The positive and negative electrodes of the battery 90 are connected to the circuit board 80. The body main body 10 has a battery cover 11.

A switch 100 is located on the surface of the body 10 for opening or closing the operation of the power control unit 70. The switch 100 is connected to a wire 101 which is connected to the circuit board 80.

A wireless transceiver 110 is coupled to the controller 81 for receiving an external wireless signal and converting the wireless signal into a current signal that controls the speed of the motor 61, and controlling each motor 61 such that the aircraft exhibits various flights. the way.

A controller 120 is configured to send wireless signals to the wireless transceiver 110 to control the flight mode of the airframe body 10. The controller 120 drives each of the propellers 50 to generate a corresponding rotational speed by controlling the rotational speed of each of the motors 61, so that The air pressure around the fuselage body 10 changes, and the fuselage body 10 can be produced in a variety of different flight modes. The controller 120 includes:

A power rod 200 is used to control the rotational speed of the motor 61 of the front screw body 20 and the rear screw body 21 so that the body main body 10 can perform a flying motion of ascending, descending, horizontal clockwise, and horizontal counterclockwise rotation. The power rod 200 can be pushed up, down, left, and right, respectively corresponding to the flying motion of the body main body 10 rising, falling, horizontal counterclockwise, and horizontal clockwise rotation.

A set of lifting and lowering correction buttons 210 and 220 are used for correcting the rotation speed of the motor 61. When the rotation speed of the motor 61 is abnormal, so that the body main body 10 assumes an abnormally rising or falling state, the lifting correction knob 210 can be passed through each of the lifting and lowering correction buttons 210. The 220 is corrected in the reverse direction to restore the flight state of the body main body 10 to normal. For example, when the user presents a rising state without pushing the power lever 200 upward, the motor 61 of the body main body 10 can be reversed through the elevation correction knob 220.

For example, when the user does not push the direction bar 300 to the right, the body main body 10 can reverse the direction of the motor 61 of the body main body 10 through the direction correction knob 330. The rotational speed adjustment causes the body main body 10 to move right to offset the original left shifting state, and corrects the flight mode of the fuselage main body 10 to a state of stable non-leftward shifting.

A shift button 400 is used to switch the flying speed of the body main body 10. The shift button 400 controls the rotational speed of the motor 61 to cause the body main body 10 to change its elevation angle to change the flying speed of the body main body 10. The shift button 400 has a plurality of fixed angle elevation angles for the user to switch, and the body main body 10 can be switched to generate a corresponding flight speed.

A flip button 500 is used to instantaneously increase the current of the motor 61 so that the rotational speed of the motor 61 is instantaneously increased, so that the body main body 10 generates a forward tilt, a backward flip, a left flip and a right flip motion in a vertical direction of 360 degrees. For example, when the user clicks the flip button 500 and pushes the direction bar 300 upward, the rotation speed of each motor 61 of the rear screw body 21 is instantaneously increased, and the body main body 10 is caused to have a vertical direction 360. The degree of forward movement.

A controller wireless transceiver 121 is configured to send wireless signals to the wireless transceiver 110 to control the flight mode of the fuselage body 10.

A controller power switch 122 is used to turn the operation of the controller 120 on or off.

In this case, the battery 90 is first placed in the body 10, and then the switch 100 is turned on to start the operation of the wireless transceiver 110. Then, the controller power switch 122 of the controller 120 is turned on. At this time, the controller wireless transceiver 121 of the controller 120 transmits a detection signal to the wireless transceiver 110 of the body 10 to make the airframe. The body 10 can start receiving subsequent control signals of the controller 120, and control each of the motors 61 to drive the propellers 50 at different rotational speeds, so that the fuselage body 10 produces various different flight modes. The user can control the lifting height and the horizontal rotation of the body 10 via the power lever 200, or can control the front, rear or left and right movement of the body 10 via the direction bar 300, or via the shift button 400 and the The flip button 500 causes the body main body 10 to be accelerated and vertically flipped, respectively. In addition, when the fuselage body 10 has an abnormal flying state, the user can also pass the lifting and lowering correction buttons 210 and 220, the rotation correcting buttons 230 and 240, and the respective direction correcting buttons 310, 320, 330, and 340.
