The positive pole conductive brush and the negative pole conductive brush are both connected to the controller, and the controller is connected to the power source, thereby forming a power supply circuit for the colored lights 25, realizing power supply to the colored lights 25 while the spherical cover 3 rotates.
[0025] In addition, the functions that this utility model can achieve are:
[0026] Realize frequency pairing, that is, pair the flying body 5 with the remote control. The process is as follows: Long press the power button of the flying body 5 for about 2 seconds. The white light at the front end of the flying body 5 flashes, the red light at the rear end stays on, and the green light flashes. Place the flying body 5 on a flat surface. Secondly, long press the power button of the remote control for about 2S. The indicator light of the remote control flashes and makes a "beep" sound. Then push the left joystick of the remote control to the highest point. The indicator light of the remote control flashes and makes a "beep" sound. The front and rear indicator lights of the flying body 5 still flash. Finally, push the left joystick of the remote control to the lowest point. The indicator light of the remote control stays on and makes a long "beep" sound. The front and rear indicator lights of the flying body 5 become constantly on. At this time, it indicates that the frequency pairing of the aircraft is successful. The indicator lights mentioned above do not belong to the spherical cover 3 and are the indicator lights of the flying body 5 and the remote control itself.
[0027] Realize gyroscope calibration: After the flying body 5 is successfully frequency paired, push the left joystick of the remote control to the lower right corner, and at the same time push the right joystick to the lower left corner. At this time, the remote control makes a "beep" sound, and the rear indicator light of the aircraft changes from staying on to flashing and then to staying on, indicating that the gyroscope of the aircraft is successfully recalibrated.
[0028] Realize unlocking / locking: Push the left joystick of the remote control upward, and the four propellers of the aircraft rotate slowly. Push the left joystick of the remote control down to the bottom, and the four propellers of the aircraft stop rotating (push up and pull down).
[0029] Realize one-key takeoff: After successful frequency pairing, press the one-key takeoff / landing button on the remote control, and the flying body 5 takes off and hovers with one key; or in the unlocked state, pushing the throttle can also hover the flying body 5.
[0030] Realize one-key landing: During the flight, press the one-key takeoff / landing button again, and the aircraft will slowly land on the plane and stop the propellers from rotating.
