In the operation of the drone before the flight to do a good job on the drone of the various checks, any one of the drone problems may lead to flight accidents, the following we will take the multi-rotor aircraft as an example to learn the drone takeoff before takeoff takeoff and takeoff need to pay attention to the inspection matters. What are the inspections before takeoff of multi-rotor UAV?

1. The antenna position of the remote control, the position of each switch, the position of the throttle stick, check the battery voltage after opening the remote control, the transmitting system, the name of the model, whether the fine-tuning position is correct, and whether the timer is cleared to zero.

2. Whether the folding mechanism of each axis arm is locked or not, and whether all the fixing screws of the fuselage are loosened or not.

3. Whether the propeller of each axis is installed in the right direction and locked firmly, whether the propeller is broken, whether the motor rotates smoothly, whether the motor and the motor base are fixed firmly, whether the fixing screws of the motor base and the carbon tube are loosened.

4.Whether the GPS support rod is locked, whether the GPS and magnetic compass bottom double-sided adhesive fixed firmly, magnetic compass arrow direction to confirm no displacement.

5. Whether there is loosening and oxidization of electronic equipment plugs and welding joints, whether the anti-loosening mechanism of plugs and sockets is installed in place, and whether the banana head of the power socket is ablated.

6. Check whether the voltage of the battery to be installed on the multi-rotor is fully charged by using a measuring device, check whether the center of gravity of the multi-rotor is correct after the battery is installed on the aircraft and the battery is fixed firmly by using a battery strap, check whether the battery voltage is fully charged by using the ground station after the ground station confirms that the flight control is powered on, and check whether the battery voltage is fully charged again by using the ground station; if using the cell phone ground station or the PC ground station, you need to pay attention to whether the remaining power in the ground station can satisfy the time requirement of the operation task. If you are using a cell phone ground station or PC ground station, you should pay attention to whether the remaining power of the ground station meets the requirements of the operation mission time.

7. Power on and check whether the task load is working normally.

8.GPS search for more than 7 stars, check whether the “attitude angle” is correct in the stationary state, lift the body to do pitch and lateral movement to check whether the attitude angle is correct, and whether the LED indicator flashes normally.

9. Toggle the switch to check whether the “flight status” can be switched between “manual” and “auto hover” through the ground station. Toggle the switch to check whether it can switch between “auto navigation” and “auto return” through the ground station. Make sure that the channel settings are correct through the above checks, and reconfirm that the LED indicators correctly indicate the working status.

10. Turn off the remote control to check whether the runaway protection is working, and check whether the “flight status” is switched to “auto-return” in the ground station, and then turn on the power again.

11. Determine whether the power voltage is full or not through the ground station, 6S full voltage is about 25.2V.

12. Check whether the hand control rudder position is normal.

13. Set the “Initial Voltage Alarm Value” to 3.65V for operation and 3.7V for practice flight.

14. Make sure the “Aircraft Type” corresponds to the actual multi-rotor type, if the setting is wrong, you can't take off.

15.Push down the very low speed throttle after unlocking in “manual” state, let the motor just start to rotate, and check whether the motor rotating direction is correct and whether the motor mixing control action is correct in the low speed state.

16,Confirm the safety of the flight airspace, before taking off, make sure the onlookers are behind the pilot, and the multi-rotor is more than 5 meters away from the pilot before taking off.

If the white light flashes during the flight of the multi-rotor UAV, the multi-rotor should be allowed to return to the hovering state, if the white light continues to flash. Purdue International Aviation Technology (Dongguan) Co., Ltd. is located in the new first-tier city of Dongguan City, Wanjiang District, is a collection of research and development, production, sales, training as one of the drone integrated service platform, the company's products mainly include aerial photography drones, military drones, multi-rotor drones, emergency rescue drones, vertical take-off and landing fixed-wing drones, and other types of aircraft.
