If there are foreign materials, please use alcohol pad or clean insulation to wipe the electrodes (Don't wipe two electrodes at the same time), or the battery charging port will be melted.
Page 15: Function Check
6.2 Function Check After connecting the wire of the system module, it is necessary to check whether the links and functions of each module are normal. The function check must be completed when the propeller are unloaded. The steps are as follows: 6.2.1 Communication Check Turn on the power of the UAV and the remote control (the communication mode of the remote control should be switched to the mode that is compatible with VK-fly,...
Page 16 6.2.2 Remote Control Calibration Compare with the amount of rudder travel of the remote control channels on the APP and confirm whether the amount of rudder travel of the remote control channels need to be reversed. If the definition of pros and cons of the channel is not in accordance with what the APP displays, then the amount of rudder travel need to be reversed in the debug software of the remote control.
Page 17  Put the rocker and the key in the middle position, tap "Calibrate Controller" in the "Calibration" page on the APP or toggle Channel 7 for 6 times to enter calibration mode, the LED light will become purple and it will flash 3 times, which means that it has entered calibration mode.
Page 18 6.2.3 Motor Check ESC Calibration 1） Remove the blades, push the aileron and accelerator of the remote control to the maximum at the same time, and then power on the flight control and the ESC concurrently, the flight control will enter the ESC calibration mode, purple light flashes 4 times.
Page 19 6.2.4 Flight Settings Complete plant protection and flight settings as the figures below. Figure 9 Plant Protection and Flight Settings...
Page 20 6.2.5 Firmware Check Check the firmware version. Make sure the firmware is the latest version. Figure 10 Firmware Version Check 6.2.6 Water Pump/Flowmeter Test In order to achieve precise spray, the flowmeter and water pump should be calibrated before use.
Page 21 Before calibrating the water pump / flowmeter, check the spray system first. For example, add 10L chemical into the chemical tank first, turn on the water pump, and check whether the spray system works normally. If there is air bubble in the water pipe, check whether the pipeline joint is loose.
Page 22 6.2.7 Flight Calibration Voltage Calibration 1） The main battery voltage detected by the flight control system may deviate from the actual battery voltage. At this time, you need to calibrate the voltage. Fill in the real battery voltage on the "Real Voltage" of "Flight Calibration" page, and then tap "Calibrate"...
Page 23 6.2.8 Preliminary Parameter Setting Parameter setting is very important, setting error will directly lead to crash accident. Enter "Advanced", select the four-axis X-shaped plant protection UAV model on the machine model setting page; enter "Algorithm", and ensure that the flight control installation mode is consistent with the actual installation.

Page 25: Debug During Flight
6.3 Debug during Flight 6.3.1 Magnetic Compass Calibration After finishing the installation check, the UAV can be tested in the field. Magnetic compass calibration should be completed before the flight. The calibrating method is as follows:  Toggle the Channel 5 of the remote control for 8 times consecutively or enter the "Flight Calibration"...
Page 26  Rotate the UAV with the head points up. If the indicator light (blue) flashes, it means calibration succeeded; if the indicator light turns red, it means calibration failed, and the UAV needs to be calibrated again. 6.3.2 Debug of Sensitivity For the first flight, please confirm whether the angle of the UAV is correct.
Page 27 ① R / P Gain: adjust the gain in the attitude mode first. The default value of 120 can be adopted (please set this parameter to 100 for the UAV whose blades are more than 30 inches). In the attitude mode, Don't move the bar, observe the self-stability ability of the UAV.
Page 28 vibration of the UAV to a certain extent. If the gain in the basic parameters can't restrain the shake of the UAV, try to set this parameter to 0. Generally, 3 or 4 can meet the flight requirements. This value can be increased steadily only after slight shaking occurs in the middle position when turning the angle back in the attitude mode.

Page 31 6.4.1 AB Mode After A point and B point are defined by the user, AB mode automatically copies AB route for flight. In AB mode, radar terrain-following flight is available; the length of AB route is adjustable during the flight; the flight height and the direction of nose can be adjusted manually.
Page 32 hovering mode, record the coordinates of point B. After the point B is recorded successfully, the LED will flash twice with purple light.  When the recording is completed, toggle Channel 5 switch to AB mode, and then the roll channel gives a left / right full stroke action. At this time, the UAV starts to execute AB mode, and it will fly left / right continuously.
Page 33  Extension of AB Point: when the UAV flies to the edge, move the pitch rocker (push or pull, push at the far end, pull at the near end), and the UAV will fly forward slowly at the speed of 2m / s. When it reaches the extended position, return the pitch rocker to zero, the UAV will stop, and then start to copy the corresponding route.
Page 34  Shorten of AB Point: when the UAV flies to the place that is close to the shorten position, move the pitch rocker (push or pull, push at the far end, pull at the near end), and the UAV will fly forward slowly at the speed of 2m / s. When it reaches the extended position, return the pitch rocker to zero, the UAV will stop, and then start to copy the corresponding route.
Page 35 Take off manually. Turn the Channel 5 switch to AB mode when the UAV is in GPS hovering mode, the UAV will hover at a certain position. Push the pitch channel forward, the UAV will enter the breakpoint resuming mode of AB mode and fly to the place where the UAV exits the AB mode and continue to execute AB mode.
Page 36 6.4.1.4 Obstacle Avoidance in AB Mode Avoid Obstacle Manually 1） When the UAV is operating in AB mode, if it encounters obstacles in front, move the roll bar, the UAV will stop. Then move the roll bar horizontally to a safe value, you can operate the pitch bar.
