3. Open GCS,enter into the start page.

4. Enter into the main page ,see figure 5-2.

5.2 Parameters adjustment

Type 1: Connection by OTG cable



Sensitivity should not be changed by common user,the unnecessary

loss should be taken by user for authorized changing.

 Remote controller could not unlock before parameters adjustment.  Exit could only be done when all of the parameters adjustment should

be done and confirmed.Copter could only fly by restarting after

parameters adjustment.

Parameters could be adjusted when copter connected,the steps are as followings:

1) Open the OTG function from cellphone SETTINGS---SYSTEM---OTG(the default

is Off thus it should be opened every time),see figure 5-2-1.

24

Figure 5-2-1

Connect cellphone with Micro USB port of remote controller.The connection method

Leave the copter in a horizontal position,click the button ACCELEROMETER,LED will

flash in red,green,yellow alternately,LED green means successful calibration,data will be

stored by restart.

31

5.2.3 Compass calibration

Calibration order

Two kinds of method of compass calibration:

1) Click the button COMPASS to enter into calibration status.

2) Switch switch SA back and forth more than 4 times to enter into calibration status.

Calibration Step

1) Confirm GCS communication well, compass installation correct and copter outside.

2) Clicking calibration, yellow LED of copter is on, hold and keep copter rotating

clockwise and slowly, leave copter head to the ground when green led is on, rotate

copter clockwise and slowly till LED flash in red,green and yellow alternately.

32

3) After vertical calibration,calibration mode will be exited automatically and LED will

flash normally if successful, LED will keep red for 3 seconds if fails and recalibration

4) Please power again after successful calibration.

Attention：

1) Compass should be done after changing flying area.

2) Calibration should be done in outdoor,wild and far away from high tension line tower

3) Keep horizontal and vertical during the slow calibration.

4) Clockwise is the only direction.

5.2.4 Flying parameters adjustment

should be done.

which is easy influenced by magnetic interference.

Click the button READ to obtain the current flying parameters,click button SAVE to save

the parameters.

33

The default number of back landing height is 20 meters,AB swath is 4 meters,route speed

5.2.5 Low voltage protection

is 5m/s.

5.2.5.1 Low voltage protection settings

Five voltage protection has been provided:close,return to home point,hovering,auto

landing,hovering and then landing. User could choose the one suitable.The default is

auto landing.

5.2.5.2 Alarm voltage settings

Settings of first alarm and second alarm.It’s recommended to 43.6V for the first

alarm and 43.1V for second alarm.

LED will flash yellow triple when get to the first alarm level;LED will flash rapidly when

get to the second alarm level,copter will react as the low voltage settings,such as return to

home or landing.

34

5.2.5.3 Voltage calibration settings

Flight controller voltage sensor need to be calibrated if flight controller voltage sensor

result is different from real voltage.Real battery voltage should be filled in measured

voltage,flight controller voltage will be calibrated by clicking save. It’s unnecessary to set

by user as calibration has been done before delivery.

5.2.5.4 Pump and liquid level sensor settings

5.2.5.5 Tank empty reaction

The following reaction could be set:close the pump,return to home

point,hovering,hovering and then landing.The default is close the pump,which means only

LED flash as alarm.

Spraying settings

Combination control of the pump,max flow rate match to max flying speed. The

maximum default combination number is 6m/s,minimum default combination number is

0.2m/s.

AB mode is a more simple efficient mode with fault tolerance to operate.The working

theory is above in the picture.Record the point A and B,the UAV will plan the flight line like

this.

1. Operate Steps:

48

1) Record the point A,switch the mode to GPS mode.Until the drone self-hovering

steadily,switch SD to ”Point A memorized”.After that,the LED flash yellow for 2

2) Record the point B,drive the drone to the position you want,be sure it is at least 10

3) Select the direction,switch SA (Flight mode) to AB mode, move the roll joystick to

4) AB Mode Correction

5) Shut Down and Quit

meters away from point A.Until the drone self-hovering steadily,witch SD to ”Point B

memorized”.After that,the LED flash yellow for 2 seconds.The controller have voice

prompt.

select the roll direction.Move the joystick to the left limitation,the drone rolls to the left

side,move the joystick to the right limitation,the drone rolls to the right side.While the

drone doing AB point flight mode,the user can stop controlling the joystick.Make sure

that the water enough,the pump is under auto-controlled or manual-controlled.

①Altitude correction:Control the flight altitude by the throttle joystick, “up” for the

drone to rise, the “down” for the drone to set ;

②Correct the the rudder to control the direction;

③Fix point A:while the drone moving from point B to Point A,push up the pitch stick to

make point A 1m closer to point B,push down the pitch stick to make point A 1m

away from point B.

④Fix point B:while the drone moving from point A to Point B,push down the pitch stick

to make the point B away from point A,push down the pitch stick to make point B

1m closer to point A.

①When set the “no pesticide” action to self-hovering or return,in AB mode this

function still

works.

6) To return to the breakpoint, shut down the AB mode auto-controlled or manual-

1) Be sure to start AB mode within turning on the pump and agitation function working.

2) Be sure it is at least 10 meters away from point A to point be.

3) Every time recording point A and B,be sure to wait until the drone self-hovering

4) Without removing last AB point,can not set new AB point.

②When set the “low battery” action to return,in AB mode the this function still works.

③After the spraying work is done,AB mode can be shut down by switching into

altitude mode.

controlled. After filling the pesticide in the tank and taking off,switch SA (flight mode)to

AB mode directly ,the drone would return right to the breakpoint.

2. Remove Point A and B

Move stick SD (AB mode) for 4-5 times rapidly,LED alternately flash red green and

yellow,AB mode removed.Without removing last AB point,can not set new AB point.

3. Set the Interval Width

From the software->Flight parameters to set the spraying width and working speed

Attention:

steadily in GPS mode.

Appendix II How to connect copter to PC GCS

3 One connect to computer,another end connect to copter.Waiting for a moment(It takes

few minutes to install the driver for the first connection with a new computer),see figure 3:

1 Unscrew the 8 pieces of bolt and open the upper cover,see figure 1:

2 Find the computer connection cable from the attached bag,see figure 2:
