(1). Electric Speed Control(ESC) Calibration
The drone has been calibrated when it leaves factory, but if the motor speed is
obviously inconsistent during the later flight, please calibrate the drone again as follows:
Step1:Power on the drone and push throttle joystick to top, then LED indicates the
current GPS status and flight mode
Step2:Toggle SD quickly for 6-10 times from top to bottom until LED light up in RED.
Step3:Hold the throttle joystick, plug drone power off and then power on, the LED
will flash once in turn of RED, GREEN and BLUE.
Step4:After power on for about 0.5 seconds, the drone will “DiDi” sound twice.
pleasepull the throttle joystick to bottom in 2 seconds,and drone will
“DiDi”sound twice again. LED will flash in RED and Blue normal status.

(2).Horizon Level Calibration
The drone has been calibrated when it leaves factory, if it tilts seriously towards
certain direction during later flight, please calibrate the drone again as follows:
Step1：Put the drone on horizontal ground, make sure it doesn't shake.
Step2：Lock the drone by holding the joysticks like second diagram for 10 seconds
until LED flash alternately in BLUE and GREEN.
Step3：Release the joysticks, LED will flash in BLUE about 10 seconds later, and
then LED will flash normally after 15 seconds.

(3).Compass Calibration
Compass calibration is required when the aircraft takes off first time or changes
location (50KM from the last flight position). The calibration method is as follows:
Step1：pull throttle joystick to bottom.
Step2：Toggle SD quickly for 6-10 times from top to bottom until LED light up in BLUE.
Step3：Place the drone head facing forward horizontally, slowly turn the drone
clockwise at least one round until the LED green light is on
Step4：Place the drone head down, fuselage vertical, and then slowly turn
clockwise at least one round until the LED light up in WHITE for 4 seconds.
If the LED light up in RED for 4 seconds, indicating calibration failure, repeat steps
2-4 until succeed.

(1).Gesture mode
In gesture mode, without too much data to calculate, the drone respond fast but cannot
Hover at fixed-point, this mode is suitable for skilled pilot.
(2).GPS mode
With good GPS signal, the drone can hover at fixed-point in GPS mode.
(3).Spray mode
Spray mode is based on GPS mode, only with good gps signal, user can enter this mode.

Agriculture Drone User manual Agriculture Drone User manual
Step1：Fly the drone to the start point, switch SD to Spray Mode and SC to Spray On
then push or pull the direction joystick over 15% from the middle position, the
drone will spray in uniform speed and fixed height.
Step2：When the drone fly to a line change point, release direction joystick back to
middle position, now the drone will hover. pull direction joystick left or right and
then middle, it will fly to the start point of next line.
Step3：Repeat step 1-2 to finish the spray work .
During spraying, the height can be adjusted accordingly, the drone will fly at fixed
height when throttle joystick stay at the middle position.
Spray flow rate associated with the flight speed of the drone, the greater the speed
the greater the flow; it will stop spraying when speed is less than 0.5 m/s.
(4). A-B Point Mode
A-B point mode is a fast automatic route planning mode, users need to confirm the GPS
signal is good. methods are as follows:
A
B
Operating inter val
Route L
Step1:Fly the drone to start point A, SA switches from STANDBY to “RECORD POINT
A”position,then the drone will record point A gps coordinate, LED will flash 10
times in RED (10)
Step2：Fly the drone to Point B position, SA switches to “RECORD POINT B”position,
then the drone will record point B gps coordinate, LED will flash 10 times in
GREEN (10)
Step3：Switch SB to A-B MODE, LED flash 8 times in BLUE (8), pull direction joystick
left or right and then middle, it will fly to the start point of next line and then fly in
route L and spray in uniform speed and fixed height.
Step4：Quit A-B MODE when finish spraying, the drone will hover.
• Only in spray mode or GPS mode can record A and B point.
• A-B mode is not available when the drone is on ground.
• During operation, the LED flashes 3 times in RED (3) when flying to point A, and
then flashes 3 times in GREEN (3) when flying to point B.
• Erase A and B point: 1) Exit A-B mode, re-record the A and B point; 2) Toggle SA up and
down 8times and LED will flash 10 times in YELLOW (10); 3) A and B point will be
erased when erase the pesticide break point(refer to next page); 4)If pesticide
breaking point has not been recorded , A and B point will be erased automatically when
the drone land and auto locked.
The drone has dose detection function, when the dose is insufficient, the drone will
record breaking point, and will automatically fly to the breaking point to restart spraying
after reloading pesticide. Dose sensor switch interface is as the following figure, you can
disconnect it and cancel the dose detection function.
9. Restart At Pesticide Breaking Point
Two interfaces: Green is for battery power
of the pump, RED is for dose detection
Step1：When low dose is detected, the aircraft will decelerate, automatically rise 1.5
meters and hover (Gesture / GPS mode will not rise), record the current
position, LED flash 4 times in light blue (4), in the process of rising , you can
switch SD to stop rising, the drone still records pesticide breaking point.
Step2：When finish rising, the drone will hover, you can manually operate the drone to
return or press the auto return switch(if HOME position recorded).
Step3：After reloading, the drone will automatically rise to the 2.5meter height and fly
back to break point, and then drop to the operating height and restart spraying
(you can pull throttle joystick to stop dropping).
• If the drone record the breaking point, pull the throttle up to 70% and then back to
middle when it is rising, and then it will automatically fly back to the breaking point and
restart spraying.
• Spray mode, A-B mode, gesture mode and GPS mode all allow record breaking POINT,
but automatic flight back to the point is NOT available in gesture mode.
• Toggle SD 4 times can erase the current breaking point. Also it will clear automatically
After drone landing and locking for 15 minutes.

Agriculture Drone User manual Agriculture Drone User manual
Only when the GPS signal is good and return landing position has been record
before flight starts (LED will flash 10 times in BLUE if recorded (10) ), can the drone
receive return command, method as follows:
Step1：Switch SC to RETURN position, the drone will automatically rise 1.5 meters and
hover, (will not rise in gesture mode or GPS mode), and record the breaking point.
Step2：Toggle SC once and back to RETURN position, the drone will rise up 2 meters
and then return.
Step3：Restart the drone (refer to method of restart at pesticide breaking point). the drone
will automatically rise to the 2.5meter height and fly back to break point, and then
drop to the operating height. (user can pull throttle joystick to stop dropping)
10. Return Command
If remote control signal lost, LED will keep flash in YELLOW and BLUE (∞ ),
after hovering for 5 seconds, the drone will return to the take-off position, land and lock .
if the signal recovered during return flight, it will stop returning and switch back to RC
current SD mode.
11 Out of Control Protection
During flight, battery voltage PWR will be displayed real-time on remote control
screen (display position as below configure). When drone battery voltage is lower than
43.5V, remote control will give voice and vibration alarm. The drone can last about 2
minutes at this time, please land the drone in time and replace batteries.

press the blue piece when
connect/disconnect the pipe
press the blue piece when
connect/disconnect the pipe
Step1:turn on the remote control and then power on the drone.
Step2:after LED flash( )(10),make a compass calibration (please refer to page 6).
Step3:after the calibration is complete, install the propellers correctly.
Step4:wait for GPS signal search, LED will flash singly turn from RED to GREEN if succeed.
Step5:check if the LED flash correctly according to the correct flight mode.
Step6:step away from the drone for at least 5 meters, unlock the drone and start flying.
16. First Flight
• Please disconnect the dose detection cable or clear the pesticide breaking point
before the compass calibration, in case it may record a wrong breaking point because of
unloading.
• Please operate the joysticks slowly.
• Please keep SA, SB, SC in STANDBY mode before unlocking the drone.
