1. Please stay away from unsafe factors such as obstacles, crowds, and high-voltage lines when flying.
2. Be sure to fly under a safe take-off weight to avoid danger.
3. Please check whether the propeller and motor are installed correctly and firmly, and make sure that the forward and reverse rotating propellers are
installed in the correct position. Do not get close to or touch the rotating motor or propeller during testing to avoid injury from the propeller.
4. Avoid mutual influence or interference between wireless communication devices such as remote control transceivers, on-board WiFi devices, and other
wireless devices.
5. Ensure that the remote control, batteries and all components have sufficient power supply.
6. Ensure to turn on the remote control first, and then start the aircraft. After landing, disconnect the aircraft and battery, and then turn off the remote control.
7. Please be sure to check whether the parts are in good condition. DO not fly if any parts are aging or damaged.
8. Do not use it in places with complex electromagnetic environments, such as near high-voltage lines, near large power equipment, near mobile
communication base stations, and near TV broadcasting towers. This may affect the communication of this product, causing the remote control or image
transmission communication to be abnormal, or affect the aircraft heading judgment and positioning accuracy.
9. Do not fly in severe weather such as strong wind, rain, sandstorm, etc.
10. Please read the instructions carefully, as well as related instructions and videos on the Internet before flying.
Precautions for the use of aircraft

1. An open place with no tall buildings around as the flying field. if it's
near buildings and trees, the GPS signal is relatively weak, and the GPS
fixed-point function and GPS return-to-home function may be invalid.。
2. Do not use in bad weather, such as strong wind (wind speed level 4 and
above), heavy snow, rainy and foggy days.
3. Please stay away from obstacles, crowds, high-voltage lines, trees, water,
etc, while flying.
4. DO not fly in places with complex electromagnetic environment (such
as base stations or transmission towers around), so as not to force the
controller to be interfered with.
5. Can't be used in antarctic and arctic
6. Do not fly in no-fly areas restricted by relevant laws or regulations.
Open place
w/o shelters Good signal Fly in the visual range Fly height under 30 meters
Please stay away from crowds, trees, wires, tall buildings, airports and signal towers when flying. Radio towers,
high-voltage lines, substations, and large pieces of magnetic metal may interfere with remote control signals
and compasses, threatening flight safety
Do not fly in weather such as rain, heavy fog, snow, thunder and lightning, strong wind (wind speed of 10m/s and
above).
Do not fly in no-fly areas

Installation before flying, take out the aircraft, please check whether the aircraft is damaged during transportation, and confirm
whether all the accessories of the aircraft are equipped with.
Adjust the GPS of the aircraft horizontally, the direction of the GPS arrow points towards forwardly, then tighten the screws of the
fixing parts.
Folding
GPS position
Unfolding the arms, tighten the screws of folding parts.
(PS: Ensure tightening the screws after going throught the
rivet, make sure every folding part is tightened.
Note: Pay attention to clean up foreign bodies (such as
sand, dust, etc.) on the folding part while using.

Flight safety notice
It's very important for protecting the safety of surrounding people and the environment with necessary safety instruction of flight.
1. Flying in an open field: pay attention to obstacles such as telephone poles and high-voltage lines while flying, and stay away from water, crowds
and animals.
2. Flying within visual sight: Please keep the aircraft within visual sight at all times, and avoid flying behind tall obstacles that may block the line of
sight.
3. Full control during the flight: Even when using the route operation mode, A-B point operation mode, and automatic return to home, please keep
the remote control in your hand to control the aircraft at any time.
4. Controlling the flying height: To ensure the flight safety of the aircraft and civil aviation, please control the height of the aircraft within 30 meters.
If there are no-flying or flying height restrictions below 30 meters in your area, please follow those regulations.

Calibration of flying

Compass calibration
Power the aircraft with self-check, wait for GPS signal to calibrate the compass. There are 2 methods to do it.
1. Enter APP => Open menu and find sensor => Click “Compass calibration” => When the LEG light is flashing, it means the calibration is started.
2. Push the button of mode up and down for 6 times quickly. => When the LEG light is flashing, it means the calibration is started.
calibration: LED light is flashing Yellow, lifting up the aircraft for rotating 360°horizontally untill Green light is flashing. Then turn to aircraft
vertically (GPS arrow)towards the ground and rotating 360°. When it flashes Yellow, Green and Red, it means the calibration is succeeded. Re-
power the aircraft.
Calibration of flying

Take off
Please install propellers and all fly data are normal, unlock the aircraft with joysticks as picture 1 “↘” “↙” to start motors.
Push up left joystick “↑” to take off.
Landing
Pull down left joystick “↓” until the aircraft is landed. After landed, there are 2 methods to stop motors.
1. After landed, pull down left joystick “↓” to the bottom, pull joysticks as picutre 2 “↙” “↘”to stop motors gradually, release joysticks until heard notice.
2. After landed, pull down left joystick “↓” as picture 3 to the bottom for 3 seconds to stop motors, release joysticks until heard notice.
●If do not take off, please do not unlock the aircraft to start the motor, check if the flight modes and status are normal.
●High-speed rotating propellers are dangerous. When using the aircraft, keep a safe distance and keep the aircraft away from crowds,
buildings or other obstructions.
●Make sure to keep the controller in your hand and ensure that the aircraft is fully controlled before the aircraft motors are stopped.
●During the flight, do not stop the motors, otherwise the aircraft will crash. Unless special circumstances occur, the motor needs to be
stopped urgently to minimize damage.
●After landed, disconnect the aircraft from the power source before turning off the controller. In the same way, the controller must be
turned on before power the aircraft.

Around ground: Select the planned grounds aroundly.
Add new plot: Add a new ground to do spray work.
It can distribute the spray work based on planned grouds, then start to spray.
Or, if a new ground needs to be added, click “⊕ New Plot” , then it show 3 methods as below pictures.
Handheld GPS(RTK) point device: Connect mobilephone with GPS device (Open OTG), then start to add boundary points according to ground.
F l i g h t G P S : Operate the aircraft to add boundary points according to ground.
Map selection: Choose the mapping points of APP to add boundary points according to ground.
Waypoint planning: Use RTK kit and latest firmware of flight control, then add ground with 3D points.
