Assembly &Configuration

Step

1

Assembly

Install the autopilot system and receiver to the aircraft, and connect them according to the following diagram.

Refer to the Port Description for more details.

GPS/COMPASS

· GPS/Compass is sensitive to magnetic interference, should be far away from any electronic devices.

· You should use epoxy resin AB glue to assemble the GPS bracket first as the figure showed in previous page.

· Mount the bracket on the center plate of craft first, then fix the GPS on the plate of the bracket (by 3M glue provided). The GPS is sensitive to vibration interference, so position the bracket at least 10 cm from any rotor.

The DJI logo marked on the GPS should face the sky, with the orientation arrow pointing directly forward. The GPS/Compass is packaged with a special indication line for mounting for the first time.

If you are uncertain whether materials near the GPS/Compass module are magnetic or not, you can use a compass or magnet to check it. If you use your own mounting rod, make sure it is NOT magnetic!

PMU & Battery

·

There is no requirement for

·

·

PMU mounting.

Use our PMU Connecter (red line depicts in figure) to connect battery, PMU and ESCs.

You can choose 2S-6S LiPo battery.

For safety reason, please disconnect ESCs and battery connecter during the firmware upgrade and configuration procedure.

Sufficient air flow over the

PMU is highly recommended.

LED Indicator

·

Place The LED indicator at an appropriate location of craft body far away from the GPS. Do not mount it on other electronic devices.

·

Make sure You can see

· the light during the flight.

You can connect LED to the CAN-Bus port on

GPS connection wire.

·

Please refer to the "LED

Description" in the

Appendix to know the details of LED blinking method.

IMU

·

The IMU is best positioned near the multi rotor’s center of gravity, where vibration is relatively low.

·

Orient the IMU such that the arrow marked on the printed surface of the

IMU faces the sky and points directly forward, backward, left or right.

·

The sides of the IMU should be precisely parallel to the multi rotor body. Use double-sided foam tape for secured installation.

DO NOT cover the ventilation holes, keep them unobstructed.

DO NOT mount the IMU upsidedown.

Check the double faced adhesive tape regularly to ensure that the

IMU is securely positioned.

The IMU module is NOT waterproof or oil-proof.

Main Controller

·

There is no orientation requirement for the Main

Controller. Choose a mounting location where as shorter ESC extension wires are needed as possible. Please make sure all ports are accessible when installing the MC so as to facilitate wiring and software configuration.

·

In three-pin ports, pins near the nicks are signal pins.

·

After choosing a location to mount the MC, it is recommended that you DO NOT mount the MC until all wirings and software configurations are completed.

ESC & Motor

·

Please make sure you are using the ESCs and motors recommended by the manufacturer of your multi rotor first. We recommend you use DJI motors and ESCs.

WKM output is 400Hz refresh frequency.

·

Connect all ESCs to MC by the motor numbering method introduced in Multi-Rotors

Supported .

·

If you use 3rd party ESCs, please make sure the ESCs travel midpoint is at 1520us.

·

DO NOT use 700us travel midpoint ESC, as it may lead aircraft to fly away or cause injury and damage. After connect ESCs, calibrate ESCs one by one through the receiver directly before connect them to your MC, Make sure program all of them into

Governor off, Break off and Normal Start up to get best experience.

If you use 3rd party ESCs, please cut the red wire (power wire) of your ESCs , as the power from V-SEN on PMU is suitable to most of receivers and other electronic devices.

·

If you use extra BEC, please use a servo cable without power wire to connect V-SEN to X1. (Not recommend)

Compass Calibration

Without GPS module, please skip this step. If you use with GPS module, follow step-by-step for calibration.

 DO NOT calibrate your compass where there is strong magnetic interference, such as magnetite, car park, and steel reinforcement under the ground.

 DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones.



Compass module CANNOT work in the polar circle.

Calibration Procedures

1. Quickly switch the control mode switch from GPS Mode to Manual Mode and back to GPS Mode for 6 to

10 times. The LED indicator will turn on solid BLUE.

2. Rotate your Multi-rotor around the horizontal axis (about 360 o ) until the LED changes to solid GREEN, and then go to the next step.

3. Hold your Multi-rotor vertically and rotate it (its nose MUST be downward) around the vertical axis (about

360 o ) until the LED turns off, meaning the calibration is finished.

4. The LED indicator will show whether the calibration is successful or not.

 If the LED keeps WHITE for 3 seconds, meaning the calibration is successful, and then calibration mode will exit automatically.

 If the LED keeps flashing quickly RED, the calibration has failed. Switch the control mode switch one time to cancel the calibration, and then re-start from step 1.

1. You don’t need to rotate your multi-rotor on a precise horizontal or vertical surface, but keep at least 45° difference between horizontal and vertical calibration.

2. If you keep having calibration failure, it might suggest that there is very strong magnetic interference around the GPS & Compass module, please avoid flying in this area.

3. When to do re-calibration.

 The flight field is changed.

 The multi-rotor mechanical setup has changed, including the following situations: a) If the GPS & Compass module is re-positioned. b) Electronic devices added, removed or re-positioned (Main Controller, servos, batteries, etc). c) When the mechanical structure of the multi-rotor is changed.

 If the flight direction appears shifting (meaning the multi-rotor doesn’t “fly straight”).

 The LED indicator often indicates abnormality blinking when the multi-rotor spins. But it is normal for this to happen only occasionally.

 LED blinks yellow and green (


8 |

) continually, indicating that the compass data is abnormal.

Basic Flying Test

Step

1

About the Control Mode Switch

The autopilot system can work in Manual Mode and ATTI. Mode without a GPS module. After connecting to the

GPS module, GPS Mode is available. Follow the bellow steps to enter the different control modes.

1.

2.

Use a 3-position switch on the transmitter as mode control switch.

Make sure to take off the aircraft in ATTI. Mode in every flight.

3. Hover the Aircraft. Release all joysticks and then flip the control mode switch to the GPS Mode or Manual

Mode (NOT RECOMMENDED).

Step

2

Start & Stop Motor

Star Motor ：Pushing throttle stick before takeoff will not start motors. You have to execute any one of following four Combination Stick Commands (CSC) to start motors

Stop Motor ：The default setting of stop motor is Immediately. For the immediately mode, in any control mode, once motors start and throttle stick is over 10%, motors will stop immediately when throttle stick is back under 10% again.

In this case, if you push the throttle stick over 10% within 5s after motors stop, motors will re-start, CSC is not needed. If you don’t push throttle stick after motors start within 3s, motors will stop automatically.

Please refer to the instructions of A1 and A2 in the Advanced Functions section, to learn more about

Setp the Control Mode and Stop Motor details.

3

Checking List before Flying

 Make sure you have assembled your multi-rotor correctly.

 Make sure you have done the configuration procedure correctly.

 Make sure all connections are in good condition.

 Make sure batteries are fully charged for your transmitter, autopilot system and all devices.

 Any of the following mistakes will lead to a dangerous accident, double check all these items:

Rotation direction of motor is opposite / Propeller installation mistake / Main controller installation mistake / Wrong connection between the main controller and ESC.

 Always switch on the transmitter first, then power on multi-rotor! (Power off multi-rotor first, then switch off the transmitter after landing!)

 Make sure the GPS signal is good, only one Red LED blinking or without Red LED blinking.

Otherwise multi-rotor will drift without stick commands.

 When system is powered on, you MUST NOT move your multi-rotor or sticks on transmitter until the system initialization is finished (about 5 second).

 Please AVOID using the autopilot system in areas of urban area with crowded buildings, tunnels and under bridges, where GPS signal will be blocked most likely.

 In ATTI Mode, throttle stick center position is for 0m/s along the vertical direction. You should keep the position of throttle stick higher than 10% from cut-throttle during the flight!

 Please do the fly test and gain tuning with ATTI. Mode in the open air without heavy wind!

 Refer to the indication in the software: Basic->Gain for more details.

Step

4 Flying Procedures

1. If in GPS Mode, place the aircraft in an open space without buildings or trees. Take off the aircraft after 6 or more GPS satellites are found (RED LED blinks once or no blinking). If in Manual Mode or ATTI. Mode, you can skip this step.

2. Place the aircraft three meters away from you and others (especially child), to avoid accidental injury.

3.

Start-up

 Switch on the transmitter, and then power on autopilot system! You MUST NOT move your multi-rotor or sticks on transmitter until the system initialization is finished (about 5 second).

 Push both sticks of transmitter to the left bottom or right bottom to start the motors.

 Release the yaw, roll and pitch sticks and keep them at the neutral position, avoiding the aircraft to tilt to one side. At the same time raise the throttle stick from the bottom quickly. The motors will stop if you do not push the throttle stick from the bottom within 3s and you will need to execute the start-up procedure again. When the aircraft is on the point of leaving the ground, continue to push the throttle stick upwards to take off from the ground, pay attention not to push the stick excessively.



Pay attention to the aircraft movement at any time when flying, and use the sticks to adjust the aircraft’s position. Keep the yaw, roll, pitch and throttle sticks at the neutral position to hover the aircraft at the desired height.

4.

Lower the aircraft slowly. Pull the throttle stick to the bottom and then push the sticks to the left bottom or right bottom to stop the motors after landing. (Also, with throttle stick under 10%, and after landing 3s the motors will stop automatically)

5.

Power off the autopilot system, and then switch off the transmitter after landing.











DO NOT fly near to any ferromagnetic substances, to avoid strong magnetic interference with the GPS. Otherwise, it may cause the aircraft to FailSafe, crack or even fly away.

If abnormal compass data occurs during flying, LED will blink Yellow and Green alternatively

( ). If in ATTI and Manual Mode, it is free from influence. In any other control mode, the autopilot system will enter into ATTI. Mode automatically; once the compass data goes back to normal, the autopilot system will regain the original control mode.

If the LED flashes quickly YELLOW then this indicates battery voltage is low, land ASAP.

It is recommended to land the aircraft slowly, to prevent the aircraft from damage.

If the transmitter indicates low-battery alarm, please land ASAP. In this condition the transmitter may cause the aircraft to go out of control or even crash.

The LED will blink White to indicate huge cumulative yaw errors caused by spinning the craft continuously. In this case, you can stop or slow down the spinning, and continue flying after the

White blinking has stopped, so as to have better flight performance.

If Low-Voltage Alarm is set, the aircraft will act according to the configuration of the Assistant

Software once Low-Voltage Alarm is triggered.

If Fail-Safe function is set, the aircraft will act according to the configuration of the Assistant

Software once Fail-Safe is triggered.

 Refer to the LED Indicator Description in the Appendix.

Start & Stop Motor Knowledge

Both Immediately Mode and Intelligent Mode are available in the Assistant Software:

Advanced->Motor->Stop Type.

If necessary, please select the Intelligent Mode in the Assistant Software.

By using the Intelligent Mode, different control mode has different way of stopping motors.

 In Manual Mode, only executing CSC can stop motors.

 In ATTI. Mode or GPS Mode, any one of following four cases will stop motors: a) You don’t push throttle stick after motors start within three seconds; b) Executing CSC; c) Throttle stick under 10%, and after landing 3 seconds. d) The slope angle of multi-rotor is over 70°, and throttle stick under 10%.

For Intelligent Mode

 In ATTI. / GPS Mode, it has landing judgment, which will stop motors.

 Start motors in ATTI. / GPS Mode, you have to execute CSC and then push throttle stick over

10% in 3 seconds, otherwise motors will stop after 3 seconds.

 During normal flight, only pull throttle stick under 10% will not stop motors in any control mode.

 For safety reason, when the slope angle of multi-rotor is over 70° during the flight in ATTI. /

GPS Mode (may be caused by collision, motor and ESC error or propeller broken down), and throttle stick is under 10%, motors will stop automatically.

For Both Intelligent Mode & Immediately Mode

 If you choose the Immediately Mode, you SHOULD NOT pull throttle stick under 10% during flight, because it will stop motors. If you do it accidentally, you should push the throttle stick over

10% in 5s to re-start motors

 When transmitter commands are valid under any control modes, the motors will start or stop immediately when you execute CSC. It has nothing to do with the current throttle stick position.

Please DO NOT executes CSC during flight without a good reason.

 If you choose Intelligent, throttle stick under 10% will trigger landing judgment in any control mode. In this judgment, pitch, roll and yaw controls are denied except throttle, but multi-rotor will still auto level.

 In any control mode, DO NOT pull throttle stick under 10% during normal flight without any reason.

 The two cut off types will only work correctly if the transmitter calibration is correct.

 In failed-safe, CSC is denied by the main controller, motors will hold their state.

Intelligent Orientation Control (IOC) Flight (with GPS module)

Definition of Forward Direction:

Multi

-rotor will fly along this direction when you push the elevator stick.

Graphic Description:

Step 1 Before You Start

Forward direction

Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using IOC, wherever the nose points, the forward direction has nothing to do with nose direction. The red and blue arrows on the transmitter are corresponding to pitch and roll operations in the following diagram.

 In course lock flying, the forward direction is the same as a recorded nose direction.

 All the following requirements are met: the autopilot system is in ATTI. Mode or GPS Mode.

Normal flying Course Lock Flying

 In home lock flying, the forward direction is the same as the direction from home point to multi-rotor.

 All the following requirements are met: 6 or more GPS satellites are found, in GPS Mode, and the aircraft is further than 10m away from the home point.

Normal flying Home Lock Flying

 In POI (POI, Point Of Interest) flying, the roll channel controls the multi rotor circular flight speed around a fixed point, the pitch channel is used for controlling the diameter around the fixed point, the throttle is used to control the height around the fixed point.

 All the following requirements are met: 6 or more GPS satellites are found, in GPS Mode, and the aircraft is further than 5m (and less than 500m) away from the Point of Interest.

Normal flying POI Flying

Step 2 IOC Switch Setting

Refer to the assistant software; click the “Advanced” to find the “IOC”.

Before using the IOC function, you have to choose a 3-position switch on your transmitter as the IOC switch, which is also used for recording the orientation, home position or point of interest in corresponding modes. There are three IOC control mode options, and you should select one in the assistant software.

The above table is for example. The function of the switch position may be reversed since the normal/reversed setting of the switch channel. Toggle the switch and observe the slider position of channel X2 on the assistant software screen, the corresponding area should turn blue.

Step 3 Method of Forward Direction, Home Point & POI Recording

If you use the IOC function, please be aware of the Forward Direction of Course Lock Flying, the home point of

Home Lock Flying, and the Point of Interest of the POI Flying. There are two ways to record the forward direction and the home point: Manually and Automatically. You may choose any one record method.

If the IOC switch is set as the above table; you can do the manual recording according to the following table.

IOC FLYING NOTES

！！！

When Multi-rotor is flying by home lock far away from you and the home point, please DO NOT toggle the IOC switch many times quickly so as to avoid the change of home point without your attention.

 Home lock flying requires that 6 or more GPS satellites are found and the aircraft is further than

10m away from the home point.

 In POI flying, avoid using POI in areas where the GPS signal might be lost or the transmitter

/receiver signal might be lost (such as built up urban areas), to make sure 6 or more GPS satellites are found. And the multi-rotor is required to fly further than 5m (and less than 500m) away from the Point of Interest.

 Continuously spinning will cause a yaw error. In this case, you can stop or slow down the spinning, so as to have better flight performance.

 If the IOC flying requirement is not satisfied, the autopilot system will quit IOC control mode.

Please be aware of the LED indicator, to know the current control mode of the autopilot system.

 Before you do the home lock flight, you have to fly the aircraft out of the 10m range around home point, and then flip the IOC switch to Home Lock position to fly in home lock when all the requirements are met. If you have already toggled the IOC switch to Home Lock position when the aircraft is still in 10m range around home point, and this is the first time you are going to fly in home lock during the current flight, then if all the requirements are met, the main controller will change into home lock automatically when Multi-rotor flies out the 10m range around home point..

 When you are flying in home lock mode, if the aircraft is back into the 10m range around home point, or you switch into ATTI. Mode, or the GPS signal becomes weak, the autopilot system will fly in course lock by the current forward direction automatically. But this forward direction is

NOT the recorded forward direction. If you open the course lock now, it will fly in course lock still by the earlier recorded forward direction.

 We suggest that you should know clearly that, by which lock method you are going to fly, and the locked forward direction or home point, before you switch on IOC mode during the flight.

 Refer to the LED Description in the Appendix for more details.

FailSafe

FailSafe methods include Hover, Go-home, and Altitude Go-home. Choose one as your failsafe method, which will be triggered when the MC loses the control signal in one of the following situations:

1) Signal lost between transmitter and receiver, e.g. multi-rotor is out of the communication range, or transmitter has failed, etc.

2) One or more connections of A, E, T, R, U channels between the MC and receiver is lost. If this happens before take-off, the motors will not start if you raise the throttle stick. If this happens during the flight, the

LED will flash blue to warn you, in addition to the fail-safe method. If Hovering fail-safe method is configured and U channel is disconnected, multi-rotor will auto land.

Also, you can select the Go-Home Switch item to start go-home (Go-home, and Altitude Go-home) by using a TX switch during the flight, when selected during flight the LED will flash purple instead of blue.

The multi-rotor position before takeoff, including reference longitude, reference latitude and reference altitude, is saved as home point by the MC automatically when you raise the throttle stick for the first time AND it has 6 or more GPS satellites acquired for more than 8 seconds ( blinks once or no blinking >8secs)

After taking off, every time the aircraft recorded a home-point successfully the LED will blink Cyan quickly for indicating.

THEREFORE: to use any form of Go-home (including failsafe return home), you must make sure 6 or more GPS satellites are acquired for more than 8 seconds ( blinks once or no blinking >8secs) before take-off, this will assure correct recording of the Home position.

Go-Home Altitude

: Determined by the reference altitude and the FailSafe method chosen. That is, the go-home altitude may be different due to fail-safe method chosen.

The aircraft will remain hovering when the fail-safe starts.

Go-Home Switch ： Before using this function, you have to choose a

2-Position 1 2

2-position switch on your transmitter as the Go-Home switch. Then connect the correct channel of the receiver to the X3 port of the MC.

Tx

You should assign: Position-1 to Start; Position-2 to Standby; or reverse the assignment for Position-1 and Position-2.

Move the Tx switch of the channel X3 and check that the corresponding area Start and Standby turns blue on the assistant software screen. If required adjust the Tx channel end points.


18 |

 Switching from Standby to Start will enable go-home during flight and you will no longer have flight control of the Multi rotor. If the multi-rotor is already in a failsafe condition, then the go-home switch will not work.

 If you switch to Manual Mode or Atti. Mode, (and the multi rotor is not in a fail-safe condition), then the go-home is cancelled and you regain control of the multi copter. Once GPS. Mode is re-selected you can once again use the go-home function.

 Use end-point fine tuning on your transmitter to adjust the X3 channel, to give the correct switch indication in the assistant software.

 The following example shows how to enable Go-home by the Tx Switch. Use position-1 to Start and Position-2 to Standby for example.

Position -1 Position -2 Position -1, if the initial switch position is at Start (Position -1).

Position -2 Position -1, if the initial switch position is at Standby (Position -2).

 The home point of the ground station one key go-home is the same as the point set by user in the ground station software.

 If the home point is not set by the ground station, the home point of the ground station one key go-home function is the point recorded by the MC.

 If the Go-Home Switch cannot be selected in the assistant software, that may be due to the X3 channel been set for remote gain tuning, you should change this if required.

FAQ

Fix the TBE (Toilet Bowl Effect) Problem

When flying in GPS Mode and the compass calibration has been done correctly, should you find the aircraft rotating (Toilet bowl effect), or drifting when hovering. Please check the GPS module mounting orientation and then re-do the compass calibration. Carry out the following procedure to re-mount the GPS module.

In the following diagram (view from the top), the aircraft can appear to be rotating in both clockwise and counter-clockwise direction, please re-mount the GPS module correspondingly.

is the rotating direction of aircraft, is the nose direction of aircraft, is the arrow direction on the GPS module, θ is the offset angle for GPS re-mounting(about 10~30 o )

Attitude Controllable When One Motor Output is Failed

For Hexa-rotor, including Hexa-rotor I, Hexa-rotor V, Hexa-rotor IY and Hexa-rotor Y, aircraft is attitude controllable when one motor output is failed.

The WKM can still control the attitude of the Hexa-rotor for a safe landing when one motor output of the

Hexa-rotor has failed, for example, one motor is stopped or one propeller is broken, etc.

The control mode of WKM should be in Atti. Mode or GPS Mode. The aircraft will rotate, due to an imbalance of torque; however, it can still be controlled by the Transmitter.


26 |

Select Course lock or home lock mode for flying the aircraft into a safe area to land when the aircraft is far away or the attitude can’t be recognized. Even when the multi rotor is rotating, using Course lock or home lock mode will allow you to move the multi rotor in the corresponding Transmitter stick direction.

Flight Restriction in Specified Area Description

Flight Functions are restricted within the radius of 15Km from Tiananmen Square in Beijing, China.

In the restricted area, with GPS/Compass Module and GPS signal is good, you cannot take off the aircraft in any

Control Mode.

In the restricted area, with GPS/Compass Module and GPS signal is bad, you can take off the aircraft, once the

GPS signal becomes good, you can only control the aircraft to land. Manual Mode is free form restriction.

Fly into the restricted area, you can only control the aircraft to land. Manual Mode is free form restriction.

Abnormal Cases in Motor Test

Below are abnormal cases and solutions for Motor Test in the Assistant software

(1) Tested motor does not rotate, there are two situations: a) Connection issues: please check the connections first, such as whether MC and motors are power on, whether connection between MC and ESC is well, whether three cables of ESC are correctly connected to motor. If connections are well, then check whether motors or ESC are breakdown. b) Please increase the Motor Idle Speed in the Advanced page of Assistant software.

(2) Tested motor rotates in wrong direction: please swap over any two wire connections of the motor.

(3) Rotating motor is not the tested motor (e.g. M2 motor rotates when click button”M1”): please ensure the cable of ESC is correct connected to the right port of MC.

Solution for LED yellow and green blinking

LED blinks yellow and green ( ) alternatively means compass errors or interferences:

(1) Long time

(2) Temporary

: in this case compass calibration is required.

: e.g. LED blinks several times when the aircraft flying over some district and then no blinks; or take an calibrated aircraft from outside to inside of house, the may appear inside. In these cases the compass is ok and has no influences to flight. Compass calibration is not required.

When compass data become abnormal (LED blinks yellow and green ) during flying, for safety reasons, the autopilot system will auto change the control mode. However in ATTI. and Manual Mode is free from influence. In any other control mode, the autopilot system will enter into ATTI. Mode automatically (the mode shown on status bar will be “Atti.” if you connect the autopilot to the assistant software). Once the compass data go back to normal, the autopilot system will regain the original control mode.


27 |

Solutions for failed gain value adjustment in the Assistant software

If you fail to adjust the gain value in the Assistant software, please check the follow items to solve the problem.

(1) Make sure the MC has connected and communicated with the Assistant software successfully.

(2)Make sure the Receiver has connected to the MC successfully.

(3)Make sure you have selected the correct Receiver type in the Assistant software, and then you can try to adjust the gain value again.
