Assembly &Configuration
Step1 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
PMU & Battery
· 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!
· 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.

PPM
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)

Step4 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 360o) 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
360o) 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 (
©2013-2014 DJI Innovations. All Rights Reserved.8 |
) continually, indicating that the compass data is abnormal.
Basic Flying Test
Step1 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.
Use a 3-position switch on the transmitter as mode control switch.
2.
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).
Step2 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
the Control Mode and Stop Motor details.
Setp3 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.

Step4 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.

A2 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.

A3 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:
Forward direction
Step1 Before You Start
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.

Step3 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.
Manually
Control 1:Toggle the switch from Positon-1 to Positon-2, and back to Positon-1 quickly 3 to 5

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.

A4 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.
 Hover
The aircraft will remain hovering when the fail-safe starts.

the correct channel of the receiver to the X3 port of the MC.
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.


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.

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.

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 (
(1) Long time
(2) Temporary
) alternatively means compass errors or interferences:
: 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.
