Matters Need Attention
For safety reasons, please pay serious attention to all following items:
1 Please disconnect ESCs and battery connector or remove all propellers during firmware upgrade,
configuration and system setup！
2 Do not mount the IMU upside-down.
3 You have to reboot MC and redo the Tx calibration after you change RC system.
4 In Tx Calibration of assistant software:
Throttle: Slide left is craft down, slide right is craft up;
Rudder: Slide left is nose left, slide right is nose right;
Elevator: Slide left is craft back, slide right is craft front;
Aileron: Slide left is craft left, slide right is craft right.
5 GPS/Compass is sensitive to magnetic interference, should be far away from any electronic
devices.
6 Make sure switch on the transmitter first, then power on multi-rotor before takeoff! Power off
multi-rotor first, then switch off the transmitter after landing!
7 Do not fly in GPS Mode when the signal is not good (red light blinks)!
8 If you open the gimbal control in assistant software during the configuration, please note that
there is output from F1 and F2 ports. Now you should not connect these ports to ESCs which is
wired with propellers equipped motors.
9 Do NOT set the failed-safe position of throttle under 10% of endpoint.
10 Throttle stick position should always be higher than 10% from cut-throttle during the flight!
11 Low voltage protections are NOT fun! You should land your multi-rotor ASAP in any level of
protection to prevent your multi-rotor from crash or other harmful consequences!
12 By using Immediately mode to stop motors, 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% in 5 seconds after motors stop, motors will
re-start; Combination Stick Command (CSC) is no need. If you don’t push throttle stick after
motors start in three seconds, motors will stop automatically.
13 By using Intelligent mode to stop motors, motors will start or stop immediately when you
execute CSC. During normal flight, only pull throttle stick under 10% will not stop motors in any
control mode. You have to execute CSC to re-start motors if they stop during the flight.
14 When you set Mixer Type from Octo-rotor to Quad-rotor / Hexa rotor, the gimbal setting will
automatically switch to off for safety, which may lead the gimbal to tilt to one side, please turn
to the Gimbal section for reconfiguration.

15 The receiver is recommended strongly to be installed under the bottom board of center frame,
and the head of antenna is downward without any obstacle. The aircraft will be out of control,
since the wireless signal may be lost by the obstacle.
16 Make sure all connections are correct and attachment contacts are in good condition before
flight.
17 Keep wireless video transmission equipment a distance away from the main controller (>25cm),
to prevent the main controller from antenna interference.

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.
· Check the double faced adhesive tape regularly to ensure that the IMU
is securely positioned.
· DO NOT cover the ventilation holes, keep them unobstructed.
· The IMU module is NOT water-proof or oil-proof.
· Do not mount the IMU upside-down.
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 of Appendix.
· 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)
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.
PMU & Battery
· There is no requirement for PMU
mounting.
· Use our PMU Connecter (red line
depicts in figure) to connect
battery, PMU and ESCs.
· F o r s a fe t y r e as o n, p le as e
disconnect ESCs and battery
connecter during the firmware
upgrade and config u r a t i on
procedure.
· You can choose 2S-6S LiPo
battery.
· Sufficient air flow over the PMU is
highly recommended.
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!

2. Motor Mixer
STEP1: Mixer Type
Set your transmitter into ACROBATIC mode. Then select the right mixer type according to your multi-rotor.
Tips:
We support nine types of multi-rotors. Please refer to “Multi-Rotors Supperted”in “Appendix”:
If you want to use gimbal with an Octo-rotor, you have to use S-Bus or PPM receiver, then you can
use port T and R for gimbal control. Otherwise, there will be no ports on MC for gimbal.
Notices:
Do NOT follow instruction from your multi-rotor manufacturer! Make sure the rotation direction of
each motor is the same as the way assistant software figure shows. If not, switch any of two wire
connetcions of the incorrect motor to change its rotation direction.
Make sure the type of propeller matches the rotation direction of motor.
When you set Mixer Type from Octo-rotor to Quad-rotor / Hexa rotor, the gimbal setting will
automatically switch to off for safety, which may lead the gimbal to tilt to one side, please turn to the
Gimbal section for reconfiguration.
Customize: This segment is reserved only for very special case, such as customized airframe in
non-conventional rotor arrangement. In the event, an airworthy multi-rotor craft with such rotor arrangement
will require customized setting to meet WKM controller algorithm. Please write to our support department or
dealer together with photos of the multi-rotor for assistance.

Tips:
Please refer to “Customize Motor Mixer”section in “Appendix”for how to customize a central
symmetry multi rotor.
If you customize the motor mixer of a quad-rotor or hexa-rotor, F1 and F2 ports can still be used for
gimbal servos control.
STEP2: Motor Idle Speed
Motor Idle Speed is the lowest speed after motor start. Set Motor Idle Speed will affect motor lowest speed
after motor start. There are five levels from LOW speed to HIGH speed, and the default is RECOMMEND.
You can click and drag cursor to the corresponding level, to change Motor Idle Speed.
LOW
RECOMMEND
HIGH
The lower motor idle speed
The higher motor idle speed
Set Motor Idle Speed as LOW, the motor idle speed will be lowest.
Set Motor Idle Speed as HIGH, the motor idle speed will be highest.
RECOMMEND is the advised level.
You can reset the Motor Idle Speed according to the real situation.
Notices:
For user whose aircraft takes off at lowest throttles position, please set the idle speed at a low level.
For common users, please set Motor Idle Speed to RECOMMEND or above, since setting idle
speed too low may affect motor(s) spool up.
Tips:
The output pulse width for every grade of Motor Idle Speed is as followed
LOW

3. Tx Monitor
Notices:
Make sure you have removed all propellers before this step!
STEP1: Receiver Type
Choose the type of your receiver. If you use S-Bus receiver, please choose S-Bus compatible option: D-Bus.
If PPM receiver is used, please choose PPM. Otherwise choose Tradition.
Notices:
Please reboot MC and redo the calibration after you change the setup of your transmitter or change your
receiver!
Tips:
If you use S-Bus/ PPM receiver, the communication of A, E, T, R, U, X2
and X3 channels are all through the D-Bus/PPM channel. Right figure
shows the connection of default transmitter channels and MC channels
in S-Bus/ PPM receiver (Only first 8 channels of S-Bus receiver are
used at the moment). Then the original T and R channels are for Gimbal
servo control.

STEP2: Cut Off Type
Please read the introductions of start and stop motor in this step first, and then choose a cut off type.
1 Start Motor: When using WKM, 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:
2 Stop Motor: We provide two options to stop motors: Immediately, Intelligent.
Immediately Mode: By using this 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% in 5 seconds after motors stop, motors
will re-start, CSC is no need. If you don’t push throttle stick after motors start in three seconds,
motors will stop automatically.
Intelligent Mode: By using this mode, different control mode has different way of stopping
motors. In Manual Mode, only executing CSC can stop motors. In Atti. or GPS Atti. Mode,
any one of following four cases will stop motors:
a) You don’t push throttle stick after motors start in 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%.
Tips (Intelligent Mode):
1 You have to execute CSC to start motors. Push throttle stick only will not start motors.
2 In Atti. / GPS Atti. Mode, it has landing judgment, which will stop motors.
3 Start motors in Atti. / GPS Atti. Mode, you have to execute CSC and then push throttle stick over
10% in 3 seconds, otherwise motors will stop after 3 seconds.
4 During normal flight, only pull throttle stick under 10% will not stop motors in any control mode.
5 For safety reason, when the slope angle of multi-rotor is over 70°during the flight in Atti. / GPS Atti.
Mode (may be caused by collision, motor and ESC error or propeller broken down), and throttle
stick is under 10%, motors will stop automatically.
6 You can stop motors by executing CSC in any control mode.
Notices:
1. All these two cut off types will work properly only if Tx calibration is correct.

©2012 DJI Innovations. All Rights Reserved. 19 |
2. When Tx commands are valid under any control modes, motors will start or stop immediately when
you execute CSC. It has nothing to do with current throttle stick position. Please DO NOT executes
CSC during flight without any reason.
3. If you choose Immediately mode, you should not pull throttle stick under 10% during flight,
because that will stop motors. If you do it accidentally, you should push the throttle stick
over 10% in 5 seconds to re-start motors.
4. If you choose Intelligent mode, 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.
5. In any control mode, DO NOT pull throttle stick under 10% during normal flight without any reason.
6. In any auto action caused by failed-safe or low voltage protection （e.g. auto Go Home）， any
commands applied to start or stop motors are denied by MC, motors will hold state.
STEP3: Command Sticks Calibration
Slides Moving Definition：
T
: Slide left is craft down, slide right is craft up;
R
: Slide left is nose left, slide right is nose right;
E
: Slide left is craft back, slide right is craft front;
A
: Slide left is craft left, slide right is craft right.
STEP1: Set endpoints of all channels to default values (100%) and set all trims and sub-trims of sticks
to 0 on your transmitter first. Keep all curves’settings as default since the end-point of transmitter
sticks will be recorded here.
STEP2: Click START button, and move all of the sticks throughout
their complete range several times.
STEP3: After that, click FINISH button when you finished above procedures.
STEP4: If the moving direction of the slide is opposite to the Slides Moving Definition, click the reverse
button REV/NORM beside.
Notices:
1. All slides should become when all the sticks are in the middle positions. If slides cannot go back
to center points (become ), just click FINISH, then slides will be at center automatically. If still not,
please reboot MC, and do not apply Tx command during the reboot.
2. CSC may not start motors If trims and sub-trims of sticks are not 0!
STEP4: Sticks Monitor

This step is optional. X2 and X3 is for remote gain tuning; X3 is also for gimbal pitch control. Setup the
channel on your RC correctly.
STEP5: Control Mode Switch
Whichever 2 or 3 positions switch on your transmitter you have selected to use as control mode switch, wire
the right channel of receiver to U port of MC. At each switch position, use end-point fine tuning on your
transmitter, move the slider of channel U to GPS (GPS Atti Mode), A (Atti. Mode), M (Manual Mode) to turn
the corresponding area blue respectively as showed in the figure of last page.
Tips:
To move the slider is to adjust end-points of the channel selected.
For 3-position switch, you should assign:
Position-1 to Manual Mode; Position-2 to Atti.
Mode; Position-3 to GPS Atti. Mode; or reverse
the assignment for Position-1 and Position-3.
For 2-positions switch, you can assign any two of these three control modes as you like.
Move the slider to the range which reads Fail-Safe Mode to turn the area blue, set Fail-Safe output of
receiver to input port-U. If you switch off your transmitter now, the U channel slide should move to Fail-Safe
Mode and turn the corresponding area to blue. Otherwise please reset the fail-safe. Please refer to your RC
manual for the details of fail-safe setup.
Notices:
1. Do NOT set the fail-safe position of throttle under 10% endpoint.
2. MC would not execute Fail-Safe protection if you don’t set it properly. You can verify the Fail-Safe
settings by shutting down your transmitter, and then you can use the following methods to check
whether MC is already in Fail-Safe mode.
Check theAssistant Software status bar at the bottom side of the software
interface. Control mode will change to Fail-Safe.
Check the LED indicator. Read the appendix in this manual for details. LED will give blue
blinking if in fail-safe mode.
