Package Items

Main Controller (MC)

The Main Controller (MC) is the brain of the system, it communicates with the IMU, GPS/Compass，ESC and

RC transmitter to carry out autopilot functionality. The Main Controller provides USB interface to configure

MC and update firmware from a PC (System requirement: Windows XP SP3 or 7)

GPS & Compass

The GPS/Compass module is for sensing

the position and direction.

LED Indicator

The LED indicates different states of

system.

IMU

The Inertial Measurement Unit

(IMU) consists of one 3-axis

accelerometer, one 3-axis

gyroscope and a barometer. It

is for sensing the attitude.

USB Cable

This cable is used

to configure MC and update firmware.

3-PIN Servo Cable

Cables used to connect the

Main Controller to the RC receiver.

GPS Bracket

Because the

GPS/Compas-

s is sensitive

to magnetic

interference,

you should

use this

bracket to

mount the

GPS module.

Power Management Unit (PMU)

Specially designed for WKM to solve the high power

consumption problem of power support system. It

contains two power outputs for entire WKM system

and receiver separately, a battery voltage monitor, and two CAN-Bus interfaces.

Power Connection Adapter

For connections among Battery, ESCs and

PMU.

Warranty Information Card

It recommends the necessary conditions for using WKM

system and related safety issues. Please fill out the

customer & multi rotor information card and return to DJI

to register your product warranty.

Matters Need Attention

For safety reasons, please pay serious attention to all following items:

1. Please disconnect ESCs and Power Connection Adapter or remove all propellers during 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 receiver.

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. In Atti and GPS Atti mode, throttle stick center position is for 0m/s on the vertical direction. If you pull the stick to the
