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.

R/C System

These are example connections.
Please setup Aileron, Elevator,
Throttle, Rudder channels on
your TX first, and choose one 2
or 3 positions switch/channel as
control mode switch, then
connect your receiver to the
right ports on MC.

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.

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)

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.

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.

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.

R/C Receiver

PPM

Pitch

Roll

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!

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.

DO NOT cover the ventilation
holes, keep them unobstructed.
DO NOT mount the IMU upside-
down.
Check the double faced adhesive
tape regularly to ensure that the
IMU is securely positioned.
The IMU module is NOT water-
proof or oil-proof.
