Hints and TipsImportant
Warning
When powered on, the motors and propellers will rotate
very quickly and can cause serious damage or injuries
if used improperly. Always maintain caution and make
safety your top priority.
The E7000 generates powerful thrust. Be sure to operate
it with caution to avoid potential safety risks. DO NOT
use the E7000 if you are not an experienced user or you
are under the age of 18.

1. The maximum allowable voltage of the E7000 is 52.2 V.
Operate with care.
2. Always fly your aircraft in areas free of people, animals,
power lines, and other obstacles.
3. DO NOT approach or touch the motors or propellers when
the unit is powered on.
4. Before takeoff, ensure that the propellers and motors are
installed correctly and the propellers are unfolded.
5. Ensure that all parts of the aircraft are in good condition. DO NOT
y with worn or damaged parts.
6. Check the connection of the 3-phase cable between the ESC
EN
and motor before each ight. Ensure that the insulating tape
is rmly attached and replace whenever required.
7. Ensure that all parts are firmly in place and all screws are
tight before each ight.
8. Only use compatible, authorized DJI parts.
Introduction
The E7000 Tuned Propulsion System is designed for multirotor
aircraft with a payload of 6 to 8 kg/rotor. The system can be
washed, making it ideal for industrial applications and aerial
imaging in demanding environments, especially agriculture. The
overall solution of a modular single rotor enhances convenience
for assembly and conguration. A 40mm diameter carbon ber
tube is included in the package, while providing a wide range of
tube length to choose from.
The M12 motor is equipped with a weatherproof sealant for the
bearing system and a coating for the motor's stator, preventing
rust and corrosion. Reinforced blades and a perfected
aerodynamic design minimize rotational inertia on the foldable
33-inch Z-Blade propellers to equip large platforms with sharp
response.
The 12100 ESC uses FOC (Field-Oriented Control) algorithms
to allow for more motor responsiveness and precision control.
Additional protection functions extend the life of the ESC. When
used with the DJI N3, A3, N3-AG or A3-AG ight controllers, the
ESC data cable handles communication with the ight controller
and also acts as a backup throttle signal transmission cable for
increased reliability and a safer ight.

2. Flight Controller Settings
The E7000 ESC features a DJI optimized FOC algorithm to
offer improved performance during rotor acceleration and
deceleration. The gain values and power bandwidth must be
adjusted according to your ight control system and airframe.
The table below shows typical parameters when using the
E7000 with a DJI A3 ight control system, a quad-rotor frame
with a diagonal distance of 1200 mm, and at a takeoff weight of
28 kg:

4. Installation and Connection
Use a suitable airframe that can withstand the large
thrust delivered by the E7000 Propulsion System.
The powertrain includes a 40mm diameter carbon ber tube.
Mount the powertrain to an appropriate connector only.
Identify the clockwise and counter-clockwise marks
on the propellers and mount the powertrains onto the
corresponding positions of the airframe.
When connecting cables to the frame’s power system, be
sure to select plugs and wires whose current is sufciently
rated the entire system.
1) Mount the powertrain onto the corresponding position of the
airframe. Rotate to ensure that the propeller is oriented upright,
then x it rmly.
2) Solder the red VCC cable and black GND cable of each
powertrain to the frame’s power system. Make sure that the solder
points are strong and that there is no chance for a short circuit.
3) Connect the signal cable to your ight controller. The signal cable’s
red wire transmits the control signal; the black wire is for ground.
4) When using the powertrain together with the DJI N3, A3,
N3-AG or A3-AG flight controller, connect the data cable
to the iESC port on the flight controller via the smart ESC
communication cable for real-time communication with the

flight controller and redundant throttle signal transmission.
Arrange the cable properly if not used, so that it will not
interfere with other on-board devices.
5. Using DJI Assistant 2
The DJI ASSISTANTTM 2 is used to update the ESC rmware.※
Be sure to remove the propellers before using DJI Assistant 2.
Powertrain Updater Computer
Before using the Updater, unplug any other serial devices that are
connected to your computer, then follow the instructions below:
1) Download and install DJI Assistant 2 from the official DJI
website. (http://www.dji.com/e7000/info#downloads)
2) Connect the Updater to the powertrain with the data cable
and to your computer with a Micro USB cable.
3) Connect a 12S LiPo battery to the powertrain to supply power
to the system. Do not disconnect the powertrain from the
computer or power supply until the conguration is complete.
4) Launch DJI Assistant 2. When a connection is established,
the software will display the connected devices.
5) Click under “Connected Devices” to enter the firmware
update page. Check the current rmware version and ensure
the installed rmware is up to date. If not, login with your DJI
account and click the Upgrade button.
If your ESC is not recognized by DJI Assistant 2 (no
connected devices):
Check if there is more than one FTDI device connected
such as another DJI Updater, an FTDI USB adapter or
development board (e.g. a BeagleBone, Raspberry or
Arduino board). Unplug the other FTDI devices, restart
the ESC and DJI Assistant 2, and try again.
Re-connect the ESC and the power supply in the following
order: Connect the ESC to your computer, connect the
power supply to the ESC, and then launch DJI Assistant 2.
When using the ESC together with the DJI N3 or A3 ight controller,
※
connect the data cable to the iESC port on the ight controller via
the smart ESC communication cable to update all the connected
ESCs’ rmware together in the ight controller page of DJI Assistant
2: Connect the ight controller to DJI Assistant 2 -> ight controller
icon -> Firmware Update -> ESC Firmware List.
