Cautions
When powered on, the motors and propellers will rotate very quickly and may cause serious
damage and injury. Therefore, please always be aware for your safety.
1. Always y your aircraft a safe distance away from people, animals, high-voltage lines and other
obstacles.
2. Do not get close to or touch the motors or propellers when powered on, as this may cause
serious injury.
3. Make sure there is no short circuit or open circuit.
4. Check that the propellers and the motors are installed correctly and rmly before ight.
5. Check whether all parts of your aircraft are in good condition before ight. Do not y with worn or
broken parts.
6. Use compatible DJI parts.

About
The E310 Multirotor Propulsion System is a tuned propulsion system customized for multi-rotor aircraft
weighing 1 to 2.5 kg. It is efcient, reliable and minimizes vibrations. A revolutionary Electronic Speed
Control (ESC) with a sinusoidal drive replaces the traditional square wave drive, and along with the
new AC permanent magnet synchronous motor, the whole propulsion system is brought into an era
of higher efciency while providing a steady torque output. The integrated sensors and patented
algorithms give the whole system a high level of intelligence and redundancy, and advanced features
include closed loop torque control, real-time system health diagnosis, distinct functional redundancy
for the communication link, and more. Furthermore, the ESC’s rmware can be upgraded by users,
enabling you to enjoy the continual development of the system.
1. In the Box
The E310 is available in two different package congurations. The descriptions below correspond
with the Quad-rotor and Hexa-rotor packages, respectively. Please ensure that you have the correct
quantities of each part before beginning the installation process or using the product.
E.g. “Propeller Pair ×4 or ×5” indicates that there are four pairs of propellers included in the
conguration for Quad-rotors and ve pairs of propellers included in the conguration for Hexa-rotors.
Motor(Clockwise rotation) ×2 or ×3
ESC ×4
or
×6 Outer ESC LED Indicator ×4
In the toolbox: Power hub, Screws (M2.5×6.3), Screws (M3×8.1), Screws (M3×5.5), Wrench for propellers, Foam
double sided adhesive tape, 2.0 mm hexagonal wrench, etc.
Motor (Counter clockwise rotation) ×2 or ×3
or
×6 Updater ×1

2. Gain Value Settings
The new E310 ESC, with a sinusoidal drive replacing the traditional square wave drive, offers
improved acceleration and deceleration performance. Before using, reduce the gain values
according to your ight control system and frame to achieve the same sensitivity as older ESCs (which
use a traditional square wave drive). The table below shows typical gain values when using the E310
with a DJI A2 ight control system and a DJI F450 multirotor ying platform:
Pitch Roll Yaw Pitch Roll Vertical
40% 40% 60% 160% 160% 100%

3. Connecting the ESCs
Tools Required
Tools: Electric soldering iron & soldering tin Use: Soldering each ESC’s power cables to the power hub
1) Check the color tags on the ESC cables to identify the default color of the ESC LED indicator (red
or green). Mount the ESCs onto the appropriate positions of your aircraft according to the LED
color. Note: The LED color can be adjusted in DJI ESC Assistant.
2) Please solder each ESC to the power pads on the power hub as shown in the gure below.
Make sure that the solder is rmly attached on the power pads and that there is no possibility for
a short circuit. The power cable is a coaxial power cable. Do not damage the protector on the
red cable to avoid short circuit.
3) Connect the signal cable to your controller. The orange wire of the signal cable is for the control
signal; the brown wire of the signal cable is for the GND; and the red wire is reserved.
4) Connect the motor to the ESC. Test the motor and make sure the rotation direction of each motor
is correct. If not, switch the position of any two cables that are connecting the motor to the ESC
to change the rotation direction.

To the controller
Power cable
Power hub
The outer power pads are for the GND cables, and the inner power pads are for the
power cables. The red core of the coaxial power cable is positive, and the shielding
layer of the coaxial power cable is negative. Make sure to solder them correctly. Try to
solder the cables rmly to the power hub at the proper length (the wire should be just
long enough to reach the soldering point, without any extra wire bunched up before
the soldering point) and outward facing.
ESC
Make sure there is no short circuit or open circuit.
It is recommended that you solder a power connector onto the power hub.
4. Assembling the Propellers
Silver nut (9450)
Attach the propeller with a silver nut
onto the counter clockwise motor.
Lock: Tighten the propeller by rotating it in this direction.
Unlock: Remove the propeller by rotating it in this direction.

1. Tighten the propellers by following the instructions above.
2. Hold the motor in place and remove the propeller according to the instructions above.
DO NOT use any thread locker on the propeller or motor threads.
5. Mounting the Motors
Mount each motor to a frame arm according to the size of the assembly hole.
4x M3
Thread depth
3mm
19mm
16mm
The screw size is M3. Mount the motors using appropriate screws.
Note the thread depth and the size of the screws. Using screws that are too long or too
large may damage the motor.
6. ESC Ports Description
There are two ports on every ESC. They are Data/ESC Firmware Update Port and Outer ESC
LED Port. Identify the marks on the ESC.
②①
Ensure your ESC rmware matches the motor you will attach it to. Refer to the tag on back
of the ESC to see the default rmware version.
Mount the outer ESC LED indicators according to your needs.
The Data/ESC Firmware Update Port is used to update the ESC rmware.
To do this, visit the ofcial DJI website to download the DJI ESC Assistant.

7. Updating Your ESCs
ESC Updater Computer
Unplug any other serial devices connected to your computer before updating. Then follow the
instructions below:
1) Download the ESC Assistant installer from the DJI website. Run the installer and follow the
prompts to nish the installation.
2) Connect one end of the Updater to the Data/ESC Firmware Update Port. Connect the other end
of the Updater to a computer with a Micro-USB cable. Power on the ESC. DO NOT disconnect
until conguration is nished.
3) Run the ESC Assistant and wait for the ESC to connect. Watch the indicators on the bottom of
the screen. When connected successfully, the Computer Connection status will be solid green
and Data Exchange Indicator will blink blue.
4) Click on the [View] page. In the “ESC” section, check the current rmware version and ensure
the installed rmware is the latest version. If not, click the link and follow the prompts to upgrade.
If the ESC is not automatically recognized by the DJI ESC Assistant (the indicators on the
bottom of the screen show a solid green and an inactive blue), check whether there is more
than one DJI Updater, FTDI USB adapter, or other developer tool (including, but not limited
to, BeagleBone, Raspberry, Arduino, etc.), which may use the FTDI chipset, connected to
the computer. If any of these FTDI devices are connected, simply unplug them and keep
the DJI Updater connected to the computer. Then, restart the DJI ESC Assistant and the
ESC system to form a successful connection.
