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 fly 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 firmly before flight.
5. Check whether all parts of your aircraft are in good condition before flight. Do not fly 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 efficient, 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 efficiency 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 firmware can be upgraded by users,
enabling you to enjoy the continual development of the system.
1. In the Box
The E310 comes in two kinds of packages, for Quad and Hexa-rotors. Please check the quantity of
each part in your box before using.
Motor(Clockwise rotation) ×2 or ×3
ESC ×4 or ×6
Motor (Counter clockwise rotation) ×2 or ×3
Outer ESC LED Indicator ×4 or ×6
Propeller Pair ×4 or ×5
USB Connector ×1
Toolbox ×1
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.
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 flight 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 flight control system and a DJI F450 multirotor flying platform:
Basic
Pitch
40%

3. Connecting the ESCs
Tools Required
Tools: Electric soldering iron & soldering tin Use: Soldering each ESC’s power cables to the power hub
© 2014 DJI. All Rights Reserved.
2
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 figure below.
Make sure that the solder is firmly 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.

Motor
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 firmly 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.
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)
Black nut (9450 cw)
Attach the propeller with a silver nut
onto the counter clockwise motor.
Attach the propeller with a black nut onto the
clockwise motor (which has an indent on the screw).
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
16mm
Thread depth
3mm
19mm
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.
①
②
Ensure your ESC firmware matches the motor you will attach it to. Refer to the tag on back
of the ESC to see the default firmware version.
Mount the outer ESC LED indicators according to your needs.
The Data/ESC Firmware Update Port is used to update the ESC firmware.
To do this, visit the official DJI website to download the DJI ESC Assistant.
