### About The E800 Multirotor Propulsion System is a tuned propulsion system customized for multi-rotor aircraft weighing 3 to 5 kg. It is efficient, reliable and minim izes 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, andadvanced features include closed loop torque control, active braking and energy optimization, realtime 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. The E800 uses new quick-release propellers, which are designed to prevent propellers from flying off during active braking. Together with the energy optimization function of the new ESCs, propulsion performance is more efficie nt than ever before. 

### 1. In the Box Standard Package The E800 is available in two different package configurations. The descriptions below correspond with the Quad-rotor and Hexa-rotor packages, respectively. Plea se ensure that you have the correct quantities of each part before beginning the installation process or using the product. E.g. “1345 Quick-Release Propeller Pair ×4 or ×5” indicates that there are four pairs of propellers included in the configuration for Quad-rotors and five pairs of propellers included in the configuration for Hexa-rotors.

### 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 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.

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 Quick-Release Propellers 1) Unpack the propellers and motors.

The propellers with a CW mark should be mounted to clockwise motors, which have a black propeller 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 outwa rd facing. To the controller ESC signal cable

Power hub ESC Motor 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 E800 with a DJI A2 flight control system and a frame which has a diag onal wheelbase of 580 mm:

2) Align the gap A inside the propeller nut with a fin B on the Pro peller Mount. 3) Press the propeller down onto the mount firmly and, while holding the propeller pressed down,

rotate the propeller in the lock direction until you feel it secure in place. 4) To remove the propeller, press the propeller down firmly and, while holding the propeller pressed

down, rotate the propeller in the unlock direction until it can be removed easily.

Active braking function is enabled by default, and is for use with the standard quickrelease propellers. Using this function with self-tightening propellers may cause the propellers to fly off or other flight problems. Be sure to press the propellers down firmly until they are all the way down before rotating to attach or detach them from the motors. Otherwise the propeller or propeller mounts may be damaged. When attaching a new propeller for the first time, it may not secure in place properly after rotating, because the hole on the propeller nut is blocked. In this case, pull the propeller up to help lock it in position. Then hold the motor in place and try to rotate the propeller. If it can’t be loosened without pressing down, it is locked in place. When storing for an extended period, remove the quick-release propellers to prevent undue wear on the spring locks. Active braking: The motor will provide reverse torque actively to slow down the propeller, and the rotational energy will be recovered.

Lock: Tighten the propeller by rotating it in this direction. Unlock: Remove the propeller by rotating it in this direction. screw and a CW mark on the propeller mount. The propellers without the CW mark should be mounted to counter-clockwise motors, which have a silver propeller screw and a CCW mark on the propeller mount.
