Warnings

When powered on, the motors and propellers will rotate very quickly and may cause serious damage or injury. Always be vigilant and make safety your top priority.

1. Always y your aircraft at a safe distance from people, animals, power lines, and

other obstacles.

2. Do not get close to or touch the motors or propellers when the unit is powered on.

3. Before ying, ensure that the propellers and frame arms are installed correctly and

that the propellers are unfolded.

4. Ensure that all ESC connectors and power cables connectors are securely

attached before every ight.

5. Ensure that all dampers are in good condition before every ight. If they are not,

they may adversely affect flight performance and should be replaced prior to

ight.

6. Check to ensure that all parts of the aircraft are in good condition before ight. Do not y with worn or damaged parts.

7. Only use compatible DJI parts.

About

The E1200 Pro Propulsion Upgrade Kit for S900 is designed for use with DJI S900

multirotor ying platforms. The E1200 Pro features enhanced efciency, security, and

endurance. The Z-Blade 17-inch foldable propellers are made using an advanced carbon-fiber-reinforced polymer, which reduces rotational inertia and enhances rigidity. New, upgraded motors promote efficient heat dissipation to improve

endurance and reliability, even when ying in harsh environments. The Smart ESCs feature a sinusoidal drive, which provides greater efciency and more agile dynamic

response. After upgrading with this kit, your S900 will feature enhanced flight endurance, increased maximum takeoff weight, higher maximum takeoff altitude, and an extended range of environmental working temperatures.

2. Gain Value Settings

The new E1200 Pro ESC, features a sinusoidal drive, which replaces the traditional square wave drive to offer improved performance when accelerating and decelerating. To achieve the same sensitivity as older ESCs, which use a traditional

square wave drive, reduce the gain values according to your ight control system

and frame. The table below shows typical gain values when using the E1200 Pro and

a DJI A2 ight control system on a platform with a takeoff weight of 8 kg:

Basic Attitude

Pitch Roll Yaw Pitch Roll Vertical

90% 90% 80% 130% 130% 100%

The data above is based on ESC rmware v1.5 or above

3. Installation

Tools compatible with the following screws are required: Screws (M4×35), Screws for upper plate (M2.5×8 cheese head), Screws for round cover (M3×8 self-tapping), Screws for power cable bracket (M3×5.5 square drive, hexagon)

1) Remove the original frame arms of the S900

a. If the frame arm is erect, twist the red knob at the arm junction and lower the frame

arm.

Page 4

b. Now unscrew the six screws (M2.5×8 cheese head) on the upper plate of the

center frame and remove the upper plate. Then unscrew the four screws (M3×8 self-tapping) that secure the round cover and remove it.

c. Disconnect each ESC signal cable from the center frame. Then remove each

screw (M3×5.5 square drive, hexagon) on the connecting bracket and unplug the power cables.

d. Unscrew the M4×35 screw and remove the original frame arm.

2) Install the upgrade frame arms

a. Prepare the arms by:

Checking all propellers for cracks and ensuring that all screws are tightened,

Ensuring that all motors are mounted rmly and rotate freely,

Identifying the clockwise and counter-clockwise marks on the propellers. The arms with the counter-clockwise marks will be mounted at positions M1, M3 and M5 of the center frame. The arms with the clockwise marks will be mounted at positions M2, M4 and M6 of the center frame.

b. Insert the frame arm into the mounting slot on the center frame and line up the

screw holes of the frame arm and center frame.

c. Insert the M4×35 screw from the right side of the frame arm, as shown below.

Tighten each screw securely, but avoid over-tightening, which may lead to connector abrasion.

d. Gently lift the frame arm and twist the red knob to lock the arm in place.

e. Plug each ESC signal cable into the slot nearest to each arm on the center frame.

f. Connect the power cables to the center frame. Red cables correspond with the

positive terminals and black cables correspond with the negative terminals. Rotate the bracket screws until they are tight and properly aligned with the connecting brackets, as shown below.

g. Tuck the excess length of the JST 3-pin cable back into the frame arm to avoid any

potential ight complications.

h. Ensure that all ESC signal cables and power cables are correctly connected onto

the center frame.

i. Replace the round cover and tighten the four screws (M3×8 self-tapping), then

replace the upper plate of the center frame and tighten the six screws (M2.5×8 cheese head).

j. Double check all frame arms. Arms M1 and M2 correspond with the nose

direction of the aircraft. Arms M4 and M5 correspond with the tail. When viewed from above, the motors on arms M1, M3 and M5 should rotate counter clockwise and the motors those on arms M2, M4 and M6 should rotate clockwise.

4. Using the DJI ESC Assistant

The DJI ESC Assistant is used to upgrade ESC rmware, congure the propulsion

system, etc.

An Updater is required and is not included with the E1200 Pro. To use the

DJI ESC Assistant, connect the integrated ESC to a

computer through the Updater, as shown below.

Download the ESC Assistant:

http://www.dji.com/product/e1200/download

Frame Arm Updater Computer

Before using the Updater, unplug any other serial devices that are connected to your computer, then follow the instructions below:

1) Download the ESC Assistant from the DJI website. Run the installer and follow the prompts to complete the installation process.

2) Plug the JST 3-pin cable of the frame arm into the data port of the Updater and use a Micro-USB cable to connect the other end of the Updater to a computer. Turn on the ESC system by connecting it to a 6S LiPo battery and do not disconnect the

integrated ESC from the computer until the conguration is complete.

3) Run the ESC Assistant software and wait for the ESC to connect to the program. Watch the indicators on the bottom of the screen. When the ESC has been successfully connected, the “Computer Connection” status will be solid green and the Data Exchange Indicator will blink blue.

Page 8

4) Click on the “View” tab. In the “ESC” section, check the current rmware version

and ensure that the installed firmware up-to-date. If it is not, click the link and follow the prompts to update it.

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.

8. FAQ

Remounting the Propellers

1) Use the two foldable propeller mounting screws (M3×12.5 hexagon), the two propeller cover mounting screws (M3×8), and the four propeller washers to remount the propellers.

2) First apply thread locker to the thread of the propeller mount, then tighten the screws until the propeller blades are securely clamped and can rotate freely.

Loose screws cannot be securely locked in place with thread locker.

Propeller Precautions

Check the markers on the screws and propeller covers before every flight. If the propellers are loose, the markers will provide a visual cue, indicating that the screws should be tightened.

Page 11

Assembling Motor Vibration Absorbers

Afx the motor vibration dampers, as shown below. First insert the dampers, then

tighten the four screws (M3×12 hexagon) on motor base mount. The assembly process is identical for both the clockwise and counter-clockwise propellers.

Ensure that all dampers are in good condition before every ight. If they are not, they may adversely affect ight performance and should be replaced

immediately.
