Cautions 

When flying, the rotating propellers may cause serious damage and injury. Please fly safe at all times. 

Assembly Cautions 

1. 

2. 

3. 

4. 

Use a bracket to mount the GPS module on the center frame to avoid interference with the power board. 

Ensure the IMU is mounted with the arrow pointing toward the nose of the aircraft. 

If using a receiver, attach it under the bottom board of the center frame with the end of the antenna 

facing downwards and away from obstructions to avoid signal loss. 

Ensure frame arms are mounted correctly. 

a) Motor mounts with CCW marks should be mounted to lhe center frame positions with the following 

marks: Ml, M3 and M5. 

b) Motor mounts with CW marks should be mounted to the center frame pos1tions with the following 

marks: M2, M4, and M6. 

5. Do not remove any glued-in screws. 

6. Screws that already have blue glue can be used once without thread locker. On other occasions, apply 

appropriate thread locker first. 

7. The S900 should be lifted off the ground when testing landing gear or recalibrating servo travel. 

Flight Cautions 

1. ESCs are not water-proof, please do not fly in rain or snow. 

2. Ensure all soft dampers and vibration absorbers are in good condition before every flight. If not, replace 

immediately. Otherwise, the flight performance of your aircraft will be adversely affected. 

3. Ensure all parts are in good condition before each flight. Do not fly with wom or broken parts. 

4. Ensure propellers and motors are inslalled correctly and propellers are unfolded before flying. 

5. Ensure ESC signal connectors and power cable connectors are tight before every flight. 

6. When flying, maintain a sale distance away from people, buildings, high-voltage lines, tall trees, water 

and other hazards. 

7. Use only 68 LiPo batteries for the power supply. 

8. Ensure all output signals from M1 to M6 are in proper working order when using the OJI A2 flight control 

system to avoid damage or injury. 

9. Do not overload the system. 

10. Do not get close to or touch motors or propellers when they are spinning as this can cause serious injury. 

11 . Disconnect the battery and remove the camera during transportation to avoid damage or injury. 

12. We strongly recommend using as many DJI manufactured parts as possible. 

Others 

If you have any problems you cannot resolve, contact your dealer or DJI customer service.

Mounting Frame Arms 

Instructions 

1. Prepare the arms. 

(1) Check all propellers for cracks, then install and screw each propeller cover on tightly. 

(2) Ensure all motors are mounted firmly and rotate freely. 

(3) Mount all arms with red propeller covers to M 1 and M2 to indicate the nose of the 8900. 

(4) Identify the CW and CCW marks on the arms. Mount the arms with the CCW mark to the Mt, M3 and 

M5 positions of the center frame. The arms with the CW mark should be mounted to the M2, M4 and 

M6 positions of the center lrame.

2. Insert each frame arm vertically into the mounting 

area on the center frame. 

3. Line up the screw holes ol the frame arm and 

center frame. 

4. Insert the M4x35 screw from the right of the 

frame arm (the thread is located on the left of the 

screw mount). Tighten each screw correctly. Over 

tightening may lead to connector abrasion.

lock. Check the arm for movement. To store, untwist the knob and lower the frame arm. 

7 Now unscrew 6 screws (M2.5x8 cheese) on the upper plate of the center frame and remove the upper 

plate. Then unscrew the 4 screws (M3x8 self-tapping. found under the center frame) of the round cover 

and remove 11 to ga1n access to the ESC and power cable installation area 

8 Plug each ESC signal cable into the slot near each arm on the center frame.

9. Connect the power cables to the center frame. Each cable must be screwed into a positive(+) or negative(-) 

gold bracket. Each bracket will have two cables of the same color screwed into it. Red cables are positive 

and black cables are negative. 

10. To ensure a reliable connection, rotate the screw until it is both tight and parallel to the connecting 

bracket.

Connecting XT60 Ports on the Center Frame 

The bottom board is a power d1stribution board with three XT60 connectors for battery power. 

Instructions 

1. Connect the PMU power cable to the XT60 connector on top of the bottom board. 

2. Connect the landing gear control board cable to the XT60 connector on the bottom of the bottom board. 

3. Other connectors can supply power for other DJI devices, as required. 

Installing Battery 

Soldering battery connectors 

AS150 spark-proof connectors are used. They must be soldered to your battery power cables. 

1. Remove the original battery connectors. Avoid cutting the power and ground cables at the same time, as 

this can cause a short circuit. We recommend wrapping unsoldered cables with insulating tape to prevent 

accidental connections. 

2. Pass the black ground wire through the black housing. After passing lhe wire through, solder the female 

bullet connector to the ground wire. Wait for the soldered connection to cool, then pull the housing back 

over the bullet connector. 

3 Screw and pass the red power wire through the red housing After passing the w1re through, solder the 

male bullet connector to the power wire. Wrut for the soldered conneclion to cool. and then screw and pull 

the housing back over the bullet connector.

Setting Up the Landing Gear 

Using a 2-position RC transmitter switch, landing gear retraction can be carried out remotely. 

Setting up the transmitter 

Select a 2-position switch (default setting is OK) as the control input for the landing gear. Ensure the 

corresponding receiver port is connected to the "IN" port on control board. For the A2 flight control 

system, connect the flight controller's F1 port to "IN" port on control board. 

,- ( ~ Upper: Toggle the switch to this position to raise the landing gear. 

-,' 

, 

II ~ ~ I Lower: Toggle the switch to this position to lower the landing gear. 

Lt, · If the transmitter switch has a FailSafe function, set the FanSafe value to the [Lower] position. This 

ensures that the landing gear will lower automatically when the receiver enters FailSafe mode. 

• To avoid accidental switch triggering, slide levers or other controls can be used for landing gear 

control. 

Usage procedures 

1. Ensure transmitter and receiver batteries are fully charged. 

2. Toggle the switch to the [Lower] position, and then turn on the transmitter. 

3. Ensure the "R", "L" and "IN" connections are correct. 

4. Ensure the landing gear is in the [Lower] position, then power on the system. If a solid green LED on the 

landing gear control board lights up, everything is normal. If it llaslles green slowly, re-calibrate the system 

according to instructions 1n "Recahbratlng Servo Travel". 

5. Toggle the SWitch to the [Upper] pos~1on ONLY AFTER takeoff. 

6. Toggle the switch to the [Lower] position lor landing.
