# About The S900 is designed for professional aerial photography and cinematography. It is user friendly, safe, stabilized and easy to fly while its integrated design makes assembly and configuration simple and fast. Retractable landing gear, vibration dampers, slightly angled arms and a minimalized gimbal mount allow for a clear 360 degree view from the camera. A patented power distribution board, built-in high-speed ESCs and motors with high efficiency propellers ensure dynamic stability and maximized power efficiency. Used with a professional DJI multi-rotor autopilot system, the 8900 can hover and fly reliably making it ideal for photographyand cinematography.

# Cautions When flying, the rotating propellers maycause serious damage and injury. Please fly safe at alltimes.



### Assembly Cautions i. Use abracketto mountthe GPS module onthe centerframe to avoid interferencewith the power board. 2. Ensurethe IMU is mountedwith the arrow pointing toward the nose ofthe aircraft. 3. If using a receiver, attach it under the bottom board of the center frame with the end of the antenna facing downwards and awayfrom obstructionsto avoid signal loss. 4. Ensureframe arms are mounted correctly. a) Motor mounts with CCW marks should be mounted to the center frame positions with the following marks: Mi. M3 and M5. b) Motor mounts with CW marks should be mounted to the center frame positions with the following marks: M2, M4, and M6. 5. Do not remove anyglued-in screws. 6. Screws that already have blue glue can be used once withoutthread locker. On otheroccasions, apply appropriatethread lockerfirst. 7. The S900 should be lifted offthe ground when testing landing gearor recalibrating seNotravel. 

### Flight Cautions i. ESCs are notwater-proof, please do notfly in rain or snow. 2. Ensure all soft dampers and vibration absorbers are in good condition before everyflight. If not, replace immediately. Otherwise, theflight performance ofyouraircraftwill be adverselyaffected. 3. Ensure all parts are in good condition before each flight. Do notflywith worn or broken parts. 4. Ensure propellers and motors are installed correctlyand propellers are unfolded beforeflying. 5. Ensure ESC signal connectors and power cable connectors aretight before everyflight. 6. When flying, maintain a safe distance away from people, buildings, high-voltage lines, tall trees, water and other hazards. 7. Use only6S LiPo batteriesforthe power supply. 8. Ensure all output signalsfrom Mi to M6 are in properworking orderwhen usingthe DJI A2flight control systemto avoid damageor injury. 9. Do notoverload the system. iO. Do not getclose to ortouch motorsor propellerswhen they are spinning as this can cause serious injury. i i. Disconnect the battery and remove the camera during transportation to avoid damage or injury. i2. We strongly recommend using as many DJI manufactured parts as possible.

# Mounting Frame Arms Instructions 1. Prepare the arms. (1) Checkall propellers for cracks, then install and screw each propellercover on tightly. (2) Ensure all motors are mounted firmly and rotate freely. (3) Mount all arms with red propellercovers to M1 and M2 to indicate the nose ofthe 8900. (4) Identify the CW and CCW marks on the arms. Mount the arms with the CCW mark to the M1, M3 and M5 positions of the center frame. The arms with the CW mark should be mounted to the M2, M4 and M6 positions ofthe centerframe.

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 it to gain access to the ESC and power cable installation area. 8. Plug each ESC signal cable into the slot neareach arm on the centerframe.

# Connecting XT60 Ports on the Center Frame The bottom board is a power distribution board with three XT60 connectors for battery power. 

### Instructions 1. Connect the PMU powercable to the XT60 connector on top of the bottom board. 2. Connect the landing gearcontrol board cable to the XT60 connector on the bottom ofthe bottom board. 3. Other connectors can supply powerfor other OJ! 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 the 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 wire through, solder the male bullet connector to the powerwire. Wait for the soldered connection to cool, and then screw and pull the housing backover the bullet connector.

# Setting Up the Landing Gear Using a2-position RC transmitter switch, landing gear retraction can be carried out remotely.

Setting upthe transmitter Select a 2-position switch (default setting is 01<) 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, connectthe flight controller's F1 portto "IN" port on control board.

# Lb, • If the transmitter switch has a FailSafe function, set the FailSafe value to the [Lower] position. This ensures thatthe landing gearwill lower automaticallywhen the receiver enters FailSafe mode. • To avoid accidental switch triggering, slide levers or other controls can be used for landing gear

### 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 itflashes green slowly, re-calibrate the system according to instructions in "Recalibrating ServoTravel". 5.

A soft damper is part of the vibration absorber. Assemble soft dampers as shown below. Assembly is the same for CCW and CW propellers.



# Lt, •Ensure all soft dampers and vibration absorbers are in good condition before every flight. If not, replace immediately. Otherwise, the flight performance ofyour aircraftwill be adversely affected. • Before installing the soft dampers, put the copper gaskets onto the four mounting holes on the

carbon plate. Then putthe soft dampers intothe mounting holes. • After tightening the screws, the vibration absorbers may be twisted. If this is the case, hold the
