# Cautions Whenflying. the rotating 

### propellers may 

### cause serious 

### damage and injury. Please fly safe at all times. 

### Assembly Cautions 1. Use a 

### bracket to mount the GPS 

### module on the 

### centertrame to

### avoid interference with the 

### power board. 2. Ensure the IMU is 

### mounted with the 

### arrow pointing toward the noseof the 

### aircraft. 3. If 

### using a receiver, 

### attach it 

### under the 

### bottom board of the 

### center trame with the 

### end of the 

### antenna 

### lacing downwardsand awayfrom 

### obstructionsto 

### avoid signal loss. 4. Ensure frame arms are 

### mounted 

### correctly. a) 

### Motor mounts with CCW 

### marks 

### should be 

### mounted to the 

### center trame positions with the 

### following marks: M1. M3 and M5. b) Motor 

### mountswith CW 

### marks 

### should be 

### mounted to the 

### center frame 

### positions 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 

### lockerfirst. 7. TheS900 

### should be lifted off the 

### ground when 

### testing landing gear or 

### recalibrating servotravel. 

### Flight 

### Cautions 1. ESOs are not 

### water-proof, 

### please do not fly in rainor snow. 2. 

### Ensure all soft 

### dampers and 

### vbration absorbers are in 

### good condition before 

### every flight. If not, 

### replace immediately. Otherwise,

### theflight

### performanceof 

### your aircraftwill be

### adversely affected. 3. Ensure all parts are in

### good condition before 

### each flight. Do notfly with worn or 

### broken parts. 4. Ensure 

### propellers and motors are 

### installed

### correctly and 

### propellers are 

### unfolded beforeflying. 5. Ensure ESC 

### signal

### connectors and 

### power cable 

### connectors are 

### tight before every flight, 6. When flying. 

### maintain a sate 

### distance away from 

### people, buildings, high-

### voltage lines, tall trees, 

### water and 

### other hazards. 7. Use 

### only 63 LiPo 

### batteries for the

### power supply. S. Ensure all 

### output signals from M1 to M6 are in 

### proper working order

### when using the DJI A2 

### flightcontrol system to avoid 

### damageor injury. 9. Do not 

### overload the system. 10. Do not get close toor touch motors or 

### propellerswhen they are spinning as this can

### causeserious 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.
