## Assembly Cautions 1 2 . 3 . 

### 4. Use a bracket to mount the GPS module on t he center frame to avo id interference w i th t he powe r board . En sure t he IMU is mounted witf-\ the arrow poin ting toward the nose of t he aircraft If using a receiver . attach it under the bottom boa rd of the center frame with the end of the antfmna facing downwards and away from obstructions to avoid signal loss Ensure frarne 

### :-:mns are mounted correclly . a) Motor mounts with CCW marks s h ould b e mounted to the center frame positions with the followin9 marks: M1 . 

### M3 and 

### M5 . b) Motor moun ts with CW marks s h ould be mounted to the center frame positions with the followinn marks: M2 . 

### M4 , and 

### M6. 

### 5. Do not remove any glued-in screws . 6 . Screws that a lready have blue g lue can be used once without thread locker. On other occasions . apply appro p r i ate t hread locker f irst. 

### 7. The S900 shou l d 

### be lifted off 

### th e ground when testing landing gear or recalibrating servo travel. 

## Flight Cautions 1 . ESCs a1e not vvate r-pr oo f , p lease 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 per1ormance of your aircraft will be adversely affected. 3. Ensure all parts arc in good cond ition before eoch flight. Do not 

### fly with worn or broken parts. 4. Ensure prope llers and motors are installed correctly and propelle rs are unfold ed before flying. 5 . Ensure ESC signal connectors and power cable connectors are tight before every f lig ht . 6. When flying, maintain 

### a safe d i stance away from people , b uil dings, h igh-voltage lines, ta ll trees . water and oth er haza rds . 

### 7. Use on ly 

### 6.S LiPo batte ri es for the powe r supply . 8. E:nsure all output signals from M1 to M6 are in proper wo rking o rder when using t he f),JI A2 f lig h t contro l system to avoid damage or 1 n1ury. 9 . Do no l overload the system. 10. 

### Do not get close to or to u ch motors or prope llers when they are spinning as this cnn cause serious injury . 1 1 . f') isconnect the battery and remove the camera duri ng transportation to avoid dumage or injury . 12. We st rongly recommend using as many
