About The Arm Tube
Each of the S900’s arm tubes is riveted to its motor base, which may make disassembly difficult for some users. The E1200 Pro Upgrade Kit for S900 includes an arm tube so that the entire arm system can be completely replaced.

Remounting the Propellers
1) Use 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.

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.

Assembling Motor Vibration Absorbers
Affix the motor vibration dampers. First insert the dampers, then tighten the four screws on motor base mount (M3×12 hexagon). The assembly process is identical for both the lockwise and counter-clockwise propellers.
