The DJI Complete Frame Arm for S900 includes the frame arm, ESC, motor, props, and intermediate assembly hardware. There are four versions of the prop arm - depending on the stripe color (red or black), prop rotation (CW/CCW), and the ESC LED color (red/green). When replacing, it is crucial to select the exact same version of the prop arm as the original. This version features the red stripped arm, has a red ESC LED, and features counterclockwise (CCW) prop rotation.
The red, counter-clockwise (CCW) Frame Arm for S900 from DJI is an extension positioned between the main airframe the prop motor. When replacing the arm it is vital to use the same joint color and prop rotation designation (CW/CCW) as the original. The prop arms with red joints are the two that face toward the "nose", while those with black joints face the sides and tail.
The Motor Damping Unit for S1000 from DJI consists of rubber dampers that sandwich between the motor and the Motor Mount Carbon Board (Part 10) plus screws to hold the parts together. The dampers help prevent vibration from the motors being transferred to the aircraft via the frame arms, potentially affecting flight performance and making video footage less stable.
The Motor Mount Carbon Board for S1000 from DJI sits between the Motor Damping Unit (Part 8) and the Frame Arm (Part 4, 5, 6, or 7).
The DJI Frame Arm Mounting Steel Shaft for S1000 attaches to the Arm Mounting Bracket (Part 12), enabling the Frame Arm to tilt.
The DJI 4114 Motor with Red Prop Cover for S900 is the motor that drives the propellers. There are two color-coded version and it is crucial to install the correct one when replacing. This model has the red prop cover. If you need the black use instead Part 21.
The DJI ESC with Red LED for S900 mounts on the underside of the prop arm, below the motor. As an electronic speed controller, it regulates how much power gets sent to the motor based on instructions received from the flight control system. With the S1000, there is one ESC per motor/rotorhead. Additionally, there are two versions - a red LED version and a green LED version. It is crucial to replaced the ESC with the same version that was originally there. If you need the green LED version, that part number is Part 24.
Note: Installation requires soldering. Please see the S1000 user manual for installation instructions.
The Premium Propeller Pack for S1000 Octocopter from DJI contains a complete set of eight - four clockwise (CW) and four counter-clockwise (CCW) propellers. Even-numbered motors turn clockwise and odd-numbered motors counter-clockwise. To determine whether to mount a CW or CCW prop, refer to the marking found at the end of each fame arm. It is very important the props are installed correctly to ensure the aircraft will be stable in the air.
