Spreading Wings S900 User Manual Connecting the main controller to the center frame 1. Connect the flight control system according to your flight control system user manual. 2. Plug in the connector sets to the ESC signal outlet on the center frame. Then plug in the connector set to main controller as shown below. (1) Yellow 4-pin cables are for M1~ M4 connections. The yellow cable should be connected to M1. (2) Brown 4-pin cables are for M5~ M6 connections. The brown cable should be connected to M5.
Spreading Wings S900 User Manual Connecting the main controller and landing gear 1. Connect the left servo (between M3 and M4) cable to the “L” port of the landing gear control board. 2. Connect the right servo (between M5 and M6) cable to the “R” port of the landing gear control board. 3. For the A2 flight control system, connect the F1 port of the main controller to the “IN” port of the landing gear control board. Other flight control systems connect a 2-position channel receiver to the “IN” port.
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 power cable to the XT60 connector on top of the bottom board. 2. Connect the landing gear control board cable to the XT60 connector on the bottom of the bottom board. 3.

Setting Up the Landing Gear Using a 2-position RC transmitter switch, landing gear retraction can be carried out remotely. Setting up the transmitter Select a 2-position switch (default setting is OK) 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, connect the main controller’s F1 port to “IN” port on control board. Upper: Toggle the switch to this position to raise the landing gear.
Spreading Wings S900 User Manual Servo power will shut off 3 seconds after the landing gear has reached its target position. When powering on the system, if the transmitter switch is in the [Upper] position, the LED will flash red quickly as a warning. Toggle the switch to the [Lower] position to continue. If there is an abnormal signal or no signal input into the [IN] port, the LED will slowly flash red. Check receiver and connections for problems.
Mounting the Gimbal Before assembling the gimbal, install the GCU as shown below. Be sure to install on the side as shown below. A DJI Z15-GH4 (HD) gimbal has been used as an example in the following diagrams. Mounting the Gimbal The connectors on gimbal should be removed for better performance, then the gimbal can be mounted to the lower connection points. Users of DJI Z15-5N/7N gimbal, refer to the DJI Z15-5N/7N Gimbal Mounting Notes (P21) for details. 20 © 2014 DJI. All Rights Reserved.
Spreading Wings S900 User Manual Check that the system’s center of gravity is on the line as shown in the diagram below. Due to size restriction for Z15-5N/7N gimbal, users should purchase extended landing skid legs (used with Z15-5N/7N) to avoid damage and/or failure of the self-test. Refer to the Package No.34 of the Part List (P31) for details. Follow the Mounting the Landing Gear (P6) instructions to mount extended landing skid legs. Then, the gimbal can be mounted as shown below. © 2014 DJI.
