Cautions When flying, the rotating propellers may cause serious damage and injury. Please fly safe at all times. Assembly Cautions Cautions 1. Use a bracket to mount the GPS module on the center frame to avoid interference with the power board. 2. Ensure the IMU is mounted with the arrow pointing toward the nose of the aircraft. 3. If using a receiver, attach it under the bottom board of the center frame with the end of the antenna facing downwards and away from obstructions to avoid signal loss. 4.

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 flight 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 (Page 21) 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 the size restriction of the Z15-5N / 7N gimbal, users should purchase extended landing gear legs (used with Z15-5N / 7N gimbal) to avoid damage and/or failure during the self-test. Refer to the Part List Package No.34 (Page 31) for details. Follow the Mounting the Landing Gear (Page 6) instructions to mount extended landing gear legs.
