# 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

# & •If the transmitter switch has a FailSafe function, set the FailSafe value to the [Lower] position. This ensures that the landing gear will lower automatically when the receiver enters FailSafe mode_ • To avoid accidental switch triggering, slide levers or other controls can be used for landing gear

control. 

### Usage procedures 1. Ensure transmitter and receiver batteries are fully charged. 2. Toggle the switch to the [Lower] position, and then turn on the transmitter. 3. Ensure the "R", "L" and "IN" connections are correct 4. Ensure the landing gear is in the [Lower] position, then power on the system. If a solid green LED on the landing gear control board lights up, everything is normal. If it flashes green slowly, re-calibrate the system according to instructions in "Recalibrating Servo Travel". 5. Toggle the switch to the [Upper] position ONLYAFTER takeoff. 6. Toggle the switch to the [Lower] position for landing.

# ·v· • 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. • If servo power consumption is too high, the LED will light up red. If this lasts more than 4 seconds,

the landing gear will lower and the LED will flash green slowly. Re-calibration is needed before flying.

# 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.

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.

### I 7N gimbal, users should purchase extended landing gear legs (used with Z15-5N 

### I 7N gimbal) to avoid damage and/or failure during the self-test. Referto 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.

Then the gimbal can be mounted as shown below. :\): Package No.34 is for users whose landing gear legs are 300mm. Users whose landing gear legs are 350mm have no need to purchase this part.

### ~\): Refer to original screw tensions if you are unfamiliar with torque measurements. Applying thread locker to the propeller mount first avoids getting thread locker into the holes of the plastic propeller. 

# & Loose screws cannot be securely locked with thread locker.



## Propeller Precautions Torque markers on the screws and propeller covers will give you avisual cue to check whether the propellers are loose. Check the torque markers before every flight.

# X Using the Propeller Holder Instructions 1. Insert the propeller blades into the propeller holder.



## Assembling Motor Vibration Absorbers Spreading Wings S900 User Manual

2. Attach the propeller holder to the frame arm.

A soft damper is part of the vibration absorber. Assemble soft dampers as shown below. Assembly is the same for CCW and CW propellers.



# & •Ensure all soft dampers and vibration absorbers are in good condition before every flight. If not, replace immediately. Otherwise, the flight performance of your aircraft will be adversely affected. • Before installing the soft dampers, put the copper gaskets onto the four mounting holes on the

carbon plate. Then put the soft dampers into the mounting holes. • After tightening the screws, the vibration absorbers may be twisted. If this is the case, hold the

motor with your thumbs under the base plate and fingers on the top carbon plate, and squeeze the plates together to make the vibration absorbers flat and parallel with the plates.

## Remounting the Landing Gear Servo Remounting servos is not recommended as they are pre-installed. 

### Instructions 1. Connectthe left servo cableto the "L" port ofthe landing gearcontrol board. 

### 2. Connectthe right servo cableto the "R" port of the landing gear control board. 

### 3. Press and hold the SET button using a pin then power on. You will see a yellow LED beside the SET button flashing quickly. Wait as servos complete position initialization. 

### 4. Make sure the arm connecting to the servo is parallel to the link as shown in the following diagram. 5. Assemble the left and right servos to the left (between M3, M4) and the right (between M5, M6) parts ofthe landing gear. Power 

### off.

After Installation

3. Keep the whole aircraft off of the ground during calibration, as landing gear will move. 4. Press and hold the SET button using a pin while powering on, then release. An LED will flash yellow quickly. Press the SET button again. Auto calibration will begin and the LED will flash yellow slowly. DO NOT obstruct any moving parts during auto calibration. 5. During calibration, the left landing gear will raise and lower, followed by the right landing gear. 6. After calibration, both the left and right landing gears will be lowered and the LED will displaya solid green light. This indicates that the landing gear is working properly.

### ~ • If the LED is solid yellow after calibration, a problem has occurred. Carry out the instructions in "Remounting the Landing Gear Servo" then try again. • Avoid obstructions during calibration. If the landing gear was obstructed, recalibration will be

required, per the above steps. • If the "R" and "L" servo cables are reversed, travel will not be measured correctly. Fix the

connections and recalibrate the landing gear using the above steps. • Landing gear travel has been pre-calibrated. Mechanical adjustment of the gear travel is not

recommended.
