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.

Lower: Toggle the switch to this position to lower the landing gear.

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 ONLY AFTER takeoff.

6. Toggle the switch to the [Lower] position for landing.

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.

A2 flight control system users can use the A2 Assistant to set intelligent gear on the “Advanced” 

page. Refer to the “A2 user manual” for details.

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 Z15-5D MARK III (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.

Remounting the Propellers

Instructions

1. Use two M3x12.3 screws and four washers to remount propellers.

2. Apply thread locker to the thread of the propellers mount first.

3. Affix screws with 3Kg ∙ cm (0.3N ∙ m) torque.

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 a visual cue to check whether the propellers 

are loose. Check the torque markers before every flight.

FAQ

Soldering the ESC

Be sure to solder the thick wires and fine wires correctly when soldering an ESC to the frame arm.

Clockwise (CW) and counter clockwise (CCW) motors have a different arrangement of the colored wires.

Using the Propeller Holder 

Instructions

1. Insert the propeller blades into the propeller holder. 2. Attach the propeller holder to the frame arm.

Assembling Motor Vibration Absorbers 

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. Connect the left servo cable to the “L” port of the landing gear control board.

2. Connect the right servo cable to 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 M7, M8) parts of the 

landing gear. Power off.

Recalibrating Servo Travel 

Instructions

1. Keep your hands away from all moving parts.

2. Ensure the “R”, “L” and “IN” connections are correct.

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 display a 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.
