# Mount Landing Gear
By using a 2

- position switch of R/C transmitter, you can control the landing gear to retract remotely. 

# 1 Assembly & Connection The part with the control board at tached is defined as left, and the other part is right. Make sure to make a distinction between the left and the right servos.



### step1: Servo Installation 

### (If the servos have already been installed, please skip this step.) 1. ( S hown in the Fig) Define and mark the two HS

- 7954SH servos from Hitec as left servo and right servo. 2. Connect the left servo to the [L] port on the control board, and the right servo to the [R] port. 3. Keep pressing the SET button with aid of a small tool, and then power on. You will see the yell ow LED
beside SET button flashes quickly, and then wait until the servos have finished their position initialization. 4. Make sure the servo arm is parallel to the servo’s center line. 5. Power off, assemble the left and right servos to the left and the right pa rts of the landing gear. Tips: If you use your own servos, it is recommended to use the dedicated programmer from Hitec to enlarge the servo travel from 120° to 150°, and then install servos by the above steps. Servos from DJI have been enlarged
servo trav el. 

### step2: Mechanical Assembly1. Assemble the left and right parts respectively, and then fix the screws at the joints with appropriate

thread lock er . 2. Connect the left and right parts with connecting rod. 3. For safety reasons, make sure to connect the springs to bo th parts. 

### step3: Electrical Connections 1. Plug the cables from the servos into the correct ports on the control board. Make sure the right servo is
connected to the [R] port, and the left servo to the [L] port. 2. Connect the required 2

- position switch of R/C receiv er to the [IN] port.


# 2 Travel Calibration
If the Landing Gear you got has been installed with the servos, please skip this step. Otherwise, calibrate the system using the following procedure s . 1. For safety reasons, please keep your hands away from any link mechanism to avoid injury. 2. Make sure the [R] , [L] and [IN] connections are correct and firmly connected. 3. Han g the Landing Gear in the air during calibration, as the landing gear will move. 4. Keep pressing the SET button using a small tool and power on. You can see the LED flashes YELLOW quickly, and then press the SET button once again. The system begins auto calibration with the indication of the LED flashing YELLOW slowly. DO NOT obstruct any moving part during auto calibration. 5. T he left

- part is calibrated , the left link mechanism first moves up then moves down automatically. Then the right

- part is calibrated, the right link mechanism first moves up then moves down automatically. 6. After calibration, both left and right parts are in the [Lower] position, and the LED is solid GREEN on . Then the landing gear will work normally. Notes: (1) If the LED is solid YELLOW on during calibrating, i t means that there is something wrong with the calibration, please re

- do the Servo Installation of the Assembly & Connection sec tion, since the servo arm might be installed with a wrong angle. (2) Please avoid any obstruction during calibrating. If the landing gear is blocked from moving, please recalibrate the landing gear by the above steps. (3) If the [R] and [L] servo cables are revers ed, the travel will not be measured correctly. Please connect correctly and recalibrate the landing gear using the above steps.

# 3 Transmitter Setting

Select a 2

- position switch (default setting is OK) of Transmitter as the control input of the landing gear, and then make sure the corresponding port of receiver is
connected to the [IN] port on control board. Fig. 1

Fig. 2



# 4 Usage The landing gear can be used by following the steps below after assembly & connection. 1. Make sure the transmitter & receiver batteries are fully charged. 2. Toggle the switch to the [ Lower] position, and then turn on the transmitter. 3. Make sure the [R] , [L] and [IN] connections are correct and firmly connected. 4. Make sure the Landing Gear is at the [ Lower] position , and the n power on the system. If the green LED is
solid on , then this is a normal start. If the LED flash es GREEN slowly , please re

- calibrate the system according to the procedure of Travel Calibration

. 5. Make sure to toggle the switch to the [ Retracted] position O NLY AFTER you takeoff the aircraft. 6. When the aircraft is landing, please toggle the switch to the [Lower ] position for a safe landing. Retracted : Toggle the switch to this position to retract the l anding gear (Fig.1)
Lower : Toggle the switch to this position to lower the l anding g ear (Fig. 2) Tips: (1) If the sw itch of Transmitter has F ail S afe function, set the F ail S afe value to the [Lower] position, so that the landing gear will be in [Lower] st atus when the receiver enters F ail S afe mode, to land the aircraft safely. (2) To avoid false switch triggering, you can use the slide lever or other trim as the landing gear’s
control switch.Tips

(1) The system will turn off the servo power temporarily within 3 seconds after the landing gear has reached the target position. (2) When powering on the system, if the Transmitter switch is at the [ Retracted] position, which is the unsafe signal for the landing gear, the LED will quickly flash RED. T oggle the switch to the [ Lower] position. (3) If there is an abnormal signal or no signal input into the [IN] port the LED will slowly flash RED. Please
check the receiver and the connections. (4) If the power consumption of servos is too large during us age , the LED will be solid RED on . If this status lasts more than 4 second s, the landing gear will lower and the LED will flash GREEN slowly. Please

re - calibrate the system.
