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.

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. Hand 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. First the 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 on solid GREEN.

Then the landing gear will work normally.

Notes:

 If the LED is on solid YELLOW when calibrating, then it means that there is something wrong with the

calibration, please re-do the Servo Installation of the Assembly & Connection section, since the servo

arm might be installed with a wrong angle.

 Please avoid any obstruction when calibrating. If the landing gear is blocked from moving, please

recalibrate the landing gear by the above steps.

 If the [R] and [L] servo cables are reversed, the travel will not be measured correctly. Please connect

correctly and recalibrate the landing gear using the above steps.

 If the LED flashes slowly GREEN after power on, please re-calibrate the system using the above steps.

R/C Transmitter (TX) Setting

Select a 2-position switch channel (default setting is OK) on the

TX as the control input of the landing gear, and then make sure

the corresponding port of the receiver is connected to the [IN]

port on the control board.

Retracted： Toggle the switch

to this position to retract the

landing gear (Fig.1)

Lower：Toggle the switch to

this position to lower the

Landing Gear (Fig. 2)

Tips:

 If the switch channel on the TX has fail-safe function, set the fail-safe value to [Lower] position, so that

the landing gear will be in [Lower] status when the receiver enters fail-safe, to land the aircraft safely.

 To avoid false switch triggering, you can use the slide lever or other trim as the landing gear's control

switch.

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 then power on the system. If the green

5. Make sure to toggle the switch to the [Retracted] position only AFTER you takeoff the aircraft.

6. When the aircraft is landing, please toggle the switch to the [Lower] position for a safe landing.

Tips

 The system will turn off the servo power temporarily within 3 seconds after the landing gear has

 If there is an abnormal signal or no signal input into the [IN] port the LED will slowly flash RED. Please

 If the power consumption of the servos is too large when in use, the LED will be on solid RED. If this
