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.

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.
