DJI S800 EVO - Manual (Page 13)

1. Assemble the left and right parts respectively, and then fix the screws at the joints with appropriate
thread locker.
2. Connect the left and right parts with connecting rod.
3. For safety reasons, make sure to connect the springs to both 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 receiver to the [IN] port.

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 procedures.
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. Hang 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. 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 solid GREEN on.
Then the landing gear will work normally.
Notes:
(1) If the LED is solid YELLOW on during calibrating, 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.
(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 reversed, the travel will not be measured correctly. Please connect
correctly and recalibrate the landing gear using the above steps.
