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 M5, M6) 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.
