For the people who don't know how to create a custom Landing Gear, here is the guide:
Build an aircraft
Front Landing Gear:
1. Place the hinge rotator in the desired place
2. Go to XML Modder --> InputController
3. Change the following information:
- Min. (change from -1 to 0)
- Input (Change from VTOL to LandingGear)
- max. (Change from 1 to 1.2)

1. Possibly: InputController ( add new field: disableBaseMesh (Value: true)
2. Exit XML Modder
3. Place a Fuselage Block at the rotating point of the Rotator
4. Rotate Fuselage Block once around the X-axis
5. Adjust the width and height to the size of the aircraft; the same width at both ends
6. Attach one or more Resizable Wheels to the bottom of the Fuselage Block and enlarge or reduce them to the appropriate size
   Main landing gear:
7. Place Hinge rotator
8. Repeat XML modifications
9. This time DEFINITELY disableBaseMesh set to true
10. Rotate Rotator
    (5. Repeat fuselage block placement and wheel placement)
