## Maintenance supplies needed - Threadlocker (medium strength)

## Preparation

1. Find a flat surface like a table big enough to fit the DeltaQuad Evo's fuselage.
2. Remove the hatch, as this gives more stability when the fuselage is lying upside down on the table.
3. Take the fuselage of the DeltaQuad Evo out of the flight case.
4. Put the fuselage upside down on the table.  &#x20;

{% hint style="info" %}
The VTOL arm does not need to be removed from the fuselage to change the landing gear leg, which can be done with the VTOL arm installed.
{% endhint %}

## Changing the landing gear leg

1. The landing gear leg is held in place by two screws located at the base of the landing gear. If the landing gear is retracted, manually deploy the landing gear leg by slowly moving it upwards by hand.

3. After removing the screws, move the leg slightly toward the VTOL arm and pull it upwards.&#x20;

4. The landing gear leg has a knee joint that needs to be inserted into the corresponding mounting hole on the VTOL arm.

{% hint style="info" %}
Ensure that the knee joint of the landing gear leg is properly inserted into the mounting hole on the VTOL arm, as this connects to the servo mechanism that moves the leg. If not properly installed, the landing gear leg will not deploy or retract correctly.
{% endhint %}

5. Install the new landing gear leg by connecting the knee joint of the leg with the mounting hole of the VTOL arm.

6. Move the leg into the deployed position. Ensure that the landing gear latch properly connects to the latch opening on the base of the motor mount.

7. Reinsert the two screws into the corresponding holes and tighten them with the Torx tool (T10).

{% hint style="warning" %}
Before attaching the new landing gear leg make sure to use threadlocker on each tip of a screw.

The landing gear leg is now installed. Ensure that it is securely aligned and properly set in place. Double-check that all screws are snug but not overtightened to avoid any damage.&#x20;
