# QGC (QGroundControl) and Arcsky Control

QGroundControl is the free mission planning software installed in all Herelink controllers by default. All Herelink controllers that come with the X55 should have QGC installed and ready to go. Since August 2024, we have been releasing the Herelink with our own customized version of QGroundControl, called “Arcsky Control”. This is a simplified version of QGC, which has less available options and hides much of the QGC functionality that is not needed for operation of the X55.

QGC is also available for download as a desktop application. The features and appearance should be essentially the same as that in the Herelink QGC and Arcsky Control apps.

To learn more details about QGC and Arcsky Control, please watch our video (Arcsky Control Overview) which can be found on our [YouTube channel](https://www.youtube.com/channel/UCZDbb2CPD2h8zeACoe564NQ).
{% endhint %}

Some basic information about QGC is presented below. 

This is the Fly View that will be seen upon boot-up of the application. Refer to our video for an in-depth explanation and overview about what each feature is, and what it’s used for. For now, the basic labels are given on the screenshots below.

## Planning Mission Flights

The Plan view is where you will plan, load, save and modify your mission.

At a high level, the steps to create a mission are:

* Set Home Location. This should be the approximate takeoff location and the start point of your mission.

{% hint style="info" %}
This is only the planned home position and you should place it where you plan to take off the X55. It has no actual impact on flying the mission. The actual home position of the X55 is set by the X55 itself when arming.
{% endhint %}

* Use the plan tools to add waypoints, patterns or load existing mission files.
* Waypoint settings such as airspeed/altitude can be changed inside the mission command list>command editor
* Add mission end commands such as RTL
* Upload the mission to the X55
* Go to the Fly view to execute the mission
