I am not following you.
Use the waypoint.
You create a waypoint mission. Create two waypoints.
1. A waypoint to get your aircraft in the air to a set altitude.
2. A waypoint of the destination. When you create this waypoint just set it on the map, then choose the waypoint by pressing on it and then assign it coordinates and it should update its location. Ensure to give it adequate altittude to clear obstacles.
In Flight Hub 2 you could also add the waypoint as an annotation on the map. You can then adjust the coordinates to the precise ones. You would then be able to see this annotation/waypoint in AR (Augmented Reality) on the FPV screen of the M30T. Then you can manually fly to it. You could also create the waypoint mission in Flight Hub 2 similar to above, and then run the mission to have the drone fly to the area on its own. Using Flight Hub 2 is better for me since I like using a PC with a real mouse and keyboard to create missions as opposed to the smaller touch screen of a controller.
