I have a question regarding what does the attached menu option in the screen capture do. I had an issue while using the ground station app: i set it up to certain waipoints and the last waypoint was 20m. The return to home hight was also 20m but for some reason it allmost hit a tree which was not more than 10m i think! Does this have something to do with my starting home point which was 5m aprox. higher than the tree location or not? I would have liked the minium hight for return to home to be dinamic and always 20m or more than the drones current location not to the starting point!
