RTL not landing drone

Hi. I have been experiencing an issue using RTL. It returns the drone to its takeoff coordinates but does not land. Just sits at the RTL altitude forever. I looked at the params and set land delay to zero, but no change. Is there any other param that needs to be changed?

Using PX4 1.13.3 and QGC 4.1.7


Can you share a log file?

I fixed this problem by changing some parameters. Now there is another issue. When the drone comes down from an RTL command, it falls very fast, too fast to land without damage, so I have to take over in Position mode to get it on the ground safely. How can I change the vertical landing speed to something a lot slower?


Hi, the lowest descending speed you can set is 0.6 m/s in safety page in qgroundcontrol
