Hi Everyone

I been having the same problems with my drones. The problem is always the same, normal flying, and then, the drone start do go down, not very fast, but fast enought tho damadge it. No matter what I do to try to go the drone UP, keep falling.

After the crush, I turn it on, and all system are normals…

Pls I really need you help

I have change the ESC for another brand, thinking may be was the problem, but the same. This is the 4 or 6 drone with the same behavor. Im looking the logs, but I really cant find the problem…

This flight took almost 15 seconds… then start to fail… In the flight you will see I was moving the drone right to left, that was a deliver movement. Meanwhile I was doing that, the drone start to fall. As soon as the drone start to fall, I change to Stabilize and full throttle (i was in loiter FM), but no change, any way the drone fall.

Before that, i was flying for 30 minutes, doing the same, and no problem, I just change the battery and start over again.

this is the log
