I hope some can check my logfile and help me find out the problem for the height loss. The setup is a heavy drone:
- Drone with 12 motors
- 7,5kg payload
- Total weight with batteries 22kg
The problem does happen at different times, the drone slowly looses height, sometimes it recovers before touching ground, sometimes it does not. We testes the payload on a rope, as soon as the payload lands on the ground, the drone recovers. Without the payload it flies fine with the full battery charge for 80min.
We checked the following parts as a source of error:
- Motors, only heated up to 35°
- ESC, also only heated up to around 30°
- The batteries did also not over discharge
So a problem could be some settings, we missed, because it is a heavy drone. Maybe someone can check the logs and our settings?
thanks for any help!
