During a mission climb, the drone suddenly became unstable and began to fall. I attempted to take manual control and switched to Position mode, but the drone did not respond to RC inputs. According to the logs, there were warnings related to attitude failure (roll) and an EKF filter fault, which may indicate a problem with state estimation or sensors. After the crash, I noticed that the RF RC module/chip was no longer attached, which likely caused the loss of manual control signal during the incident.
Hi there!
The main problem seems to be that you have massive vibrations, way beyond the limits of what is considered safe.
Additionally, your motor commands seem to bounce between 0 and the intended value. This could be caused by the vibration, or if you have something else, like for example a idle sim running on the GCS in the background somewhere.
This behaviour could have lead to the motors overheating, and them losing thrust, but this is just a guess for me.
The attitude Failure and EKF filter fault are just a consequence of the crash and should not worry you too much for now.
