We have some issues with our BlueROV2. We use the ROV with the Heavy configuration since May 2018 without any problems. Last month we faced some problems with the built-in IMU of the Pixhawk. Therefore, we decided to replace the Pixhawk. The vehicle operate fine in the Manual mode. However, if we switch on the Stabilize mode, the ROV starts struggling and then flipped bottom up. After switching back to Manual Mode, everything is all right. The Firmware is the latest Stable version. I attached the current parameter setting, the log-file. I also tried to upload a short video, but the forum does not allow mp4 files.
Any help and suggestions are highly appreciated.
