I have a OpenROV V.2.7 (fully assembled) from 2015, which was not used for approximately one year. Now I want to make it going again.
This worked quite well in the beginning, but when I was updating the software and had look on the main tube after approx. 30min, I realised the O-ring on one side came loose despite the black strings were attached with high tension.
Is this a common problem? And do you have any suggestions to fix this problem? Is this caused by the air expanding inside the tube, as it is heated?
I attached some pictures to make my case more clear.
The condensation on the inside of the tube comes from old, maybe humid dessicant pouch which will be replaced.
Thank you for your help!
