Potentially water inside sci bay aft hull/ring and slightly into aft hull/sci bay joint. Was dried up and non-increasing. Dessicant seemed fully absorbed. No idea when the leak may have occurred. Glider was recovered due to fin aborts. Most ended up being fin could not go hardover starboard due to loosening set screw. It also got stuck there too. Also high power usage was partially/mostly/all tied to SBMB2. It drew 50 mA more than any other tested boards with any persistor. Swapped for ru29's SBMB2. Power so far appears 1 AH/day lower.
