Hi @daweim0,
Ah, its been a while since I’ve thought about this. We discontinued the original Blue ESC in April 2016, and spent about a year and a half afterwards working on a new version, without much success.
The short answer is that potting is not a reliable solution to keeping electronics waterproof, at least the way we had been doing it back then. Even now, we are moving away from potting in general for manufacturability and reliability reasons, which is why we recently released the new WetLink Penetrator.
It’s possible that we may have been able to overcome the issues with enough time and effort, but it was determined not to be worthwhile, given a lack of strong demand and and already solid reliable solution with the Basic ESC. We prioritized other projects.
