Yep, its thick epoxy glue. Its calculated risk since there is no room for a protective box - I can't make any changes or repairs once the epoxy sets.

The "ultimate" power switch:

The power wiring for the lightweight has been givving me all sorts of problems; too bulky, ugly, too stiff, etc. After several failed attempts, I have come up with the ...
