Hahaha. Yeah that magic smoke was everywhere. It`s already been replaced, and I have a spare...in case I do that again. Now, when I unplug the ESC, I unplug the series connection first. Still can`t believe I did it, but things happen..lol.
The board actually still worked. The burns were from when the protective tape got hot and melted..LOL. I replaced the board anyway, because I don`t trust it 100% now.
