The first thing I'd do is check the caps and see if the tops are puffed. If the ESC works, you are probably ok. Most of the time, silicon blows fast when reverse polarity is applied, but polarized electrolytic caps can take a little more time to completely blow. But they could be puffed or weakened and should be replaced. I think the main 3 caps are the only ones that are polarized.
