Miniature tuperware party ftw.

I would put the holes around the sides though, low down; if you leave the top open but sides and bottom sealed, it will likely fill with water sprayed up by the tires as it goes through puddles.

Lots of small holes wont let in much water so long as its not submerged, though a fully selad box would be better for a fully submerged esc- stick a small cool pack in there and the esc fan will still have cool air to cirulate...
