Waterproof Brushless ESC? Only MGM Compro?

[Kajman]

Boxes do not let esc cool down really, but it is interesting idea, can you give me some names how to look for it on ebay or any shops with good ones? Maybe I'll try, it will be colder now, so it might work.
Mtroniks is on my mind sometimes just as wet weather esc, it is only 80Ampers and only 4S, which is already a problem... I talked to boss of MGM on Friday, he said that their ESC are rather splash proof :( When you start digging esc market for MT it apears, that it is quite poor...
