RE: Help me
Well in rc car world we take a hairdryer to it that does it most the time. If you do get it to work or replace the board there is a trick that we use in electronics to help with these things. If you look on the internet or sometimes in a hobby shop, there is a Liquid rubber that you can use to dip your electronics in. Most guys use it for SERVOs It does work it is just like a epoxy dipped CB. the rubber doesnt corode like water and after all is dry you could swim with the tank if you wanted to. I know a few at the hobby shop that used it in ther SUBMARINES. There is also a Dip you use for TOOLS. That comfort grip in the handle of a pair of pliers or a hammer. same thing for water protection.
If all else stay away from water!! Tanks dont move that fast that you caint avoid a puddle. [8D]
