Ok I have done the water test, but I have found a few problems with the wiring the main one is that I can only work with only one speed going forward and that is fast, not slow, not medium but fast.

But other than that none of the wires got to hot after doing the test for about 5-10 minutes.
I am thinking of upgrading the speed controller just like Electricalgod has done by puting three ESC in or do you think I can fix the problem with the speed controlleror if not, have you got any good ESC's that you recomend me to use?
