If you watched the video I linked, you would know that the ESC and receiver is an integrated unit.
When an rc electronic is advertised as "waterproof" it actually means
spalsh-proof. Even if a stand alone piece of electronic is designated as waterproof, a well sealed electronic box is ideal.
Think of your real car. While it will keep you completely dry in the worst rainstorm, we all know it is not a submarine. Therefore, should not be driven into hood high water.
That being said I love playing in wet conditions!
