I pretty sure if you fried your servo its dead. I have heard of people drying it off really quick and then putting the servo in pure water. Something along the lines of minerals in the impure water is what hurts the circuit board not water itself.. But I'm not 100% sure about that lol!

Anyways nothing is working at all? Does it turn on at all? Does your charger say the battery has any juice in it? Worst case scenario is you have to replace your esc, servo, battery and rx..
