Default can water fry a motor?

was running my car on driveway and it slid into a snowbank...
completely covered in snow....
few moments later, car stops and smoke pours out.

ok...
battery is hott and smells real bad.....

throw that batt into the snow so it doesnt catch on fire and pop a new batt in.
still no go... but wheels will turn right/left..

what should i do first?

yea water will not hurt the motor...although the esc/rx yes.....could be either or.....you can actually put a motor in water to clean it and it will run under water......esc sounds like it might be it.although once i ran my xxx4 into a crick..pulled it out right away and same problem is you...no throttle but i had steering...burnt out that whatever it is that runs the throttle in it....esc was ok...
my solution to tell you...try another rx and see if it will work...if thats not the problem its definately the esc...

hope this helps

Yes, if the ESC was shot it would still steer.

Unplug the ESC from the receiver and plug the steering servo into where you just removed the ESC. If the wheels turn when using the throttle/brake control on the Transmitter then your receiver is good.

Sometimes letting a ESC dry will let it work again. But if you saw smoke it may be too late.

Yes, you fried the mosfets. If you can replace them , the esc might work again. Take care though when handling mosfet semiconductors they're finnicky (static elctricity build up on your body, or anything else that touches them kills them).

Motors are fine in water (except sensored brushless).
Receivers usually just require drying out before they'll work again, although a lot of water in a receiver can make all the dust and muck stick together to make a gunge that needs to be flushed out.

ESC's are the main problem with water, they all go bang, and I only know of a couple that I would trust to work properly in water.

Trust me, we know a lot about racing in the UK in the wet

And also frost;

Yes, you let the magic smoke out from electronics. time for a new esc. You're lucky you didn't burn the receiver too. Try wrapping them in a balloon next time.

Balloons are OK for very short periods, but any moisture in the air trapped in the balloon can make the receiver appear to 'sweat', which can still effect the electronics.
