As long as you protect your electronics from the water, you should be fine. Most cars today already provide a reciever cover, but if not, HPI makes them, they just slide over the reciever and protect it from any water or mud. Servos should be fine, they have O-Rings sealing them from water. And as long as your air filter doesnt get soaked in water, your engine should run fine too, propably better than normal because of the humidity.
