You could always just get a traxxas [link=http://rc-car-truck.com/waterproof-rc-car/]Waterproof Car or Truck[/link]. You can get their servos by themselves too.

RE: how do you waterproof your electronics?
 

I got a waterproof Traxxas srevo and I will attest that it does work. I just had to put the other cheap standard servo out of it's misery tonite, it kept moving back and forth without any inputs from the Tx. My Traxxsas servodid it's job well. I could not afford two at the time but now I don't really have a choice. They are $32.00 at my LHS and I aint gone take another chance on a cheap standard srevo.....I had just bought the cheapservo days before I bought the Traxas and it is already fried.....due to a mishap that resulted in a moderate amount of water in my radio box (long story.)

Yeah. They are expensive but worth the money because of the support. You can send like up to 3 dead traxxas servos into Traxxas in exchange for new ones for $20 shipped.
