But at $17 its not a big loss if it doesn't work long and if it does, that's a huge win because performance does look good. Maybe buy 2 to be safe at that price.

What online stores are in or near your country?

Your servo motor died because you don't have your radio's end points set correctly and the servo is trying to push the steering further than mechanically possible (probably it) or your car hit something and the force transfered from the wheels to the servo breaking teeth on the gears.
You would hear a crunchy sound though if it was the gears and the heat you are describing sounds like the servo motor is the problem.
