Regarding your message about parts for your second hand Vaterra... First off, sorry for the delay. Secondly, the stock parts that come on the car are quite good and all water proof. You can download the manual for the car off Vaterra's site. In the manual you can look up exactly what everything is in the car with part numbers. If you then Google search the part numbers for the parts you need you should be brought to sites that carry them and upgrades. That way you can compare and contrast parts with what came stock...
