I'm new to the RC Hobbie and bought the new E Revo VXL brushless car. A few weeks later I picked up a used E Revo that looks very similar to the VXL so I think this one is only a year old maybe. I need to order parts for the older model but I don't have a manual. I did an internet search and found out about six different models have been made over the years. Can anyone tell me how to figure out what model I have so I can get a parts book?
