Hey, I'm new to this and have been researching for a month. I have come to the conclusion that I want a hpi baja.. Just do not know which 1. I like the fact that I could build the ss and get experience on its workings. Then again, man it would be awsome to get rippin right away too. I think I was told the only real upgrade the 2.0 has is axels? Please correct me if I'm wrong. Thanks ..don
