My LHS supports all but the XTM, which happens to be the frontrunner for me right now. I like the HPI Firestorm, but everyone has one and I'm thinking I want something other than what everybody else has. These trucks are laid out so simple compared to 4WD trucks, and it seems like they are all pretty similar in build quality. I just want to know about durability and performance. What are the stock top speeds for the Firestorm and Reaction according to the popular RC mags radar tests?
