RE: Which nitro to get?
If your going to race it on a track, the best stock cars to go with would be the RC10GT or the XXX-nt.
If you want something for bashing, id go with the Traxxas Nitro Ruslter OR Traxxas Nitro Sport.
They are both basically the same Stadium truck, but the Rustler has a much more powerful engine and more people use them.
