i was actually going to buy a radar gun at radio shack ($129 new)just to see how fast my cars are. I have a traxxas jato and this is supposed to be faster than the rustler nitro. Traxxas says the nitro rustler goes 55mph, i find it hard to believe that the jato is faster. The volcano is pretty fast, not 60+mph though. it is only single speed tranny, but i bought it for off road, dirt driving so i am not so interested in doing 60mph on a bumpy, jumpy track off road place anyway, would cost too much to fix in parts. i am getting the tornado xp delivered tomorrow so i will let people know about that. as far as the truck though, for under $200 you cant go wrong, i am very haddy with it, even if it does 40mph. Maybe i will buy the radar gun over the weekend and try it out.
