ray remember that the warpspeed demon has the battery layout changed and the adjustable wheelbase! also the option to run the nitro or electric steering rack is helpful. you also have the option of calling warpspeed and have custom changes to the chassis, I know its on a small production run but the options are there if you are bored with the old tc3. so all those people that want a consistant car with a double deck designed and refind suspension options its the way to go.
