the blitz is definately a "short course" truck which is different from a stadium truck such as a T4 or a xxxT or a rustler or a mt2!!!
short course truck's can be 2wd or 4wd and are usually quite a bit wider than a stadium truck.
both can be very fun!!! but if your going to run in grass a monster truck is probably your best bet,even they can struggle a little
in grass!!
