RE: Cheapest Nitro Stadium Truck
I've never seen one run but the evader (nitro) has pretty nice stuff for the $$. A OS built .18, alum. threaded shocks, lots of hop ups avail. too.
Or you could spend a little more and get a Nitro rustler, with the 2.5 and electric start.
If all out competition is what you want the nothing beats a LOSI, or Team Associated, but plan on spending more.
