KWT-Nitro, since you run on a harder surface you may want to look into purchasing a BCE chassis because of the wear characteristics. The BCE is built out of, IMO, better materials.
Foothills 8ight, the BCE chassis is a step(or two
) better than the Racer Roller 2.0 chassis. You may find a Losi 2.0 chassis on Ebay for cheaper than a hobby store if you looking to go that route. If you looking at paying the full amount for the Losi 2.0 chassis I would buy a BCE instead.
