The eclass doesn't come with the k-factory belts, it comes with the stock black ones. The sirio EVO II is doing awesome now in the world nationals! The kyosho team is running them and they are expected to be in spots 1 - 6 and have 8 out of the top 10 drivers. I have my Jr XS3 synthesised radio in my car. You kinda have to mod the receiver location. This car will only accept micro receivers with the stock setup. It comes with the k-factory anti-roll bars , the push type clutch, and the front oneway, and carbon fiber upper deck and thats about it.
