Since its release in 2003 the RC10B4 remains undefeated on a world level, having won five IFMAR World Championships in a row. In commemoration of their most recent 2WD Off Road World Championship win, Associated are proud to bring you the RC10B4.1 Worlds Car kit. The kit comes with the chassis spec’d out the same as the Team Associated buggies that were driven by Ryan Cavalieri, Ryan Maifield and Neil Cragg at the 2011 IFMAR World Championships in Vaasa, Finland. It has all the latest Factory Team features, starting with the +8mm B4.1 chassis conversion which greatly improves the overall stability and handling of the buggy, making it easier to drive and lower your lap times. Topping off the +8mm B4.1 chassis is the Pro-Line Bulldog +8mm body. Other features include the Factory Team 0° rear hubs, Factory Team rear ballast weight, and the new B4.1 Worlds Car setup sheet.
