RC10B4.1 Worlds Car

RC10B4.1 Worlds Car

5-Time I.F.M.A.R. World Champion!

Since its release in 2003 the RC10B4 remains undefeated on a world level having won five I.F.M.A.R. World Championships in a row! In commemoration of our most recent 2WD Off Road World Championship win, we are proud to bring you the RC10B4.1 Worlds Car kit. The RC10B4.1 Worlds Car 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 I.F.M.A.R. World Championships in Vaasa, Finland.

The RC10B4.1 Factory Team Worlds Car kit has all the latest Factory Team features, starting with the +8mm B4.1 chassis conversion. The +8mm chassis greatly improves the overall stability and handling of the buggy making it easier to drive and lowering your lap times. Topping off the +8mm B4.1 chassis is the Pro-Line Bulldog +8mm body.

Other features include the Factory Team 0 degree rear hubs, Factory Team rear ballast weight and the new B4.1 Factory Team Worlds Car setup sheet.

Magazine Review
The WC version and its 8mm extended chassis really helped close that gap between myself and the heroes of the class, boosting my confidence that I can actually get into the winner's circle with this car; maybe not at a Worlds event, but certainly on the club level. That's what it's all about anyway, right? --RC Driver, August 2012
