26 years after the Ultima’s first race victory, Team Kyosho International’s Jared Tebo (America) drives the Ultima RB6 to dominate the IFMAR Electric Off Road Car Championship held in California in September 2013 with TQ and championship victory. The world’s most formidable racing machine has now been modified to deliver superior performance on high-grip running surfaces. In addition to the key advantages of the previous model (No.30068) such as high-rigidity 7075-T6 duralumin main chassis, adjustable battery mounting position for changes to weight distribution, choice of midship or rear motor mounting systems, Big Bore oil shocks for excellent surface tracing, the new model features the selection of rear wing, rear suspension arms & shock springs to suit the midship motor mount setup. These changes realize improved durability and broader setting options for stability on high grip surfaces including artificial grass, carpet and hard-packed dirt. The new RB6 is fully loaded and designed for racers ready to challenge serious competition or upgrade for the next big racing event.
Designed with the latest race-winning specifications including high-rigidity duralumin main chassis, large capacity big bore shocks for excellent surface tracing, and choice of two motor layouts. Straight, separate or short battery types can be installed. Also, short battery type allows mounting position and weight distribution to be selected to suit different surfaces and layouts. Motor mount setup can be either midship mount for superior performance on high grip surfaces like artificial grass, or rear mount that maintains solid grip on low mu surfaces with no sand or gravel. 7075-T6 duralumin + hard anodized main chassis realize high-rigidity. Side plates that produce pitching rigidity also contribute to improved durability. RB6’s unique forward cabin type body delivers sharp cornering and stability. Improved cornering and durability is achieved by replacing the rear wing combination with the Step Wing 3.0 (LA373). Increased mounting holes for rear suspension arm (UM713B) provides wider setting options for the midship motor configuration. Change the shock springs to medium (XGS013) to achieve more rear grip. Crash resistance improved with installation of one-piece steel drive hub, hard type ballends and chromoly adjustable tie rods. Also, caster angle can be changed by replacing bushes on front hub carrier. Steering crank system produces excellent off-road turning performance from optimal akerman ratio setting in addition to linear control feel.
