The most dominant IFMAR electric off-road racing machine charges into the new season with key running changes!

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.

●New larger capacity slipper clutch is compatible with high power motors.

●Gun metallic anodized aluminum parts produce a formidable finish.
