After the IFMAR Electric Off-Road World Championship in Ultra high grip surfaces such as artificial turf and carpet have become mainstream in off-road racing since the 2015 IFMAR Off-Road World Championships run at Yatabe Arena in Ibaraki Japan. To stay ahead of these constantly evolving trends, Kyosho’s Ultima RB6 has been updated into the new 6.6 model. While maintaining the superiority of the proven suspension and steering in the RB6, the new 6.6 model features a selection of 4 different gearboxes: “Rear Motor”; “3 Gear Midship”; “4 Gear Midship”, and “Lowdown Midship”. In addition to the ever-reliable rear motor for looser surfaces, the 6.6 features midship transmissions for higher grip dirt surfaces and a newly designed lower C of G lowdown midship transmission for ultra high-grip surfaces such as artificial turf and carpet. With detailed precision setting capability, this single machine is compatible with any surface type that a racer is required to drive on. Also, the wider 7075-T6 grade main chassis with side guards is unchanged to deliver the cornering advantages of its width. When using the midship layout, either straight or sideways battery mounting orientation can be used to fine-tune the chassis weight distribution effect on running performance.

Incorporates advanced specifications including: high rigidity 7075-T6 main chassis, surface-tracing Big Bore shocks and choice of motor layout.

With the RB6 model’s width, the 7075-T6 grade main chassis features increased rigidity and lower center of gravity to perform in both high-speed and high-grip race conditions.

Battery can be oriented straight or sideways (with midship layout) for precision adjustment of chassis weight distribution to suit the grip and layout of various racing courses.

Includes sus pins that allow 3 caster angle settings: 0°, 2° and 4°. Precision setting adjustment enables superior cornering and performance over gaps.

Uses the same one-piece steel wheel shafts, hardened ball ends and chrome-moly steel adjustable tie rods as the previous model for superior crash resistance and durability.

Features gull-wing shaped suspension arms that enable maximum possible stroke from the rear shocks. Equipped with medium shock springs for extra rear grip.
