With the Optima Mid KYOSHO brought in the 80 years the first mid-engined 2WD buggy on the market. Viewed more as an innovation at the edge of this technology back around today. With the introduction of the Ultima 2WD in April 1987 KYOSHO enthusiastic customers again with new technology and sensational technique! In the same breath, the competitive class was 1/10 2WD-OffRoad. Thus began the golden era of success with the Ultima series, which is still remembered. back now brings KYOSHO the concept of a mid-engine in the 2WD models, and combined with the Ultima RB6, the philosophies of the tail – and mid-engine drive in a single model. The result is a superb racing machine, developed and designed by today’s standards in materials and technology.
Chassis The RB6 is a hard-anodized high-tech chassis built from 7075 aluminum. With kickup at the front and angled side trays, mirrors the chassis of the RB6, the technology of the 1 :8-off counterparts in 1:10 scale again. With an additional length of 13mm, it supports the model is positive and leads to increased stability.
Power transmission & gear The all-new gearbox unit is designed especially small and easily. This allows the engine and transmission are placed very low in the chassis, making the overall center of gravity of the model is positively influenced. The transmission is in the rear-engine version and a three-tier manages the force of a ball differential to the rear wheels. The ball differential is adjustable from the outside, the set points are provided with dust covers. In the mid-engine configuration, the gear four stages to the influence of the motor rotation direction is positive to be transferred to the traction of the model and to provide a more stable acceleration.
Rear axle , the entire rear axle is symmetrical, thus results in low maintenance costs. Track and caster angle can be varied by varying the mounting arm shots. The upper arms are equipped with R / L-threaded rods and pivoted on ball heads. Through the use of spacers, the angle of the upper wishbone be varied. Power is transmitted to the rear wheels via propeller shafts efficiently, which shine with a perfect finish. The use of upward angled wishbones more agile steering response despite high stability is achieved on holey ground.
Front The front is symmetrical, it has a particularly long and narrow wings.Thus, the entire front axle has a particularly compact and light. The bearing of the front wheels in special low-friction ball bearings that are fitted with a fiberglass plate effectively sealed against dust. All parameters such as track, camber and caster can be adjusted with little effort.
Battery layout in the chassis of the RB6 are used both in the rear-engine configuration and in the mid-engine configuration, all current battery types into place. The chassis offers the possibility to stick batteries to use as well as saddle-packs or shorties, no matter which engine configuration is in use.
Steering & Servo Saver The all new and ball-bearing steering geometry made of black anodized aluminum is the same angle as the front control arm, thereby forming the Ackermann effect over the entire steering range is achieved. The use of deflection elements of aluminum, the steering is precise even in the toughest conditions ever. The front and rear axle are each secured with a single screw. This means that the pins be secured against falling out and can be changed with a handle.
Shock towers , the shock towers are also made from a special synthetic material with fibers. This material has the requisite hardness in the race, but also has the necessary flexibility in the event of a hard crash. . Both shock towers have numerous mounting points to the model in every possible route tune.
“Triple” BigBore oil shocks , as the name implies, consist BigBore oil shocks of the RB6 of three components: the upper shock cap, the damper housing and the lower damper cap . The shock absorbers are made from high quality aluminum and are characterized by their ease. The setting of the preload is particularly sensitive about a knurled nut with fine thread. A special feature of the knurled nut on an O-ring that prevents unwanted rotation in racing.
Springs When Ultima shock absorbers are used RB6 springs from the house of X-Gear. These springs will go through before delivering a quality control in the controls include the proper hardness. Thus, a constant damping characteristic is ensured.
Body more than 10 different body styles were in the wind tunnel and track testing, to achieve the perfect blend of performance and appearance. So united shaping the technology of performance-oriented designs and Cab-Foward nevertheless radiates a touch of the first Ultima 20 years ago. The result is a high-tech body ensures the best possible output for any situation.
