Kyosho Ultima RB5 30074B Electric Car Kit

Kyosho announces the new Ultima RB5 electric racing buggy. It's a virtually all-new design that is the result of years of R&D and includes the collective experience of the world's most experienced RC racing drivers and engineers from the world's most experienced RC racing company. The main goal of the new Ultima RB5 is simple - to win the next IFMAR World Championship.

The new Ultima RB5 only shares rear hubs with the Lazer ZX-5 and a few common hardware items, but the essential and distinguishing components of the car, such as the chassis, transmission, bulkheads, shock towers, suspension and the sleek aerodynamic body, are all new. Each aspect of the car is specially designed and tested to produce maximum performance. Likewise, the materials chosen for this new Ultima are exhaustively tested - all with the goal to create the ultimate no-nonsense competition car that's ready to take on the world.

• Chassis - The chassis plate is light and strong, featuring a specially formulated carbon fiber composite for the best balance of performance and durability.
• Transmission - The new transmission features a smaller, more compact housing that keeps the motor as low and close to the transmission as possible, which reduces CG and improves bump handing.
• Rear Suspension - The rear suspension arms are symmetrical so a single replacement arm can be used on either side of the car, saving money and space inside your pit box because you don't need to carry as many replacement parts.
• Front Suspension - Longer, straighter and symmetrical suspension arms connect to a narrow front bulkhead. The bumper/skid plate, suspension block, nose plate and front bulkhead all come together to form a very rigid assembly, to which the front suspension arms mount.
• Offset steering hubs make high-speed handling a dream, while floating axles ride in bearings that are mounted in the hub instead of the wheel. This moves the weight of the bearings inboard for more responsive suspension, the bearings are under less stress, and they're better shielded from the elements.
• Steering Assembly - Ball bearings provide smooth movement of the steering bellcranks, which are mounted on the chassis at the same angle as the suspension arms. This eliminates bump steer and produces more accurate Ackerman geometry throughout the entire range of steering motion.
• Captured Hinge Pins - A simple button head screw captures all the outer hinge pins of the Ultima RB5. The rear inner hinge pins are truly captured between the suspension mounts, and the notched inner front pins are secured with a setscrew through the front suspension mount.
• Low-Profile Shock Towers - The front shock tower is mounted as far back on the chassis as possibly, as are the shocks, to keep the mass as low as possible. Likewise, the rear shock tower is also designed to keep a low profile, yet allow enough suspension travel to ensure the best possible handling. The shock towers are molded from an exhaustively tested composite, which is much more costly to produce than shock towers made from woven graphite, but will also provide greater durability.
• Threaded Aluminum "Triple" Shocks - Kyosho is well known for silky smooth shocks and the new "Triple" shocks included with the Ultima RB5 are no exception. The shock body consists of three major components - a top cap, threaded body, and a lower cap.
• Low-Profile Body - no less than ten versions of the new body for the RB5 were thoroughly tested to maximize performance and to ensure that you have the best-looking car on the track.
