Kyosho Ultima RB7 2WD Competition Buggy

- Kyosho Ultima RB7 2WD Competition Buggy -

Having achieved the golden double of 1st place and TQ in the 2WD class at the 2013 IFMAR Electric Off-Road World Championship, the RB6 series has maintained its lead through continuous running change improvements. The RB7 represents the next significant evolution that excels with the increased power & speed on the high-grip artificial turf and carpet surfaces of today's off-road racing scene. Based on the ultra low center of gravity of the RB6.6 low-down midship, the RB7 features improved rigidity and control from its 4mm shorter wheelbase and lightened new design main chassis, combined with a completely new aero body design, high downforce rear wing, and new design front and rear sus arms and steering knuckles. The RB7 provides the reliability and durability necessary for high-intensity racing with wider scope for setting adjustments to deliver a racing edge. With driver and machine synced into one, you and the RB7 will make an unstoppable combination.

- Rear wheel drive racing buggy with lowdown midship layout excels on high-grip surfaces.
- Features short Li-Po battery specifications, typical in electric off-road buggies. Battery bar provides easy installation and detachment of battery.
- Tungsten balls in the ball diff combine precision with long life.
- Screw-stop clamp-type hexagonal wheel hubs on rear realize precision rotation and traction performance.
- Large capacity slipper clutch comfortably handles the output of high-power motors.
- Revised center mount design optimizes chassis rigidity.
- Formidable styling with aluminum parts anodized in gun metallic.
- Features X-GEAR ball diff grease, high-graphite grease and shock springs.
- With additional parts, the gearbox setting can be converted for rear motor, 3-gear midship and 4-gear midship, to adapt the machine to different racing situations.
- Huge lineup of optional parts are available for fine tuning performance and style.

After a long testing period on the ultima chassis, the latest in genuine Kyosho quality comes in the form of our all new 1/10th 2wd buggy, the RB7!

ELECTRIC POWERED 2WD RACING BUGGY KIT

Strictly focused on EP 1/10th scale 2WD competition, the Ultima RB7 has been tested and designed to perform at the very top level. Thought through from the quality of the materials to the precise parts engineering design, this competition kit is for all types of racers who love racing. Kit requires Transmitter, receiver, motor, ESC, servo, tires, battery and charger to complete.

ULTIMA RB7 side chassis image

ULTIMA RB7 side body image CHASSIS: Using the same A7075 T6 grade aluminum as the RB6.6, the 0.5mm thinner RB7 main chassis is milled to realize lighter weight with optimal rigidity.

Wheelbase: With a 4mm shorter wheelbase than the RB6.6, the RB7 realizes improved high-speed cornering performance.

Gear Box: Gearbox has been specially designed for low down 3-gear midship and ultra-low center of gravity to realize exceptional performance on high-grip surfaces such as carpet, artificial turf and hard-packed soil. With additional parts, the gearbox setting can be converted for rear motor, 3-gear midship and 4-gear midship, to adapt the machine to different racing situations.

Big Bore Shocks: Improved stability over jumps and rough surfaces is achieved with the change to resin shock caps (from aluminum) on the same Big Bore shocks used on the RB6.6. Shock pistons (front φ 1.6mm x 2 holes and rear φ1.7mm x 2 holes) deliver outstanding performance through all sections of the course. Includes 2 bottom spring retainers(short and standard). The short lower retainer is best suitable for carpet tracks.

Front Suspension Arm: Newly designed gull-wing type front sus arms deliver deeper suspension stroke for superior traction.

Front Hub Carrier & Steering Knuckle: Newly designed steering knuckle realizes optimal Ackerman ratio for improved cornering speed. Proven features such as hub carriers with caster angles that can be adjusted with bushes (+/-0deg/ +2deg/ +4deg), steel one-piece wheel shafts, hardened ball ends, and black chrome adjustable rods are all inherited from the RB6.6.

Rear Suspension Arm & Universal Joint: Like the front, the rear sus arms are gull-wing type as per the RB6.6 but on the RB7 bushes can be used on the holed section to adjust sus arm length. For compatibility with latest high power loads, the joint section of the universal shaft has been modified to stop pins coming loose.

Aluminum Rear Suspension Mount Holder: Aluminum rear sus mount holder in the RB7 delivers increased strength compared to the RB6.6 resin holder that required cut and trimming. The distance between the suspension shafts (rear toe angle) can be changed by replacing the bush.

Body: Completely new design aero body features an inline center fin which runs down the center section and continues to the rear wing. The new design increases traction, stability and corner speed.

Narrow Cabin: Completely new design aero body features a narrow cabin and optimized window angle for more responsive feel.

Rear Wing: Newly designed 1.0mm thicker rear wing and the change from hook & pin to screw-on mounting provides greater rigidity, durability and superior traction performance.
