The newest generation from the Ultima series. All the years of competition know-how and the latest technology has been condensed into this new Ultima 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.
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 (±0°/＋2°/＋4°), 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
CCompletely new design aero body features a narrow cabin and optimized window angle for more responsive feel.
