ULTIMA undergoes a full model change with evolved performance to lead the RC racing world.

A new era in 2WD buggy racing has begun.

While EP 2WD racing buggy rivals jostle for position, the ULTIMA consistently competes at the highest level. To maintain its advantage, the ULTIMA has undergone a complete evolution into the new RB6 model. A duralumin chassis with tungsten diff balls, one-piece steel front wheel shafts and one-piece shock caps combine to deliver a sharp increase in speed. These features also improve durability and strength so the risk of damage during practice or club racing is reduced, allowing you to run your machine for the pure fun of it with peace of mind. The suspension design incorporates gullwing rear suspension arms and provides precision setting of the damping ratio to achieve optimal grounding characteristics. Superior grip allows free control of traction. In addition, the midship motor layout matches the model to high-grip surfaces such as carpet to produce nimble control and movement. The motor can be converted to a rear mount to produce optimal performance on rough road courses as well. Compatible with various battery sizes, a mount for separate or short-type Li-Po batteries is included that allows the mounting position to be moved between front-rear. The new ULTIMA RB6 racing machine is designed to respond decisively to the driver_Ñés commands and will take your driving performance and results to the next level.

• On high grip surfaces, the midship motor layout delivers decisive turning and traction.
  
• Various battery types can be installed such as straight, separate or short types. Changing the front/rear position of the battery can control the center of gravity.
• Roll rigidity setting can be adjusted with the number of screws used. Side guards contribute additional vertical rigidity.
• Duralumin chassis provides increased rigidity. Incorporates_ÑÒ7075-T6_ѝ, the strongest material used in RC. Hard anodized surface increases durability and stepped edges reduce interference with the road.
• Gullwing type rear sus arms produce ideal damping performance. Aluminum drive hub locks wheels securely.
• New steering system allows setting of ideal ackermann ratio. By setting according to racecourse conditions, higher cornering speed can be achieved.
• Special RB6 front-forward cabin body achieves excellent turning and straight speed performance. New wing delivers optimal balance setting for turning and acceleration. Produces great traction without diminishing maximum speed.
• Caster angle on new front hub carrier can be changed by replacing bushings. Hardened ball ends and adjustable chromoly rods increase crash resistance. One-piece steel drive hubs provide precision control and strength.
• Velvet coated big bore shocks deliver great traction and performance over gaps. Also, one-piece shock caps dramatically improve durability. Features X-GEAR springs that provide reliable spring effect and consistent road holding.
