The boom of R/C short course racing is spreading across the world and is becoming a part of some of the major races in the U.S., ROAR already has announced this class and regulations have been introduced. The Ultima SC has been designed with all of the racing performance in mind and meets all ROAR regulations. This Ready-Set (Ready to Run) is not just a backyard basher but a race ready chassis with many of the high performance traits from the Ultima RT5.

Features

  • New Carbon Composite Chassis, 40mm longer than RB5

  • Impact Resistant Front, Rear and Side Bumpers

  • New Scale Looking Wheels

  • Newly Designed Uni Pattern Tires

  • Equipped With 12mm Wheel Hex Hubs

  • 1mm Thick High-Impact Lexan Body For Superior Durability

  • Sealed Gear Box with Gear differential

  • Lipo Compatible ESC

  • Composite Chassis - The chassis plate is 40mm longer then the RB5. Light and strong, featuring a specially formulated carbon composite for the best balance of performance and durability. Strategic braces molded into the chassis enhance the stiffness without adding any unnecessary weight. Separate front and rear clips allow fast and easy removal of the front and rear end of the truck, which makes maintenance and repair much easier. Designed to accept stick packs and 2 cell lipo packs, the SC chassis features an adjustable battery mounting position that allows you to shift weight bias to suit track conditions and your driving style.

  • Transmission - The new transmission features a small, compact housing that keeps the motor as low and close to the transmission as possible, which reduces CG and improves rough track handling. The three-gear transmission features a sealed gear box with an all new gear differential.

  • Rear Suspension - The rear suspension are symmetrical so a single replacement arm can be used on either side of the truck, saving money and space inside your pit box because you don't need to carry as many replacement parts. The inside of the arms are attached to the chassis using separate suspension mounts, which will allow anti-squat adjustment. Vertical ball studs for the both inner and outer rod ends of the upper link means the rear suspension geometry can be fine tuned with shims.

  • Front Suspension - 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 to. The standard position of the suspension mount produces 25 degrees of hinge pin angle in the front arms, but simply flipping the suspension mount increases hinge pin angle to 30 degrees. The added flexibility of having adjustable hinge pin angles means you have more options when it comes to setting up your truck. Like the rear arms, a single replacement arm can be used on either side.

  • Floating Axles - 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 extremely more responsive suspension. The bearings are under less stress, and they're better shielded from the elements.

  • Steering Assembly - The steering bellcranks 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. The steering plate (center link) features horizontally mounted ball studs, which mean the Ackerman can be fine tuned by using shims behind the ball studs offering a nearly infinite range of adjustments.

  • Captured Hinge Pins - A simple button head screw captures all the outer hinge pins of the Ultima SC. 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. This means that the hing pins are much more secure and less likely to come loose.

  • Shock Towers - The front shock tower is mounted as far back on the chassis as possible, as are the shocks, to keep the mass as centered as possible. 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 Composite Shocks - The composite shock bodies feature a threaded spring pre-load collar for quick and easy adjustment.

  • Fan Cooled 20 Turn HP Motor - High performance and longevity are the key features of the G20 motor. It has an internal cooling fan so the motor stays cool and strong from run to run.

  • Reliable Perfex Radio System - Pre-installed KR6 AM. receiver and a reliable Perfex KT6 pistol grip transmitter.

  • Lipo or NiMh - The Perfex ESC is compatible with either Lipo 7.4v 2cell or 8.4v NiMh (7cell).

  • RT5 Compatible - Most parts are compatible with the Ultima RT5 and RT5 option parts.
