Overview

The boom of the 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.

Available: January 2010

Features

* New Carbon Fiber Composite Chassis, 40mm longer than RT5

* Inpact Resistant Front, Rear and Side Bumpers

* New Scale Looking Wheels

* Newly Designed Uni Patern Tires

* Equipped With 12mm Wheel Hex Hubs

* 1mm Think High-Impact Lexan Body For Superior Durability

* Sealed Gear Box with 4pcs metal bevel gears

* Lipo Compatible ESC

* Composite Chassis - The chassis plate is 40mm longer then the RT5. Light and strong, featuring a specially formulated carbon fiber composite for the best balance of peformance and durability. Strategic braces molded into the chassis enhance the stiffness without adding any unnecessary weight. Seperate front and rear clips allow fast and easy removal of the front and rear end of the car, which makes maintenance and repair much easier. Designed to accept stick packs and 2 cell lipo packs, the RT5 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 smaller, more compact housing that keeps the motor as low and close to the transmission as possible, which reduces CG and improves bump handling. The three- gear transmission features a new heavy duty SP idler gear an sealed gear box with 4pcs metal bevel gears.

* 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 seperate 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 nub 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 Acherman geometry throughout the entire range of steering motion. The steering plate (center link) features horizontally mounted ball studs, which mean the Acherman can be fine tuned by using shims behind the ball studs offering a nearing infinite range of adjustments.

* Captured Hing 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 possibl y, as are the shocks, to keep the mass as low 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. The threaded adjuster features an O-ring that prevents the preload settings from moving, which ensures consistent performance from start to finish.

* 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 most RT5 optional parts.

What is a Ready Set

* A Readyset is a fully assembled model that includes nearly everything you need to run. Body Color scheme is complete so only consumables like batteries and fuel are required so you can start operating the model without delay.

Ready Set Contents:

* Pre-Assembled Chassis

* Pre-Painted Body

* Lipo Compatible ESC

* G20 Stock Motor

* Perfex KT6 Transmitter and R/C System

* Cross Wrench

Required For Operation:

* AA- Batteries x8

Ultima SC-R

Features:

Velvet Shocks - Kyosho is well known for silky smooth shocks and the new Triple Cap shocks included with the new Ultima SC-R are no exception. The shock body consists of three major components a top cap, velvet coated threaded bodies, and a lower cap. The velvet coated shock bodies feature a threaded spring pre-load collar for quick and easy adjustment. The threaded adjuster features an O-ring that prevents the preload settings from moving, which ensures consistent performance from start to finish. The lower shock cap allows for quick and easy maintenance of the double O-ring seals.

Ball Diff - Features an externally adjustable internal ball differential that uses standard 3/32–inch diff balls and 1/16–inch thrust balls. Includes tight–fitting molded dust cover to protect pinion and spur gear.

Universal Swing Shaft - Equipped with universal swing shafts for better power transfer and maximum efficiency.

Hard Adjustable Rods - Featuring Chromoly turnbuckles, the use of stronger material means the turnbuckles can be made lighter and stronger than the original steel units.The rod ends feature a stronger material that is more durable and resists contamination from dirt. This means that the rod ends stay tighter and are less likely to be damaged or separated from the ball stud in the event of a hard crash.

Teflon Shielded Bearings - Ball bearings are the standard for reducing friction and wear, and to increase efficiency. It’s nice to know that the Ultima SC-R is equipped with a full set of 18 Teflon-sealed ball bearings used throughout the drivetrain and transmission to keep things running smooth.

Steel Suspension Bushings - Give you a much more precise and consistent suspension response.

Composite Chassis - The chassis plate is 40mm longer then the RT5. Light and strong, featuring a specially formulated carbon fiber 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 car, 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.

Rear Suspension - The rear suspension is 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 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 Ackermann 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 nearing 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 hinge pins are much more secure and less likely to come loose.

Kit - Giving you a 100% chassis that you build from the ground up. You have full control of your race machine, not just tuning but also building it. Legendary Kyosho performance at your finger tips.

As a different driver achieved each victory, the performance of the ULTIMA SC-R has come into sharper focus. Compatible with ROAR racing regulations, the ULTIMA SC-R kit is fully equipped with a range of high performance optional parts for a racing edge right from the start and at a great value. Similar in size to a 1/8-class model, the lightweight finish weighs in at only 2,000g and a popular Readyset version is already available (Ultima SC RTR) for those who like to hit the dirt without delay. Short course truck racing has never been more dynamic with the advanced design and performance of the new ULTIMA SC-R!

Features

* Ball Differential Set - Includes an optional ball diff set (UMW602) as standard equipment, which provides efficient traction transfer and precision adjustment to suit all racing conditions.

* Velvet Coated Shocks - Kyosho is well known for silky smooth shocks and the new Triple Cap shocks included with the new Ultima SC-R are no exception. The shock body consists of three major components, a top cap, velvet coated threaded bodies, and a lower cap. The velvet coated shock bodies feature a threaded spring pre-load collar for quick and easy adjustment.

* Steel Sus. Bushings - Steel suspension bushings provide strength and endurance for aggressive driving and superior durability.

* Revised Rear Hubs - Factory drivers have determined that only one of the hinge pin holes was ever used in the original RB5 wheel hubs, so the extra hole was eliminated for the new SCR. Combined with a new, more durable material, these hubs are not only much stronger, they're also lighter and the new geometry produces more stable handling characteristics

* Carbon Composite Chassis - The chassis plate is 40mm longer then the RB5. Light and strong, featuring a specially formulated carbon fiber composite for the best balance of peformance and durability. Strategic braces molded into the chassis enhance the stiffness without adding any unnecessary weight. Seperate front and rear clips allow fast and easy removal of the front and rear end of the car, 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 - Features an externally adjustable three-gear design with an internal ball differential that uses standard 3/32inch diff balls and 1/16inch thrust balls. Includes tight-fitting molded dust cover to protect pinion and spur gear.

* Rear Suspension Symmetry - The arms are symmetrical so a single replacement arm can be used on either side of the car. The inside of the arms are attached to the chassis using separate suspension mounts, which will allows anti-squat adjustment. Vertical ball studs for both ends of the upper link suspension geometry can be fine-tuned with shims.

* 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 more responsive suspension. The bearings are under less stress, and they're better shielded from the elements.

* 12MM Hex Wheel Hubs - 6 contact points spread the load on the wheel to prevent stripping and the larger, flat mounting surface keeps the wheels running straight and true.

* 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 Ackermann geometry throughout the entire range of steering motion. The steering plate (center link) features horizontally mounted ball studs, which means the Ackermann 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 hinge pins are much more secure and less likely to come loose.

There’s no doubt that, for a RC fanatic, our job has its perks. For instance: Last Sunday at Hot Rod Hobbies, we got to drive Kyosho’s new Ultima SC—a vehicle that many employees AT Kyosho haven’t even seen yet. With the offer to drive the Ultima SC and help Kyosho film some video footage, we were eager to meet at Hot Rods for some hot laps.

DSC_8706rcp.JPG

Kyosho met us at Hot Rod Hobbies for Sunday afternoon’s open practice day (which provided plenty of moving obstacles) in an effort to beat the first rain of the Southern California winter season, and we set up shop on a nearby pit table to get to work. Once batteries were charged and installed, it was time to hit the track. In all, we burned through a dozen battery packs or so. Plenty of run time to get an idea of the truck’s capabilities.

DSC_8758rcp.JPG

Although the body, tires, and wheels are not officially-licensed replicas of full-size race trucks, the whole package certainly looks cool and dutifully respects the Short Course Truck class style and dimensions. Protective front and rear bumpers with beefy skid plates provide plenty of crash absorption while enhancing the truck’s scale appearance, and the full-fendered truck body’s aggressive shape mimics a real off-roader.

DSC_8770rcp.JPG

The truck was incredibly fun to drive, displaying solid handling characteristics and sound jumping ability around Hot Rod’s technical layout. What do we really think? You’ll have to wait for the full review in a future issue of RC Car Magazine.
