Description
Kyosho announces the new Ultima RT5
electric racing truck. It's a all-new design that is the result of
years of R&D and includes the collective experience of the world?s
most experienced RC racing drivers and engineers from the world?s most
experienced RC racing company. The main goal of the new Ultima RT5 is
simple - to win. Each aspect of the truck is specially designed and
tested to produce maximum performance. Likewise, the materials chosen
for the new Ultima are exhaustively tested all with the goal to create
the ultimate no - nonsense competition truck that?s ready to take on
the world!

- Composite Chassis
- The chassis plate is 23mm 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 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 internal ball differential
that uses Tungsted Carbide Differential Balls and 1/16-inch thrust
balls. The differential is also externally adjustable, a dust cover
fits over the adjustment holes so the thrust bearing last much longer.
An injection molded gear cover is included which better fits the motor
plate to minimize dust and debris for longer gear life.
- 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. The new rear
wheel hubs feature a new quick release function, allowing you to make a
quick tire change with no tools. 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
- Ball bearings provide smooth movement of the steering bellcranks,
which 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 Hinge Pins
- A simple button head screw captures all the outer hinge pins of the
Ultima RT5. 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.
- Velvet Coated Shocks
- Kyosho is well known for silky smooth shocks and the new ?Triple
Cap? shocks included with the new Ultima RT5 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.
- Hard Rod Ends
- The rod ends feature a stronger material that is more durable and
resists contamination from the dirt. This means that the rod ends stay
tighter and are less likely to be damaged or seperated from the ball
stud in the event of a hard crash.
- Teflon Sealed Bearings
- Ball bearings are the standard for reducing friction and wear, and
to increase efficiency. It?s nice to know that the Ultima RT5 is
equipped with a full set of 18 ?Teflon-sealed? ball bearings used
throughout the drivetrain and transmission to keep things running
smooth.
