or me, nothing matches the excitement and satisfaction of assembling
a brand new car kit. And with XRAY’s T2 ‘009 US Foam-Spec Edition,
that process is not only enjoyable, but it also results in one of the most
competitive, track-ready, fully adjustable and aesthetically pleasing
touring cars on the market today.
Mr. Filipow is in the house.
Don’t overgold, it’s dangerous.

Driveshafts: The US edition utilizes
slightly shorter 50mm driveshafts than the EU
edition. This allows the car to transfer weight
quicker, left to right, on high traction surfaces.

most noticeable

metallic orange. Love it or hate

We know of some “Asia” versions out there.
XRAY demonstrates
that they are
prepared for the
transition to LiPo batteries with
the inclusion of LiPo Pads. These
pads, which are actually carbon
fiber shims, are bolted between
the aluminum bulkheads and the
top deck. Once installed, the LiPo
Pads create an additional 2.3mm
of clearance for easy fitment of
most LiPo batteries.
Multi-Flex: In combination
with XRAY’s Multi-Flex Technology
adjustment, the rigid 3.5mm
chassis can be adapted to a wide
range of grip levels. The US
edition also includes removable
aluminum chassis stand offs,
which will keep it poised in the
highest of traction conditions.
LAYOUT:
SUSPENSION
Great traction, incredible
corner speeds and
amazing lap times.
Quick-Saver: Incorporated along with the factory
assembled servo saver are five Ackermann settings.
More or less, Ackermann is easily accomplished by
loosening a single screw and sliding the Quick-Saver to
one of the stepped positions.
There is no AUS version, sorry.

Testing
Fortunately, Southern California is now home to a brand new, permanent
indoor carpet track. OCRC Raceway in Huntington Beach recently
expanded their already world-class off-road facility to include a 75 x 75foot on-road track. I was one of the first racers to hit the rug with foam tires
and was able to complete two full days of non-stop testing and practice.
Acceleration and Speed • Foam
tires, carpet and modified motors—you know
this equates to great traction, incredible corner
speeds and amazing lap times. Starting with
the kit setup, the car had a neutral and very
predictable balance, despite the increasing grip
level on the track surface. It’s no wonder that the
modified foam classes are waning in participation
throughout the U.S.; it requires a lot of skill
and nerve to pilot one of these missiles. To do it
consistently, lap after lap, and in traffic, is not for
the weak at heart.
Rating: 9.5/9.5
Filipow has skill and nerve.
Braking • The OCRC carpet track is a little
tight for the power of a 4.5 brushless, so using
the brakes was required. The car was neutral
under braking and the foam tires added plenty
of stability.
Rating: 9
Low-Speed • Low speed!? On foam tires
and a 4.5 brushless? There’s no such thing as
“low speed!” However, on the “slower” sections
of the layout, the ‘009 rotated quickly through
the 180 degree sections. Off power, the kit
setup remained very balanced, front to rear, and
provided the fast rotation required to get back on
the throttle.
Rating: 9
102 | WWW.RC411.COM
High-Speed Handling • This
car is responsive, even at very high speeds.
Turn the wheel and the car turns. Instantly.
Keeping the power down thru the sweeper
only requires a finger full of nerve; the car
itself is more than capable.
Rating: 9
Wrenching
Maintenance • Working on a chassis
of this caliber is truly enjoyable. Thanks to
the precision engineering and machining,
every part on the ‘009 fits perfectly, right out
of the box. Each carbon fiber and aluminum
component is beautiful. There is little-to-no
flash on the molded parts. There is no slop and
no shimming is required. Combine this kit with
a set of HUDY tools to work with, and you
almost get the sensation that you’re a Formula 1
mechanic. Spur gear changes can be tedious and
will require some practice. Setting the gear mesh
can be tedious, too. Take your time to get it
right the first time, especially with 64-pitch, and
you won’t be needing to replace stripped spurs.
Learning how to identify and install the roll
center holders will require some patience as well.

PERFORMANCE TEST
Wear and Tear • Overall, this car is
extremely durable. Being a chassis optimized
for high traction conditions, every part is
tailored to eliminate unwanted flex from the
platform. From the XH (extra hard) molded
arms and uprights, to a wider top deck
supported by removable aluminum standoffs,
this car is majorly stiff. The aluminum diffs
come pre-assembled, but they will need to
be set to the correct tension. Utilize a little
patience and follow the diff adjustment
directions outlined in the kit and you will be
rewarded with a long lasting and smooth diff.
Rating: 9
Tuning • The ‘009 responded noticeably
to the minor changes I made. Adjustments to
droop and ride height are simple to overlook,
but critical to carpet racing. I spent most of my
testing time fine-tuning these settings, which
resulted in faster lap times. XRAY includes
a copy of its comprehensive 40-page setup
book for the T2 platform. Using photographs
and illustrations, this manual explains many
of the possible adjustments and handling
xray
characteristics of the car in great detail. It’s
a great resource to all racers and adds a lot
of overall value to XRAY kits. And if that’s
not enough to fulfill your bench racing
daydreams, there are also countless
user-generated set-up sheets posted on
their website.
Rating: 9
Conclusion
XRAY’s latest ‘009 US Foam-Spec
edition kit continues the tradition that
XRAY has already established for its
T2 platform: top-shelf components,
perfect fit and finish and infinite
adjustability. Combine this with the
included setup book and the array
of online setup sheets, and the ‘009
US edition is poised for club races or
national championships.

POWERPLANT INFO
T
he Trinity Pulse 4.5 motor provided plenty of power with a very
smooth and useable power band. Combined with the Trinity
IP 3800 35C LiPo, top speeds were very fast, especially on what
are typically tight and small carpet tracks. Be sure to choose your
gearing carefully, as this decision is influenced by tire diameter,
motor and/or ESC timing, as well track size. Brushless motors
perform most reliably and consistently if kept under 175-180
degrees maximum, and the Pulse 4.5 is no exception.
