INTRODUCTION
Thank you for purchasing a Traxxas Nitro 4-Tec Pro.
This limited-edition, pro kit is loaded with all the latest
sedan racing hardware and engineering technology.
This pro kit does not come with an engine or tuned pipe,
allowing you to choose an engine which is legal for your
race track. If racing regulations do not limit you to a .12
size engine, then install the TRX Pro .15 engine for fast,
asphalt-blistering excitement. The Nitro 4-Tec Pro features
dual adjustable pro ball differentials smoothly distribute
the power to each corner of the car. Handling is quick
and precise with fully-independent suspension and tune-
able, oil-filled, pro-level, aluminum Big-Bore shocks.
Nitro 4-Tec Pro kit includes a two-speed, auto-shifting
transmission; full ball bearings; Lunsford™ titanium hinge
pins and turnbuckles; Perfect-Fit™ blue-anodized, aluminum
header; Pro-Line™ V-Rage™ tires; 2.0" aluminum finish,
mesh wheels; and graphite chassis components.
This manual covers the assembly and tuning process
for the Nitro 4-Tec Pro kit. Look over this entire manual
and examine the Nitro 4-Tec Pro carefully before
assembling it. If for some reason you think the Nitro 4-
Tec Pro is not what you wanted, then do not continue
any further. Your hobby dealer absolutely cannot accept
a Nitro 4-Tec Pro kit for return or exchange after any of
the kit bags have been opened. If you have any ques-
tions about your new Nitro 4-Tec Pro, call Traxxas' tech-
nical support department at (888)TRAXXAS (U.S.A. res-
idents only). Outside U.S.A. call 972-265-8000.
Technical support is available Monday through Friday,
from 8:30 AM to 5:30 PM Central Time. You may also e-
mail us at our website, www.Traxxas.com. We hope that
you will enjoy your Nitro 4-Tec Pro race car.
ASSEMBLY HINTS
To assemble this kit, you'll need a large flat working area
where you will have plenty of room to build. Be sure it is
some place where you can leave your work spread out
and not in the way when you want to take a break from
the assembly. Allow yourself plenty of time to build this kit.
The assembly time is going to vary with each individual.
Experienced builders may only need 4 - 5 hours to assem-
ble this kit, while others may spend an entire weekend on
it. You should feel comfortable with taking as much time as
you need to properly build and set-up your model. The
race, after all, is on the track, not the workbench.
If you have already been exploring the contents of
your kit box, you've noticed that there
are many bags of small
parts. A parts box has
been provided with your
kit to keep all of these
small parts organized and
easily accessible. As you
open a bag of hardware,
use what you need and
pour the remainder in one of the compartments. The
compartments are labled in procession with the assembly
step numbers. Some extra hardware may be left over
when the car is assembled.
