NOTES & SYMBOLS USED
This is a common step number found at the beginning of each
new illustration throughout the manual.
q1. Each step throughout the entire manual has a check box to the
left of it. As you complete each step, mark the box with a check. If you
need to take a break and return to building at a later time you will be
able to locate the exact step where you left off.
This is a common note. It is used to call attention to specific
details of a certain step in the assembly.
IMPORTANT NOTE: Even if you are familiar with Team
Losi kits, be sure and pay attention to these notes. They point out
very important details during the assembly process. Do not ignore
these notes!
In illustrations where it is important to note which
direction parts are facing, a helmet like this one will be included in the
illustration. The helmet will always face the front of the car (as the
driver would sit). Any reference to the right of left side will relate to
the direction of the helmet.
The kit is composed of different bags marked A through H. Each
bag contains all of the parts necessary to complete a particular sec-
tion of the XXX-S. Some of these bags have subassembly bags within
them. It is essential that you open only one bag at a time and follow
the correct assembly sequence, otherwise you may face difficulties
in finding the correct part. It is helpful to read through the instruc-
tions for an entire bag prior to beginning assembly. Key numbers (in
parenthesis) have been assigned to each part and remain the same
thoughout the manual. In some illustrations, parts which have al-
ready been installed are not shown so that the current steps can be
illustrated more clearly.
For your convenience, an actual-size hardware identification
guide is included with each step. To check a part, hold it against the
silhouette until the correct part is identified. In some cases extra
hardware has been supplied for parts that may be easy to lose.
The molded parts in the XXX-S are manufactured so that they
interlock. When screws are tightened to the point of being snug, the
parts are held firmly in place. For this reason it is very important that
screws not be overtightened in any of the plastic parts.
To ensure that parts are not lost during construction, it is recom-
mended that you work over a towel or mat to prevent parts from
rolling away.
1. Select an area for assembly that is away from the reach of small
children. Some parts in this kit are small and can be swallowed by
children, causing choking and possible internal injury.
2. The shock fluid and greases supplied should be kept out of
childrens' reach. They are not intended for human consumption!
3. xercise care when using any hand tools, sharp instruments,
or power tools during construction.
4. Carefully read all manufacturers' warnings and cautions for
any glues, chemicals, or paints that may be used for assembly and
operating purposes. When you are using glues, chemicals, and paints
you should always wear eye protection and a mask.

TOOLS REQUIRED
Team Losi has supplied all necessary allen wrenches and a special assembly wrench that is needed for assembly and turnbuckle adjustments.
The following common tools will also be required: Needle-nose pliers, regular pliers, medium grit sandpapper, hobby knife, scissors, and body
cutting/trimming tools. A soldering iron may be necessary for electrical installation. 3/16", 1/4", and 11/32" nut drivers are optional.
RADIO/ELECTRICAL
A suggested radio layout is provided in this manual. Your high-performance R/ center should be consulted regarding specific questions
pertaining to radio/electrical equipment.
HARDWARE IDENTIFICATION
When in question, use the hardware identification guide in each step. For screws, the prefix number designates the screw size and number of
threads per inch (i.e. 4-40 is #4 screw with 40 threads per inch). The second number or fraction designates the length of the screw. For cap head
and button head screws, this number refers to the length of the threaded portion of the screw. For flat head screws, this number refers to the
overall length of the screw. Bearings and bushings are referenced by the inside diameter x outside diameter. Shafts and pins are referred to by
diameter x length. Washers are described by inside diameter or the screw size that will pass through the inside diameter. E-clips are sized by the
shaft diameter that they attach to.
MOTORS AND EARIN
The XXX-S includes an 90-tooth, 48-pitch spur gear. The internal drive ratio of the XXX-S is 1.83. The pinion gear that is used will determine
the final drive ratio. To calculate the final drive ratio, first divide the spur gear size by the pinion gear size. For example, if you are using a 20-tooth
pinion gear, you would divide 90 (spur gear size) by 20 (pinion gear size). 90/20 = 4.50. This tells you that 4.50 is the external drive ratio. Next,
multiply the internal drive ratio (1.83) by the external drive ratio (in this case 4.50). 1.83 x 4.50 = 8.235. This means that by using a 20-tooth pinion
gear with the standard 90-tooth spur gear, the final drive ratio is 8.235:1.
onsult your high-performance shop for recommendations to suit your racing style and class. The chart below lists some of the more
common motor types and recommended initial gearing for that motor. Ratios can be adjusted depending on the various track layouts, tire sizes,
and battery types.

q1. Insert all of the parts that are stacked on the Wrench (159) into
the Male Plastic Outdrive (7) (the one with the post). Line up the tabs
on the Diff ut (2) with the slots in the Outdrive. Press the parts all
the way into the Outdrive.
q1. Apply a small amount of Clear Diff Grease (8) to the outside
ring of the Male Plastic Outdrive (7). Attach a Diff Drive Ring (10) to
the Outdrive by lining up the flat section of the Ring with the flat
section on the Outdrive.
*NOTE: Only a small amount of Grease is needed. It is only
used to hold the Drive Ring in place.
Figure 4
IMPORTANT NOTE: Do not glue the Drive Rings to the
Outdrive/ Diff Halves. Doing so may not allow the Rings to mount
flat.
STOP! There are two, complete differential assemblies in the -S Graphite Plus kit. Both Differentials are identical front and
rear. Proceed through the Bag A instructions twice - once for the front differential, and once for the rear differential. The -
S kit was designed using the stock 42T drive pulleys in the front and rear of the car. There is an optional 41T pulley included in
Bag H of this kit, This feature can be used to apply under-drive or over-drive in the vehicle. See set-up tips at the end of this manual.

q2. Apply a fairly heavy coat of Clear Grease (8) to the exposed
side of the Diff Balls (14) in the Diff Pulley (11) on the Male Outdrive
(7).
q3. While holding the Female Outdrive with Allen Wrench inserted,
carefully assemble it to the Male half.
q4. Make sure that the slot in the Diff Screw is lined up with the
slot in the Female half. While holding the Male Outdrive half, slowly
turn the Female Outdrive until the threads of the Diff Screw engage
on the threads of the Diff ut. Remove the pencil from the male half
and thread the two Outdrives together until the Screw just starts to
snug up.
q5. Tighten the Diff until the Pulley cannot be turned while both of
the Outdrives are being held firmly. Final diff adjustment should be
made after completion of the XXX-S.
When tightening the Diff, tighten the Screw a little and then
"work" the Diff a little. Then tighten the Screw a little more and
"work" the Diff again. Continue this until the Diff doesn't slip. This
ensures that the parts in the Diff are properly seated. Refer to tech
tips for final adjustment. "Working" the Diff is done by rotating the
Outdrives in opposite directions.
