NOTES & SYMBOLS USED
Figure 1
This is a common figure number found at the beginning of
each new illustration throughout the manual.
! Step 1. - 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.
*NOTE: 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!
! This wrench designates a performance tip. These tips
are not necessary, but can improve the performance of your
Triple-XT truck.
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.
Any reference to the right or left side will relate to the direction of
the helmet.
demanding tolerances. 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 recommended that you work over a towel or mat to prevent parts from
rolling away.
IMPORTANT SAFETY NOTES
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. Exercise 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.
KIT/MANUAL ORGANIZA TION
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 Triple-XT Sport are manufactured to

TOOLS REQUIRED
Team Losi has supplied all necessary Allen wrenches and a special wrench that is needed for assembly and adjustments. The following
common tools will also be required: Needle-nose pliers, regular pliers, hobby knife, scissors or other body cutting/trimming tools.
3/16", 1/4", and 3/8" nut drivers are optional.
RADIO/ELECTRICAL
The XXX-T Sport's radio layout is well proven. Your high-performance R/C center should be consulted regarding specific questions
pertaining to radio/electrical equipment changes.
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 GEARING
The Triple-XT Sport includes an 88-tooth, 48-pitch spur gear. The overall internal drive ratio of the Triple-XT is 2.43:1. 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 88 (spur gear size) by 20 (pinion gear size).
tells you that 4.4 is the external drive ratio. Next, multiply the internal drive ratio (2.43) by the external drive ratio (in this case 4.4).
2.43 x 4.4 = 10.692
10.692:1.
Consult 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 a recommended initial gearing for that motor. Ratios can be adjusted depending on various track
layouts, tire sizes, and battery types.
. This means that by using a 20-tooth pinion gear with the standard 88-tooth spur gear, the final drive ratio is
88/20 =4.4

Step 1. Place the servo saver bottom (1) over the servo saver
!
post (2) and slide the servo saver bottom all the way against the
hex at the opposite end. Be sure that the hex on the servo saver
post (2) is inserted into the hex in the servo saver bottom (1).
! Step 2. Slide the servo saver top (3) down over the servo
saver post (2) so that the 'V' area of the servo saver top (3) rests in
the 'V' area of the servo saver bottom (1). The arm on the servo
saver top (3) and the arm on the servo saver bottom (1) should
point in opposite directions as shown in Figure 1.
! Step 3. Slide the servo saver spring (4) over the servo saver
post (2) and push it into the recessed area of the servo saver top
(3). Install the servo saver spring cap (5) and thread the 6-40
locknut (6) onto the end of the servo saver post (2).
! Step 4. Tighten the 6-40 locknut (6) all the way down and
then loosen it two full turns (e.g. 360o x 2). This is a good starting
point for the adjustment. Once assembly is complete, if you wish,
the servo saver can be adjusted tighter or looser.

in the servo saver bottom (1) and steering idler arm (8) as shown
in Figure 2. Thread a 3/16" ball stud (11) through the outside
hole in each arm, into the nuts (7), and tighten. Insert a 4-40 mini
locknut (7) into the hex area in the servo saver top (3). Thread a
3/16" ball stud (11) through the hole in the arm, into the nut (7),
and tighten.
! Step 6. Insert a 4-40 mini locknut (7) into the hex areas in
the rear of the servo saver bottom (1) and the steering idler arm
(8) as shown in Figure 2. Thread a 3/16" ball stud (11) through
the arms, into each nut (7), and tighten.
! Once assembly of your new Triple-X is complete, you
may notice that the tires toe in slightly as the suspension compresses. We have found this setting to yield the best performance.
Should you prefer to change this so that the tires do not toe in,
you can add one ball stud washer under the ball studs on the
outside of the servo saver assembly and steering idler arm. To
accomplish this, you will want to replace the 3/16" ball studs
with 1/4" ball studs.
