8IGHT T Instruction Manual Part 1 - Team Losi Racing

STEP I-01
Intro to the 8IGHT-T Manual
INTRO
Welcome Team Losi 8IGHT-T Owner!
Thank you for selecting the 8IGHT-T as your new racing truggy. The 8IGHT-T has already distinguished itself as a top caliber racing
chassis and as you will see, we have made every effort to produce a chassis that is not only the most competitive but due to the race ready
roller concept, also easy to use and maintain. Since building time has been greatly reduced you can get on the track sooner and concentrate
on the finer points of the set-up covered in the tuning tips. Before you start to install the radio and engine in, read through the instructions to
insure that your 8IGHT-T runs up to it’s full potential from the first second it hits the track. The simple bag-by-bag assembly sequence and
easily followed instructions and drawings combined with Team Losi’s world famous quality fitting parts will make building the 8IGHT-T a
most enjoyable project.
Before you open the first bag, or start assembly, please take a moment to read through the following instructions. This will familiarize
you with the various parts, assembly tips, and descriptions as well as the tools needed. Taking an extra moment before starting can save a
good deal of time and assure proper assembly.
Good luck and good racing,
Team Losi

Table 1: 8IGHT-T Completed Kit Specifi cations.
Kit/Manual Organization:
The kit is composed of different bags marked A through H. Each
bag contains all of the parts necessary to complete a particular section
of the kit. Some of these bags have sub-assembly 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 instructions
for an entire bag prior to beginning assembly. Next to each of the step
numbers is a check box. At the completion of each step, place a check
in this box so that if you must stop and come back to the assembly,
you will be able to pick up where you left off.
For your convenience, an actual-size Hardware Identification
Guide is included as a fold-out page at the back of this manual. Hardware
that is not easily differentiable in each step is called out with
an icon which contains a small
picture of the part genre (referenced
on the Hardware Identification
Guide), the quantity of
that part required for what is
shown in the step, and the size
or name of that part. To check a part, hold it against the silhouette until
the correct part is identified. Associated with each of these parts, in
the Hardware Identification Guide, is a LOSA-Number which is used
when ordering replacement parts for your 8IGHT-T. In some cases,
extra hardware has been supplied for parts that may be easy to lose.
Components used in each step are identified by their relative
LOSA-Number and the component’s name. With the exception of
a few parts, these are not referenced in the Hardware Identification
Guide.
The molded parts in Team Losi kits are manufactured to 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.
In some steps there will be a filled black circle with a white
number. These indicate the specific order by which assembly must
occur. In cases where steps are repeated (front/rear or left/right) these
numbers may be omitted. Please note that these numbers will not call
out every sub-step required for the step’s assembly procedures, they
will only highlight the critical order required for assembly.
In each step, there are specific “Detail Icons” (shaped like a stop
sign) that call out critical precautions or assembly tips for the process.
There is a reference key that describes the meaning of each of
the icons located on the fold-out Hardware Identification Guide at
the back of this manual.
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;
PLEASE USE CAUTION!
2. The shock fluid and greases supplied should be kept out of children’s
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 manufacturer’s warnings and cautions for any
chemicals, glues, or paints that may be used for assembly and
operating purposes.

TOOLS REQUIRED FOR ASSEMBLY
Team Losi has supplied all necessary Allen wrenches and a special wrenchs that are 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, and a
soldering iron may be necessary for radio installation. 3/16”, 1/4”, 5/16”, and 11/32” nut drivers are optional.
RADIO/ELECTRONICS
A suggested radio layout is provided in this manual. Your high performance R/C center should be consulted regarding specific questions
pertaining to radio/electrical equipment.
HARDWARE IDENTIFICATION
When in question, use the Hardware Identification Guide at the back of this manual.
• For screws, the prefix number designates the thread size and number of threads per inch (i.e., 4-40 is a #4 size thread 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 and set screws, this number refers to the overall length of the screw.
• Bearings and bushings are referenced by the inside diameter (I.D.) x outside diameter (O.D.).
• Shafts and pins are designated by type (Roll, Solid) and referenced by diameter x length.
• Washers, Spacers and Shims are described by inside diameter or the screw size that will pass through the inside diameter x the thickness
or by their designated application (i.e., Ball Stud washer is primarily used under a Ball Stud).
• Retaining Clips are sized by the shaft diameter that they attach to or by type (Body). The Hardware Icon associated with E/C-Clips only
designates the part genre of clips, not the actual part.
• Nuts come in four types, Non-Flanged, Flanged (F), Plain, and Locking (L) (designated on the Hardware Icons). The prefix number designates
the thread size and number of threads per inch. The second number, or fraction, designates the size of the hex. For example, L 4-40
x 1/4” designates a Lock nut that will thread onto a 4-40 screw using a 1/4” nut driver.
• Setscrews come in three types, Cup (C), Flat (F) and Oval (O) (designated on the hardware Icons). The prefix number designates the thread
size and number of thread per inch. The second number, or fraction, designates the length of the threade portion of the screw.
