spec ifi c deta il s ofa certain step in the assemb ly .
& IM PORTANT NOTE: Even if you are familiar wi lh
T ea m Losi kits, be sure and pa y attention to these notes. They
point out very importantdetails during the assembly process. Do
not ignore these not es!

KIT/MANUAL ORGANIZATION
The kit is composed of different bags marked A through G. Each
ba g conrains all of the parts necessary to complete a particular
sec ti on of the Graphite Plu s'CR'. Some of these bags have s ub as-
sembly bags within them. It is essential that you open only one
bag at a
tim e and follo w the corre ct assembly sequence, other i
wise you may face diffi cu lti es in finding the correctpart. It is helpf ul
to read through the instructions for an entire bag prior to b f.'!-'111
ningasse mb ly. Ke y nu mb ers ( in parenthesis) have been a ss i ~ p wd
to each partand remain the same throughout themanual. In soml
illustra ti on s, parts which havealready been installed ar e not sho'' n
so that the current steps can
be illustrated more cl ea rl y.
For your conven ie nce, an actual -s iz e hardware id entifica
tion guide is included with each ste p. To check a part, hold it
against the silhouette until the correct p:m is identified. In som t'
cases extra hardware has been s up p li ed for parts that may b l'
easy to lose.
Th e molded parts in the Grapltit e Plus 'CR' arc manufac·
lured to demanding tolerance s. When screws are tightened to lhe
point of being snug, thP p art..., art> held firmly in plac e. For th is
reason it is very im portant that sc rews not be overtightened in
any ofthe plastic parts.
To insure that parts are not lost dur ing construction, it is
recommended that you work overa towel or marto pr event pan s
from rolling away.
IMPORTANT SAFETY NOTES
l. Select an area for assembly thatis awa y from the reach of
small children. Th e pa r is in th ekit are small and can be swallowed by
clzildretz, c ausing choking and po ss ib le inl ema l injury .
2. The shock fluid a nd greases supplied should be kept out
of c hi ldren's reach. Th ey are not intended for human consumption.'
3. &ercirecarewhen using any hand tools, sharp instrument s,
or power tools during construction.
4. Ca refull y read all manufacturer's w arnin gs and c autions for
any glues, chemicals, or paints that may be used for assembly and
operating purposes.

TOOLS REQUIRED
Team Losi has supplied all necessary Allen wrenches and a special wrenches that are needed for assembly and adjustments.
followi ng common tools will also be r eq uired: Need le-nose p li ers, regularpliers, hobby knife, scissors or other body cutting /t ri m
tools,
and a so ldering ir on may be necessary for radio installation. 3/ 16", 1/4", and 3/8" nut drivers are optional.
RADIO/ELECTRICAL
A suggested radio l ayout is provided in this manual. Your high-perfotmance RIC center sh ould be consulted regarding spec ifio oo
radio/electrical equipment.
HARDWARE IDENTIFICATION
When in question, use the hardware identification guide in each step. For screws, the prefix number designates the sere" in.> .v>d
numbe r of threads per inch (i.e., 4- 40 is #4 screw with 40 threads per inch). The second number or fraction designates the length
the screw. For cap- head screws, this number refers to the length of the threaded portion of the screw. For flat-head screws. tht numbr.r
refers to the overall length of the screw. Bearings and bushings are referenced by the i ns ide diameter x outside diam et er !wits and
pins are diame ter x length. Washers arc described by ins id e diameter or the screw size that will pass through the ms1de d....une<n
E-clips are sized by the shaft diameter tha t they attach to.
MOTORS AND GEARING
T he D oub l e· XT 'CR' Graphit e Plus includes an 88 -tooth, 48 -pitch spur gear . The overall internal drive ratio of the Graphite Pl us 'C R'
is 2.61: I. The pinion gear thatis used will det e rmine lhe final dr i ve rat io.To calculate the final drive ratio, fir st di, ·ide the spur gear size
by the pinion gear size. For examp le, ifyou are using a 20 -tooth pinion gear, you would divide 88 ( spur gear s iLe b: 10 (pinion gear
size).
88 /2 0 =4.4. This tells you that 4.4is the external drive ratio. Next, multiply the internal drive ratio ( 2.Ci I by the external drive
ratio (in this case
4..4) . 2.67 x 4.4 = 77.484. Th is means that by using a 20 -tooth pinion gear with the standard 88-tooth sp ur gea r, the
final
dt;ve ratio is 11.481 1: l.
Consult your high-performance shop for recommendations to suit your racing style and class. Th e chan below lists some of t he
more common motor types and a recommended initial gearing for that motor. Ratios can be adjusted depending on various track
layouts, tire sizes,
and bat t ery types.
