Any reference to the right
or left side will relate to the direction of
the helmet.
KIT/MANUAL ORGANIZATION
The kit is composed of different bags marked A through H. Each
bag contains all of the parts necessary to comp lete a particular
sect i on of the Street Weapon. Some of these bags have subassem-
bly bag s wi thinthem. Tt is essential thatyou open only one bag at
.
l
a time and foUow the correct assembly sequence, otherwise you
may face difficulties in finding the correct parL [t is helpful to
read through the instn1ctions for an entire bag prior to beginning
assembly. Key
numbers (in parenthesis) have been assigned to
each part and remain the same throughout the manual. In some
illustrations, pariS which have already been installed are notshown
so that the current steps can be iUustrated more clearly.
Foryour convenience,
an actual size hardware identification
guide
is included with each step. To check a part, hold it ag-,linst
the silhouette until the correct pan is identified. In some cases
extra hardware has been supplied for parts that may be easy to
lose.
The molded parts in the treet Weapon are manufactured to
demanding tolerances. When screws are tightened to the point of
being snug, the parts arc held firmly in place. For this reason it is
very important that screws not be overtightened in any of the
plastic parts.
To insure that parts are not lost during construction, it is rec·
ommended that you work over a towel or mat to prevent parts
from rolling away.
IMPORTANT SAFETY NOTES
I. Select an area for assemb ly that is away from the reach of
small children. The parts in the kit are small and can be swallowed by
childrm, causing choking and possible intemal injury.
2. The shock Auid and greases suppliedshould be kept out of
children's reach. 1l1ey are not intended for human consumption!
3. Exacise care when using any hand tools, sharp instruments,
or power tools during construction.
4.
Carefully read allmanufoctum's warnings and cautions 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 specialwrench that is needed for assembly and adjustments. Th e follow-
ing common lOols will also be required: Needle-nose pliers, regular pliers, hobby knife,scissors or other bodycutting/trimmingtools,
and a solderingiron may be necessary for radio installation. 3/ 16 ", 1/4'', and 3/8" nuldrivers are optional.
RADIO/ELECTRICAL
A suggested radio layout is pro~ided in this manual. Your high-performance RIC center should be consulted regarding specifics on
radjo/electricaJ equipment.
HARDWARE IDENTIFICATION
When in question, use the hardware identifi cat ion guide in each step. For screws, th e pr er lX nwnber designates the sc rew size and
numb erofthreads per in ch (i.e. 4-40 is #4 screw with 40threads per inch).Thesecond number or fraction designatesthe length ofthe
screw. For cap-head screws, this number refers lo tl1 e length of the threaded portion of th e screw. For nat-head screws, thi s number
refers to th e ove rall length of the screw. Bearings and bushings are referenced by the inside diameterx outside diameter. Shafts and
pins are diameter x length. Washers are described by insi
de iliameter or the screw size that will pass through th e inside diameter.
£-clips are sized by the shaft diameter that they attach to.
MOTORS AND GEARING
The Street Weapon includes a 78-tooth, 48-pitch sp ur gear. The overall internal drive ratio of the Street Weapon is 2.3: I. The pinion
gearthat is used will determine the final drive ratio. To calculate the final drive ratio, first divide the spurgearsize by the pinion gear
size. For example, tf you are usmg a 20-tooth pinion gear, you would ruvide 78 {spur gearsize) by 20 (pinion gear s i :~:e ) . 78 120 = 3.9.
Thjste ll s you that 3.9 is theexternal drive ra ti o. Next, mult ipl y theinternaldrive ratio (2.3) by the external drive ratio (in this case 3.9).
2.3 x 3.9 = 8.97.This means that by using a 20-too th pinion gear with the standard 78 -toolh spw ·gear, the final drive ratio is 8.97:1.
Consult your high-performance shop for reco mm endations to sult your racing style and class. The chart below li sts some of ili e
mor e common motor ty pes and a recommended initial gearing fo r t ha t motor. Ratios can be ad ju sted depending on va ri ous track
layouts, tire size:., and battery types.
