1988 ROAR NATIONAL
CHAMPION I
Congratulations! You have now joined
the wonderful world of RIC racing. Many hours of
fun are ahead of you. The PR0-1 0 SPORT you
have purchased is based on the nationalwinning
design
of the PR0-10 ELITE, one of the top 1110th
scale T-bar oval and on road cars in the world.
Two
of the most successful radio controlled car
manufacturers in the world,Co mposite c raft and
TRC ha ve joined forces and have in troduced an
entry level racing machine at an entry levelprice
without sacrificing race performance. The
PR0-
10 SPORT can take you from the beginning all
the way to the top.
As
you r skill level increases, t he PR0-1 0
SPORT can be up-dated to improved perform-
ance and will be readyto handleanything you can
give it. The
PR0-1 0 series of cars are still the
most simple cars to b
uild and maintain on the
circuit. Precision molded
and machined compo-
nents make the PR0-10 SPORT a snap to put
together, but you still need to read and follow the
instructions. Theywill
give you tips in the assem-
bly process that w ill help you when it is time to
race.
TAKE YOUR TIME I How careful you
assemble the car now is going to determine how
well it performs on the track. Don't be in a hurry.
You won't win anything
for the fastest chassis
assembly.

• THE FACTORY •
•• •• • •••• •••• ••••• • •••
Before you get started, here are some
suggestions
and tips that w ill make the assembly
of your kita little easier.
Glance through the instructions and
picturesoncebefore you startto assemble the kit.
This will help
get you familiarized with the
assemblysteps
and the p ic tures.
2
To help eliminateconfusion, only open the
partsbags when they are calledfor in the instruc-
tions. Otherwise you might mix up small parts
which willmake the assemblymuch more difficult.
When
you empty the parts bags, use a
paper plate or a small containerto empty it in. This
will keep parts from rolling off t he table and being
lost foreve
r.
When you are putting screws into plastic
pieces, be sure that
you do not over tighten them.
This
could result in t he threads in theplasticstrip-
ping. Tighten the screws untilt hey are snug.
Check
all the hol es in t he nylon pieces.
Some of the holesare no t tapped. You should tap
these holes with the correctsize tapbeforeputting
a
screw in the piece.
All molded nylon pieces will have a small
amount of flashing. Before you assemble these
pieces
it is a good idea to remove it with a hob by
knife. In the instructions, certain parts are
referred to as left
and right. Imagine yourself sit-
ting in a full size car in the driver's seat. The
driver's side
is what will be referred to as t he le ft
side. The passengerside w ill be referred to as the
right side. Please keep this in
mind while you are
assembling
your car.
The step numbers
in this manual corre-
spond to t he pictur es in the pic torial assembly
manual. Use both
for the assemblyof this kit.
Due to COMPOSITECRAFT & TRC's
on-going development program, certain parts in
the pictorial assembly
manual may be different
from the actual
parts in the k it.

Checkthe contents of each bagwith the list above.
These bags have been checked at the factory, but it
is
possible that a part may be missing. For missing parts call
704 - 982 -0507. Make sure you use part numbers when
ordering.
ONE FINAL NQTE I
Assemblystep numbers correspond to the
picturenumbers. Complete eachstepbeforegoing
on to the next.
NOW LET'S GETSTABTED I

STEP# 1 We will needto do a slight amount
of chassisprepbefore we startthe assembly.
Locate the chassis,
and you will notice that on one
side the holes in the chassis are countersunk for screw
heads. This is the bottom
of the chassis. On the top of the
chassis
we want to file the batteryslots at a slightangle so
the batteries will not
be sitting on a sharpcornerthat could
cut the protective heat shrink
on them and cause them to
short out. Lightly file both the front
and back of all the
batteryslots so the cells willhavea flat spotto sit
in. Before
you do this, itmight
be a good idea to spreadsome newspa-
per out to catch the filings. You will also use strapping tape
to holdthe batteries in the chassis. You will needto file the
sections
of the chassis that the tape goes around. If these
placesare leftsharp, theywill
cut the tape and the batteries
willfallout. Just round
off these edges.
When you are finished, wash
off the chassis with
water
and dry it off witha paper towel.Then make sure you
wash your hands with soap
and water. Clean up the dust
anddispose.
You are now finished with step #1. Put a check
mark in the box to show that this step is complete. After
you've completed each step from nowon, check
off its box
soyou know which part
of the assemblyyou are on in case
of an interruption. You won't miss anysteps this way.
PR0-10 SPORT FRONT
END ASSEMBLY
STEP# 2 Open bag #1 and empty the
contents.
For the time being do not open bag #1A. Locate
thefrontnyloncross
bar .Checkoverthe beamto makesure
all the flashing,
if any, is removed around the holes. The
caster on this front end is 0 degrees. This means the king
pins will
be straight up and down. You need to run a small
amount
of caster in the front end, so locate the two caster
shims. These are molded
at 2 degrees each. Fasten the
frontbeam
to the chassiswith the castershims betweenthe
chassis
and the frontbeam. Use an 8-32x 112" screw in the
front
and a 4-40x 114" screwin the rear of the beamblock.
Tighten
all screwscompletely.
STEP# 3 Locate the two front steering
blocks
and remove any flashing from around the holes
with a hobby knife.
STEP# 4 Locate the two front kingpins. You
will notice that they have a groove in each end. These
groovesarefor
thee -clips. Putonee-clip on one end of each
kingpin.
STEP# 5 Next,
put a king pin in the bottom
arm on the front cross
bar so it sticks through about 118".
Now slide a steering block on the king pin as shown and
push the king pin up until it reaches the top of the steering
4
block and sticks throughabouta 1116". There is nota leftor
a right
on the steeringblocks. Theyarethe same. Nowputa
spring
on the king pin on top of the steeringblock, then a
thick washer
and push the king pin through the top of the
axle beam. Put an e-clip in the top groove
to hold the
assembly inplace.
STEP# 6 Open bag #1A. Findthe frontbody
posts. Fasten them to the chassis using the 4-40 x 1/2"
screws. Holdthepostswithplierswhiletighteningthescrews.
Make sure you do notovertighten the screws
and strip out
the threads. Put the body
post collars on the posts just
underthelastset
of hood pin holes and lockinplacewiththe
4-40 x 118" set screws. These will be adjusted laterto the
body.
STEP# 7 Putthe seNomountingpostsin the
chassis
as shownusinga 4-40x 114" screw. For now, put the
seNo mounting face plates on the posts with the
#2 X 318"
selftap screws so theydo not get lost These will hold the
steeringseNo in placelater.

REAR T-SAR ASSEMBLY
STEP# 8 Open bag #2 and locate the steel
pivotball and the 114" steelwasher. Fasten thepivotballto
the t-bar in the middle hole with the washer in between the
pivot ballandthe t-bar
as shown using a 4-40x 114" screw.
It would be a good idea to lock lite this screw. Do not use
pliers to holdthe ball while tightening the screw.
STEP# 9 Find the pivot ball nylon socket.
Using a lightoil, coatthe inside
of the socketthatsnapsonto
thepivotball
as well as the pivotball. Snapthepivotsocket
onto the pivotball. Move it around.
It willprobablybe a little
tight. Afterthe
car hasbeenruna few times itwillloosen up.
STEP# 10 Next, findthetworearmotorblocks.
Fasten them to the rear t-bar using four 8-32 x
112"
aluminumflatheadscrews. Note:bothmotorblocks are the
sameshape. The
only difference is in the holes for the ride
height adjustors. Be sure to
put the blocks on the t-bar so
the rideheightadjustors will
be on theoutside of theblocks.
Not
on the inside.
STEP# 11 Now find the ride height adjustor
set. You will notice that there are three different offsets in
them. This gives you the option
of five different rear axle
heights, depending
on how they are placed in the motor
blocks. Most
of the racers run the axlein the middle setting,
butyou can referto the section
on RIDE HEIGHTSET UP.
When you have chosen the set you are goingto use, install
them in the motorblocks
as shown. Be sure to trim off any
flashing that might
be presentaroundthe edges.

STEP# 12 Next, fasten the motor blockbrace
to the motorblocks, using four 5-40 x 114" capscrews and
the 8-32 X 318" screws.
Put the brace on so that the TRC
logo
is facing up andto the rear of the t- bar as shown_
