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.
PR0-10 SPORT
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_

done so far.
(DIFFERENTIAL ASSEMBLY )
STEP# 27 Locate bag #5 and empty into a
container. There are many small parts that will roll off a
table in this bag. Find the diffaxle. Slip one
of thediffdrive
rings onto the hubonthe axleasshow
n. Many racersuse a
drop
of superglue, like ZAP or HOT STUFFtoholdthedrive
ring inplaceon the hub.
STEP# 28 Now locate the spur gear . You will
notice t hat the gear has two sets of holes in it. We will be
using the outside set
of holes. Push an 118 "diffballin each
of theoutside eight holes. Now put a smalldab of diffgrease
on eachball.
STEP# 29 Now slide the spur gear onto the
diff ax le topped with the second diffdrive ring. If you find
something to stand the
diff axle in while building, it makes
assemblymuch easier.
STEP# 30 Next, push a nylon bushing into
each endof thediffhub. Besure
to trimanyflashingoff from
the edge of thebushings. Makesuretheyfit all the w ay down
in the hole. Put a drop
of light oil inside each bushingand
slidethehub assemblyonthe axle.Lineupthe drive ringon
t
op of thegear with the diff hub. This drive ring may also be
superglued
to the hub.
STEP# 31 Now put the thin thrust washer on
the axle, inside the
diff hub, followed by the black thrust
bearing,andthen thethick thrustwasher. Next, putthesteel
cone washeronthe axle
(small end up) andlastly the 8-32
nylon lock nut. Tighten the
nut just enough to hold all the
partsinplace. We willadjustitlater. Onlyuse a nylon nuton
thediff axle.
STEP# 32 Put the two 11 4" x 318" flanged
bushingsin theride heightadjustorsin the motorblocks. Put
a drop of light oilinside each bushing.
STEP # 33 Next, find the nylon axle spacers.
Take the
118" spacer and s li de it on the di ff axle. Slide the
assemblythrough the bearin
gs in the rear pod .

STEP# 34 On the otherside of the axle, slide
on theother 114 " spacer.
STEP# 35 Now locatethewheelhub and slide
it on the diff axle next to the nylon spacer. Using the two
10-32 x 11
4" set screws, lightly lock the hub into position
on the axle. Loosen t he screws and remove the wheelhub.
The screws have leftmarks
on t he axle. Lightlyfile a small
flat spot in the axle where the marks were made. This will
make
it easierto remove the w heel hub later on .Putt he hub
back on the axle, and check theside to side play . You only
want the axle to move from side to side about a piece of
papers thickness. Tighten the set screws on the flat spots
thatyou filed
on the axle. Spinthe axleto makesureitturns
freely.
STEP# 36 Install the rear tires on the rear
hubs using the eight 5-40 x
3/8" screws. Remove all the
flashing from around the screw holes
on the hubs or the
wheelswillnot
sit flatagainstthe hub .Also be sureto tighten
all the screwsequally, otherwise the wheelw ill not run true.
Spin the rear axle and see if the tires are running true. If
they arenot, loosen or tighten screwsuntiltheydo run true.
STEP# 37 To adjust the diff, turn the car so
the rear
end is facing you . Holdthe left hand tire in your left
hand
and the right hand tire in your right hand . No w with
your right hand thumb on the top of the spur gear, try to
rotate the

partsare in thecorrectposition. Now, on to theradio gear in -
stallation.
. (RADIO GEAR INSTALLATION )
There are a number of good radios on the market
today. Consult your hobby shop and theycan suggest the
best set
up for the type of racing you wiff be doi ng . Ifyou
plantodoa lot
of seriousracing, we recommendthat you do
not
buy the cheapest rad io possible. This could result in
radio interferenceproblems
at therace track.
There are manydifferentways to install radio
gear .
This is only one w
ay . Put the gear in the w ay that is best
6
suitedforyou and your type of equipment.
We will be showing you the installation of an elec-
tronic speed control. This is the most popular type speed
control device
used today. Although, resister type speed
controls are still avaifable,
you will hav"e much less trouble
from
an electronictype. There are manydifferent types and
price ranges to choose from.
Ask your hobby shop to help
you pick
one that willdo the job foryou.

and wheel that came on it.
Put
your servo saverinitsplace as shown, but donot put the
screw back
in. You need to use the servo saverwhenyou
race. W
hen you hitsomething,theservosaverhasa spr ing
in it that keeps the internal gears in the servo from being
stripped. That's w
hy they callita servo saver. Prettygood,
uh? Now, with your fingers, tum the servo saver all the way
to the left
and then all the way to theright to the stops. You
wanttopositiontheservosaversothatit's right in themiddle
of the stops. Now screw in theservo shaftscrew.
STEP# 40 Stick a piece of servo tape on the
bottom
of theservo. Only peel off oneside of theprotective
backing.
STEP II 41 Remove the screws and face
platesfrom the servo mountingposts
and positionthe servo
between the posts
on the chassis as shown. Be sure the
servo saver is in the middle
of the chassis. When you are
surethe servo is in the rightposition,
peel off the protective
backing
and place the servo on the chassis. Lockthe servo
in place (using the screws
and face plates) to the posts as
shown. Some servos are too large to fit in between the
servo mountingposts.
If yours will not fit, onlyuse one of the
posts. Remove the
post on the side that w ill still allow the
servosaverto
be in the center of thechassis.
STEP# 42 Now, put the steering finkage in the
servo saver
and steeringblocks as shown.
STEP# 43 Next, lock the two pieces of
steering linkage in place using the set collars and 4·40
set screw s. With theservosaverin the straight up position,
the front wheels should
be pointing straight. Adjust the
linkage untilthey are.
STEP# 44 Position your recei ver in the
position where the Novak receiver is shown. Attach it
to the
chassis using double sidedstickytape.

STEP# 45 Take the end of the receiver wire
and run
it up throughthebottomholein the antennamount.
Next, run theantenna wire up through the antennatube until
about an inch is sticking out of the top of the tube. Fold the
antenna wire
over the end of the tube and put theantenna
cap on to hold the wire in place . Take the excess receiver
wire and neatly fold it up and tie-wrap it along side the
receiver. Plug the steering servo wire into the appropriate
spot in the receiver.
STEP# 46 Mou nt your speedcontroldevice in
the position that the Novak speed control is shown on the
chassis. Attach
it to the chassis using double sided tape.
Plug the speed control's wire into the throttle spot on the
receiver. Nextusethedouble
sided tapeto attachtheswitch
to the chassis. Tie-wrap the steering servo
and speed
controlwires together in a neat bundle.
STEP# 47 Many different battery configura-
tions
can be used with the PR0-1 0 SPORT. This step wilf
showa 6 - cell pack for roadcourse racing. Using a piece
of wire or battery shunt wire, solder the batteries together
as shown. M ost of the racers glue the cell together before
soldering w
ith eithera hot glue gun or silicone cement. This
makesth
em mucheasierto w orl< with. All of theconnections
should
be positive to negative. Solder tabs can be made
from pieces
of wire or batteryshunt. The connections from
t
he speedcontrolcan be made to these instead of directlyto
the batteries each time. This protects the batteries from
being overheated too
many times. Next, cut a piece of
jumperwire. Thiswillconnectthetwo packs together. When
measuring the wire,
allow enough clearance for the wire to
clear the shock mount. The
jumper w ire length should be
about3 112· long. Solder the jumper wire into place and set
the pack in thechassis to make sure everythingis correct.
STEP# 48 Put the battery pack in the car and
use nylon strapping tape to hold the batteries in. About 2
wraps
of tape per side should do it. Now solder the speed
controlbatterywires to thebattery locations shown. Refer
to the
speed control instructions for the proper wire hook
ups.
STEP# 49 Install the motor in the rear pod.
Hook
up thewires fromthe speed controltothe correspond-
ingpositive and negative terminals on the motor.
The
spur gear suppliedis a 64 pitch gear. You wilf
needto get a 64 pitchpinion gear . The size pinion gear you
get wiffdepend on what motor you have and w hat type track
you
are racing on. Consult the motor manufacturer for
pinion gear size. After youhaveselecteda piniongear, put
it on the motor shaft and lock it in place with a 4- 40 set
screw. The edge of the pinion gear should be evenwith the
edge
of the spur gear. TRCI COMPOSITECRAFThasa full

To set the gear mesh, loosen the motor screws so

the motor can slide front to back. Pullthe motortoward the
rear axle untilthe pinion gear engages with the spur gear.
Youshould be ableto feel a small amount of play in the spur
gear. Tighten the motor screws and checkthe play again. If
the gear mesh is too tight, you will lose running time. If the
gears
are too loose they w ill strip out very easily.
If you run a large spur gear and pinion, it wiff be
necessary to file a
small amount of the t- bar away so the
motor
can be moved forwardenoughto get the propergear
mesh. This wiff
not hurt the strength of the t-baras long as
you don't
go too far. About 1116. should be enough.
This shouldcomplete the mechanical assembly
of
your PR0-1 0 SPORT . The body is next.
BODY PAINTING INSTRUCTIONS
Before you get started, you should decide on the
colors you
are going to use to paint the body. You should
usea paint that is
made for Lexanbodies. Many brands are
available
in spraycans as we ll as brushon.
Wash the inside
of the body using warm water and
soap.
Be sure to rinse the body good to remove all of the
soap.
Dry the body off completely with a soft, lintfree cloth.
Remove the antennafrom the chassis
and setthe
body on top
of the chassis. Line up the wheel wells in the
body to the wheels on thechassismakingsurethechassisis
centeredsideto sideinthebody. With a magic marl<er, puta
marl< on the body on top of the bodyposts. After youpaint
the
body you wilf be able to tellwhere to drilf the 1/ 4" holes
for the body posts.
Using maskingtape,
cover the windshields and any
other areas not to be painted with the first color. Rub the
edges around the tape with the back
of your finger naifso
th
at paintwiffnot bleed under the tape. Makesureyouusea
good automotive grade paint tape or the paint will bleed
through
it anyway.
After the body has been taped, spray or brush on
thepaint.
It is betterto paint severalthincoats as opposedto
one thickcoat. Ifyou are going to paint the body morethan
one color, the darl<ercolors should
be paintedfirst and the
lightercolors last.
If you paint thelight colors first, the darl<
colors wilf bleed through thelightcolors.
After the
paint has completely dried, remove the
masking tape from the windshi
eld and any otherplace you
may have taped. Trim the body along the bottom trim line
usinga
pair of scissors or a hobbyknife. Drilf a 114" hole in
each
marl< that you made for the bodyposts. Set the body
on the chassis. Checkthe height of the body. You cannow
raise
or lowerthe body post collarsto get the bodyto setthe
way you want
it on the chassis.
Using a magic marl<er trace around the front and
rear wheels
on the outside of the body. Trim out the wheel
whee
ls. If any magic marl<er is left on the body it can be
removed with rubbing alcohol.
Be sure to trim the wheel
wells about 114• larger than the wheels to allow for the
suspensionto move.

BEFORE YOU RACE THE CAR. TAKE A FEW
MINUTES TO READ THIS CHASSIS SET UP SECTION.
IT WILL GIVE YOU A PLACE TO START BEFORE YOU
GET TO THETRACK. BEFORECHARGING THE BAT-

PR0-10 SPORT CHASSIS SET UP
Here are some tips that our racing team uses and
some terms and explanations used in ric car set up. The
suggestions that are given in this manual are a starting
point.
The final set up you willhavewilldepend on your track
and driving styles.
When you makechanges to the chassis. onlymake
one or two changes at a time. If you make a bunch of
changes all at once. you won't know which one helped or
hurtthe set up for sure. Take your time and start off driving
slow
and work your way into it. It will take practice.
FRONT CASTER
Casteris a termreferring to the angle thatthe king
pins lay backcomparedto thechass is. As ageneralrule. the
more caster
you have ( the more the king pins are leaned
back) the lesssteering you will have at high speeds. The
car willalsohave morestabilitywith morecaster. The team
starts
out with 3 -4 degrees of caster.
To changecaster on the PRO-t 0 SPORT, you add
or subtract caster shims. Everytime that you add a caster
shim it lowers the chassis ground clearance. Keep this in
mindwhen addingshims. Each shim is two degrees.
TWEEKING THE CHASSIS
The wordtweek refers to how flat the chassis is. If
your chassis is notflat then it is tweeked. You must set the
tweek to insure the
car tums the same in bothdirections. It
must be donewhen the chassis is in a raceready state, less
the
body .
The tweekadjustments
for the PR0-1 0 are the two
outside screws that the rear suspension springs are on.
Holding the
car with the bottom of thechassis facing toward
you
and the front of the chassis pointing up. you will see
these twoscrews.Which everscrewyou tighten. itwillmake
the front wheel
on that samesideheavy and the rear wheel
on that side lighter. When you tighten these screws. do not
tightenverymuch
at a time. A fullturn on thescrewwillmake
a bigchange
on the tweek.
To check the tweek, set the chassis on a flat.
smooth surface with the front
of the car facing you. Using a
hobbyknife, lift thefront
of the chassis in the middle, about
t• off the surface and spin both of the front tires. Slowly.
lowerthe chassis
and both of thefront wheels should hit the
•
8
surface and stop at thesametime. In orderforthismethod to
work. both of the fronttires must be thesame size. and the
chassis must
be in race readystate less the body. If theydo
not touch at the same time. tighten or loosen the tweek
screws.
RIDE HEIGHT
The PRO-t0 has five different rear axle ride height
adjustments.
The purpose of these areto controltheground
clearance
of the chassis. and to adjust weight transfer.
If the rear of the chassis is higherthan the front of
the chassis. in respect to ground clearance. more we ight
will
be transfered to the front of the chassis. giving more
steering. The same holds.true
if the front is higherthan the
rear.
It w ill give you morereartraction.
Keep thechassis
as low as the track conditions will
allow. Do not set it up so that the chassis w ill bottom out
when the rearsuspension is
at full travel.
FRONT &REAR SPRINGS
The front springs that come in the PRO- tO kitare
.022·. You may want to trydifferent springs on the frontend.
As a generalrule. the softerthe spring. the more steering
you willhave.
If you arerunning an ovalwith most of the batteries
on the left side of the chassis. the left spr ing needs to be
stifferthan the right spring.
Regardless
of the springs that you use, you will
need todampen thesteeringblockswith a thicksiliconelube
to smooth it
out and keep itfrom bouncing.
The springs thatare suppliedinthe rearsuspension
should
be used . Stiffer and softersprings have been tried.
butthe stocksprings work well for
most tracks.
BATTERYPOSITION
The position of the batterypackplays an important
part in the way the chassis handles. The furtherforwardthe
pack is in the chassis. the more steering you will have.
The
furtherbackthepack is. themore reartractionyou willhave.
For 6-cellroad racing. the team runs three cells per
side. positioned
In the back three rear slots in the chassis.
Remember. Ifyou
need moresteering. move them forward
oneslot.
For6-cell
oval racing. the team runs 5 cells on the
leftside starting
at the rear and t cell on the right, one slot
back from thefront.
TIRESELECTION
The tires thatare suppliedin this kitaregreenfronts
and green rears. These tires willwork on 80% of the tracks
that you will be racing on. although
other tires might work

betterundercertain conditions.
For oval racing on banked oval tracks,
TIM
RADIALS should be used. These tires have won every
majorovalrace in 1989. There isno bettertire for this type
of racing.
Forracing on carpet, the green tires thatare sup-
pliedwillworkfine. Dependingon thecarpettype, YOKOMO
tires might work a little bitbetter. YOKOMO tires are avail-
able from TRC.
Forracing onasphalt, green tires are what most
of
the team uses. Because asphalt is different around the
country, this is something that you will have to experiment
with. Good handling is a balance between frontandrear
traction. You shouldalways
run thehardestpossible tirethat
gives you the traction that you need. Running a softer tire
will increase traction, butit will hop andslow the
car down
in the turns.
You canaddtraction withoutchanging compounds,
with theuse
of atractionadditive. Forinstance, if the carhas
good front traction but it is a little loose in the rear, traction
additivecan be addedto the reartires.
The following traction chart will give you the
traction
of eachcompoundunder normalconditions.

ADJUSTING THE REAR SHOCK SPRINGS
ThePR0-10SPORTis suppliedwith areardamper
that acts as a shock absorber for the rear
T-bar. By com-
pressing or looseningthe setcollars, the motion of T-barwill
be stiff or soft from front to back. ff the rear of the car is
bouncing, compress the springs. Be sure
to put a drop of
silicone lube In thehole thatthepushrodgoesthrough. The
springs suppliedwill work the best.
W INGS
Most racers today run wings at all types of races.
Wing selection isimportant to carhandling. Running a wing
will
do two things. It increases the rear traction andstability
of the car. It decreases front traction andadds drag to the
car. Run as small
of a wing as possible to give you the
results that you need. Running a huge wing will add too
much drag andslowyou down anddecrease yourrun time.
There are manydifferent types of wings available.
Do some testing and pick the one that suits your racing
best.

UP-GRADING YOUR PR0 -10 SPORT
The PR0-10 SPORT was designed as an entry
level race car.
The carmaybe racedin the stock form , but
there are many improvements that can be
made to the
chassisthatwillenhancethe performance
if youeverstartto
race ona competitivelevel. Because the PR0-10 SPORTis
basedon the same design as the PR0-10 ELITE, all
of the
ELITEparts willfit on your SPORT.
When you start to race, one of the most important
things toconsideris weight.
You want the car to beaslight
as possible.
The chassis.supplied is made from fiberglass.
One of the best we ight savings you can getis by putting a
graphite chassis on the car. This chassis will save you
almostone ounce overthe fiberglass chassis andit will
be
much stronger. The partnumberfor the graphite chassis is
#5310. Another area that you need
to look at in racing is
rollingresistance. Becausethe carisbatterypowered, ithas
a limited supply
of power. The more freely everything rolls
the less powerit
takes, which will make the car run faster
and longer.
The carcomes with oilite bushings. Replacing
these with ball bearings will free up the front and rear
wheelssoyou can
run fasterandlonger. The partnumbers
are #5480 & #5484.
When you crash the car at high speeds, sometimes
things break
or bend. To help proventthis, a front bumper
and side crash pods may be added to the chassis.
These
parts willhelp you in a crash situation. They willhelp keep
the front andrearaxles from being bent or broken.
The front axle beam that is supplied is made from
high-impact nylon. The magnesium front end will bolt onto
your chassis. This front end is slightly stronger. You will
needto buythe frontcross bar, cinch blocks, king pins, and
steering blocks. Contactyourlocaldealerformore informa·
tion. A graphite axle may
be added to replace the steel
diff axle. This will save some weight and give you better
differential action. Although the graphite axle is lighter, it
is
not as strong as the steelaxle. The graphite axle must be
used with rear ball bearings. Oi/ite bushings should not be
used.A complete diffkitis available.
The rear hubs that are supplied are made from
nylon. After a few crashes they may become bent. For
racing, aluminum hubs shouldbe used.
These will notget
bentaseasilyandthe rear
wh eels will run truer.
