STEERING RACK ASSEMBLY
Attach two #3858 short ball ends to the #3855
steering rack and one #3858 short ball end to the
#3855 steering rack arm.
Slide the #6587 spring and the #3855 rack shim onto
the #6918 screw. Slide the screw assembly through
the bottom of the steering rack.
Attach the #3855 rack arm to the rack with a #4449
locknut.
Tighten down the spring until the screw is flush with
the top of the nut.
Make sure the rack arm is facing
the rear when assembled on the
rack: The ball end on the rack arm
and the ball ends on the rack should
be pointing in opposite directions.

Step 1
1:1
BEFORE BUILDING
OPEN THE BAGS IN ORDER
The assembly is arranged so that you will open and finish
that bag before you go on to the next bag. Sometimes you
will have parts remaining at the end of a bag. These will
become part of the next bag. Some bags may have a large
amount of small parts. To make it easier to find the parts, we
recommend using a partitioned paper plate for spreading out
the parts so they will be easier to find.
MANUAL FORMAT
The following explains the format of these instructions.
The beginning of each section indicates:
1Which bag to open ("BAG A") and which steps you'll be
using those parts for ("FOR STEPS 1-3").
2Which parts you will use for those steps. Remove only the
parts shown. "1:1" indicates an actual size drawing; place
your part on top and compare it so it does not get confused
with a similar part.
3Which tools you should have handy for that section.
4In some drawings, the word "REAR" with an arrow
indicates which direction is the rear of the car to help keep
you oriented.
5 The instructions in each step are ordered in the order you
complete them, so read the words AND follow the pictures.
The numbers in circles are also in the drawing to help you
locate them faster.
6When we refer to left and right sides of the car, we are
referring to the driver's point of view inside the car.
7Occasionally you will see an upside-down triangle next to a
part. This indicates that more information is given about
the part next to the matching triangle near the text.
SUPPLEMENTAL SHEETS
We are constantly developing new parts to improve our kits.
These changes, if any, will be noted in supplementary sheets
located in a parts bag or inside the kit box. Check the kit box
before you start and each bag as it is opened. When a
supplement is found, attach it to the appropriate section of the
manual.

ADJUST THE DIFF
As you tighten the diff bolt, you will notice the T-nut ears moving closer to the bottom of the diff hub slot. This compresses the spring
behind the T-nut. The spring should be fully compressed at the same time the T-nut reaches the end of the slot. Caution: Pay close
attention to feeling when the spring is full compressed. Do not overtighten the bolt.
When you feel the spring fully compressed, loosen the diff bolt 1/8 to 1/4 of a turn. No more, no less. Your diff should now operate very
smoothly when turning the hubs in opposite directions. After you have driven the car once, recheck the diff adjustment. Never adjust
the diff any other way.
Now assemble the second diff the same way.

not down. Remove four #2
shock pistons.
Remove remaining burrs
carefully with a hobby knife.

Holding the shock
upright, fill with oil
to the top of the body.
Slowly move the
shaft up and down
several times to
allow air bubbles
to escape to the top.
Refill with oil to the
top of the body.
Push the shaft up until
the piston is level with
the top of the body.
The oil will bulge up
above the shock body.
Fill The #6428 shock cap about
halfway with oil and install onto
the body. Try to retain as much
oil as possible during assembly.
The shaft will extend out as you
tighten the cap down.
step 4
SETTING THE
REBOUND
Move the shock shaft
in and out a few times
an then push it all the
way in. It should be
easy to push the shaft
in until the eyelet hits
the body
Then the
shaft should
push itself
out to its full
length very
slowly.
If the shock
does not push
out this far
there is not
enough oil in it.
Add just a little
oil and try
steps 6-7
again.
If the shock rebounds too
fast, or you cannot push the
shaft in until the eyelet hits
the body, there is too much
oil. Loosen the cap about a
full turn and pump out a small
amount of oil by pushing the
shaft in. Retighten the cap
and try steps 6-7 again.

Use the following steps to make the final adjustments
on your car.
1. Turn the transmitter on.
2. Make sure the motor is disconnected.
3. Connect your battery pack.
4. Turn the power switch on.
5. Move the steering control on the transmitter to the
right and left. Do the wheels move in the correct di-
rection? If not, you must reverse the steering servo
direction on your transmitter (see radio manual.)
6. Look at the servo horn mounted on the servo. It
should lean toward the centerline of the chassis about
1/8” (3mm).
7. Adjust the servo turnbuckle so that the steering
rack arm is EXACTLY in the center of the car.
8. Using the two steering turnbuckles, adjust the front
wheels so they are pointed straight ahead.
9. Adjust the ESC (electronic speed control) accord-
ing to the speed control manufacturer’s instructions.
Note: Some manufacturers have the motor connected
during adjustment and some do not. Now turn the
power switch off.
10. Connect the motor. Place your car on a block or
car stand so that all four wheels cannot touch any-
thing.Turn the power switch on again. Check the ESC
and steering settings you have made and then turn
the power switch back off.
10. Remember this! The transmitter is always the
FIRST TO BE TURNED ON and THE LAST TURNED
OFF.

MOTOR GEARING
To get the most from your motor, proper gearing is
important. The gear ratios listed in the chart are rec-
ommended starting gear ratios. Ratios can vary from
track to track, but you should not change the pinion
size more than one tooth from the recommended ra-
tio.
CAUTION! Increasing the pinion size by more
than one tooth can damage your motor from excess
heat.

MAINTENANCE
Follow these steps to keep your car in shape for racing
CHECK FOR FIT
You should periodically check all the moving parts:
front and rear end, suspension arms, steering blocks,
steering linkage, shocks, and so on. If any of these
should get dirty or bind then your car’s performance
will suffer.
MOTOR MAINTENANCE
Between runs, inspect the brushes to ensure they
are moving freely in the brush holder.This is done by
carefully removing the spring and sliding the brush in
and out of the holder. If there is any resistance or
rough spots, remove the brush and carefully wipe the
brush clean. This will clean off any buildup and lubri-
cate the brush so it slides smoothly in the brush
holder.
After every 3 to 5 runs, remove the brushes from
the holders and inspect the tips for wear and/or burn-
ing. If there is a noticeable amount of wear, replace
the brush with a new pair. If the tip is a burnt blue
color, then the lubricant in the brush has been burned
away and new brushes should be installed.
After every other battery charge you should care-
fully clean the motor. One recommended method is
to spray motor cleaner directly on the brush and com-
mutator area. Run the motor for approximately 15
seconds. Disconnect the motor and spray it again,
making sure the runoff is clear and clean. If the run-
off is still dirty, repeat the spraying action until clean.
After completing the cleaning, apply a small amount
of lightweight oil to each bushing or bearing for lubri-
cation. Be careful not to apply too much oil, for this
will pick up dirt and contaminate the commutator and
brushes. 19
FINISHING THE BODY
Before you start to mask and paint the inside of your
TC3’s body, wash it out with soap and water to re-
move any mold release residue or dirt that may show
up in your paint.
1. Mark the body post holes and rear wheel cutout
with a marker on the outside of the body.
2. Each body comes with pre-cut self-adhesive win-
dow masks for your convenience.
3. Be sure to use a paint that is specifically formu-
lated to adhere to Lexan. Spray several thin coats
(instead of one thick coat) to avoid runs. If possible,
spray your darker colors first.
4. After painting, trim the wheel wells with curved
scissors or a sharp hobby knife.
5. Trim out the rear wing and mount it to the body with
the supplied 4-40 button head screws and nylon nuts.
6. Finish by applying decals.

TUNING & SETUP TIPS
These tips prepare your car for maximum performance
DIFFERENTIAL ADJUSTMENT
1. Tighten the diff screw down until the T-nut reaches
the bottom of the diff hub slot and you feel the spring
fully compressed. Do not overtighten. When you feel
the spring fully compressed, loosen the diff bolt 1/8
to 1/4 of a turn. No more, no less.
2. Go ahead and run the car for approximately one
minute. Then recheck the diff adjustment by again
following step 1 above.Your diffs should be ready to
go now.
20
DIFFERENTIAL MAINTENANCE
You should rebuild the differentials when the action
gets somewhat “gritty”feeling. Usually cleaning the
diff parts and applying new lube per the instructions
will bring it back to new condition again. The stan-
dard 3/32”carbide balls rarely need replacing. Nor-
mally, as the parts seat, the diff will get smoother.
If the diff still feels gritty after carefully cleaning
and re-lubing the diff parts, the thrust balls, thrust
washers, and drive rings should be checked and pos-
sibly replaced.
The parts will normally wear out in the following
order:
1. #6575 5/64”diff thrust balls (qty 6).
2. #6573 diff thrust washers (2).
3. #6579 diff drive rings (2).
Refer to the differential section to correctly as-
semble the diff.
Your car is one of the most tunable on road cars on
the market. This section will try to explain the parts
and adjustments you can use to tune your car for
different track conditions.
CASTER describes the angle of the kingpin from
vertical when looked at from the side of the car. Posi-
tive caster means the kingpin leans rearward at the
top. Negative caster should never be used.
Associated makes block carriers for the TC3 with
0°(kit standard), 2°, and 4°of caster. Increasing caster
in the TC3 (with 2°or 4°block carriers) will give your
car more steering entering corners but less steering
exiting corners. It will also be more stable in bumpy
conditions.
Note: When figuring total caster in your car, add
the amount in the block carrier to the amount of kickup.
Example: 2°of kickup (kit standard) and 0°block
carrier equals total of 2°of caster.
Positive caster means the
kingpin leans rearward at
the top.
0°block carrier, #3868
2°block carrier, #3870
4°block carrier, #3872
FRONT
FRONT TOE-IN AND TOE-OUT is
adjusted by turning the steering turnbuckles. Toe-in
will make your car easier to drive by improving stabil-
ity during acceleration. Toe-out will increase steering
when entering corners but will be slightly more diffi-
cult to drive.We suggest using 0°to 1°toe-out on the
TC3.
Toe-in:
Easier to drive.
Improves stability during acceleration.
Toe-out:
Harder to drive.
Increases steering entering corners.
KICKUP AND ANTI-DIVE refers to the angle at which the front
suspension is mounted in relation to horizontal when looked from the side
of the car. Kickup and anti-dive are adjusted by changing the suspension
arm mounts, which have molded codes to help you tell them apart. The
three front arm mount combinations are as follows: The kit setting of 2° kickup
will work best in most con-
ditions, especially in bumpy
conditions.
0° kickup will have a more
aggressive steering feeling
but will not absorb bumps
as well as 2°.
2° anti-dive will have a very
aggressive steering feeling
and will improve front brak-
ing traction entering cor-
ners. However, this setting
will not work well in bumpy
conditions.

REAR ANTI-SQUAT describes the angle
at which the rear suspension is mounted in relation
to horizontal when looked at from the side of the car.
The TC3 comes standard with 2°of rear anti-squat.
This provides good rear traction. Installing the #3864
(R3+0) rear arm mount reduces anti-squat to 0°and
will reduce rear traction. However, it will improve ac-
celeration in bumpy conditions and increase steering
slightly.

FRONT
REARTOE-INis adjusted by changing the rear
arm mounts.The TC3 comes standard with 3°of toe-
in on each side. This setting should work best in any
condition. However, if less toe-in is desired, install
the #3864 (R+2+2) or #3864 (R+2+0) rear arm
mounts. These mounts have 2°of toe-in and will de-
crease rear traction and add steering. (See rear anti-
squat details above for more info on the mounts.)
CAMBER describes the angle the wheels ride
relative to the ground when looked at from the front
or back. Negative camber means that the tire leans
inward at the top. Positive camber means just the
opposite, and should not be used. We suggest using
2°of negative camber at all times. However, more
negative camber can be used up to 4°for high trac-
tion conditions. Less than 2°can be used for low trac-
tion conditions.
Negative camber means
that the tire leans inward at
the top. Change camber by
turning the camber link.
CAMBER LINK LOCATIONS on the
TC3 have been thoroughly tested to find the best all
around positions. We suggest using the standard
setting for all conditions. However, if you must make
adjustments, the following guidelines should help you:
The longer or higher the link, the more traction and
less stability. The shorter or lower the link, the less
traction and greater stability.
Camber link possibilities for the rear tower and
hub carrier. Standard setup shown.
Camber link possibilities for the front tower. Standard
setup shown.
WHEELBASE ADJUSTMENT can be
made to theTC3 by moving the two #4187 1/32”plas-
tic spacers on the outer rear hinge pins (next to the
hub carrier).
Moving the spacers to the front of the hub car-
rier will lengthen the wheelbase and decrease rear
traction.
Moving the spacers to the rear of the hub car-
rier will shorten the wheelbase and increase rear trac-
tion.
RIDE HEIGHT describes the height of the
chassis in relation to the surface it is sitting on. This
adjustment must be made with the chassis ready-to-
run but with no body.The #8846 shock preload spac-
ers are used for raising and lowering the ride height.
We suggest starting with about 1/4”(6.3mm)
clearance between the chassis and ground. Try us-
ing a slightly lower right height for high traction con-
ditions such as carpet racing. Do not use a ride height
lower than 5/32”(4mm).
ACKERMAN is a term describing the effect of
the inside front wheel turning tighter than the outside
front wheel. The standard setup works best in most
conditions and will provide a very neutral driving feel-
ing.
By adding two .100”(2.5mm) spacers and the
longer #3858 ball ends to the steering rack, a more
aggressive steering feeling can be achieved. This is
because there will be less ackerman.
Ideal ride height is be-
tween 1/4”(6.3mm)
and 5/32”(4mm).
Optional ackerman.
For a more aggressive steering feeling.
Standard ackerman.
For a neutral steering feeling.
