As you tighten the diff bolt, you will notice the T-nut ears moving
closer to the bottom of the outdrive slot. This compresses the
spring behind the T-nut. The spring should be completely
compressed at the same time the T-nut reaches the end of the
slot. Caution! Pay close attention to the feeling when the spring
is completely compressed. Do not overtighten the bolt. When
you feel the spring completely compressed, loosen the diff bolt
1/8” of a turn. Your diff should now operate smoothly with
resistance as the outdrives move in opposite directions.
After you have driven the car once, re-check the diff setting.

Shock Bleeding Steps:
1. Before assembly, get each bleed
screw and thread it 1-2 turns into
the shock cap. This will make it easier
when you are bleeding your shocks.
2. Pull shock shaft down.
3. Fill shock body 3/4 full with silicone
shock fluid.
4. Slowly move the shock shaft up and
down to remove air from under the
piston.
5. Wait for bubbles to come to surface.
6. Fill shock body to top with silicone
shock fluid.
7. Place a drop of oil in the cap and on
cap threads.
8. Install cap (without bleed screw) and
tighten completely.
9. Slowly compress shaft all the way to
bleed excess silicone shock fluid out
the hole in the cap (use rag around-
shock to catch excess fluid).
10. Install M2x4mm button head screw
until snug while shaft is fully com-
pressed.

ate body. You will need to prep the body before you
can paint it. Wash the inside thoroughly with warm
water and liquid detergent. Dry the body using a
clean, soft, lint-free cloth. Use the supplied window
masks to cover the windows from the INSIDE of the
body (RC cars get painted from the inside). Using
high quality masking tape, apply tape to the inside of
the body to create a design. Spray (use either rattle
can or airbrush) the paint on the inside of the body
(prefferably dark colors first, lighter colors last).
NOTE: ONLY use paint that is recommended for use
with (polycarbonate) plastics. If you do not, you can
destroy the plastic body!!!!.
After paint has completely dried, cut the body along
the trim lines. Make sure to drill or use a body reamer
to make the holes for the body mounts and antenna!

Racers Tip:
Instead of using the included body clips
(#21173), you can use hook and loop tape
on the inside of the body, and the sides of
the chassis to keep your body in place!

:: Tuning Tips
Tips for Beginners:
Before making any changes to the standard setup, make sure you can get around the track without crashing.
Changes to your vehicle will not be beneficial if you can’t stay on the track. Your goal is consistent laps.
Once you can get around the track consistently, start tuning your vehicle. Make only ONE adjustment at a time, testing
it before making another change. If the result of your adjustment is a faster lap, mark the change on the included setup
sheet (make adddtional copies of the sheet before writing on it). If your adjustment results in a slower lap, revert back
to the previous setup and try another change.
When you are satisfied with your vehicle, fill in the setup sheet thoroughly and file it away. Use this as a guide for future
track days or conditions. Peridicaly check all moving suspension parts. Suspension components must be kept clean
and move freely without binding to prevent poor and/or inconsistent handling.
Slipper Clutch:
The assembly instructions give you a base setting for your clutch. Turn the nut on the shaft so that the end of the top
shaft is even with the outside of the nut. At the track, tighten or loosen the nut in 1/8 turn increments until you hear
a faint slipping sound for 1-2 feet on takeoffs. Another popular way to set the clutch is to hold both rear tires firmly in
place and apply short bursts of throttle. If the clutch is properly set, the front tires should lift slightly up off the surface.
Motor Gearing:
Proper motor gearing will result in maximum performance and run time while reducing the chance of overheating and
premature motor failure. The gear ratio chart lists recommended starting gear ratios for the most widely used
motor types. Gear ratios will vary depending upon motor brand, wind, and electronic speed control. Consult your
motor and electronic speed control manufacturers for more information.
Team Associated is not responsible for motor damage due to improper gearing.
Set The Gear Mesh:
You should be able to rock the spur gear back and forth in the teeth of the pinion gear without making the pinion gear
move. If the spur gear mesh is tight, then loosen the #31532 screws and move the motor away, then try again.
A gear mesh that is too tight or too loose will reduce power and damage the gear teeth.
* These gearings are for use with advanced timing speed control settings!

Ride Height:
Ride height is the distance from the ground to the bottom of the chassis.
The standard front ride height setting is with the front arms level
(reffered to as “arms level”) or 24mm (Ride Height Gauge #1449).
Check the ride height by lifting up the entire car about 8-12 inches off the
bench and drop it. After the suspension “settles” into place, measure
ride height (Ride Height Gauge #1449). Raise or lower the shock collars
as necessary so that the left & right arms appear to be level.
The rear ride height setting you should use most often is with the
outdrive, driveshaft, and axles all on the same imaginary horizontal line
(reffered to as “bones level”) or 24mm (Ride Height Gauge#1449).

:: Tuning Tips (cont.)
Caster:
Caster describes the angle of the kingpin as it leans toward the rear of the vehicle. Positive caster means the kingpin
leans rearward at the top. The B5 includes two inserts to adjust caster angle at the caster block, 0°and +5°. The total
caster angle is the sum of the kick-up angle and the caster block angle. Standard total caster angle for the B5 is 30°,
with 25°kick-up and 5°caster block angle. For less entry steering and more exit steering, try 0°caster block angle.
Rear Camber:
Camber describes the angle at which the tire and wheel rides when looked at from the back. Negative camber means
that the tire leans inward at the top. A good starting camber setting is -1°. Adding a small amount of positive camber,
where the top of the tire is leaning out, will tend to improve straight-line acceleration on loose tracks.
Optional #1719 camber gauge can be used to more accurately set camber.
Front Camber Links:
Changing the length of the camber link is considered a bigger step than
adjusting the ball end height on the tower. Shortening the camber link
(or lowering the ball end) will give the front end less roll and quicken steering
response. Lengthening the camber link (or raising the ball end) will give the
front more roll and slower steering response. Longer camber links are
typically used on high grip tracks and shorter links tend to work better on
medium-grip loose tracks.
*Raise or lower the
ball end by adding
or subtracting
washers here
!
Rear Camber Link:
Changing the length of the camber link is considered a bigger step than adjusting
the ball end height on the rear chassis brace. Shortening the camber link
(or lowering the ball end) will give the rear end less roll and the car will tend to
accelerate or “square up” better. Lengthening the camber link (or raising the ball
end) will give the rear more roll and more cornering grip. Longer camber links are
typically used on high grip tracks, while shorter links tend to work better on
medium grip loose tracks. The kit setting is the best compromise of cornering grip
and acceleration.

the ball end by
adding or

Wheelbase Adjustment:
You have three options for rear hub spacing, Forward, Middle, & Back.
The kit setting of Middle is the most neutral, and will be used most often.
For improved handling in bumps or rhythm sections, try moving the hubs to the
Back position. This can also make the car handle better in 180° turns.
*Spacers to the rear
will place hubs for-
ward, shortening
the wheelbase
!
Front Camber:
Camber describes the angle at which the tire and wheel rides when
looked at from the front. Negative camber means that the tire leans
inward at the top. A good starting camber setting is -1°. Positive camber,
where the top of the tire is leaning out, is not recommended.
Optional #1719 camber gauge can be used to more accurately set camber.

Kickup:
Kickup is the angle the front suspension arm mounts at where the front of the arm is higher than the rear.
The standard kickup angle for the B5 is 25°, and is most common. If more corner entry steering is desired, try the
included 30° front bulkhead. It is important to adjust the bumpsteer to match the kickup angle adjustment.
Refer to the chart below for some common settings:

:: Tuning Tips
Ackermann:
Ackermann is the angle difference between the front wheels when they are turned to steer the car. For minimal tire
slip, it is standard for the inside wheel to steer to a greater angle than the outside wheel. The B5 allows ackermann
adjustments by changing the washer thickness used behind the steering rack ballstuds. The kit setup uses 2mm wash-
ers and is most common for racing conditions. If corner entry steering is too aggressive, try increasing the ackermann
by removing shims from behind the steering rack ballstuds. Increasing the ackermann will increase the angle difference
of the front wheels when steered, resulting in a more stable car on corner entry.
Anti-Roll Bars:
The optional #91468 rear anti-roll bar kit (also called the “swaybar”) allows you to add roll resistance to the rear end
with minimal effect on handling over bumps and jumps. It is an especially helpful tuning item on high-grip tracks
(try the gold bar). The silver and black anti-roll bars are typically used on medium-grip loose tracks.
Trailing Axle:
Trailing axle is the distance from the king pin to the axle that “trails” behind the pin. The B5 includes inserts to allow
adjustments for trailing axle to three positions: 4mm (standard), 3mm, and 2mm. The standard setup uses 4mm
trailing axle for the most stable handling. For more corner entry steering, try the 3mm trailing axle option.
It is important to adjust the ackermann and wheelbase settings to match the trailing axle adjustment. refer to the
chart below for some common settings:
