Team Magic B8RS Instruction & Setup Manual

Thank you for choosing the Team Magic B8RS. Before you start building the B8RS, we suggest you read
though the instruction manual first. Be sure to check all assembly and performance tips before you
start. We hope you enjoy the fine building processes.

General Building Tips:

Read the instruction manual before building.

Clear a work area and try to work on a light color towel to avoid missing dropped parts.

Don't forge the thread lock. Be certain to use thread-lock on all the machine screws that thread into metal. Put it

on the screws that are secured with locknuts and the setscrews that secure the linkage stops, too. Don't skimp on

the thread-lock or you'll be searching in the dirt for screws that vibrated loose.

Don't over-tighten fasteners. Many assembly problems are caused by over-tightening screws or nuts. Don't use too

large a grip. Please go slowly and feel the resistance build. Just snug it up.

As you put more time and runs on the car, the suspension arms, and basically anything else that moves, can stretch

and wear. Though we have a very rigorous quality control program and make every effort to ensure that the parts

have the best possible fit when you get them. Unfortunately there is very little, or nothing we can do to prevent

these parts from wearing out. When the arms begin to wear you will notice that some slop develops between the

carrier or hub and the arms. This slop can be taken out by shimming the arm, hub or carrier. If you take a look at

any of the factory driver's cars you will definitely find that they use shims to take up some of the slop that occurs over

a period of time. The shims can also be used on the inside of the suspension arms in the same manner. When

shimming the parts, care must be taken not to add too many shims. The parts must still move freely without binding.

When it doesn't fit, please double check. If an assembly is not going together correctly, then either there really is a

bad fit (e.g. a part is damaged or defective) or a mistake in assembly. Always re-read the instructions when there

are any problems. If you cannot figure out what's wrong, always ask dealer, distributor or Team Magic. Don't use

force beyond what the instructions call for.

Using the right tools makes assembly much easier. The instructions below finely indicate you what tools to get to

make things easier. We don't want to scare you by saying that all these tools are required, but you will have an

easier time if you have them. Borrow them from a friend to check if necessary.

The assembly is arranged so that you will open the bag 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 following bags.

A Good Dealer Is Extremely Important!!

A good hobby dealer can help you with most assembly problems you might encounter. This is the main reason why
you should buy your kits from a good dealer rather than from the cheapest dealer. Bring your problematic parts to
the dealer and, most likely, you'll walk away soon thereafter with the problem solved. If you think that you really
don't have the mechanical skills to complete the assembly, you may pay your dealer to finish the job for you. We
can recommend good dealers to you if you need. Please send us mails for more information. Email:

Before start to setup the car, please always keep the following principles in mind.

We are not born to know all the setup knowledge. Always read, ask and learn more from dealers,
web sites, expert drivers and magazines. After you have some basic knowledge, you can judge the
problems. Driving skills, assembly quality and tuning ability all can affect the car performance. It's
important to evaluate what's the problem first.

If you follow all the steps on the instruction manual, you should get a B8RS with the basic setup. This
is the also the basic setup we suggest you to start from. With the basic setup, the B8RS should work
properly on most off-road tracks and proper terrains. If you need more from the B8RS, please learn
all the information and setup procedures below.

Every part functions properly

Always make sure that suspension and transmission systems are free without additional play and
binding. It's quite often that a poor handling car is caused by mechanical problems, instead of
poor setting. In addition, please always check when every part is still of good shape. Normally,
some parts get damaged or bent after crashes. These broken or bent parts can generate the most
unpredictable car. No setup can compromise these problems. If you cannot judge the problems,
please always ask help from dealers or experts.

Feel and use time counter

Feeling is helpful, but may cheat you. Sometimes, you feel the car is getting faster, but actually it's
slower. Always use time counter to check your lap time if you are at a track.

Make only one change every time

If you make many setup changes at a time, then you don't know which change make the
difference. This is extremely important. To help better judge the difference, a large change can be
helpful. For example, instead of add 0.5 degree to the toe setting, you may try 2 degree. Also,
don't forget to write down all these experiment results. You can always check the record to better
evaluate what changes should be made when you need better lap times.

Compromise

Things are not perfect. When you need more rear toe-in to have a stable car, you probably lose
some high-end speed. Always find the best compromise. What is the best compromise? Better
handling and faster lap times can help you to make decisions.

B8RS Setup & Tuning Guide

B8RS Specification

Basic Principles

Check the track layout and surface

It's good to walk and feel every part of the track. Then, you can know the bumpy area and find
good racing lines. It's normal that you cannot find these things on the driver stand.

It's always good to start from our basic setup or your own basic setup when you are at a new track.
Before start to drive the car, always do following things first:

Where To Start The Setting ?

B8RSB8RS

Check what other drivers are doing

Please try to find out the current best lap times. These are good benchmarkers. Check the setup
from other good drivers who drive the same car as you. You can save some try and error time.
Listen and see where good drivers apply throttle and brakes, also find out their racing lines.

Choose right tires

Tires are the only contact between the car and ground. Without a good set of tires, your car is
going no where. You can always check what tires are used the most at the track. This is always a
good starting point.

Shock Tuning

Ask

Local racers can always tell you what tire brands are the best at that particular track. Some tires
are good for qualification and some are good for the long final. Even the durability of wheel can
make difference. Some wheels brake easily and may cost you champion title. All these
information are quite open to all racers. Always check with your racing pal. Don't forget to check
the price as well!!

Tires are the most and first choice you should make. If you've got the right tires, you're 90% there.
Without suitable tires, the setup job will be very difficult. Always find out the best tires for the track
first. What we can do with the tires to get the best possible performance? There are mainly 2 ways
we can work on.

Shock Tuning is the 2 important thing when you setup the car. Measure your shocks after the
assembly. The right and left front shocks should be of the same length. In addition, bleed them so
that they all rebound to the same degree when they are compressed and released and so should
the right and left rear shocks.

Four adjustments can be used to tune your shocks: Preload, Springs, Damping and shock mounting
position. Below you will find all the related setup information.

Experience

Reading a track or the surface that you are running is not easy. So, choosing the right buggy tires
for the conditions can be very difficult. In addition to ask, experience is also the best teacher when
it comes to "reading" a track or surface. Things get real difficult when track conditions are
changing. If a track is drying up or has both hard sections and soft breaking up sections. Then the
only solution is doing back to back testing with different compounds. Then choosing the best tire
that suits your driving style. So, reading a racing surface can be difficult. But, it is part of the fun of
racing r/c cars and trucks.

nd

Springs

Compared with other shock-tuning adjustments, changing the springs offers the most noticeable
improvement in performance. Soft springs are the easiest to compress, and they provide more grip
because they allow the suspension to move with the bumps and the tires to stay on the ground.
However, keep in mind that damping and spring rate complement each other. Dramatic changes
in spring rate must be accompanied by changes in damping-mainly lighter damping with softer
springs and heavier damping with stiffer springs.

Setup & Tuning

Damping

Having the correct piston and shock oil combination is very important to shock tuning. A shock that
has thinner shock oil and a piston with more (or large) holes will compress and rebound faster than
a shock with thicker oil and less (smaller) piston holes. Keep in mind that the size or number of the
piston's holes dictates the range of shock oil that work best with it; small (less) holes work best with
thinner oil, and larger (more) holes work best with thicker oil. The suspension should never feel too
'springy' or too slow.

Basic Setup: Front #400wt Rear #300wt

Shock Mounting Position

Before experiment with different shock angles, make sure you get the best damping and spring
setup. Basically, shocks that are more horizontal than vertical feel softer when they are
compressed. Changing shock angle has a much less noticeable effect on performance than other
shock adjustments.

Differential Setup

4

Anti-Roll Bar

There are three differentials on the B8RS: one for the front, one for the center, and one for the rear
of the car. The effects that the diffs have in the handling of the car are noticeable; they can alter
the way a car handles bumps, exits a corner, and accelerates. As the B8RS differentials are
adjustable and pre-assembled in the factory with neutral setting, you can always make the diff
setting slightly tighter.

Front Differential

You can alter the amount of steering by altering the diff oil weights in the front diff. If you want
more steering entering the corner, try running lighter oil, such as 3000wt. More off-power steering
will be generated as well. Also, lighter oils are better for bumpy conditions. Heavier oils will give the
car better on-power steering. If the oil is too heavy, it will make the car oversteer in the rough or
rhythm sections.

Basic Setup: Front #5000 wt

Center Differential

Running lighter oils in the center helps the car track straight while accelerating (such as
3000~5000wt), but reduces acceleration out of corners. Heavier oils in the center (such as 7000wt)
will give the car better acceleration. However, for really bumpy sections have lighter oil in the
center will allow the car to accelerate better and straighter.

Adding an anti-roll car, or stiffening it, reduces traction at that end of the car. Therefore, it feels like
the opposite end has more grip. As anti-roll bars reduce body roll in turns, so they make the car
feel more direct, and make it change direction quicker. Normally, different thickness of anti-roll
bars are used to adjust the setup.

Basic Setup: Front #7000 wt

Basic Setup: Front 2.3mm Rear 2.7mm

Basic Setup: Rear #1000 wt

Rear Differential

Lighter oil in the rear diff gives the car more off-power steering, but may make the car feel
inconsistent around the track. If the car is not consistent, you can try to adjust the setscrews on the
rear diff to make the diff tighter.

Setup & Tuning

5

Wheelbase

The shorter the wheelbase the easier it is for the car to rotate in the corner. Also, when you adjust
the wheelbase by moving the rear axles forward, more weight will be put over the rear axle of the
car. It can cause an oversteer situation

Basic Setup: 2mm

Ackerman

More Ackermann means bigger difference in steering angle between the two front wheels and
vice verse. Add more shims generates more Ackermann effect. Less shims means less Ackermann
effect.

Front Camber

Camber describes the angle of the wheels as their tops lean to or away from the chassis. Negative
camber means the tire leans inward at the top. We don't use positive camber. Front camber is
largely affected by the caster angle. Higher caster angle (lean backward) requires less front
camber. Less caster angle needs more negative camber. Normally, we adjust upper arm
adjustable linkage rod to get the camber angle with the included 4.5mm flare nut wrench. H.A.R.D.
H7105 1/8 Buggy Cambertoe Setup Gauge is the right tool to setup the camber angle.

Basic Setup: Front -1

Front Toe

Toe-in/toe-out describes the angle of the wheels when viewed from above. Inward means toe-in
and outward means toe-out. The included 5mm flare nut wrench is used to adjust the steering
linkage rod to get the front toe angle you need. H.A.R.D. H7105 1/8 Buggy Cambertoe Setup
Gauge is the right tool to setup the camber angle.

Front Roll Center Setup

Roll center is determined by the car's suspension geometry. The roll center is a point around which
the chassis rolls. More chassis roll equals more grip. After adjusting the roll center, always make
sure the camber remains the same.

Toe-out Toe-in

More steering entering a corner
Instant steering response

Rear Camber

Camber describes the angle of the wheels as their tops lean to or away from the chassis. Negative
camber means the tire leans inward at the top. We don't use positive camber. Normally, we adjust
upper arm pivot ball to get the camber angle with the included 6mm flare nut wrench. H.A.R.D.
H7105 1/8 Buggy Cambertoe Setup Gauge is the right tool to setup the camber angle.

Basic Setup: Rear -3

Rear Toe

Toe-in/toe-out describes the angle of the wheels when viewed from above. Inward means toe-in
and outward means toe-out . We don’t use toe-out for the rear. Please use arm toe rod to adjust
the Toe-in/Toe-out and adjust the distance. ( 0.6 mm→1 degree , 1.2 mm→ 2 degree, 1.9 mm→ 3

Rear Anti-Squat

Rear anti-squat design is used to prevent the rear end from squatting down too much under
acceleration. It also helps the car to have a quicker initial acceleration. The harder you brake or
accelerate, the bigger the effect of anti-squat is.

More Anti-Squat Less Anti-Squat

A little more powering out of
corners
Jump a little higher and further
Resist squatting on corner exit
Better ability to handle large and
successive bumps
Too much anti-squat can make the
car spin out in turns

More rear traction while
accelerating on a slippery or
dusty track
More side bite
Little anti-squat makes the rear
end stable.

Basic Setup

14

Droop

Droop (or Down Stop) is used to limit the downward travel of the rear suspension. The droop (down
stop) point is measured as the distance between the ground and the bottom of suspension arm
(need to place the car on the wheels). Before start to measure the rear droop, please make sure
both left and right hub carriers are of the same level.

If the suspension is going to be able to absorb ruts and holes without upset the car, an adequate
droop setting is critical.

Basic Setup: Front - Max Rear - Max

Setup & Tuning

55

More Droop Less Droop

Better handling on bumpy tracks
Consistent traction
Land better after jumps

Change direction and cornering

Good for smooth surfaces

15

Ride Height

Ride height describes the distance of the car from the bottom of the chassis to the ground. To
setup the ride height, you will need to have the car fully equipped. Always check the ride height
after finishing all other adjustments. We suggest you to use ride height gauge to measure the
distance.

One a low-bite track you can increase the traction by raising the ride height. Normally, the higher
the ride height, the more grip you are going to have. Less ride height generally means less grip
because you have less weight transfer. When adjusting ride height, don't raise the height so much
that the car no longer has any droop (please find the next section).

Basic Setup: Front 27mm Rear 29mm

Setup & Tuning

16

Rear Wing

A bigger wing or at more of an angle can add rear downforce and generate more rear traction.
Side wing is more for cornering traction.
