Thank you for selecting the Team Losi Racing 8IGHT 2.0EU as your new racing buggy. The 8IGHT 2.0 platform has already distinguished itself as a
top caliber racing chassis. As you will see, we have made every eort to produce a vehicle that is not only the most competitive but also easy to main-
tain. The simple bag-by-bag assembly sequence and easily followed instructions with drawings combined with Team Losi Racing's world famous quality
tting parts will make using the 8IGHT 2.0EU a most enjoyable vehicle.
Before you open the rst bag, please take a moment to read through the following instructions. This will familiarize you with the various parts,
assembly tips and descriptions as well as the tools needed. This will also help you understand the dynamics of the 8IGHT 2.0EU and setup tips to ensure
the best possible experience.
Good luck and good racing,
Team Losi Racing
Welcome Team Losi Racing 8IGHT 2.0EU Owner!
Vehicle/Manual Organization:
The vehicle is composed of dierent steps marked A through H. Each bag
contains all of the parts necessary to complete a particular section of the
vehicle. Some of these bags have sub-assembly steps within them. You
should read through the instructions for an entire bag prior to working
on your vehicle. Next to each of the step numbers is a check box. At the
completion of each step, place a check in this box so that if you must
stop and come back to the assembly, you can begin where you left o.
For your convenience, an actual-size Hardware Identication Guide is
included as a fold-out page at the back of this manual. Hardware that is
not easily dierentiable in each step is called out with an icon which
contains a small picture of the part genre (referenced on the Hardware
Identication Guide), the quantity of that part required for what is shown
in the step, and the size or name of that part. To check a part, hold it
against the silhouette until the correct part is identied. Associated
with each of these parts, in the
Hardware Identication Guide, is
an LOSA Number which is used
when ordering replacement
parts for your 8IGHT 2.0EU. In
some cases, extra hardware has
been supplied for parts that may
be easy to lose.
You can identify components used in each step by their LOSA Number
and component name. With the exception of a few parts, these are not
referenced in the Hardware Identication Guide.
The molded parts in Team Losi Racing vehicles are manufactured to
demanding tolerances. When screws are tightened to the point of
being snug, the parts are held rmly in place. For this reason, it is very
important that screws not be over-tightened in any of the plastic parts.
In some steps there will be a lled black circle with a white number.
These indicate the specic order by which assembly must occur. In cases
where steps are repeated (front/rear or left/right) these numbers may
be omitted. Please note these numbers do not call out every sub-step
required for the step’s assembly procedures, they only highlight the
critical order required for assembly.
In each step,“Detail Icons”( ) call out critical precautions or assembly
tips for the process. There is a reference key that describes the meaning
of each of the icons located on the fold-out Hardware Identication
Guide at the back of this manual. To ensure that parts are not lost during
construction, you should work over a towel or mat to prevent parts from
rolling away.
IMPORTANT SAFETY NOTES:
1. Select an area for assembly that is away from the reach of small
children. Some parts in this vehicle are small and can be swallowed
by children, causing choking and possible internal injury; PLEASE USE
CAUTION!
2. The shock uid and greases supplied should be kept out of
children’s reach. They are not intended for human consumption!
3. Exercise care when using any hand tools, sharp instruments, or
power tools during construction.
4. Carefully read all manufacturer’s warnings and cautions for any
chemicals, glues, or paints that may be used for assembly and
operating purposes.
Age Recommendation: 14 years or over. This is not a toy. This product
is not intended for use by children without direct adult supervision.
Note: Final vehicle weight will vary depending on accessories used.
*All measurements taken at ride height 32mm.

CHECKLIST SETUP GUIDE
1. Breaking in the differential:
While holding the chassis with only the left side tires rmly on the ground, give the car about one eighth throttle, for 30 seconds. The right
side tires should spin freely during this time. Repeat this with only the right side tires held rmly to the ground, allowing the left tires to
spin. Repeat these steps at least two more times.
2. Check for free suspension movement:
All suspension arms and steering components should move freely. Any binds will cause the car to handle poorly.
3. Set the ride height:
Set the ride height on your buggy so that the bottom of the chassis is 24mm from the ground in front and 28mm in the rear by adjusting
the shock adjustment nuts, eectively increasing or decreasing pre-load on the springs. See the Setup Guide for additional information on
ride height adjustment.
4. Set the camber:
Adjusting the camber tie rod length changes the amount of camber. Use the Losi wrench to adjust the tie rods once installed. Rotating the
tie rods towards the front end of the vehicle will shorten the length, increasing negative camber. Rotating the tie rods towards the back
of the car will lengthen them, decreasing negative camber. Set the front tires to have 3 degrees of negative camber and ensure they are
adjusted equally, left to right. Set the rear tires to have 2 degrees of negative camber and ensure they are adjusted equally, left to right.
5. Set the front toe-in:
Adjust the front steering tie rods so that when the servo is centered on the transmitter, the front tires are both pointing slightly out with
2.5 degrees of toe-out. Refer to the Setup Guide for more information on toe-in/out.
6. Charge a receiver battery pack:
Charge a battery pack as per the battery manufacturer’s and/or charger manufacturer’s instructions so that radio adjustments can
be made.
7. Set the transmitter steering trim:
The steering trim tab on the transmitter should be adjusted so the car rolls straight when you are not touching the steering wheel/stick. If
the servo and steering link were installed correctly, the wheels should turn equally to the left and right. If this is not the case, refer to Table
2 and ensure the steering servo and horn were properly installed. Also check the steering link length as noted in Step A-01. Make sure the
throttle trim is set so the brakes are not“dragging”in the neutral position.
8. Set the transmitter throttle and brake trim:
The throttle trim tab on the transmitter should be adjusted so the brakes are not dragging in the neutral position. The idle adjustment
screw on the carburetor should be set at approximately 1mm open. When the throttle trigger is pulled back to the maximum, the
carburetor is fully opened.
BEFORE RUNNING YOUR NEW 8IGHT 2.0EU BUGGY run down the following checklist in order and complete the listed tasks. Please note that ne-
tuning of the initial setup is an essential part of building a high-performance buggy, so follow this simple Checklist and the Team Tips to make the rst
run with your new buggy much more enjoyable.
Before you start making changes on your 8IGHT 2.0EU O-Road Racing buggy, you need to make a few decisions. You will nd the best adjustment
will become a personal decision based on the “feel” each of these adjustments yield. Never make more than one change at a time. If the change you
made works adversely, or doesn’t address your need, return to the previous position and try something else. For the latest in setup and accessory
parts information, visit the Losi web site at: www.losi.com regularly. Also note that there are many ways to set up a car. The rules we follow can reverse
sometimes with dierent driving styles or dierent setup styles.
Droop:
Always measure the droop of the 8IGHT 2.0EU with the shocks on the buggy. Droop is always measured from the center of the top shock mount to
the center of the bottom shock screw and is usually accomplished with digital calipers for a precise measurement. More droop (travel) in the front has
more on-power steering and allows the buggy to roll more on the rear when on throttle. More droop (travel) in the rear increases o-power steering
and allows the buggy to roll on the front when o throttle. More front and rear droop accelerates better in bumps when going straight, but can cause
the buggy to traction roll in rough turns. Less front and rear droop slides over bumps better in turns and may be better on high-speed and high-
traction tracks. A general setup for shock length is 95mm in the front and 107mm in the rear.
Front Camber Links:
The lower camber link locations on the tower have more camber gain (total camber change through the suspension travel). Running the camber tie
rod in the lower holes increases o-power steering and makes the vehicle more aggressive; however you may lose some consistency. More camber
gain is good on small tight tracks. We nd that running less camber gain in the front suits the car the best for consistency and steering balance. On
the 8IGHT 2.0EU we oer a longer camber link on the spindle carrier. A longer front camber link makes the vehicle feel stier and this keeps the buggy
atter with less roll and increases high-speed steering. A short front camber link rolls more and makes the vehicle more aggressive. Too short of a
front link may make the vehicle feel twitchy.
Rear Camber Links:
The 8IGHT 2.0EU has only two vertical rows of camber locations on the rear tower. The stock camber link setup for the 8IGHT 2.0EU is location #2 on
the tower and B in the hub. A longer rear camber link provides less roll and improves stability and traction. A shorter rear camber link has more roll
and increases steering and better handling in the bumps. By raising the inner camber link up you increase the roll stiness of the vehicle. This can
make the vehicle easier to drive but may reduce corner speed and hurt bump absorption. Running “A” in the rear hub generates more corner rotation
entering the turn, but decreases steering on exit. Running“B” in the hub is more stable entering the turn and increases steering on exit.
Kingpin Inclination:
The 8IGHT 2.0EU is equipped with king pin inclination. We nd that on high-speed tracks the king pin inclination provides an increase of precision
steering while keeping the front of the car atter. This has shown to improve handling in rough portions of the track. The 8IGHT 2.0EU is equipped
with 12-degree Spindle Carriers, however 10-degree Spindle Carriers (LOSA1728) are oered as an option part. Less caster ultimately has less o-
power steering but improves on-power steering.
Camber:
More negative camber in the front has more steering and is more responsive. Less negative camber in the front has less steering and is smoother.
More negative camber in the rear has less rear traction, but increases on-power steering and is less grabby in bumps. Less negative camber in the rear
has more rear traction and makes the rear of the buggy stay atter, but if traction is lost it is more violent. To ensure your 8IGHT 2.0EU has the correct
camber we recommend using our Losi Camber Gauge (LOSA99172).
