8IGHT 2.0 COMPLETED KIT SPECIFICATIONS *All measurements taken at ride height (32mm).

Overall Chassis Length: 16.35" (415mm) Wheelbase: 12.71"-12.87" (323-327mm) *Front Track Width: 12.13" (308mm)
Overall Length w/Tires: 19.5" (497mm) *Overall Height: 6.625" (168mm) *Rear Track Width: 12.13" (308mm)
Note: Final vehicle weight will vary depending on accessories used. Table 1: 8IGHT 2.0 Completed Vehicle Specifications.
Vehicle/Manual Organization:
The vehicle is composed of different steps marked A through H. Each step contains all of the parts necessary to complete a particular section of the
vehicle. Some of these steps have sub-assembly steps within them. It is helpful to read through the instructions for an entire step 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 will be able to pick up where you left off.
For your convenience, an actual-size Hardware Identification Guide is included as a fold-out page at the back of this
manual. Hardware that is not easily differentiable in each step is called out with an icon which contains a small picture
of the part genre (referenced on the Hardware Identification 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 identified. Associated with each of these parts, in the Hardware Identification Guide, is an LOSA-Number which is used when ordering replacement
parts for your 8IGHT 2.0. In some cases, extra hardware has been supplied for parts that may be easy to lose.
Components used in each step are identified by their relative LOSA-Number and the component’s name. With the exception of a few parts, these are
not referenced in the Hardware Identification 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 firmly in place. For this reason, it is very important that screws not be overtightened in any of the plastic parts.
In some steps there will be a filled black circle with a white number. These indicate the specific order by which assembly must occur. In cases where
steps are repeated (front/rear or left/right) these numbers may be omitted. Please note that these numbers will not call out every sub-step required
for the step’s assembly procedures, they will only highlight the critical order required for assembly.
In each step, there are specific “Detail Icons” (shaped like a stop sign) that 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 Identification Guide at the back of this manual.
To ensure that parts are not lost during construction, it is recommended that you work over a towel or mat to prevent parts from rolling away.
TOOLS REQUIRED FOR ASSEMBLY
Team Losi Racing has supplied all necessary Allen wrenches and special wrenches that are needed for assembly and adjustments. The following
common tools will also be required: needle-nose pliers, regular pliers, hobby knife, scissors or other body cutting/trimming tools, and a soldering iron
may be necessary for radio installation. 3/16", 1/4", 5/16" and 11/32" nut drivers are optional.
RADIO/ELECTRONICS
A suggested radio layout is provided in this manual. Your high-performance RC center should be consulted regarding specific questions pertaining to
radio/electrical equipment.
HARDWARE IDENTIFICATION
When in question, use the Hardware Identification Guide at the back of this manual.
• For screws, the prefix number designates the thread size and number of threads per inch (e.g., 4-40 is a #4 size thread with 40 threads per inch).
The second number, or fraction, designates the length of the screw. For cap head and button head screws, this number refers to the length of the
threaded portion of the screw. For flat head and setscrews, this number refers to the overall length of the screw.
• Bearings and bushings are referenced by the inside diameter (I.D.) x outside diameter (O.D.).
• Shafts and pins are designated by type (Roll, Solid) and referenced by diameter x length.
• Washers, Spacers and Shims are described by inside diameter or the screw size that will pass through the inside diameter x the thickness or by their
designated application (e.g., Ball Stud washer is primarily used under a Ball Stud).
• Retaining Clips are sized by the shaft diameter that they attach to or by type (Body). The Hardware Icon associated with E/C-clips only designates
the part genre of clips, not the actual part.
• Nuts come in four types, Non-Flanged, Flanged (F), Plain and Locking (L) (designated on the Hardware Icons). The prefix number designates the
thread size and number of threads per inch. The second number, or fraction, designates the size of the hex. For example, L 4-40 x 1/4" designates a
locknut that will thread onto a 4-40 screw using a 1/4" nut driver.
• Setscrews come in three types, Cup (C), Flat (F) and Oval (O) (designated on the hardware Icons). The prefix number designates the thread size and
number of thread per inch. The second number, or fraction, designates the length of the threaded portion of the screw.

• Clean the 2-56 x 1/4" Button Head Screw and apply Losi-Lok to the threads.
• Install the #54 Shock Piston on the front shock shaft and a #56 Shock Piston on the rear shock shaft using the 2-56 x 1/4" Button Screw into the
Shock Shaft with a .050" Allen Wrench.
• Place a drop of Shock Oil into the bottom of the Shock Body to lubricate the Shock Seals.
• Thread the Shock Shaft into the Shock End using pliers. Used caution when threading the Shock Ends onto the Shafts. Avoid gouging or
scratching the Shock Shaft while gripping the Shock Shaft with pliers by placing the edge of a towel over the shaft, then gripping the portion of
the shaft covered by the towel. This method will work very well to protect the Shock Shafts from damage.
• Ensure the Shaft is fully extended when filling the shock.
• Fill the Front Shock Body with 40 wt Shock Oil and the Rear Shock Body with 25 wt until the oil is to the top of the body.
• “Work” the Shock Shaft up and down 8 times. This will release the air bubbles trapped beneath the piston. Place the filled shock, in the upright
position, off to the side for a few minutes until the air bubbles escape from the oil.
• Once all the air bubbles are out of the oil, gently place the Shock Bladder onto the shock as shown. Some oil should “bleed” from the shock.
• Screw the Shock Cap onto the Body until some resistance is felt.
• Slowly push the Shock Shaft up. This will bleed excess oil from the shock.
• Tighten the cap all the way down using the shock tools included in your vehicle.
• Move the Shock Shaft up and down. The shaft should be easy to push up into the body of the shock. If increased pressure is felt towards the top,
there is too much oil in the shock. Loosen the Shock Cap and “bleed” the shock as done previously.
• Make sure each pair (front/rear) Shocks have the same rebound and compression. This is checked by holding one shock in each hand horizontally
and pushing them together by the Shock End. Watch carefully to ensure that both compress evenly. Now release both shocks and again watch
carefully as they should rebound the same.
• Install the Shock Adjustment Nut O-ring into the Shock Adjustment Nut before installing the Nut onto the Shock Body.

to hold it onto the wheel. Losi offers a complete tire gluing kit which includes glue and tire gluing rubber bands (LOSA7884).
• Now slightly pull back the tire bead from the wheel and apply a thin bead of glue between the tire bead and the wheel all the way around, wait for this side to dry
and do the same to the other side until the tire is firmly adhered to the wheel. Allow the glue to dry thoroughly before continuing.

Painting:
Prepare the Lexan Body for painting by washing it thoroughly (inside and out) with warm water and liquid detergent. Dry the body with a clean,
soft cloth. Use the supplied window masks to cover the windows from the inside. A high-quality masking tape should be used on the inside of the
body to mask off any stripes, panels, or designs that you wish to paint on the body. Use acrylic lacquer or other paints recommended for Lexan
(polycarbonate). (NOTE: LEXAN RC CAR BODIES ARE MEANT TO BE PAINTED FROM THE INSIDE!) Apply paint to the inside of the Body. Remove the
masking tape for the next color and continue. Try to use darker colors first. If you use a dark color after a light color, apply a coat of white paint over
the lighter color before applying the darker color, or if you are painting over white, coat it with silver. This will help prevent the darker color from
bleeding through the lighter color.
Mounting:
The body is already cut out for mounting. However you will need to cut out the area for the pipe stinger. This should be done before you paint your
body so you can easily see where it exactly needs trimmed.
Stickers:
After the body is mounted, REMOVE THE PROTECTIVE FILM ON THE OUTER SURFACE, now you can apply the stickers.

 SETUP GUIDE
TIPS AND HINTS FROM THE TEAM
Before you start making changes on your 8IGHT 2.0 Off-Road Racing buggy, you need to make a few decisions. First of all, tires, and how they are set
up, have a tremendous impact on overall performance. Before you start making changes on the chassis setup, take a moment to observe a few of the
fastest cars at the track and what type of tire and inner liner they are running. You will find the best adjustment will become a personal decision based
on the “feel” that 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. Team Losi Racing development team has put hundreds of hours on the
8IGHT 2.0 to arrive at the setup we put in the instruction manual. If you find that you have lost the “handle” go back to the vehicle (stock) setup, as this
setup has proven to be reliable, consistent and easy to drive.
All of us at Losi are sure that you will find the 8IGHT 2.0 Off-Road Racing Buggy to be the most versatile and easiest car to drive fast, with great
consistency. We hope the information in the following guide helps you to enjoy your 8IGHT 2.0, and racing it, as much as we do. For the latest in setup
and accessory parts information, visit the Losi web site at: www.losi.com regularly. Please check the Losi web site periodically to find out new setup
information as we are always testing on all types of tracks and surfaces. Also note that there are many ways to set up a car. The rules we follow can
reverse sometimes with different driving styles or different setup styles, so test for yourself and you will find a set up that works right for you.
Tuning the Engine:
Should be done following the manufacturer's instructions. Turning the needle valve clockwise, the fuel mixture will become leaner – meaning that
the engine will draw less fuel. When the needle valve is turned counterclockwise, the fuel mixture becomes richer, meaning that, the engine will draw
more fuel. The high speed needle affects the fuel mixture at fuel throttle while the low speed needle only affects the fuel mixture at idle and the low
end of the throttle band.
To Shut Off the Engine:
Simply use the included pipe plug or simply bump the flywheel with a wrench or plastic handled tool. Losi also makes a tuning driver with a built-in
plug for the pipe (LOSA99167).
The Receiver Battery:
The receiver battery is an important, frequently overlooked part of gas-powered vehicles. A low receiver battery can cause the vehicle to have a
mind of its own. The result can be runaway vehicle or a poorly responding radio system. The length of time that a receiver battery pack’s charge lasts
depends on the type of servos that are used. If you will be using a NiCd or NiMH receiver pack, it is recommended that a minimum battery size of
1100mAh and minimum voltage of 5.4 volts be used. Recommended batteries that are offered by Losi are LOSB9950 6V 1100mAh NiMH Receiver
Pack or LOSB9820 7.4V 2000mAh 2C LiPo Receiver Pack. Please note that a voltage regulator will be needed if you choose to use a Lithium Polymer
(LiPo) receiver pack. Losi offers voltage regulators with a switch, LOSB9608 and without a switch, LOSB9609.
Droop:
Always measure the droop of the 8IGHT 2.0 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. More droop (travel) in the front will have more on-power steering and allow the buggy to roll more on the rear
when on throttle. More droop (travel) in the rear will increase off-power steering and allow the buggy to roll on the front when off throttle. More front
and rear droop will accelerate better in bumps when going straight, but can cause the buggy to traction roll in rough turns. Less front and rear droop
will slide over bumps better in turns and may be better on high-speed and high-traction tracks.
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 will increase off-power steering and make the vehicle more aggressive; however you may lose some consistency. More
camber gain is good on small tight tracks. We have found that running less camber gain in the front suits the car the best for consistency and steering
balance. On the 8IGHT 2.0 we offer a longer camber link on the spindle carrier. A longer front camber link will make the vehicle feel stiffer and this will
keep the buggy flatter with less roll and increase high-speed steering. A short front camber link will roll more and make the vehicle more aggressive.
Too short of a front link may make the vehicle feel twitchy.
Rear Camber Links:
The 8IGHT 2.0 now has only three camber locations on the rear tower, however, we have added another inside hole on the rear hub. The stock
camber link setup for the 8IGHT 2.0 is location #2 on the tower and B in the hub. By using a longer rear camber link you will have less roll and
improve stability and traction. A shorter rear camber link will have more roll and increase steering and better handling in the bumps. Running “A” in
the rear hub will generate more corner rotation entering the turn, but decrease steering on exit. Running “B” in the hub will be more stable entering
the turn and increase steering on exit.
Pistons:
Generally smaller hole pistons, #56, have stiffer damping, slower weight transfer, slower response, and will land large jumps better. Larger hole
pistons, #54, have softer damping, increased traction, quicker weight transfer/response, and bottom out easier off large jumps.
Shock Oil:
Lighter shock oil has more overall traction and responds quicker. Thicker oil has less overall traction and reacts slower. On high bite/smooth tracks,
thicker oil is easier to drive. Make sure you adjust oil when there is a drastic temperature change (20-25 degrees). If it gets cold outside you need to go
to lighter shock oil. If it gets hotter outside you need to go to thicker weight shock oil.
Front Toe:
You never want to run toe-in on the front of the 8IGHT 2.0. Front toe-in (longer steering rods) decreases steering response entering and in the middle
of the turn but will increase on power steering. Toe-out (shorter steering rods) increases steering response when entering the turn and increases
straight line stability, however, it will decrease on power steering.

37
 SETUP GUIDE
Rear Toe-in:
The 8IGHT 2.0 is equipped with 3 degrees of toe-in per side. Less rear toe-in will increase the wheel base of the buggy and decrease forward
traction, but will increase top speed and side traction in the middle of a turn. More toe-in will increase forward traction, have more off-power
steering and less side traction.
Wheel Base:
The 8IGHT 2.0 is equipped with a long wheelbase. A shorter wheelbase (spacers behind the rear hubs) increases on-power traction, rear weight
transfer, and has more off-power steering. A shorter wheelbase is better on tight or slick tracks. A longer wheelbase (spacers in front of the rear
hubs) decreases off-power steering, is more stable, better in bumps, and has more on-power steering.
Sway Bars:
The 8IGHT 2.0 is equipped with 2.3mm sway bars on the front and rear. A thinner front sway bar increases front off-power traction, but has less
on-power steering. A thicker front sway bar decreases front off-power traction making the steering smoother entering the turn, but has more on-
power steering. A thinner rear sway bar increases rear traction and decreases on-power steering. A thicker rear sway bar increases stability in the
middle of the turn and increases on-power steering. Thicker sway bars are more stable on high-speed, high-traction tracks.
Clutch:
On new clutch bells make sure to clean the inside of the clutch bell with scouring pad or fine sand paper to improve the break-in period. Softer
springs engage at a lower rpm and have a smoother power band. If the engine doesn’t have enough low-end power try running more preload
(spring with more angle) or a stiffer spring. Stiffer springs engage at a higher rpm and hit much harder. If the springs are too stiff it will cause the
clutch to slip.
Plastic vs. Aluminum Clutch Shoes:
We have found the two plastic and two aluminum clutch setup to work best on most tracks, but if the track is very loose, rough, and doesn’t have
jumps that are difficult to get over, four plastic shoes will allow more slip and smoother acceleration. Running all four aluminum clutch shoes will
have the most punch, but isn’t as good on slick, rough tracks. Our recommended clutch setup is two aluminum shoes with gold springs and two
plastic shoes with green springs. Whenever you need to rebuild your clutch we recommend the following tips. First of all, be sure to clean all parts
with Losi Nitrotec™ Spray Cleaner (LOSA99217) to ensure there is no oil or debris on any of the parts. Cleaning will include all clutch parts including
the clutch bearings. We like to spray out the clutch bearings to ensure that there is no grease slung from the bearing at high rpm which would
cause premature clutch wear or slippage. When reinstalling the clutch pins we recommend NOT using any type of Losi-Lok on the clutch pins. By
using Losi-Lok on this part, it only makes it difficult to remove the pins. Once the new shoes are installed, pull back each clutch shoe 1mm to make
sure they spring back to position to ensure proper movement. You will also want to make sure the clutch bell has anywhere from .25mm to .50mm
of movement and spins freely on the crank shaft. You can use Losi’s Metric Shim Set, LOSA6356 to dial this in properly. Now that your clutch is fully
rebuilt it is time to break it in. This is done by starting your buggy and having it idle on the ground. While firmly holding the vehicle down, apply ½
throttle for three seconds. Repeat this three times to fully seat in your new clutch.
Here is a layout of clutch setups ranging from softest to hardest in acceleration

Differentials:
The 8IGHT 2.0 comes equipped with 5000 wt in the front and center diff, and 2000 wt in the rear diff. Thinner front differential oil increases off-
power steering, but if the oil is too thin the steering will become grabby and inconsistent. Thicker front differential oil increases off-power stability
and increases on-power steering. Thinner center differential has less forward drive, can unload more under acceleration and is easier to drive on
rough and slick tracks. Thicker center differential has more acceleration, increases on-power steering, and less off-power steering. Thicker center
differential is better on high bite/smooth tracks. Thinner rear differential has more corning traction and increases steering in the middle of the turn.
Thicker rear differential has less steering in the middle of the turn and more forward traction.

 SETUP GUIDE
Shock Mounting Positions:
More inclined (moving the shocks in on the tower) has softer initial damping and is more forgiving. Less inclined (moving the shocks out on the
tower) makes the car more responsive and is better for technical tracks.
Ackerman:
A long Ackerman plate will have smooth off-power steering and is more forgiving. The long Ackerman plate will have more steering on-power. A short
Ackerman plate responds quicker and has more steering in the middle of the turn. A short Ackerman plate is better suited for tight technical tracks.
Camber:
More negative camber in the front has more steering and is more responsive.
Less negative camber in the front will have less steering and will be smoother.
More negative camber in the rear will have less rear traction, but will increase on-power steering and will be less grabby in bumps. Less negative
camber in the rear will have more rear traction and make the rear of the buggy stay flatter, but if traction is lost it will be more violent. To ensure your
8IGHT 2.0 has the correct camber we recommend using our Losi Camber Gauge (LOSA99172).
Fuel Tank:
Your 8IGHT 2.0 comes preinstalled with a fuel tank insert to meet ROAR and RC Pro Series 125cc fuel tank rules. If you are not racing your 8IGHT 2.0
where these rules apply, you can remove the insert to allow for an additional 5cc of fuel and longer run time. Also included in your 8IGHT 2.0 is an
EFRA Fuel Kit. This should be used at all EFRA races to ensure your fuel tank volume will not change during racing. The EFRA Fuel Kit ensures that the
fuel line and clunk does not come out of the tank, increasing fuel volume. Below is a diagram on how to install the EFRA Fuel Kit.

Gearing:
The stock gearing for the 8IGHT 2.0 is 13/48. If you are running on a large sweeping track and need more top speed, a 14-tooth clutch bell (LOSA9117)
is recommended.
Brake Setup:
The standard brake bias for the 8IGHT 2.0 is 60% rear - 40% front. If you need the buggy to rotate more under braking, adjust the linkage for less front
brake. If the buggy is loose entering turns under braking, adjust the linkage for less rear brake or more front brake.
Outdrives and Traction:
When your 8IGHT 2.0 is new it will have a lot of chassis roll and be a little loose on throttle due to lack of friction in the out drives and crossbones.
After about 45-60 minutes of running, the 8IGHT 2.0 will gain traction and stability. Once your 8IGHT 2.0 is broken in, replacing the out drives and
crossbones with new parts will have more corner speed.
Bump steer:
Running the bump steer ball down you will have smoother steering in the middle of the turn. With the bump steer ball up, this will increase steering
in the middle of the turn.
Rear Squat:
The 8IGHT 2.0 comes with three degrees of anti-squat. Running less anti-squat will have less off-power steering and roll (side to side) more on the rear.
Less anti-squat will accelerate better in small bumps. More anti-squat will have more support (side to side) and be better on rough tracks with big
jumps.
Ride Height:
Measuring from a flat surface to the bottom face of the chassis, adjust the front of the chassis with 27mm of ride height and 29mm in the rear. We
have found the 8IGHT 2.0 handles best when the front ride height is 1mm to 2mm lower or at least level than the rear of the truck. To measure your
ride height properly we recommend using the Losi Ride Height Gauge (LOSA99173).
