CHECKLIST
BEFORE RUNNING YOUR NEW
8IGHT-E 2.0
OFF-ROAD RACING BUGGY
for the first time, you should run down the following checklist in order and
complete the listed tasks. We’re sure you’re anxious to get out and run your new
8IGHT-E 2.0
now that it’s built, but please note that fine-tuning of the
initial setup is an essential part of building a high-performance racing buggy such as your new
8IGHT-E 2.0
. Following this simple Checklist and the Team
Tips will help to make the first run with your new car much more enjoyable.
1. Break in the differential:
While holding the chassis with
only
the left side tires firmly 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 firmly 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 27mm from the ground in front and 29mm in the rear by adjusting
the shock adjustment nuts, effectively 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, increasing negative camber.
Set the front tires to have 1 degree of negative camber and ensure
that they are adjusted equally, left to right. Set the rear tires to have
2 degrees of negative camber and ensure that 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 degrees of toe-out. Refer to the Setup Guide for more information
on toe-in/out.
6. Charge a battery pack:
Charge a battery pack as per the battery manufacturer's and/or
charger manufacturer's instructions. Never plug the battery into the
speed controller backwards as this will damage the speed controller.
7. Adjust the electronic speed control (ESC):
Follow the manufacturers instructions, adjust your speed control
and set the throttle trim so that the buggy does not creep forward
when no transmitter input is applied. Make sure there is not much
brake being applied when the throttle input is at the neutral
position. Some speed controls have a high/low setting for brakes.
8. Set the transmitter steering trim:
The steering trim tab on the transmitter should be adjusted so
that 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 that 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 that the brakes are
not “dragging” in the neutral position.
