BEFORE RUNNING YOUR NEW 8IGHT OFF-ROAD RACING BUGGY for the fi rst time, you should run down the following check-
list in order and complete the listed tasks. We’re sure you’re anxious to get out and run your new 8IGHT now that its built, but please note
that fi ne tuning of the initial setup is an essential part of building a high performance racing buggy such as your new 8IGHT. Following this
simple Checklist and the Team Tips will help to make the fi rst run with your new car much more enjoyable.
1. Breaking in the Differential:
While holding the chassis with only the left side tires fi rmly on
the ground, give the car about one eigth throttle, for 30 seconds.
The right side tires should spin freely during this time. Repeat
this with only the right side tires held fi rmly to the ground, al-
lowing 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 free-
ly. 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 chas-
sis 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 ad-
ditional information on ride height adjustment.
4. Set the camber:
Adjusting the camber tierod length changes the amount of cam-
ber. Use the Team Losi wrench to adjust the tierods once in-
stalled. Rotating the tierods towards the front end of the vehicle
will shorten the length, increasing negative camber. Rotating
the tierods towards the back of the car will lengthen them, in-
creasing 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 tierods so that when the servo is cen-
tered on the transmitter, the front tires are both pointing slightly
out with 1 degree 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
that the car rolls straight when you are not touching the steering
wheel/stick. If the servo and steering link were installed cor-
rectly, 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 F-03. Make sure the throttle trim is set
so that 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
that the the brakes are not dragging in the neutral position. The
idle adjustment screw on the carburetor should be set at approxi-
mately 1mm open. When the throttle trigger is pulled back to the
maximum, the carburetor is fully opened
