FINAL CHECKLIST
BEFORE RUNNING YOUR NEW XXX-S SPORT for the first time, you should run down the following checklist in
order and complete the listed tasks. I'm sure you're anxious to get out and run your new
XXX-S Sport, but following
this simple checklist will help to make your first run with your new car much more enjoyable.
1. Adjust the differential
While holding the chassis with only the left side tires
firmly on the ground give the car about a quarter throttle
for ten seconds. The right side tires should spin freely
during this time. Repeat this with the right side tires
held firmly to the ground allowing the left tires to spin.
Feel the diff action and tighten slightly if necessary.
2. Check for free suspension movement
All suspension arms should move freely. Any binds will
cause the car to handle poorly. The steering should also
operate very freely.
3. Set the ride height
Adjust the chassis ride height to 1/4" (6mm). See the
tips section for additional information on this.
4. Set the camber
Both front and rear tires should have 1 degree of
negative camber (Top of the tire leans in). It is critical
that both front tires and both rear tires be adjusted the
same.
5. Set the front toe-in
Adjust the front tie rods so that, when the steering is
straight on the transmitter, the front tires are both point-
ing straight. It is recommended that you start with the
front toe-in set to zero (no toe-in or toe-out).
6. Charge a battery pack
Charge a battery pack as per battery manufacturer's and/
or charger manufacturer's instructions so that
radio adjustments can be made. Never plug the battery
backwards into the speed control.
7. Adjust the speed control
Following the manufacturer's instructions, adjust your
speed control, and set the throttle trim on your ESC so
the the car does not creep forward when not applying
throttle. Make sure that there is not too much brake
being applied when the trigger/stick is in the neutral
position. Some speed controls have a high/low setting
for the throttle.
8. Set transmitter steering trim
The steering trim tab on the transmitter should be ad-
justed so that the car rolls straight when you are not
touching the steering wheel/stick. If the servo was in-
stalled correctly, as per Tables 21A and 21B, the wheels
should turn equally to the left and right. If this is not
the case, refer to Table 21B and ensure that the steer-
ing servo and rod were properly installed. Make sure
the throttle trim is set so that the motor does not run
when in the neutral position. You may wish to run one
"click" of brake to be safe.
TIPS AND HINTS FROM THE TEAM
Before you start making changes on your XXX-S Sport, you need to make a few decisions. Tires and how they are set-up
have a tremendous impact on overall performance. Before you start making changes on the chassis take a moment to observe
a few of the fastest cars and what type of tire and inner liner they are running. Also note the wheel diameter and width as this
can also effect how the tires perform. When making chassis changes you should first decide where you feel the car needs to
be different. This is commonly referred to as changing the "balance". Since the XXX-S Sport is a four-wheel drive chassis you
have two ends of the car working separately yet together. First decide if the front of the car needs to be adjusted or the back.
You will want to work with the rear if the car enters the turn with the front end sticking and tracking well while the rear end
either does not want to follow or simply doesn't know what it wants to do. The opposite is true if the rear end seems to want
to push the front end through the corners or the front dives into the corner uncontrollably. You will notice that several
different adjustments have similar effects on the handling as well. You will find the best adjustment will become a personal
decision based on the "feel" that each of these adjustments yield. This also reflects on the "balance" we referred to earlier.
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 stock position and try something else. Team Losi's development team has put hundreds of hours on the XXX-S Sport
to arrive at the set-up we put in the instruction manual. If you find that you have lost the "handle" go back to the kit (stock)
set-up as this has proven to be reliable, consistant, and easy to drive.
