BEFORE RUNNING YOUR NEW TRIPLE-X for the first time, you should run down the following checklist — in
order
—
and
complete
new Triple-X now that it's built, but following this simple checklist will help to make your first run with your new car
much more enjoyable.
1. Adjust the differential
See About The Differential in the tips section.
2. Adjust the slipper
See Adjusting The Slipper in the tips section.
3. 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.
4. Set the rear ride height
The rear ride height should be set so that the dogbones
are level with the surface. See the Rear Ride Height
section of the tips.
5. Set the front ride height
The front ride height should be set so that the front
suspension arms are level with the surface. See the
Front Ride Height section of the tips.
6. Adjust the camber
The front camber should be set to about 1/2 degree
of negative camber (top of tire points in) at ride height.
Adjust the front camber with the tires turned straight
ahead. The rear camber should also be set to have
about 1/2 degree of negative camber at ride height.
See the Camber section of the tips.
TIPS AND HINTS FROM THE TEAM
About The Differential Never allow the diff to slip; that's what the slipper is for. Before trying to adjust your diff,
you need to tighten the slipper until the spring is fully compressed. Next, hold the spur gear and right rear tire, then try
turning the left rear tire forward. It should be very difficult to turn the left rear tire. If the tire turns easily, the diff is too
loose. To tighten the diff, line up the slot in the diff screw with the groove in the left outdrive. Place the 1/16" Allen
wrench through both of these slots. This will lock the diff screw and the outdrive together. While holding the Allen
wrench in place, turn the right rear tire forward about 1/8 of a turn. Check the differential adjustment again and repeat
the tightening process as necessary until the differential is no longer slipping. The final differential adjustment check
should be made by placing the car on carpet, grass, or asphalt and punching the throttle. The differential should not slip.
If it does, tighten the diff in 1/8-turn increments as described above until the slippage stops.
Once the diff has been adjusted, it should still operate freely and feel smooth. If the diff screw starts to get tight
before the diff is close to being adjusted properly, the diff should be disassembled and inspected; you may have a
problem with the differential assembly. Refer to the assembly instructions to ensure that the diff is properly assembled
and that all parts are properly seated in the assembly.
There are a few things you should know about differentials. First, when rebuilding your diff, you should always
replace the small, 4-40 locknut. Second, after the diff has been run a time or two, it is not uncommon for the balls to seat
into the rings and create a slightly loose adjustment. So, after your first and second runs, check the adjustment to avoid
slippage. Third, remember: Never let the diff slip. Doing so can damage the diff balls, rings, and gear. Always make sure

7. 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
pointing straight. It is recommended that you start
with the front toe-in set to zero (no toe-in or toe-out).
8. 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.
9. Adjust the speed control
Following the manufacturer's instructions, adjust your
speed control, and set the throttle trim on your trans-
mitter 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.
10. Set 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 was
installed correctly, as per Tables 53A and 53B, the
wheels should turn equally to the left and right. If
this is not the case, refer to Table 53A &B and ensure
that the steering servo and rod were properly installed.
