Toe-In/Toe-Out: This refers to the angle of the front
tires when viewed from above when the suspension
arms are level. If the fronts of the tires angle in, it is
called “toe-in” and if the fronts of the tires angle out, it
is called “toe-out.” This is adjusted by lengthening or
shortening the steering rods - the rods that run
between the front hub and the servo saver. Normally a
small amount of toe-in is used to make the buggy track
straight at high speed. Too much toe-in will make the
buggy difficult to turn as well as reduce the overall top
speed because of tire scrub. Sometimes a small
amount of toe-out will be used to help the steering. As
a general rule use a small amount of toe-in.
Camber: Camber is the angle of the tops of the tires
when viewed from the front. Negative camber is when
the tops of the tires are angled towards the center of
the buggy. Positive camber is where the tops of the
tires are angled away from the center of the buggy.
Positive camber is very rarely used, if ever. A small
amount of rear negative camber is helpful to increase
traction in the rear. Negative camber at the front will
increase stability. Camber adjustments can be made
on the Axis by turning the “camber rods,” which are the
upper links on the suspension. Lengthening the
camber rod will add positive camber and shortening
the camber rod will add negative camber.
Shocks: Changes in shock oils, springs, and pre-load on
the springs can dramatically change the way the car
handles. A thicker shock oil will make the buggy turn
faster but reduces overall traction and handling over
bumpy surfaces. Thinner oil will increase traction at the
expense of steering response and the car will tend to roll
more. In general, shock oils between 20 and 40 weight
will be best for your buggy. You should experiment some
to see what oils work best for your track and driving style.
Shock springs affect the rate that the suspension
rebounds from a bump. We have supplied soft springs
that work under most conditions. Pre-load on the springs
means that the springs are already compressed some
so that the suspension will rebound faster. Sometimes
you will want to pre-load one side when the track has
turns all or mostly in one direction, for instance an oval
track. It will also increase the ride height.
Before Each Run
• Check for loosened screws on the buggy. Engine
vibration will loosen some of the screws, particularly
in the engine mount area. Use thread lock on screws
that thread into metal parts or use a metal nut.
• Inspect the air cleaner for a torn or damaged
element. Also look for dirt in the air cleaner element
and wash it if necessary.
• Check the suspension and drive train for binding.
• Inspect all of the wires for damage. Also check the
connectors to make sure all of them are tight and in
the proper place.
• Check the fuel tank and fuel lines for leaks.
• Before starting the engine, turn on the radio and
make sure the servos move easily and in the right
direction.
• Before running always check the condition of your
radio system batteries and replace/recharge if
necessary.
After Each Run
• Drain the fuel tank of any leftover fuel. DO NOT
return it to your fuel jug.
• Put some after-run oil in the carb and turn the
flywheel several times to work the oil into the
engine. This will protect the engine from rusting,
especially when stored for a long period of time.
• Check again for loosened screws.
• CLEAN the buggy. Wipe off any oils that have
collected on the chassis, engine end exhaust. Oils
will attract dirt on the next run.
