Toe In
Set the steering trim on your transmitter to neutral. Now, adjust
your tie rods so that both wheels are pointing straight ahead
and are parallel to each other (0 degrees toe in). This will ensure
the same amount of steering in both directions. If you run out of
adjustment, then the steering servo will have to be re-centered
(see centering your servos on page 41).
Fine Tuning the Shocks
The four shocks on your Nitro 4-Tec have
the most influence on its handling.
Whenever you rebuild your shocks, or
make any changes to the pistons, springs
or oil, always do it carefully and in pairs
(front or rear). Piston head selection
depends on the range of oil viscosities
that you have available. For example,
using a one-hole piston with a
lightweight oil will give you the same
dampening as a two-hole piston with
heavier oil. We recommend using the
one-hole pistons with a range of oil
viscosities from 10W to 50W (available
from your hobby shop). The thinner
viscosity oils (30W or less) flow more smoothly and are more
consistent, while thicker oils provide more dampening. Use only
100% pure silicone shock oil to prolong seal life.
The ride height for Nitro 4-Tec can be adjusted by adding or
removing the clip-on spring pre-load spacers. Instead of adding
spacers to increase stiffness, use stiffer springs. Adjust the ride
height so that the suspension arms are slightly above being
parallel to the ground. Note that changes in ride height will
occur when the changes in damper angle or spring rates are
made. You can compensate for ride height changes by changing
the pre-load spacers on the dampers. Generally speaking, ride
height should be set as low as possible without causing
significant bottoming of the chassis. Also, in order not to disturb
cornering balance, front and rear tire height diameters should
be equal. Replace excessively worn tires.
Belt Tension Adjustments
The Nitro 4-Tec’s front and middle
drive belts are designed to have a
high initial tension. During the break-
in period, the drive belts and pulleys
will “wear in” and the belt tension will
gradually decrease. The front and
middle belt tensions can be tightened
by inserting shims under the front
bearing block. Do not tighten the
front belt tension unless there is more
than 0.25 inch (6mm) deflection at the
center of the belt (see drawing). To
tighten the belt, add the 0.1mm shim first and retest. If the belt
is still loose, remove the 0.1mm shim and add the 0.2mm shim
and retest. The rear belt tension is adjustable via belt tension
cams in the right and
left rear side plates. The
rear belt in the Nitro
4-Tec transmits most of
the engine’s power.
Because of the high
loading of the rear belt,
the tension should be
checked every 3-4
hours (20-25 tanks of
fuel) of running. If the rear belt can be deflected more than 0.25¨
(6mm) (see illustration), the belt tension cams should be rotated
rearward to the next eccentric slot.
At no time should
the body of the car
strike the ground or
interfere with the suspension
or tires. Either situation will
cause extremely
unpredictable handling.
