MAINTENANCE TIPS

BEFORE EACH RUN
1. Check to make sure that all screws are tight and there
are not any screws missing.
2. Before running always check the condition of your radio
system batteries and replace/recharge if necessary.
3. Check to make sure that all of the moving parts of the
Nitro Evader move freely and do not bind.
4. Check the fuel tank and fuel lines for leaks.
5. Before starting the engine, turn on the radio and make
sure the servos move easily and in the proper direction.
6. Inspect the air cleaner for a torn or damaged element. Also
look for dirt in the air cleaner element and wash it if necessary.
7. Check for broken or damaged parts. Replace any
broken or damaged parts before running the Nitro Evader.
Running of the Nitro Evader with broken or damaged parts
could result in damage to other parts.
8. Check to make sure that all wires are properly connected.
AFTER EACH RUN
1. Clean any large globs of dirt or debris from the chassis
and moving parts.
2. Drain the fuel tank of any leftover fuel. DO NOT return
the fuel to your fuel jug.
3. Check for any broken or damaged parts. This way parts
may be replaced before the next run.
4. Put some after-run oil in the carburetor 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.
AFTER EVERY 10 RUNS
1. Check to make sure that the bearings are free of dirt
and debris, and roll smoothly.
2. Check the shocks for oil leakage. If the shocks have
leaked any shock fluid out, you should properly refill the
shocks for best performance.
3. Make sure the servo saver moves freely and does
not bind. This will help prevent stripping of the servo
during running.
4. Check for proper gear mesh between the spur and
clutch bell.

TUNING GUIDE

When tuning the Nitro Evader make sure that you have
equal lengths from one side to the other on the shocks,
camber rods and steering rods. Also, make sure to have the
shock pre-load adjusters at the same setting from left to
right. They do not have to be the same front to rear.
CASTER
Caster refers to the angle at which the kingpin is at in
relation to the surface when viewed from the side. 0 degrees
of caster means that the kingpin is straight up and down.
The Nitro Evader BX comes stock with 30 degrees of caster
and is not adjustable.
CAMBER
2˚ Negative Camber
Camber refers to the angle at which the tire and wheel ride
in relation to the ground when viewed from the front or rear.
Negative camber is when the tire and wheel lean inward and
positive camber is when the tire and wheel lean outward.
Typically you want 0 to -2 degrees of camber. Never put in
positive camber. Make sure that both sides are equal.
FRONT TOE-IN AND TOE-OUT
1˚
Front wheels pointed towards each other.
Toe-in and toe-out refers to the angle at which the tire is at
when view from above. Toe-in increases stability under
acceleration . However, toe-in also decreases steering when
entering a corner. Toe-out will increase steering into corners,
but will decrease the overall stability during acceleration. The
front typically is set-up with 0 to -2 degrees of toe-in.
