STEERING SYSTEM

Slayer Pro 4x4 uses a digital servo and a single heavy-duty servo saver
for powerful, responsive steering.

Adjusting The Steering System

1. Remove the servo horn and steering link from the servo. Disconnect
the steering link from the servo saver.
2. Adjust the steering link to be 31.7mm - use "Steering Link Length
Template" below to set length).
3. Switch on the power to the receiver and the transmitter.
4. Adjust the steering trim on the transmitter to the neutral "0" position.
5. Connect one end of the steering link to the servo saver arm and the
other end to the servo horn
6. Position the steering servo saver arm perpendicular to the centerline of
the vehicle.
7. While holding the steering servo saver arm in
the position mentioned in step 6, install the
servo horn onto the servo so the steering link
is parallel with the centerline of the vehicle.
This will automatically set the servo horn at
the 7-degree offset shown in the illustration.
If you are using an aftermarket servo, it is
important to use a servo horn designed for
Slayer Pro 4x4. Optional steering servo horns are
sold separately for use with non-Traxxas servos.

Servo Saver Tuning
An optional stiffer spring is available for the servo saver when using
servos with metal gear sets (see parts list for details). Do not use this
spring with standard Traxxas high-torque servos.
BRAKE SETUP & ADJUSTMENT
Slayer Pro 4x4 is equipped with a disc brake that rides on the yoke of
the transmission's front output shaft. The brake is preset at the factory
and should not require attention. As the brake material wears, future
adjustments may be necessary.
BASIC TUNING ADJUSTMENTS

Brake Shoulder Bolt Adjustment

The two shoulder bolts that are
used to secure the brake pads to
the transmission housing may
need to be adjusted periodically
as the brake material wears down.
They should be tightened so a 0.50mm (.020") gap exists between the
disk and the brake pad (on the transmission side). Adjust in one of the
following ways:
1. Use a 0.50mm feeler gauge between the brake pad insert
and brake disk.
2. Push the outer brake pad firmly against the inner pad with your
finger, sandwiching the brake disk between the brake calipers.
Tighten the brake shoulder bolts until they just barely touch the
brake pads. Do not over tighten these fasteners or you could damage
the brake calipers. Loosen each of the shoulder bolts by 1 turn.

Brake Linkage Adjustment

When correctly adjusted, the brake
linkage spring should barely touch the
rod guide when the servo is in neutral
position (closed throttle). This will ensure
no brake drag during operation of the
vehicle. The brake adjustment knob can
be threaded away from the spring for less
braking power if desired. Do not adjust
knob to apply pressure against the
spring while the servo is in the neutral
position. This will induce brake drag
and cause undesirable handling.
The position of the z-bend from the
factory is in the middle position of the
servo horn. Changing this position will
affect the way the brake force is applied. The brake adjustment knob
will need to be readjusted if this position is changed.
Brake Pad Wear and Replacement
During normal use the brake pads should wear at a relatively slow rate.
However, if the brake pads wear down close to the metal pad holders,
they should be replaced. Any more wear than this could cause damage
to the brake parts and improper operation of the brake system.
