Basic Tuning Adjustments
Adjusting the Spur Gear/Clutch Bell Gear Mesh
The ideal spur gear/clutch bell gear mesh
for Slayer is 0.1mm. To set the gear mesh,
place a strip of standard letter/A4 size
copy or printer paper (about 0.1mm thick)
between the mating teeth. Loosen the two
horizontal engine mount screws and slide
the engine mount up to push the clutch bell
gear against the spur gear so that the that
the paper is not too tight to pull out or too
loose that it will fall out. Tighten the two
horizontal engine mount screws securely.
When the paper is removed, you should feel
only the slightest amount of play between
the gears (almost none) and there should be
no binding or friction.
Changing the Spur Gear
1.
Remove the four cap head screws that
secure the engine to the engine mount.
2.
Remove the button head screw that
secures the pipe hanger to the rear
body mount.
3.
Carefully remove the engine and exhaust
system from the spur gear area to allow enough
room to remove the spur gear.
4.
Remove the three screws on the slipper clutch
assembly using a 2.5mm hex wrench. Slide the
spur gear off of the slipper shaft. If the spur gear
is too tight on the shaft, gently pry on the back
of the gear with a flat screw driver to loosen it.
Repeat the above steps in reverse order to install the new spur gear.
STEERInG SYSTEM
Slayer 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 Servo Horn 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. 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 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.
