Setting Up the Antenna
1. Thread the antenna wire into
the supplied antenna tube (the
antenna tube can be found in the
documents bag).
2. Insert the base of the tube into the
antenna mount. Take care not to crimp
the antenna wire.
3. Using the supplied 1.5mm "L" wrench,
thread the 1.5mm set screw into the
opening next to the antenna. Tighten the set screw until it is
flush with the top of the opening.
4. If necessary, fold the top of the antenna wire over the top of
the antenna tube. Slide the antenna tip onto the top of the
antenna tube. Do not cut or shorten the antenna wire.
5. The receiver antenna installation is complete.
Programming the VXL-3s Speed Control
The Slash 4x4 is equipped with the high-performance Velineon
brushless power system. Before operating your model, you
will need to calibrate the speed control to your transmitter, as
described below. The Velineon VXL-3s speed control also features
three driving profiles and Low-Voltage Detection for use with
lithium polymer (LiPo) batteries. Note that the speed control has
been adjusted at the factory specifically for the Platinum Edition,
using the following settings:
Driving Profile 1: Sport Mode - This profile enables full reverse
throttle control for maximum versatility and fun with your Slash
4x4. If you plan to race your Slash 4x4, be aware that most tracks
do not allow the use of reverse in competition. If your track
does not allow reverse, follow the steps on page 17 of the Slash
4x4 Owner's Manual to select profile 2, Race Mode. Race Mode
eliminates reverse, but still gives fully proportional braking control.
Low-Voltage Detection: ACTIVATED - This is the required
setting for use with LiPo batteries. When switched on, the speed
control's LED will glow green, indicating Low-Voltage Detection
has been enabled. The Low-Voltage Detection circuitry
constantly monitors the battery voltage. When the battery
voltage begins to reach the minimum recommended discharge
voltage threshold for LiPo battery packs, the VXL-3s will limit
the power output to 50% throttle. When the battery voltage
attempts to fall below the minimum threshold, the VXL-3s will
shut down all motor output. The LED on the speed control will
slowly blink red, indicating a low voltage shutdown. The VXL-3s
will stay in this mode until a fully charged battery is connected.
If you wish to operate your model using a NiMH battery,
Low-Voltage Detection may be disabled to achieve maximum
run time. Page 16 of the Owner's Manual explains how to
disable Low-Voltage Detection. When the speed control
is turned on, its LED will glow red, indicating Low-Voltage
Detection is disabled. Never use LiPo batteries while Low-
Voltage Detection is disabled.
VXL-3s Setup Programming
(Calibrating your ESC and transmitter)
Read through all of the programming steps before you begin. If
you get lost during programming or receive unexpected results,
simply unplug the battery, wait a few seconds, plug the battery
back in, and start over.
SLASH 4x4 PLATINUM EDITION
1. Connect a fully charged battery pack to the VXL-3s.
2. Turn on the transmitter (with the throttle at neutral).
3. Press and hold the EZ-Set button (A). The LED
will first turn green and then red. Release the
EZ-Set button.
4. When the LED blinks RED ONCE, pull
the throttle trigger to the full throttle
position and hold it there (B).
5. When the LED blinks RED TWICE, push
the throttle trigger to the full reverse
and hold it there (C).
6. When the LED blinks GREEN ONCE,
programming is complete. The LED will then
shine green or red (depending on low-voltage
detection setting) indicating the VXL-3s is on
and at neutral (D).
Tuning and Maintaining the Shocks
Slash 4x4 features high-performance Big Bore shocks that utilize
friction-reducing titanium nitride shafts and hard-anodized
bodies with PTFE-coated bores to provide the ultimate in
precise damping control. The shocks are filled with 50W silicone
fluid in the front and 40W fluid in the rear. You may wish to install
lower-viscosity ("thinner") or higher-viscosity ("thicker") fluid to
alter damping performance to suit your track, terrain, or driving
style. Damping can also be altered by changing the pistons inside
the shocks.
Whenever you rebuild your shocks, or make any changes to the
pistons, springs or oil, always make changes to them in pairs
(front or rear). Piston selection depends on the range of oil
viscosities that you have available. For example, using a two-hole
piston with a lightweight oil will, at one point, give you the same
damping as a three-hole piston with heavier oil. We recommend
using the two-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 damping. Use only
100% pure silicone shock oil to prolong seal life.
Lower-viscosity fluid (lower oil weight #) = less damping force
More or larger piston holes = less damping force
In general, less damping is used on tracks or surfaces that
have lots of small bumps and irregularities that require
the shocks to extend and compress very rapidly. Reducing
damping allows the shocks to rebound more quickly after an
impact, so the shocks will be able to absorb the next impact
and allow the tires to better maintain contact with the racing
surface. Reducing damping force can also help increase
traction on "loose" or slippery surfaces.
Higher-viscosity fluid (higher oil weight #) = more damping force
Fewer or smaller piston holes = more damping force
In general, more damping is used on tracks that have large
bumps and jumps that require the shocks to absorb hard
impacts. Increased damping helps slow the compression rate to
better dissipate impact energy and help prevent the shocks from
bottoming out. Increased damping force can also help "loosen
up" your truck if you are racing on a high-traction surface and
prefer less grip to help you carry speed through corners.
