4 • SLASH 4X4 ULTIMATE
This model is not intended
for use by children under
14 years of age without the
supervision of a responsible
and knowledgeable adult.
Gearing and battery choice
(
see LiPo Batteries, right)
affect the skill level of the
model. See chart below.
All instructions and
precautions outlined in this
manual should be strictly
followed to ensure safe
operation of your model.
SAFETY PRECAUTIONS
All of us at Traxxas want you to safely enjoy your new model. Operate your
model sensibly and with care, and it will be exciting, safe, and fun for you and
those around you. Failure to operate your model in a safe and responsible
manner may result in property damage and serious injury. The precautions
outlined in this manual should be strictly followed to help ensure safe
operation. You alone must see that the instructions are followed and the
precautions are adhered to.
Important Points to Remember
• Your model is not intended for use on public roads or congested areas where
its operation can conflict with or disrupt pedestrian or vehicular traffic.
• Never, under any circumstances, operate the model in crowds of people. Your
model is very fast and could cause injury if allowed to collide with anyone.
• Because your model is controlled by radio, it is subject to radio interference
from many sources that are beyond your control. Since radio interference can
cause momentary losses of radio control, always allow a safety margin in all
directions around the model in order to prevent collisions.
• The motor, battery, and speed control can become hot during use. Be careful
to avoid getting burned.
• Don’t operate your model at night, or anytime your line of sight to the model
may be obstructed or impaired in any way.
• Most importantly, use good common sense at all times.
Speed Control
Your model’s electronic speed control (ESC) is an extremely powerful
electronic device capable of delivering high current. Please closely follow these
precautions to prevent damage to the speed control or other components.
• Disconnect the Battery: Always disconnect the battery or batteries from the
speed control when not in use.
• Insulate the Wires: Always insulate exposed wiring with heat shrink tubing to
prevent short circuits.
• Water and Electronics Do Not Mix: The speed control is waterproof for use
in mud, snow, puddles, and other wet conditions. Make certain the other
components of your model are waterproof or have sufficient water resistance
before driving in wet conditions.
• Transmitter on First: Switch on your transmitter first before switching on the
speed control to prevent runaways and erratic performance.
• Don’t Get Burned: The ESC and motor can become extremely hot during use,
so be careful not to touch them until they cool. Supply adequate airflow for
cooling.
• Use the Factory-Installed Stock Connectors: Do not change the battery and
motor connectors. Improper wiring can cause fire or damage to the ESC.
Please note that modified speed controls can be subject to a rewiring fee
when returned for service.
• No Reverse Voltage: The ESC is not protected against reverse polarity voltage.
• Always adhere to the minimum and maximum limitations of the speed
control as stated in the specifications table on page 17. If your ESC operates on
two batteries, do not mix battery types and capacities. Use the same voltage
and capacity for both batteries. Using mismatched battery packs could
damage the batteries and electronic speed control.
LiPo Batteries
Lithium Polymer (LiPo) batteries are becoming popular for use in R/C models
due to their compact size, high energy density, and high-current output;
however, these types of batteries require special care and handling procedures
for long life and safe operation.
WARNING: LiPo batteries are intended
only for advanced users that are educated on the risks associated with
LiPo battery use. Traxxas does not recommend that anyone under the
age of 14 use or handle LiPo battery packs without the supervision of a
knowledgeable and responsible adult.
Your model is able to use LiPo batteries. LiPo batteries have a minimum safe
discharge voltage threshold that should not be exceeded. The electronic speed
control is equipped with built-in Low-Voltage Detection, which alerts the
driver when LiPo batteries have reached their minimum voltage (discharge)
threshold.
It is the driver’s responsibility to stop immediately to prevent the
battery pack from being discharged below its safe minimum threshold.

WARNING! CAUTION! DANGER!
FIRE HAZARD!
Charging and discharging batteries has the potential for
fire, explosion, serious injury, and property damage if not performed per the
instructions. In addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of
fire if not properly handled per the instructions. Before use, read and follow all
manufacturer’s instructions, warnings, and precautions. Never allow children under 14 years old
to charge or use LiPo batteries without the supervision of a responsible, knowledgeable adult.
• While charging or discharging, ALWAYS place the battery (all types of batteries) in a fire
retardant/fire proof container and on a non-flammable surface such as concrete.
• ALWAYS charge batteries in a well-ventilated area.
• REMOVE flammable items and combustible materials from the charging area.
• ONLY use a LiPo balance charger with a balance adapter to charge LiPo batteries.
• If any battery or cell is damaged in any way, DO NOT charge, discharge, or use the battery.
• BEFORE you charge, ALWAYS confirm that the charger settings exactly match the battery
type (chemistry), specification, and configuration to be charged.
• DO NOT exceed the maximum manufacturer recommended charge rate.
• DO NOT disassemble, crush, short circuit, or expose the batteries to flame or other sources
of ignition.
• NEVER leave batteries unattended while charging.
