Safety Precautions

We hope you operate this RC model in a safe, reasonable and
cautious fashion in order to enjoy your vehicle. Should you operate
this vehicle without a cautious and reasonable approach it may
result in serious injury and/or property damage. Only you can
control and make certain that safety precautions and instructions

are followed.

General:

• The 1/10 Strike SCT is not a toy. This product is not
intended for use by children without direct adult supervision.

• This RC vehicle is not intended for use on public highways

or roads.

• Avoid an area that has many pedestrians or crowds of

people.

• Keep in mind that this vehicle is radio controlled and can
experience moments of radio loss or interference, so

provide for a margin of error at all times.

• Please be aware that the motor and batteries of this RC
vehicle will get HOT during each use. Be careful not to burn
yourself.

Electronic Speed Control (ESC):

• Read all safety precautions prior to each use.

• Never leave the vehicle/ESC unsupervised while it is
switched on, in use or connected to a power source. If there
is a short-circuit or product defect, it could result in fire.

• If there are exposed wires, do not use the ESC until you
have installed shrink-wrap or replaced the wire.

• Disconnect the battery from the ESC after use.

• The ESC is water-resistant, but should not be submerged or
exposed to long periods of moisture.

• Do not attempt to use more than a 2S LiPo battery or

more than a 7-cell NiMH battery; doing so will damage
the ESC and could result in fire.

• Always turn on the transmitter first then the ESC to prevent
an out-of-control vehicle.

• When setting your Electronic Speed Controller:

º Please disconnect motor or remove the pinion gear

during ESC setup or calibration functions.

º Keep loose clothing, hair, gloves and fingers away

from moving parts at all times.

º Rubber tires can cause severe injury if there is a

failure while running the vehicle while on a stand or

when being held. Ensure rubber tires are securely
mounted to the rims and if not, re-glue them and
check them often for security.

Batteries and Charging:

The 1/10 Strike SCT uses rechargeable batteries such as NiMH
or LiPo. These batteries require special handling to preserve
performance and last a long time. Read all instructions and
precautions that are provided with the batteries intended to be
used in the 1/10 Strike SCT.

• Read all instructions provided by the manufacturer of the

batteries.

• Responsible adult supervision is necessary while charging

batteries.

• Always check to ensure the polarity of battery connection is

correct.

• Never leave batteries unattended while charging.

• Never charge a battery while it is installed in the 1/10 Strike

SCT.

• Do not charge any battery that appears to have any

damage.

• If there are exposed wires do not charge or use the battery
until you have installed shrink-wrap or replaced the

complete wire.

When charging NiMH batteries, select a charger to meet your
requirements. Chargers can be of two primary types for their
source of power; a 100-240V wall charger, or one which requires
a 12V power supply. Follow the charger manufacturer’s instruc-

tions and precautions during each use.

NiMH battery charger with automatic “peak detection” or

LiPo-compatible charger recommended.

MultiPro™ Intelligent Balance Charger (LOSB9606)

AC Adapter (LOSB9604) required for AC operation

Using Your Charger:

If you do not yet have a charger, a peak detecting charger will
provide the performance required and take care of your expensive
batteries.

A popular choice for a charger would be a peak detection charger
that can be plugged into a household AC wall socket. The peak
detection portion of the charger monitors the battery charging and
will automatically shut off upon full charge.

Other peak detection chargers require a 12V power source to
charge your batteries. You would need to use or purchase a
hobby grade 12V power supply before charging.

Vehicle Battery

(6-Cell 7.2V “Stick Pack”)

LOSB9903

If you are going to be using a charger other than a peak detection
charger it is important to have your battery fully discharged prior
to recharging. Many of these have a timer that allows you to set
the amount of charge time. If the battery was not fully discharged
from prior use, you can potentially overcharge your battery pack.

If you are using a LiPo battery be sure to consult the
manufacturer’s suggestions for an appropriate LiPo-compatible
charger. Chargers designed for NiMH cells only should never be
used to charge your LiPo batteries and could result in serious
injury.

Do not charge any battery unattended, and monitor for heat build
up. If the battery pack is more than warm to the touch immediately
discontinue charging.

Read all safety precautions supplied by the charger manufacturer,
and also any from the battery manufacturer.
