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.

Batteries and Battery Charging

Your model uses rechargeable batteries that must be handled with 
care for safety and long battery life. Make sure to read and follow 
all instructions and precautions for charging and maintaining the 
batteries. It is your responsibility to charge and care for the battery 
packs properly. In addition to your battery and charger instructions, 
here are some more tips to keep in mind.
• Do not charge batteries inside of an automobile. Do not charge 

batteries while driving in an automobile. The charger is equipped 
with a long cord intended to allow the battery to be charged 
outside of an automobile when using the automobile’s auxiliary 
power socket. If the cord will not reach outside of the automobile, 
find another power source.

• Never charge batteries on wood, cloth, carpet or on any other  

flammable material.

• Do not operate the charger in a cluttered space, or place objects 

on top of the charger or battery.

• If a battery gets hot to the touch during the charging process 

(temperature greater than 140°F / 60°C), disconnect the battery 
fromthe charger and discontinue charging immediately.

• Always store battery packs safely out of the reach of children and 

pets.

• Do not short-circuit the battery pack. This may cause burns and 

severe damage to the battery pack and create the risk of fire.

• Do not expose the charger to water or moisture.
• Do not disassemble the charger.
• Use the supplied charger to charge the included battery. See 

“Charging the Battery Pack” on page 12. 

• Never leave batteries to charge unattended.
• Remove the battery from the model while charging.
• Always unplug the battery from the electronic speed control 

when the model is not in use and when it is being stored or 
transported.

• Allow the battery pack to cool off between runs (before charging).
• Children should have responsible adult supervision when 

charging and handling batteries.

• Do not use battery packs that have been damaged in any way.
• Do not use battery packs that have damaged wiring, exposed 

wiring, or a damaged connector. 

• Do not burn or puncture the batteries. Toxic materials could be 

released. If eye or skin contact occurs, flush with water.

• Store the battery pack in a dry location, away from heat sources 

and direct sunlight.

• Nickel Metal Hydride batteries must be recycled or disposed of 

properly.
