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)

 

effect 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.
• Use the supplied charger to charge the included battery. See 

“Charging your 

Battery Pack”

 on page 11. 

• 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. 

• Only use approved chargers for NiMH battery packs (such as the Traxxas EZ-Peak

 

Charger, Part #2930). Do not exceed the maximum charge rate of 4 amps.

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

the battery pack.

• 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.  

Recycling Your Traxxas Power Cell NiMH Battery

Traxxas strongly encourages you to recycle your Power Cell battery when it 
has reached the end of its useful life. 

Do not throw your battery in the trash.

 

All Power Cell battery packs display the RBRC (Rechargeable Battery Recycling 
Corporation) icon, indicating they are recyclable. To find a recycling center near 
you, ask your local hobby dealer or visit www.rbrc.org.

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 16 use or 

handle LiPo battery packs without the supervision of a knowledgeable and 
responsible adult. 

Your model is able to use LiPo batteries with nominal voltage not to exceed 11.1 
volts (3S packs). LiPo batteries have a minimum safe discharge voltage threshold 
that should not be exceeded. The Velineon VXL-3s electronic speed control is 
equipped with built-in Low-Voltage Detection that 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.

Low-Voltage Detection on the speed control is just one part of a comprehensive 
plan for safe LiPo battery use.

 

It is critical for you, the user, to follow all 

other instructions supplied by the battery manufacturer and the charger 
manufacturer for proper charging, use, and storage of LiPo batteries. Do not 
attempt to charge LiPo batteries with the Traxxas charger included in this 
package. Make sure you understand how to use your LiPo batteries. 

Be aware 

that Traxxas shall not be liable for any special, indirect, incidental, or consequential 
damages arising out of the installation and/or use of LiPo batteries in Traxxas 
models. 

If you have questions about LiPo battery usage, please consult with 

your local hobby dealer or contact the battery manufacturer. 

As a reminder, all 

batteries should be recycled at the end of their useful life.  

SPEED CONTROL

• Disconnect the Batteries: Always disconnect the battery pack from  

the speed control when not in use. 

• 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 heat sink can get extremely hot, so be careful not to touch 

it until it is cool. Supply adequate airflow for cooling.

• Use Stock Connectors: If you decide to change the battery or motor connectors, 

only change one battery or motor connector at a time. This will prevent damage 
from accidentally mis-wiring the speed control. Please note that modified speed 
controls can be subject to a rewiring fee when returned for service. Removing the 
battery connector on the speed control or using the same-gender connectors on 
the speed control will void the product’s warranty.

• Insulate the Wires: Always insulate exposed or damaged wiring with heat shrink 

tubing to prevent short circuits
