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, batteries, 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 that were provided with the battery pack and your charger. It is your 
responsibility to charge and care for the battery backs 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 the 

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).
• 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. 

• Children should have responsible adult supervision when charging and 

handling batteries.

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. 

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.call2recycle.org.

SPEED CONTROL

• Disconnect the Battery: Always disconnect the battery 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 
connectors with no reverse-polarity protection 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.

• No Reverse Voltage: The speed control is not protected against reverse polarity 

voltage. When changing the battery and/or motor, be sure to install the same 
type of connectors to avoid reverse polarity damage to the speed control. 
Removing the battery connectors on the speed control or using the same-
gender connectors on the speed control will void the product’s warranty.

• No Schottky Diodes: External Schottky diodes are not compatible with reversing 

speed controls. Using a Schottky diode will damage the electronic speed 
control and void the 30-day warranty.
