This model is not intended 
for use by children under 
14 years of age without the 
supervision of a responsible 
and knowledgeable adult.

All instructions and 
precautions outlined in this 
manual should be strictly 
followed to ensure safe 
operation of your model.

SAFETY PRECAUTIONS

No previous experience with radio 
controlled models is required. 
Models require a minimum of setup, 
maintenance, or support equipment. 

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 that were provided with the battery 
packs 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 10. 

  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.

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.

  Using Two Batteries: When using two batteries the batteries must be 

connected in parallel. Never connect two batteries in series, this will 
cause the ESC to fail. See page 11 for more information.
