All of us at Traxxas want you to safely enjoy your new Nitro 4-Tec. Operate 
your Nitro 4-Tec sensibly and with care, and it will be exciting, safe, and 
fun for you and those around you. Failure to operate your Nitro 4-Tec 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

•  Nitro 4-Tec is very fast! The Nitro 4-Tec is intended for experienced 

users with a high level of skill. The TRX 3.3 Racing Engine is extremely 
powerful and may require skilled driving to maintain control. Children 
under 16 years of age and inexperienced drivers should not operate the 
Nitro 4-Tec without the supervision of a responsible and knowledgeable 
(experienced) adult.

• 

Model engine fuel is dangerous and highly poisonous.

 Always follow all 

directions and precautions printed on the fuel container. Model engine 
fuel is poisonous to humans and animals. Drinking the fuel can cause 
blindness and death. Handle with care and respect.

•  Model engine fuel, especially when in a fuel dispensing bottle, may look 

like a cool drink to a child. 

Keep all fuel out of the reach of children at all 

times. Do not place fuel containers on the ground where children can 
reach them while you are driving.

•  Model engine fuel is flammable. Never allow smoking, sparks, heat or 

flame in the presence of fuel or fuel vapors.  

•  The engine, brakes, and exhaust system may become extremely hot 

during use. Be careful not to touch the parts, especially when refueling or 
stopping the engine.

•  Prolonged exposure to the engine exhaust can be harmful. Avoid 

breathing the engine exhaust. Always run your Nitro 4-Tec outdoors,  
in a well-ventilated area. Never run the engine indoors. 

•  Do not operate your Nitro 4-Tec at night, or anytime your line of sight to 

the model may be obstructed or impaired in any way.

•  Never operate your Nitro 4-Tec in crowds of people or busy pedestrian 

areas. Nitro 4-Tec is very fast  and could cause injury to those unaware 
of its presence. Keep small children at a safe distance away from the 
operating area.

•  Because Nitro 4-Tec is controlled by radio, it is subject to radio 

interference from many sources beyond your control. Since radio 
interference can cause momentary loss of control, always allow a safety 
margin in all directions around your model to prevent collisions. 

•  The engine can be loud. If the noise makes you uncomfortable, wear ear 

protection. Be considerate of your neighbors by not running your model 
early in the morning or late in the evening.

•  Do not kink the antenna wire. Kinks in the antenna wire will reduce range.
•  Do not cut the antenna “stinger” or any other part of the antenna wire. 

Cutting the antenna will reduce range.

•  Extend the antenna as far as possible for maximum range. Wrapping or 

coiling the antenna wire should be avoided. 

•  Do not allow the antenna wire to extend outside the body without the 

protection of an antenna tube, or the antenna wire may incur crash 
damage that could reduce range.

• 

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 packs properly. In 
addition to your battery and charger instructions, here are some more tips 
to keep in mind.
•  Use the supplied chargers to charge the included battery. See “Charging 

the EZ-Start Battery” on page 22. 

•  Never leave batteries to charge unattended.
•  Allow the battery pack to cool off 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.

•  Only use approved chargers for Nickel Metal Hydride (NiMH) battery 

packs (such as part #2921 or the EZ-Peak Plus charger, part #2933). Do not 
exceed the maximum charge rate of 1 amp.

•  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.

•  NiMH 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.call2recycle.org.
