WARNING!

Carefully read and follow all instructions in this and any accompanying 
materials to prevent serious damage to your model. Failure to follow 
these instructions will be considered abuse and/or neglect. 

Introduction 

Thank you for purchasing the Traxxas Nitro Stampede. This 
manual contains the instructions you will need to operate and 
maintain your Nitro Stampede. 

Look over the manual and examine 

the Nitro Stampede carefully before running it.

 If for some reason 

you think the Nitro Stampede is not what you wanted, then do not 
continue any further. 

Your hobby dealer absolutely cannot accept 

a Nitro Stampede for return or exchange after it has been run.

   

Please read 

all

 of the operating instructions and precautions 

before attempting to drive the Nitro Stampede. Even if you are 
an experienced R/C enthusiast, continue reading to learn about 
Nitro Stampede’s unique features. Pay special attention to the 
mechanical and safety precautions outlined in the manual.             
If you have any questions about your model, or its operation, call 
the Traxxas Technical Support Line toll-free at 1-888-TRAXXAS 
(1-888-872-9927); outside the U.S., call 972-265-8000. Technical 
support is available Monday through Friday, from 8:30am to 
9:00pm Central Standard Time. Technical assistance is also

of fun with your new Nitro Stampede.

Fuel 

It’s imperative that you use the correct fuel in your Pro.15 engine for 
maximum performance and engine life. Traxxas Top Fuel

®

 Power Plus

 

should be used to ensure correct engine lubrication, 
performance, and ease of tuning.

• Top Fuel is the only fuel that is 100% certified  

for use in Traxxas engines. 

• Traxxas Top Fuel is made with just the right balance 

of natural and synthetic lubricants to allow excellent 
throttle response and the best top-end performance, 
without sacrificing long-term durability. 

You may use 10% or 20% nitro-content fuel. Try to 
use the same percentage all the time. Avoid switching 
back and forth between fuels. We recommend that if you break in 
your engine on 20% fuel that you stick with that percentage. If you do 
move to a higher or lower percentage, make sure you readjust your 
fuel mixture to compensate.

Can other brands of fuel be used besides Top Fuel?

 There are 

other fuels that can provide satisfactory performance; however, 
there could be long-term costs in the form of decreased engine 
performance, loss of tuning ease, and shorter engine life. Only use 
fuels that contain both castor and synthetic oil.

Everyone has an opinion or a claim to make about fuel. The 
engineering team at Traxxas has spent years developing Traxxas 
engines. No one knows more about the specific fuel requirements of 
Traxxas engines than Traxxas engineers. We strongly urge you not to 
take chances with your engine investment and use the Traxxas fuel 
made for Traxxas engines. 

PERSONAL SAFETY PRECAUTIONS

  Every precaution outlined in this manual needs to be followed to help ensure safe 

operation. Operate your model sensibly and with care and it will be exciting, safe, 
and fun for you and your spectators. Failure to operate your model in a safe and 
responsible manner could result in property damage and serious injury. You alone 
must see to it that the instructions are followed and the precautions are adhered 
to. 

 

The Nitro Stampede is 

not intended for use by children without the supervision 

of a responsible adult.

 

Traxxas shall not be liable for any loss or damages, 

whether direct, indirect, special, incidental, or consequential, arising from the 
use, misuse, or abuse of this product and any chemical or accessory required to 
operate this product. 

•  Nitro Stampede is very fast! Children under 16 years of age and inexperienced 

drivers should not operate the Nitro Stampede 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 these 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 Stampede outdoors, in a well-ventilated 
area. Never run the engine indoors. 

•  Do not operate your Nitro Stampede at night or anytime your line of sight to the 

model may be obstructed or impaired in any way.

•  Never operate your Nitro Stampede in crowds of people or busy pedestrian 

areas. Nitro Stampede 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 Stampede 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.

•   You must extend the antenna wire 

in the model as far as possible for 
maximum range. In doing so, the 
antenna wire will be extended 
outside of the vehicle body. Do not 
wrap or coil the antenna wire to keep 
it from extending out of the body.

•   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 charger to charge the included battery. See “Charging the 

EZ-Start Battery” on page 6. 

•  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 NiMH battery packs (such as Part #2921 or 

the Traxxas EZ-Peak Plus, Part #2933). Do not exceed the maximum charge 
rate of 1amp.

•  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 (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.
