WARNING!

Carefully read and follow all instructions in this and any accompanying

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 new model, feel free to call 
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 
time. Technical assistance is also available through our website at 
Traxxas.com (e-mail us at [email protected]). We hope that 
you will enjoy many hours of fun with your new Nitro Stampede.

FUEL 

 
Fuel is the most critical component for making 
your engine perform properly. Improper fuels 
will cause hard starting, poor performance, 
and excessive wear on the engine. For the best 
performance from your TRX

®

 Pro.15 engine, use 

Traxxas Top Fuel.

®

 

 

Traxxas Top Fuel is the only 

model engine racing fuel which exceeds all of the 
Traxxas engine warranty requirements. It is specially 
formulated to resist heat, and is guaranteed to 
provide the best performance and longest life from 
your Traxxas engine. Top Fuel uses superior natural 
and synthetic lubricants in just the right amounts to 
deliver the crisp, clean throttle response and screaming top-end 
performance you want in a car fuel, without sacrificing long-term 
durability. Top Fuel’s consistency and reliability has been proven 
in thousands and thousands of engines so you can trust it in your 
engine with confidence. Traxxas cannot guarantee the quality and 
consistency of other manufacturers’ fuels. 

Some fuels are capable of destroying your TRX Pro.15 engine!

 If you  

must use a fuel other than Traxxas Top Fuel contact Traxxas first, at  
1-888-TRAXXAS, to find out if the fuel is safe for use with TRX engines.

FUEL BOTTLE 

Fuel is usually purchased by the gallon or quart, so 
a smaller bottle with a dispensing tube is required 
to fill the fuel tank. The fuel tank in the Nitro 
Stampede has a capacity of 75cc. The fuel bottle 
should always be capped to prevent the fuel 
from evaporating and becoming contaminated 
with debris or moisture. The alcohol and nitro 
contents of the fuel will evaporate, thus 
upsetting the fuel balance and spoiling the 
fuel. Do not use old or dirty fuel!

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 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 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.

•  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 5. 

•  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 TRX Power Charger, Part #3030X). 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.

•   Nickel Metal Hydride batteries must be recycled or disposed of properly.

(Part #5001)

Previous experience with radio controlled 
models is recommended. Models require 
a higher level of setup, maintenance, or 
support equipment.
