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!

Other Required Equipment 

To operate the Nitro Stampede, you will need these additional items. 
All of these items should be available from your hobby shop.  

1.

  8 AA batteries: 4 in the transmitter and 4 for the receiver

2.

 Small Phillips-head and flat-head screwdrivers (for adjustments)

3.

 After-run oil (to protect the engine from corrosion)

The TQ 2.4GHz Radio System 

Your Nitro Stampede Model 41094 is equipped with the Traxxas TQ 
2.4GHz transmitter. The transmitter has two channels: channel one 
operates the steering, and channel two operates the throttle. The 
receiver inside the model has three output channels. Your model is 
equipped with two servos and a receiver.

2.4GHz Spread Spectrum 

– This model is equipped with the 

latest R/C technology. Unlike AM and FM systems that require 
frequency crystals and are prone to frequency conflicts, the TQ 
2.4GHz system automatically selects and locks onto an open 
frequency, and offers superior resistance to interference and 
“glitching.”

Current

 – Current is a measure of power flow through the 

electronics, usually measured in amps. If you think of a wire as a 
garden hose, current is a measure of how much water is flowing 
through the hose.

Frequency band

 – The radio frequency used by the transmitter to 

send signals to your model. This model operates on the 2.4GHz 
direct-sequence spread spectrum.

mah 

– Abbreviation for milliamp hour, a measure of the capacity 

of the battery pack. The higher the number, the longer the 
battery will last between recharges.

Neutral position

 – The standing position that the servos seek 

when the transmitter controls are at the neutral setting.

NiCad

 – Abbreviation for nickel-cadmium. The original 

rechargeable hobby pack, NiCad batteries have very high 
current handling, high capacity, and can last up to 1000 
charging cycles. Good charging procedures are required to 
reduce the possibility of developing a “memory” effect and 
shortened run times.

NiMH 

– Abbreviation for nickel-metal hydride. Rechargeable 

NiMH batteries offer high-current handling and much greater 
resistance to the “memory” effect. NiMH batteries generally 
allow higher capacity than NiCad batteries. They can last up to 
500 charge cycles. A peak charger designed for NiMH batteries 
is required for optimal performance.

Receiver 

– The radio unit inside your model that receives signals 

from the transmitter and relays them to the servos.

Servo

 – Small motor units in your model that operate the steering 

and throttle mechanisms.

Transmitter 

– The hand-held radio unit that sends throttle and 

steering instructions to your model.

Trim 

– The fine-tuning adjustment of the neutral position of the 

servos, made by adjusting the steering trim knob on the face of 
the transmitter. 

2-channel radio system

 – The TQ 2.4GHz radio system, consisting 

of the receiver, the transmitter, and the servos. The system uses 
two channels: one to operate the throttle and one to operate 
the steering.
