Tank 1

1.  Drive the model with the 

body off.

2.  Driving procedure: 

Gently pull the throttle trigger to 1/4 throttle 

over a 2-second count. Then gently apply the brake to stop

Count the two seconds out while accelerating: one thousand one, 
one thousand two, and then stop. Operate the throttle trigger as 
smoothly as you can. 

Repeat this starting and stopping procedure 

until the first tank of fuel is nearly empty.

3.  Look for thick blue smoke exiting the exhaust outlet. If there is  

no smoke, richen the high-speed needle 1/4 turn, by turning the 
needle counterclockwise.

4. When the fuel tank is nearly empty, shut off the engine by pinching 

the fuel line connected to the carburetor.

5.  Let the engine cool for 15 minutes.
Note: If at any point the engine cuts out or stalls during gentle 
acceleration, richen the high-speed needle 1/4 turn by turning the 
needle counterclockwise.

Tank 2

1.  From tank 2 forward, the model should be driven 

with the body on.

2.  Driving procedure: 

Gently pull the throttle trigger to 1/2 throttle 

over a 2-second count. Then gently apply the brake to stop. 

Count 

the two seconds out while accelerating: one thousand one, one 
thousand two, and then stop. 

Repeat this starting and stopping 

procedure until the second tank of fuel is nearly empty.

3.  When the fuel tank is nearly empty, shut off the engine and let it 

cool for 15 minutes.

Tank 3

1.  Driving procedure: 

Gently pull the throttle trigger to 1/2 throttle 

over a 3-second count. Then gently apply the brake to stop.

 Count 

the three seconds out while accelerating: one thousand one, one 
thousand two, one thousand three, and then stop. 

Repeat this 

starting and stopping procedure until the third tank of fuel is 
nearly empty.

2.  As the engine loosens, the idle speed may increase and cause  

the model to try to creep forward when stopped. Reduce the  
idle speed by turning the idle adjustment (see page 15) on the 
carburetor counterclockwise. 

3.  When the fuel tank is nearly empty, shut off the engine and refuel. 

From here on, you do not need to let the engine cool between tanks.

Tank 4

1. Driving procedure: 

Gently pull the throttle trigger to full throttle 

over a 3-second count. Then gently apply the brake to stop.

 Count 

the three seconds out while accelerating: one thousand one, one 
thousand two, one thousand three, and then stop. 

Repeat this 

starting and stopping procedure until the fourth tank of fuel is 
nearly empty. 

2.  Apply the throttle gradually! Your finger should not reach full 

throttle until the end of the three-second count. 

3.  Keep your driving smooth and consistent.
4.  When the fuel tank is nearly empty, shut off the engine and refuel. 

Tank 5

1.  Driving procedure: 

Gently pull the throttle trigger to full throttle 

over a 3-second count, hold for 2 more seconds, and then 
gently apply the brake to stop.

 Count the five seconds out while 

accelerating. 

Repeat this starting and stopping procedure until 

the fifth tank of fuel is nearly empty.

2.

 

When the fuel tank is nearly empty, shut off the engine and refuel.

Tank 6
STOP!

 

Clean your air filter before you proceed. 

Refer to the 

instructions on page 19. During the sixth tank of fuel, the engine can be 
tuned for general performance use. Proceed to the next section in this 
manual.

High Altitude Operation:
If you live in a high  
altitude region (5000 or more 
feet above sea level), the 
lower air density may require 
you to lean your high-speed 
fuel mixture slightly from the 
factory break-in settings. Try 
this if you are experiencing 
difficult starting or extremely 
sluggish engine performance 
at high altitude.

As you gain experience in 
the hobby, you may discover 
that many people have 
differing opinions on what 
is the proper procedure to 
break in a model engine. 

Only use the Traxxas break-in 
procedure. Other break-in 
procedures could result in a 
weak, damaged, or otherwise 
poor performing engine. 

The procedure outlined 
here was extensively tested 
and proven to yield better 
performing engines than 
other “common” break-in 
methods. Even if you have 
years of experience using 
model engines, please do not 
ignore this caution!
