4) With the front wheels off the ground, operate the steering control
on the transmitter (channel 1). Check for rapid operation of the
steering servo and that the steering mechanism is not loose or
binding. If the servo operates slowly, check for weak batteries.
Turn the “steering trim” control on the transmitter to adjust the
servo so that the front wheels are pointing straight ahead. Check
to be sure that the wheels do not turn more in one direction than
in the other.
5) Operate the throttle trigger on the transmitter to ensure that
the throttle servo is operating properly. When the servo is in
the neutral position, the carburetor should be in its idle position
(you will adjust the engine idle speed later). When the throttle
trigger is pulled all of the way, the carburetor should be in the
fully open position. When the throttle lever is pushed forward,
the brake should be locked and the throttle should not close
any further than when at idle.
RANGE TEST THE RADIO
There are many things such as buildings, power lines, radio
transmitters, etc. which can adversely affect the performance of
your radio system. To make sure you do not have a “runaway”
model, range test the radio system. With the radio system on and
working, hold the truck and have a friend carry the transmitter
away from you the distance you plan to run the truck. Have the
friend operate the controls on the transmitter to be sure that
everything is working at full range.
PREPARING TO RUN
• INSTALLING THE EZ-START BATTERY
Use tie wraps to secure a
fully-charged
7.2 volt
battery back to the EZ-
Start control box. Plug
the battery connector
into the face of the
control box. The plug
will only go in one way.
STARTING THE ENGINE
STEP 1: INSTALL THE AIR FILTER
Remove the protective cap from the carburetor air intake. Install
the rubber air filter base and pre-lubed foam element onto the car-
buretor intake. The foam air filter element may be cleaned and
reused.
Always be sure the filter element is oiled properly
before running the engine.
For the best
filtration, use the type of oil made for foam
air filters. It should be available locally from
motorcycle shops and small engine repair
shops. Lightweight motor oil or after-run
oil may also be substituted. When the ele-
ment gets dirty, clean it with dish soap and
rinse. Next, saturate it with oil and then
squeeze out the excess oil. For extremely
dusty conditions, special two or three-
stage, pre-lubed filters are available from
Traxxas (Part #4062 and #4063).
STEP 2: FILL THE FUEL TANK
Use a small fuel bottle or bulb to put fuel into the tank. Only fill
the tank to the bottom of the fill neck. The Nitro Stampede can be
carefully refueled while the engine is running.
STEP 3: HIGH-SPEED MIXTURE SETTING
The high-speed mixture screw controls how much fuel enters
the engine during mid and high-speed operation. Turn the high-
speed mixture screw clockwise, by hand, until it stops
(Do not
tighten or the needle may be damaged).
Now, turn the mixture
screw counter-clockwise 2

Note: Your carburetor has been factory preset
for break-in. Do not read
just your carburetor
settings unless you suspect a problem.
The
following steps are for reference only.
NEVER TURN THE TRANSMITTER OR RECEIVER OFF
WHILE THE ENGINE IS RUNNING. THE MODEL COULD
RUN OUT OF CONTROL. (The on/off switch only turns
the receiver on and off. It does not turn off the engine.)
