Thank you for purchasing the DuraTrax Nitro Evader ST.
This manual contains the instructions you need to build,
operate and maintain your new nitro R/C stadium truck.
Read over this manual thoroughly before building or
operating the Nitro Evader ST.

When the safety precautions are followed, the Nitro Evader
ST will provide years of enjoyment. Use care and good
sense at all times when operating this radio controlled
stadium truck. Failure to use this vehicle in a safe, sensible
manner can result in injury or damage to proper ty.You and
you alone must insure that the instructions are carefully
followed and all safety precautions are obeyed.

• Do not operate the Nitro Evader ST near people.
Spectators should be behind the driver or at a safe
distance away from the vehicle.

• Water can cause the electronics to short out and can
cause permanent damage.

• Alwa ys turn on the transmitter before turning on the receiver.

• Before turning on your radio, check to make sure that no
one else is running on the same frequency as your Nitro
Evader ST.

• The engine and exhaust produce quite a bit of noise. If
you are disturbed by the amount of noise this truck
produces, wear ear protection such as earplugs. Do not
run this vehicle when or where it can disturb others.

• The engine and exhaust can become very hot. Avoid
touching any of these parts during use and until they
have cooled down.

• Model engine fuel is poisonous. Make sure you read and
follow all of the precautions on the fuel container. Keep
fuel out of the reach of children.

• Model engine fuel is flammable and when ignited has a
flame that is difficult to see. Avoid sparks, flames,
smoking, or any other ignition source when fuel is near.

• The engine emits carbon dioxide just like real cars. Do
not operate this model indoors.

• Fully extend the transmitter antenna before operating
your vehicle.

• Avoid working over a deep pile carpet. If you drop a small
part or screw, it will be difficult to find.

• Place a mat or towel o ver y our work surface.This will prevent
parts from rolling off and will protect the work surface.

• Avoid running the truck in cold weather. The plastic and
metal parts can become brittle at low temperatures. In
addition, grease and oil become thick, causing
premature wear and poor performance.

• Test fit all parts before attaching them permanently.

❏ 1. Install the transmitter antenna by screwing it into the hole on

the top of the transmitter.Give the antenna a mild tug to make sure
that it is properly secured in the transmitter.

❏ 2. Slide open the battery door on

the bottom of the transmitter. Install
eight (8) “AA” batteries

into the
transmitter in the configuration
molded into the plastic on the battery
holder. Reinstall the battery door.
Warning: Always extend the
transmitter antenna before operating
your vehicle.

❏ 3.T urn on the transmitter using the s witch on the side.The red light
on the side of the transmitter should light up. If there is no light on,
turn the transmitter off and check to ensure that the batteries are
making contact with the metal contacts in the battery holder. Make
sure the batteries are installed correctly.Turn the transmitter on and
check for the red light.If the red light appears, turn off the transmitter.
If the red light blinks, the batteries are low and should be replaced.

❏ 4. Remove the twist-tie from the receiver antenna wire. Locate
the antenna tube, and thread the receiver antenna through the
antenna tube. The antenna wire will be longer than the antenna
tube. DO NOT CUT OR COIL THE ANTENNA WIRE. Press fit the
antenna tube into the hole in the top of the receiver box.Tip: Run

the antenna wire through your fingers to straighten out the
kinks before

running through the antenna tube. Also, applying

a

small amount of soap and water to the antenna wire will help

lubricate the wire for threading into the antenna tube.

❏ 5. Remove the (2) 3x8mm pan head self tapping screws (L) from
the receiver battery box (65).Remove the receiver battery box lid

(66).

❏ 6. Remove the 4 cell receiver battery box from the radio box and
install (4) “AA” included batteries into the batter y holder. Follow the
configuration molded into the battery holder. Reinstall the receiver
battery holder back into the radio box. Plug the connector on the
receiver battery into the socket on the receiver switch wire. The
receiver battery connector can only be plugged in one way.Tuck the
wires into the groove in the radio bo x so that the y do not get crimped
under the radio box lid. Re-install the radio box lid and secure it in
place with the (2) 3x8 pan head self tapping screws.

❏ 7.Turn the transmitter and receiver on and chec k that the servos
are properly centered. Move the throttle and steering back and
forth to check that they are functioning properly.

❏ 8. Decal the body if desired.
❏ 9. Thoroughly soak the air filter element with the included air

filter oil. Work the air filter oil into the entire air filter element, then
using a clean, dry paper towel squeeze the excess air filter oil out
of the air filter element. Note: When the air filter element

becomes dirty, remove the air filter element from the Nitro
Evader and gently wash it out with warm water and dish soap.
After the air filter element is completely dry ,you can re-oil and
re-install it onto your Nitro Evader.

❏ 10.Switch off the receiver, then the transmitter.

❏ 1. Remove the Nitro Evader ST and the parts bag from the box.

❏ 2. Locate and remove from the Parts Bag 2: steering servo

mounts (6), one servo arm (8) (determine which servo arm is
required for your radio system), one ball stud (81), one f oam washer
(67), two 3x8 pan head screws (L) and two 3x8 flat head machined
screws (A).

❏ 3. Attach the servo mounts (6) to the servo using the two (2)
3x8mm screws (L) as shown.

❏ 4. Install the ball stud (81) into the flat side of the steering servo
arm (8) in the upper hole. With the steering servo centered as
described in “Preparing the Radio System,” install the correct
steering servo arm onto the servo splines as sho wn abov e, making
sure that the servo arm is as close to vertical as possible. Note: If
the steering servo is not properly centered, the steering could be
off. Center the servo and then reinstall the servo horn screw,
securing the horn onto the servo.

❏ 5. Remove the (3) 3x10mm (I) and (2) 3x15mm screws (H) from
the top of the upper brace (52). Remove (2) 3x8mm flat head
machine screws (A) that hold the upper brace to the main chassis
(1). Remove the upper brace from the main chassis.

❏ 6. Install the steering ser vo into the mounting slot. Line up the
holes in the servo mounts with the two holes in the chassis. Note:
There are two different mounting holes in the servo mounts. Use
the appropriate holes for your servo. Install the two (2) 3x8 flat
head machined screws (A) through the bottom of the chassis into
the servo mounts.

❏ 7. Attach the steering link ball cup (5) onto the ball stud (81) on
the servo.Note: Do not reinstall the upper brace (52) back onto the
chassis (1) until later.

❏ 1.Remove the (2) 3x8mm pan head self-tapping scre ws (L) from
the receiver battery box (65). Remove the receiver batter box lid
(66). Note: (4) Four “AA”batteries should already be installed

the receiver battery box. Install the receiver battery box into the

receiver battery holder.Tuck the wires into the groove in the radio
box so that they do not get crimped under the radio box lid.
Re-install the radio box lid and secure it in place with the (2)
3x8mm pan head self-tapping screws.

❏ 2. Route the receiver battery box wire through the shock tower
and across the top of the transmission. Tuck the receiver battery
box wire into the wire holder molded into the top of the
transmission case. Route the wire under the bottom of the engine
and along the side of the fuel tank. Note: Make sure the receiver

battery box wire is routed so that it cannot get caught in any
moving parts, like the engine’s flywheel. Secure the receiver

battery box wire to the fuel tank using a small tie-straps and the
molded tabs on the side of the fuel tank.

❏ 1. Remove the receiver box cover (69) from the radio plate (68)
by removing the (2) 3x8mm pan head self tapping screws (I).

bottom of the chassis.

❏ 3. Place the throttle servo into the radio plate as shown. Route
the servo wire through the hole in the receiver box. Note the
location of the servo output shaft. Secure the ser vo to the radio
plate using four 3x8mm screws (L).
