Thank you for purchasing the DuraTrax Nitro Demon. 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 Demon.

When the safety precautions are followed, the Nitro Demon 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 property. You and you alone must insure that the instructions are carefully followed and all safety precautions are obeyed.

• Do not operate the Nitro Demon near people.

Spectators should be behind the driver or at a safe distance away from the vehicle.

• The engine and exhaust produces 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.

• Before turning on the transmitter, make sure that no one else is on your frequency.

• 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 over your 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.

We have engineered the Nitro Demon to take the rough and tumble abuse that makes R/C stadium trucks fun. We are so confident of the quality and durability of the Stress-Tech

™

plastic parts that we will replace any Stress-Tech plastic part you break during the first 6 months you own the truck. Just send in the part to us and we will send you a Free replacement. Please see the Nitro Demon parts list for the items covered under the Stress-Tech guarantee.

To receive your free replacement part please send the following to the Hobby Services address listed on the cover of this manual:

• The broken part must be included.

• The part number and description of the broken part.

INTRODUCTION

TABLE OF CONTENTS

Repair service is available anytime.

• After the 90 day warranty, you can still have your Nitro Demon repaired for a small charge by the experts at DuraTrax’s authorized repair facility, Hobby Services, at the address listed on the front page of this manual.

To speed up the repair process, please follow the instructions listed below.

1. Under most circumstances return the ENTIRE system: truck

and radio. The exception would be sending in a Stress-Tech part. See the instructions under Stress-Tech Guarantee.

2. Make sure the transmitter is turned off, all batteries are

removed and fuel is drained from the tank.

3. Send written instructions which include: a list of all items

returned, a THOROUGH explanation of the problem, the service needed and your phone number during the day. If you expect the repair to be covered under warranty, be sure to include a proof of date of purchase (your store receipt or purchase invoice).

4. Also be sure to include your full return address.

All pictures, descriptions and specifications found in this instruction manual are subject to change without notice. DuraTrax maintains no responsibility for inadvertent errors in this manual.

Do not use too much force when tightening self-tapping screws into plastic. Overtightening will cause the threads in the plastic to strip. We recommend that you stop turning a self-tapping screw when you feel some resistance as the head of the screw comes in contact with the plastic. Avoid using powered screwdrivers when assembling this kit. They tend to overtighten the screws. Do not use thread locking compound on any self-tapping screws. The thread locking compound may damage the plastic. IMPORTANT: Use thread lock on any fastener that is threaded into metal or fastened with a nut. Vibration from the engine will cause the screws to loosen if thread locking compound is not used.

To operate the Nitro Demon RTR these items are required:

• Fuel (DuraTrax Red Alert fuel - DTXP0520)

• Air Filter Oil (DTXC2465)

• Glow plug wrench (DTXR1170)

• Hobby knife (HCAR0105), #11 blades (HCAR0211)

❏ 1. Remove the Nitro Demon, transmitter and parts

from the box.

❏ 2. Remove the twist-tie from the receiver antenna

wire. The receiver antenna wire is a bundled thin wire that is attached to the receiver. Run the length of the antenna wire through your fingers to help straighten the wire out, this will make it easier to insert the wire through the tube. Remove the antenna tube from the decal bag. Slide the receiver antenna wire through the antenna tube. Do not coil or cut the antenna. Cut two pieces of fuel tubing 1/8" wide and slide them over the outside of the antenna tube and wire. This is to help hold the antenna wire on and avoid getting the antenna wire cut in a roll over. Note the placement of the tubing on the antenna tube.

❏ 3. Remove the air filter parts from the parts pack.

Slide the large rubber O-ring around the threads of the outer housing. The O-ring will help seal the air filter housing together. Soak the air cleaner element with an air filter oil, light machine oil, or, in a pinch, shock oil. Thoroughly soak the foam element and squeeze out the excess. Then install the filter element into the plastic outer housing.

❏ 4. Press the “L” shaped boot onto the bottom housing

of the air filter. Using one of the included tie-straps, tightly secure the boot onto the bottom housing. Cut off the excess portion of the tie-strap. Screw the bottom and outer filter housing together. Note: Overtightening

will strip the threads.

❏ 5. Place the air filter onto the carburetor. Using the

remaining included tie-strap, tightly secure the air filter to the carburetor. Cut the excess portion of the tiestrap off to avoid interference.

❏ 6. Remove the receiver battery holder from the radio

box. Install (4) “AA” batteries (included) into the battery holder in the configuration molded into the battery holder.

❏ 7. Cut a piece of foam the size of the radio box and

place it in the bottom for all of the equipment to set on. Re-install the receiver battery into the radio box. Note the placement of the receiver battery in the box. Make sure that the receiver switch is in the “off” position. Plug the connector on the receiver battery into the socket on the receiver switch. Wrap the receiver with the included foam rubber (if desired, secure with a rubber band, not included) to help reduce possible radio interference from vibration.

❏ 8. Remove the transmitter antenna from the holder

and screw it into the hole on the top of the transmitter.

❏ 9.Slide open the battery door on the bottom of the

transmitter. Place 8 “AA” batteries into the holder in the configuration molded into the plastic on the battery holder. Re-install the battery door.

❏ 10. Turn on the transmitter using the switch on the

side (see photo step 9). 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.

❏ 11. Remove the lower screw from each of the body

posts so that the posts can be placed upright. Reinstall the screw through the shock tower into the body post as shown.

❏ 12. Remove the plastic from the outside of the body.

Apply the decals to the body if desired.

❏ 13. Remove the body clips from the parts bag.

Insert a body clip through bottom hole on each body mount post. Place the body onto the body mounts and secure with body clips. You may choose to trim the body mounts shorter.

You are ready to go! Watch the video one more time and turn to page 14 to learn about tuning the engine, performance and maintenance tips.
