    KIT CONTENTS After opening your Nitro Rail Off-Road Buggy, remove all of the parts from the box and double-check that you have all of the items listed below. If you find a part is missing or damaged, please contact your regional distributor, using the Customer Service Information on page 3.
  • Page 5: Fuel Bottle

    Alkaline batteries. n Miscellaneous Tools and Other Items In addition to the products listed previously, the following tools and other items are recommended to run and maintain your Nitro Rail Off-Road Buggy.
  • Page 6 Engine: The Nitro Rail features a powerful .28 size two-stroke nitro engine with pull-starter for ease of use and great performance. Fuel Tank: The fuel tank holds the fuel that the engine uses. The fuel tank includes a fuel pressure nipple that connects to the tuned pipe to pressurise the fuel system and also features a quick-flip type lid for fast refueling.
  • Page 7 4mm 6061 aluminium for strength. Steering Servo: Controls the Nitro Rail's steering. A 'servo saver' is used to help prevent the servo gears from being stripped out. Steering Tie-Rod: The steering tie-rod connects the steering linkage and the castor block. The tie-rods are adjustable so you can make toe-angle adjustments to the front wheels.
  • Page 8: Tips From The Pros

    When you pinch the fuel line to stop the engine, you must pinch it hard and hold it. The engine will rev up quickly, then stop. We suggest holding the Nitro Rail while doing this, so that it doesn't lurch out of your hands. Take care to avoid moving and/or hot parts.
  • Page 9 When in the 'ON' position, the On/Off switch should be pushed backward. q Rotate the transmitter's steering wheel forward (to the right). The Nitro Rail's front wheels should turn right. IMPORTANT: If the wheels don't turn right, use the transmitter's steering channel servo reversing function to change the direction that the front wheels turn.
  • Page 10 [open about 1mm (1/16")] and the brake linkage should move forward and engage the brakes (i.e., the Nitro Rail will not be able to roll at all when pushed). q Let go of the throttle trigger and the brakes should disengage.
  • Page 11 Air Filter Upgrade Tip if Driving Your Nitro Rail in Sand If you'll be driving your Nitro Rail Off-Road Buggy in sand or in extremely dusty conditions, we suggest using a prefilter sleeve over the air filter to improve the air filter's performance. Wet the main air filter element, then slide the prefilter sleeve over the air filter.
  • Page 12 WITh ThE xTm RACING .28 NITRO ENGINE High Speed n Carburettor Familiarisation Needle Valve Low Speed Needle Valve Refer to the photo at left to familiarise yourself with your engine's carburettor. All of the carburettor settings come preset from the factory for initial starting and break-in, but you should have a small flat blade screwdriver handy to make adjustments to the carburettor during the break-in process.
  • Page 13 PRO TIP: We recommend that you place the chassis on a dedicated car stand or similar so that all four wheels are suspended off the ground. This will ensure that your Nitro Rail does not accidentally drive away when starting the engine if the idle setting is too high.
  • Page 14 IMPORTANT: When you pinch the fuel pick-up tube to stop the engine, you must pinch it hard and hold it. The engine will rev up quickly, then stop. We suggest holding the Nitro Rail firmly whilst doing this, so that it doesn't lurch out of your hands.
  • Page 15: Recommended Fuel

    Break-In on a Flat Surface Break in the engine by running the Nitro Rail on a flat surface (car park/parking lot, etc.) It's important that the engine not be placed under too much load and that it receive adequate airflow during the break-in process, so as not to overheat.
  • Page 16: Tuning The Engine

    Drive the Nitro Rail as you normally would for a while to get a feel for how the engine reacts to throttle. Now that you know the proper way to tune the engine, you can make slight adjustments to the carburettor until you are satisfied with the performance.
  • Page 17: Chassis Tuning Guide

    Nitro Rail. It's very important when making changes to the settings of your Nitro Rail that you make the settings the same for each side. For example, if you change the spring tension on the front right shock, you should change the spring tension on the front left shock the same amount, etc.
  • Page 18 'toe-out' is when the front of both tyres point away from each other. For the front tyres, toe-in will make the Nitro Rail track (run) straighter, but the steering will be more sensitive. Toe-out will desensitise the steering, making the Nitro Rail a little more driver-friendly.
  • Page 19 How you drive your Nitro Rail will dictate what settings you should be using. For example, if you're driving your Nitro Rail off-road and going over lots of jumps, you may want to increase the spring tension of the front shocks to help prevent the front of the Nitro Rail from bottoming out.
  • Page 20: Adjusting The Brake Linkage

    If you drive your Nitro Rail off-road, in a smooth, high-traction area, use stiffer springs to reduce body roll and weight shift. If the area where you drive your Nitro Rail is very bumpy, you might consider using softer springs to help absorb the bumps. If the area is bumpy and you use harder springs, the Nitro Rail will have a tendency to jump and hop around.
  • Page 21 Tyres The Nitro Rail features 1/8th scale buggy tyres that are sized to provide good overall performance with the 14T clutch bell installed. If you're racing your Nitro Rail, you may want to experiment with different diameter tyres, just the same as you would experiment with different clutch bells.
  • Page 22 Using a heavier weight oil will provide a more even amount of power to the front and rear. On loose tracks, this can cause the Nitro Rail to be too 'squirrely' (uncontrollable) or cause the rear end to slide out. For this reason, we only suggest using heavier oil if you're driving on a high-traction surface.
  • Page 23: Engine Maintenance

    General Maintenance Following a simple maintenance schedule will ensure that your Nitro Rail Off-Road Buggy operates in top condition every time you use it. It is strongly recommended. Check the chassis for any loose screws, especially the engine and the differential pinion output joint grub screws. Tighten them as necessary.
