This combination of power and cooling has solved the issue of thermal shutdowns to allow you to enjoy the Rail each and every run, whether using a simple 6 Cell Ni-MH battery pack, or a 4S Li-Po battery pack.

KIT CONTENTS After opening your Rail Brushless 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
ESC programming card. n Battery Requirements The Rail Brushless Off-Road Buggy can be powered using either one battery pack or two battery packs wired in series. You can use either Ni-Cd, Ni-MH, or Li-Po battery packs.
Page 6
ESC Battery Leads: The ESC battery leads are where you plug your battery pack in to power your Rail. The ESC battery leads feature high-quality 12 AWG silicone wire and gold-plated 4mm male Bullet connectors.
Page 7
For more information, see page 10. The motor used in the Rail is a sensorless brushless motor. Therefore, the Sensor input on the ESC is not utilised. The motor leads from the ESC can be plugged into any of the motor leads from the motor without issue. If the motor runs backwards, swap two of the motor leads and the motor will run in the correct direction (counter-clockwise).
Page 8
If you prefer to change the connectors, make sure to observe correct polarity and use heat-shrink tubing to insulate the solder joints. Before checking the steering and throttle controls, we recommend placing the Rail on a car stand so that the wheels are off the ground.
Page 9
PREPARING TO RUN YOUR RAIL bRUShLESS Off-ROAD bUGGY n Battery Pack Installation and Power Connections q Verify that the ESC On/Off switch is turned 'OFF'. To ensure your safety, it's important that the ESC be turned 'OFF' when connecting your battery pack(s).
Page 10
Checking the Steering and Throttle Controls IMPORTANT: Before checking the steering and throttle controls, we recommend placing the Rail on a car stand so that the wheels are off the ground. This will ensure your safety and the safety of your model while testing the throttle control.
Page 11
As a safety precaution to prevent damage to the drivetrain, the Rail must be stopped before going into reverse. When the Rail is moving forward and you push the throttle trigger to go into reverse, the Rail will begin to brake and come to a stop. To go into reverse, release the throttle trigger momentarily, then push the throttle trigger forward again.
Page 12
The ESC programming card can be powered by separate battery pack, or by the Rail's motor batteries for use at the track. In addition, all of the programming information is printed on the ESC programming card for the utmost in convenience.
Page 13
PREPARING TO RUN YOUR RAIL bRUShLESS Off-ROAD bUGGY Powering the ESC Programming Card from the Motor Battery, Continued..q Turn the ESC 'OFF'. The new settings will be saved in the ESC's memory. q Apply threadlock to the grub screw, then reinstall the pinion gear, making sure to tighten the grub screw against the flat spot on the motor shaft.
Page 14
The Rail features a 14T pinion gear that provides the highest top speed. If driving on a track or in smaller areas, we recommend using an XTM Racing 13T pinion gear. This will cut down slightly on the top speed, but acceleration will be better and you will get a little longer run-time.
Page 15
How you drive your Rail will dictate what settings you should be using. As an example, if you're driving your 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 Rail from bottoming out.
Page 16
Changing Shock Springs - Front and Rear Shock springs are easy to change and can make a difference in the way your Rail handles relative to the type of terrain you're driving on. If you drive your 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 Rail is very bumpy, you might consider using softer springs to help absorb the bumps.
Page 17
Adjusting Steering Sensitivity - Front You can adjust your Rail's steering sensitivity by tightening or loosening the servo saver spring. In general, tightening the servo saver spring will cause the steering to be more responsive, and loosening the servo saver spring will cause the steering to be less responsive.
Page 18
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 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 19
The gear mesh should be set so that there is very slight play between the pinion gear and the spur gear. If you're using either of the XTM Racing 12T, 13T, or 14T pinion gears, the gear mesh is set correctly based on the particular motor mounting holes you install the motor into.
