Please make sure to read through the separate Brushless Speed Controller User Manual included to learn more about the ESC's
features and proper use. For throttle control range calibration and programming options, see pages 11 and 12.
Roll Cage:
The roll cage is constructed of aluminium and helps protect the components within the chassis. The roll cage also helps stiffen
the chassis because it's rigidly attached to the aluminium side frames, the rear shock tower and the front steering plate.
Shock Absorber:
Each shock is oil-filled and uses a spring that is well suited for most off-road conditions. The shocks are threaded
and feature preload tension rings that allow the shocks to be easily tuned for different driving conditions. The shocks come standard
with 30Wt oil and 1.6mm silver springs.
Shock Tower:
Secures the shock absorber while allowing many different geometry settings to suit different track conditions. The shock
towers are made from 4mm 6061 aluminium for strength.
Steering Servo:
Controls the 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.
Suspension Arm:
Helps support the Rail’s handling (when coupled to shock absorbers) and braking whilst ensuring maximum traction
(keeps the wheels in contact with the ground) and protects the chassis components from undue stress and strain.
Turnbuckle:
Joins the upper inner and upper outer suspension components. The turnbuckle is threaded, allowing you to adjust the
camber angle of the front and rear tyres.
Wheel/Tyre Assembly:
The Rail features moulded rubber tyres with a tread pattern that is good for most off-road applications. The
wheels are moulded in one piece from lightweight, high-impact plastic and feature a metal outer ring for extra strength.
Wing:
Provides downforce to ensure maximum traction. Wing angle can be adjusted to suit different track conditions.

Brushless Power System Overview
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).
The Accessory Fan Connector is used to connect the brushless motor heat-sink cooling fans. It is NOT recommended to use it to
power any other types of accessories.
The ESC battery leads feature male battery connectors on both the positive and the negative leads. This allows plug-and-play
compatibility with most hard-case Li-Po car battery packs and allows easy dual battery pack wiring with the use of one simple
jumper. For more information, see page 10.
In the default configuration the transmitter's throttle channel servo reversing function should be set to REV (Reverse) and the motor
leads should be connected as follows: (A) Blue to motor Black, (B) Yellow to motor Red, and (C) Orange to Motor Yellow.
The Set Button is used during throttle control range calibration. For more information, see page 11.
