Make sure to read this Assembly Manual and Setup Guide in its entirety before starting assembly. This will allow you to become
familiar with the assembly process and ultimately make assembly quicker and easier.
l
When we refer to right and left sides, we are referring to the driver's point of view, as if you were sitting inside the X-Crawler ARR.
l
To prevent stripping the hex head screws, make sure to use a good-quality hex wrench of the correct size.
l
When installing the pinion gears onto the motors, make sure that you tighten the grub screws against the flat spots on the motor
output shafts. This will prevent the pinion gears from spinning during use. If the motors do not have a flat spot on their output shafts,
cut a flat spot into them using a small file or grinding disc.
l
Tighten all fasteners securely and apply threadlock to any screws that thread into metal. This will ensure that the screws do not loosen
from vibration during use.
l
When using threadlock, make sure to allow it to cure overnight before use. It's also important that both parts you apply threadlock to
are clean, dry and free of any grease or oil.
l
If you have difficulty sliding the antenna wire through the antenna support tube, first pull the antenna wire through your fingers several
times to straighten it, then lightly wet the antenna wire with glass cleaner. The glass cleaner will make the antenna wire slide through
the antenna support tube much easier.
l
When you're installing the tapered collets when joining the chassis assemblies, note the direction that the tapered collets are installed. The
narrow side of each tapered collet should be toward the inside of the ball links, otherwise the chassis will not articulate fully and will bind.
l
When installing your steering servos and motors, make sure to leave a little bit of slack in the wires so that when the suspension
articulates it won't pull, or otherwise damage, the wires.

antenna Mount:
Holds the antenna support tube
that your receiver antenna is fitted into.
body Mount:
Machined from aluminium for
strength, the body mount supports the body. The
X-Crawler ARR features four body mounts for
maximum support.
Chassis Side Plate:
Secures the suspension link
rods and the upper and lower chassis plates to form
the core of the chassis.
Gearbox/axle Carrier:
Made from high-strength,
machined aluminium, the X-Crawler ARR features
solid drive shafts and steel gears which are perfect
for rock crawling. The axle carriers are machined
from aluminium for strength and feature ball
bearings to support the drive shafts and axles.
Shock absorber:
Each shock is oil-filled and uses
a spring that is well suited for most rock climbing
conditions. The shocks feature threaded shock
bodies that allow the shocks to be easily tuned
for different conditions. The shocks come standard with # 200 (20 weight) oil and blue springs.
Steering link rod:
Connects the two steering knuckles together, either end. The steering link rod is adjustable so you can make toe-angle
adjustments to the front and rear wheels.
Steering tie-rod:
The tie-rod connects the steering linkage and the steering knuckles, either end. The tie-rods are adjustable so you
can make toe-angle adjustments to the front and rear wheels.
Suspension link rods:
Connects the centre chassis assembly to the outer chassis assemblies/gearboxes. The suspension link rods
allow the chassis to articulate almost 90 degrees.
wheel/tyre assembly:
The X-Crawler ARR features moulded rubber tyres with a tread pattern that is good for most rock crawling
courses. The wheels are machined aluminium bead lock type which are extrememly strong and make it easy to change tyres for
different course conditions.
