- Use the same techniques as you did in step 3 above to connect the second outer
link rod from the centre chassis assembly to the outer link rod mount on the outer
chassis assembly (see image at left).
3
- Connect one outer link rod from the centre chassis assembly to the outer link rod
mount on the same outer chassis assembly, using one M3 x 22mm cap screw, two
M3 tapered collets and one M3 lock nut.
PRO TIP:
Use an adjustable wrench to hold the lock nut in place while you tighten
the lock nut.
IMPORTANT:
Again, 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.
5
- Repeat procedures 2~4 to install the second outer chassis assembly to the the centre
chassis assembly.
IMPORTANT:
Install the two centre link rods to the middle hole in the outer chassis
link rod mount and make sure that the narrow side of each tapered collet is toward the
inside of the ball links, otherwise the chassis will not articulate fully and will bind.
Final aSSeMbly
The X-Crawler ARR comes from the factory partially assembled. Final Assembly should not take too long. Here is the list of procedures
that must be done to finish your X-Crawler ARR:
l
Join the two outer chassis assemblies to the centre chassis assembly, then install the body mounts.
l
Install your electronics - servos, motors, electronic speed controllers (ESCs), and battery pack.
l
Prepare and paint the body shell in the colour(s) of your choice, then apply the decals.
l
Fit the body shell and set up the chassis to your desired specifications.

- Remove the wheels from both outer chassis assemblies. Set the wheels and the wheel nuts aside for now.
IMPORTANT:
Removing the wheels will make it easier to join the chassis assemblies and to install the steering servos and motors.
IMPORTANT:
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.
2
- Connect the two centre link rods from one end of the centre chassis assembly to the
middle hole (a)
in one outer chassis assembly link rod mount, using one M3 x 40mm
cap screw, four M3 tapered collets and one M3 lock nut.
PRO TIP:
Thread the wheel nuts back onto the axles to prevent the hex hubs from falling off during assembly.
IMPORTANT:
Both ends of the centre chassis assembly are the same and both outer chassis assemblies are the same. There is
no front or rear. The gearbox cases on the outer chassis assemblies should point toward the centre of the chassis (see below).
