CHaSSiS SetuP Guide
IMPORTANT:
It's very important when making changes to the settings of your X-Crawler ARR that you make the changes the
same for each side. For example, if you change the spring tension on the right front shocks, you should change the spring tension
on the left front shocks the same amount, etc.
Chassis alignment and geometry are important if you want your X-Crawler ARR to perform well. A good performing truck means a
truck that is easier to drive, too. Follow our guidelines in this section to get the most out of your X-Crawler ARR.
The guidlines that we provide in this section are a good starting point for most users, however, there are numerous different setting
combinations that will give you different results. You should experiment with all of these settings to find what works best for your particular
combination of course, driving style and truck performance.
rdS8000 radio Control SySteM SetuP
To get the most out of your X-Crawler ARR, we recommend using a twin-stick radio control system with high end mixing capabilities. For
those who use the recommended Airtronics/Sanwa RDS8000 radio control system, we've provided some recommendations to help you
get started. The RDS8000 transmitter settings below allow for 4 wheel or 2 wheel drive and offers 2 wheel or 4 wheel
steering. The transmitter is set up in MODE 1. If you have the transmitter mixing set up with 4 wheel drive, then it's automatically set up
for 4 wheel steering because it's on the same compensation mixing switch. There are a number of different ways to set up your
transmitter, so experimentation will be necessary to find out what works best for you.

We recommend removing the red wire from
one
ESC throttle
lead so that the BEC input into the receiver won't be too high,
as both ESCs are providing this to the receiver. Removing
the red wire as indicated will ensure the receiver won't have
too much voltage or amperage going to it.

l
For C-MIX, set MAS to 'EL' and TH to 'SLV'
l
E->T C-MIX is set to '100%', forward and reverse
l
For the second C-MIX, set MAS to 'AI' and set RU to 'SLV'
l
A->R C-MIX is set to '90%', left and right
Once the C-MIX is set, you can activate it using the 'AUX 1' switch. You'll notice that in small print it says 'C-MIX'. When the C-MIX is
activated, both motors and both servos will work together. This way you will have 4WD with the left stick and 4WS with the right stick.
You can still give independent controls of steering and throttle with the opposite sticks (i.e., even though you have mixing preset, you
can give independent input to the rear motor on the right stick or give rear steering on the left stick as those are merely slaved channels
and can operate independently until mixed). If you turn the mixing off, you have full control of each channel. This will allow you to dig
the front end and have it come around or you can allow the X-Crawler ARR to crab, etc.
With the mixing off it's possible to make the X-Crawler ARR go sideways by giving opposite motor input with the 4WS. When you want
to go back in the other direction, simply move the aileron and rudder sticks. It's possible to make the X-Crawler ARR spin on its own
axis and more, just by giving different inputs.
