It's very important when making changes to the settings of your X-Terminator 2e that you make the settings the same for each
side. For example, if you change the spring tension on the front right shock, you should change the spring tension on the front
left shock the same amount, etc.
ChASSIS TUNING GUIDE
Chassis alignment and geometry are important if you want your X-Terminator 2e to perform well. A good performing buggy means
a buggy that is easier to drive, too! Follow our guidelines in this section to get the most out of your X-Terminator 2e.
Do not make any changes that are more than 3 degrees from the initial settings or the handling characteristics of your
X-Terminator 2e will become very poor.
The toe angle is the angle of both front tyres (or rear tyres) to each other, when viewed from above. 'Toe-in' is when the front of both
tyres point toward each other and 'toe-out' is when the front of both tyres point away from each other.
l
For the front tyres, toe-in will make the X-Terminator 2e track (run) straighter, but the steering will be more sensitive. Toe-out will
desensitise the steering, making the X-Terminator 2e a little more driver-friendly.
l
For the rear tyres, if you're running on a smooth surface, we suggest no toe-in. If you're running on a rough surface, we suggest about
1 ~ 2 degrees of toe-in. This will give the rear end a little more 'bite' (traction).
n
Adjusting Toe Angle - Front and Rear
Adding more than 3 degrees of toe-in or toe-out on the front will result in excessive loss of speed and erratic handling. Toe
adjustments should be measured with the X-Terminator 2e at its normal ride height.
l
0 degrees toe-in on the front and 2 degrees toe-in on the rear for overall best 4WD driveability on most surfaces. 2 degrees toe-in
on the rear is stock.
q To adjust the toe-in on the rear tyres, use one of the different suspension holders provided to set the desired toe angle, as described in the
procedures below. For convenience, the degree of toe angle is moulded into the back of each suspension holder.
q Remove the two 4 x 15mm Flat Head screws from the bottom of the chassis that
hold the rear suspension holder support in place, then remove the suspension holder
support from the chassis.
q Remove the two 4 x 12mm Button Head screws that hold the suspension holder in place,
then carefully pull out the suspension holder, being careful not to pull out the hinge pins.
q Install the desired suspension holder. Installation is the reverse of the disassembly
procedure.
PRO TIP: For more precise toe angle adjustments, use a dedicated toe angle
adjustment gauge, available at most hobby retailers.
q To adjust the toe-angle of the front tyres, turn the tie-rods in or out using an adjustable
wrench.

The X-Terminator 2e features a 13T pinion gear that will work well on a decent size track. If you're racing your X-Terminator 2e, you will
probably want to experiment with different pinion gears. In general, using a smaller pinion gear (12T) will result in quicker acceleration,
but slower top speed, and using a larger pinion gear (14T) will result in faster top speed, but slower acceleration. It's all a matter of
experimenting with different pinion gears to nd the one that best suits your track and driving style.
n
Adjusting Gearing
12T and 14T pinion gears are available as optional parts. For more information, see the Option Parts List beginning on page 54.
In addition, most aftermarket 1/8th scale pinion gears designed for brushless motors with a 5mm shaft should work. After installing
a different pinion gear, you may need to readjust the gear mesh. For more information, see page 19.
