thicker oils provide more damping. Use only 100% pure silicone
shock oil to prolong seal life. From the factory, shock oil is set to 30W
in the front and rear shocks.
The model’s ride height can be adjusted by adding or removing the
clip-on, spring preload spacers. Adjust the ride height so that the
suspension arms are slightly above being parallel to the ground.
Observe how the model handles in turns. Proper setup will add
stability and help prevent spin outs. Experiment with different
springs and shock oils to find what works best for your current track
conditions.
Centering Your Servo
If the trim controls on your transmitter seem off, you may need to
re-center your servo. Additionally, whenever your servo has been
removed for service or cleaning, it must be re-centered prior to
installation in the model.
1. Disconnect the servo horn from the steering servo.
2. Connect the steering servo to channel 1 on the receiver. Connect
the electronic speed control (ESC) to channel 2.
3. Place fresh “AA” batteries in the transmitter and turn the
transmitter power switch on.
4. Turn the steering trim adjustment on the transmitter to the center
“0” position.
5. Elevate the rear wheels of the model. Connect a fresh 7.2V battery
pack to the speed control and turn on the ESC (see page 11). The
servo will automatically jump to its center position.
6. Turn off the power to the model followed by the transmitter. The
servo horn is now ready to be installed.
7. Be careful not to move the servo shaft when installing the servo
horn. Readjust the ESC as described in the “Adjusting the Speed
Control” section.
Motors and Gearing
There are two different types of aftermarket motors that can be
purchased for your model, stock and modified. Stock motors all
have the same wire thickness and number of turns around the
armature as governed by sanctioned racing organizations. They
are inexpensive and widely available. Modified motors are more
expensive, may feature ball bearings, and come in a variety of wire
thicknesses and number of turns of wire on the armature. The fewer
number of turns of wire on the armature, the more powerful the
motor will be. Keep in mind that the more powerful the motor, the
less battery run time you will have.
One of the more significant advantages to your model’s
transmission is the extremely wide range of available gear ratios. It
can be geared low enough to run extremely hot, modified motors.
Modified motors should be geared lower (higher numerically) than
stock motors because they reach their maximum power at higher
RPM’s. A modified motor that is geared incorrectly can actually
be slower than a correctly-geared, stock motor. Use the following
formula to calculate the overall ratio for combinations not listed on
the gear chart:
If you are worried that you might be over-geared, check the
temperature of the battery pack and motor. If the battery is
extremely hot, and/or the motor is too hot to touch, your model is
probably over-geared. If you are not able to run your model for at
least four minutes before the battery dies, then change to a lower
gear ratio. This temperature test assumes that the model is close to
factory stock weight and operates freely with no excessive friction,
dragging, or binding, and the battery is fully charged and in good
condition.
The model is equipped with a Titan 12T motor. The gear
combination that comes stock on each model provides good overall
acceleration and top speed. If you want more top speed and less
acceleration, install the optional high-speed gearing (more teeth;
sold separately). The optional high-speed gearing is intended for
high-speed running on hard surfaces, and is not recommended for
off-road or repetitive starting and stopping.
The Titan 12T is equipped with an integrated cooling fan that is
effective during medium to high-speed operation. The gearbox is
specially vented to cool the motor. Repetitive starting and stopping
over short distances creates excess heat and will not allow the fan
to cool the motor properly. For this type of driving, smaller pinion
gears are recommended to reduce load on the motor.

Gearing Compatibility Chart:
The chart below shows a full range of
gear combinations acceptable for this
model. This does NOT imply that these
gear combinations should be used.
Over-gearing (bigger pinions, smaller
spurs) can overheat and damage the
motor and/or speed control.
