Decreased Steering Sensitivity (Negative Exponential)
By turning the
Multi-Function
knob clockwise, the
steering sensitivity
of the model will
be decreased. Note
that a relatively large
amount of steering
wheel travel results in
a smaller amount of servo travel. The farther
you turn the knob, the more pronounced
the effect becomes. Decreased steering sensitivity may be helpful
when driving on low-traction surfaces, when driving at high speed,
or on tracks that favor sweeping turns where gentle steering inputs
are required. The ranges are exaggerated for illustrative purposes.
Experiment! Try varying degrees of exponential. It’s easy to go back
to “zero” if you don’t like the effect. There’s no wrong way to adjust
exponential. Any setting that makes you more comfortable with your
model’s handling is the “right setting.”
SETTING UP THE ANTENNA
The receiver antenna has been set up and
installed from the factory.
When reinstalling the antenna, first slide
the antenna wire into the bottom of the
antenna tube until the white tip of the
antenna is at the top of the tube under
the black cap. Insert the base of the tube
into the antenna post. Take care not to
crimp the antenna wire. Slide the crimp
nut over the antenna tube and screw it
onto the antenna post. Use the supplied
tool to tighten the crimp nut on the post
just until the antenna tube is securely
in place. Do not overtighten or crush
the antenna wire against the chassis.
Do
not bend or kink the antenna wire! See
the sidebar for more information. Do not
shorten the antenna tube.
ADJUSTING THE ELECTRONIC
SPEED CONTROL
The MXL-6s speed control should not need reprogramming with
normal use; however, if you install a different radio system in your
model, or change the transmitter’s throttle-neutral setting from 50/50
to 70/30, you will need to reprogram the speed control. Follow these
instructions to reprogram the speed control:
1. Install the batteries of your choice in the battery compartments
and plug the batteries into the speed control.
2. Switch on your transmitter.
3. Hold full throttle while you switch on the MXL-6s controller. After a
few seconds, you will hear multiple tones and the RED LED will light.
4. Hold full brake. After a few seconds, you will hear multiple tones
and the YELLOW LED will light.
5. Release the trigger to the neutral position. After a few seconds,
you will hear multiple tones and ALL THE LEDs will light.
6. Wait a few more seconds for the speed control to ‘arm,’ indicated
by a double-tone. You are now ready to drive.
Disconnect Batteries After Use
Always disconnect the batteries from the speed control when
you are finished using your vehicle. The switch on the speed control
only shuts off power to the receiver and servos. The speed control
continues to draw power as long as it is plugged in and may over-
discharge your batteries if they are left connected to the speed
control.
