Using Reverse: While driving,
push the throttle trigger
forward to apply brakes.
Once stopped, return the
throttle trigger to neutral.
Push the throttle trigger
forward again to engage
proportional reverse.
Automatic Fail-Safe
The TQi transmitter and
receiver are equipped with
an automatic fail-safe system
that does not require user
programming. In the event of
signal loss or interference, the
throttle will return to neutral
and the steering will hold its
last commanded position. If
the fail-safe activates while
you are operating your model,
determine the reason for
signal loss and resolve the
problem before operating
your model again.
In order to re-acquire the
signal after the fail-safe has
activated, you will need
to walk a longer distance
closer to the model than the
distance the model travelled
out of range. Simply keep
walking towards the model
until you re-acquire the signal.
Multi-Function Knob
The Multi-Function knob can be programmed
to control a variety of functions. From the
factory, the Multi-Function knob controls
steering sensitivity, also known as exponential
or “expo.” When the knob is turned counterclockwise all the way to the
left (default position), expo is off and steering sensitivity will be linear
(the most commonly used setting). Turning the knob clockwise will
“add expo” and decrease the steering sensitivity in the initial range of
steering wheel travel left or right from center. For more detail on steering
exponential, refer to page 15.
USING THE RADIO SYSTEM
The TQi Radio System has been pre-adjusted at the factory. The
adjustment should be checked before running the model in case of
movement during shipping. Here’s how:
1. Turn the transmitter switch on. The status LED on the transmitter
should be solid green (not flashing).
2.
Elevate the model on a block or a stand so that all the tires are
off the ground.
Make sure your hands are clear of the moving
parts of the model.
3. Plug the battery packs in the model into the speed control.
4.
The on/off switch is integrated into the speed control. Press and
release the EZ-Set button on the speed control to turn the model
on. The LED will shine RED or GREEN (see note below). To turn the
EVX-2 off, press the EZ-Set button until the LED turns off.
Note
:
If the model is factory equipped with LiPo batteries, the LED will be
green, indicating that Low-Voltage Detection is activated. If the
model is factory equipped with NiMH batteries, the LED will be red,
indicating that Low-Voltage Detection is disabled.
Never use LiPo
batteries while Low-Voltage Detection is disabled.
See page 16 for
more on EVX-2 setup and operation.
5. Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak batteries.
6. When looking down at the model, the front wheels should be
pointing straight ahead. If the
wheels are turned slightly to the left
or right, slowly adjust the steering
trim control on the transmitter until
they are pointing straight ahead.
7. Gently operate the throttle trigger to ensure that you have
forward and reverse operation, and that the motor stops when
the throttle trigger is at neutral.
WARNING
:
Do not apply full
throttle in forward or reverse while the model is elevated.
8. Once adjustments are made, turn off the receiver on your model,
followed by the hand-held transmitter.
Range-Testing the Radio System
Before each running session with your model, you should range-test
your radio system to ensure that it operates properly.
1. Turn on the radio system and check its operation as described in
the previous section.
2. Have a friend hold the model. Make sure hands and clothing are
clear of the wheels and other moving parts on the model.
3. Walk away from the model with the transmitter until you reach
the farthest distance you plan to operate the model.
4. Operate the controls on the transmitter once again to be sure that
the model responds correctly.
5. Do not attempt to operate the model if there is any problem with
the radio system or any external interference with your radio
signal at your location.
Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will near the limit
of radio range. Use caution to keep your model in range. If you want
to see your model achieve its maximum speed, it is best to position
yourself in the middle of the truck’s running area, not the far end,
so you drive the truck towards and past your position. In addition to
maximizing the radio’s range, this technique will keep your model
closer to you, making it easier to see and control.
Your model’s radio system is designed to operate reliably up to the
approximate distance that it is no longer easy or comfortable to see
and control the model. Most drivers will struggle to see and drive
their model at distances farther than a football field (300+ feet). At
greater distances, you could lose sight of your model and you may
also exceed the radio system’s operating range, which will cause
the failsafe system to activate. For best visibility and control of your
model, keep your model within 200 feet, regardless of the maximum
range available.
No matter how fast or far you drive your model, always leave adequate
space between you, the model, and others. Never drive directly toward
yourself or others.
