6. Operate the throttle trigger on the transmitter and check for
rapid operation of the throttle servo. When the throttle trigger
is pulled back, the carburetor should open. When the throttle
trigger is pushed all the way forward, the brake should lock.
7. 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 with the engine off.
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. At 60mph, a model can cover 88 feet every
second! It’s a thrill, but 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.
No matter how fast you drive your model, always leave
adequate space between you, the model, and others. Never
drive directly toward yourself or others.
TQi Binding Instructions
For proper operation, the transmitter and receiver must be
electronically ‘bound.’
This has been done for you at the factory.
Should you ever need to re-bind the system or bind to an additional
transmitter or receiver, follow these instructions.
Note
: You will
need to open the receiver box to access the receiver. The receiver
must be connected to a 4.8-6.0v (nominal) power source for binding
and the transmitter and receiver must be within 5 feet of each other.
1. Press and hold the transmitter’s SET button as you switch
transmitter on. The transmitter’s LED will flash red slowly.
Release the SET button.
2. Press and hold the receiver’s LINK button as you switch on
the model on. Release the LINK button.
3. When the transmitter and receiver’s LEDs turn solid green, the
system is bound and ready for use. Confirm that the steering and
throttle operate properly before driving your model.
Steering Sensitivity (Exponential)
The Multi-Function knob on the TQi transmitter has been
programmed to control Steering Sensitivity (also known as
exponential). The standard setting for Steering Sensitivity is
“normal (zero exponential),” with the dial full left in its range of
travel. This setting provides linear servo response; the steering
servo’s movement will correspond exactly with the input from the
transmitter’s steering wheel. Turning the knob clockwise from center
will result in “negative exponential” and decrease steering sensitivity
by making the servo less responsive near neutral, with increasing
sensitivity as the servo nears the limits of its travel range. The farther
you turn the knob, the more pronounced the change in steering
servo movement will be. The term “exponential” comes from this
effect; the servo’s travel changes exponentially relative to the input
from the steering wheel. The exponential effect is indicated as a
percentage—the greater the percentage, the greater the effect. The
illustrations below show how this works.
Normal Steering Sensitivity (0% exponential)
In this illustration, the steering servo’s travel (and with it,
the steering motion of the model’s front wheels) corresponds
precisely with the steering wheel. The ranges are exaggerated for
illustrative purposes.
When the engine is running,
do not use throttle trim
from the transmitter to
adjust the engine idle speed.
Always use the idle speed
adjustment screw (see page
17) on the carburetor.
