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. Make sure your transmitter antenna is straight up, and then 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 or far 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: 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 the
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 speed
control by pressing the EZ-Set button. 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 the left 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.
To prevent loss of radio range
do not kink or cut the black wire,
do not bend or cut the metal tip,
and do not bend or cut the white
wire at the end of the metal tip.
