2. Have a friend watch the model.
Make sure hands and clothing are
clear of the propeller and other moving parts on the model.
3. Make sure your transmitter antenna is fully upright, 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 50mph, a model can cover 73 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 midpoint of the model’s running area,
not the far end, so you drive back and forth 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.
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
transmitter on. The transmitter’s LED will flash red slowly.
2. Press and hold the receiver’s LINK button as you plug in the speed
control.
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
rudder) corresponds
precisely with the steering
wheel. The ranges are
exaggerated
for illustrative purposes.
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
your model at high speeds, or anytime a less
aggressive steering feel is desired.
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.
The antenna is secured by a 3x4mm
set screw. To remove the antenna
tube, simply remove the set screw
with the included 1.5mm wrench.
When reinstalling the antenna, first
slide the antenna wire into bottom
of antenna tube until white tip of
antenna is at top of tube under the
black cap. Next insert the antenna
tube into the mount while making
sure that antenna wire is in slot in
the antenna mount, then install the
set screw next to the antenna tube.
Use the supplied 1.5mm wrench
to tighten the screw just until the
antenna tube is securely in place.
Do not over tighten.
Do not bend
or kink the antenna wire! Do not
shorten the antenna tube.
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.
