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 the included stand. Make sure your hands are
clear of the moving parts of the model. Keep fingers and objects
away from the propeller!
3. Plug the battery packs in the model into the speed control. This
turns the speed control on.
4. 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.
5. When looking down at the rear of model, the
rudder should be pointing straight back. If the
rudder is turned slightly to the left or right, turn
off TSM (see page 16) and slowly adjust the
steering trim control on the transmitter until it
is pointing straight back; then, return the Multi-
Function knob to the desired TSM setting.
6. 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.
7. Once your adjustments have been made, turn the receiver and
the model off by unplugging the batteries, then switch off the
transmitter. The transmitter is always switched off last.

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 watch the model. Make sure hands and clothing are
clear of the propeller 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. 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.
Remember, always turn the
TQi transmitter on first and
off last to avoid damage to
your model.
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 Fail-Safe activates
while you are operating
your model, determine the
reason for signal loss and
resolve the problem before
operating your model again.
Stop immediately at the first
sign of weak batteries. Never
turn the transmitter off when
the battery pack is plugged
in. The model could run out
of control.
