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 pack in the model into the speed control.
4. The on/off switch is integrated into the speed control. With the
transmitter on, press and release the EZ-Set button (.25 seconds).
The LED will shine RED (see note, below). This turns the model
on. To turn the VXL-3s off, press and hold the EZ-Set button until
the LED turns off (.5 seconds). Note: If the LED shines green, Low-
Voltage Detection is activated. This will cause erratic performance
from the included NiMH battery pack. The default factory setting
is for Low-Voltage Detection to be disabled (LED shines red).
Make sure to turn the low voltage detection on when using LiPo
batteries. Never use LiPo batteries while Low-Voltage Detection
is turned off. See page 16 for more information.
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 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. 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 model's running
area, not the far end, so you drive the model 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
transmitter on. The transmitter's LED will flash red slowly.
2. Press and hold the receiver's LINK button as you switch on the
speed control by pressing the EZ-Set button.
