RADIO SYSTEM
RADIO SYSTEM RULES
•
Always turn your TQi transmitter on first and off last. This
procedure will help to prevent your model from receiving
stray signals from another transmitter, or other source, and running out
of control. Your model has electronic fail-safes to prevent this type of
malfunction, but the first, best defense against a runaway model is to
always turn the transmitter on first, and off last.
• In order for the transmitter and receiver to bind to one another, the receiver in
the model must be turned on within 20 seconds of turning on the transmitter.
The transmitter LED will flash fast red indicating a failure to link. If you miss it,
simply turn off the transmitter and start over.
• Always have the transmitter and receiver turned on before you start the
engine. Never turn the radio system off while the engine is running. The
on/off switch in the model only turns the receiver on and off. It does not
turn off the engine.
• Always use new or freshly charged batteries for the radio system.
Weak batteries will limit the radio signal between the receiver and the
transmitter.
Loss of the radio signal can cause you to lose control of
your model.
RADIO SYSTEM BASIC ADJUSTMENTS
Throttle Neutral Adjustment
The throttle neutral adjustment is located
on the transmitter face and controls the
forward/reverse travel of the throttle trigger.
Change the adjustment by pressing the
button and sliding it to the desired position.
There are two settings available:
50/50: Allows equal travel for both acceleration and reverse.
70/30: Allows more throttle travel (70%) and less reverse travel (30%).
50/50 is the required setting for the T-Maxx with TRX 3.3 Racing
Engine installed.
Steering Trim
The electronic steering trim located on the face
of the transmitter adjusts the neutral (center)
point of the steering channel.
Multi-Function Knob
The Multi-Function knob can be programmed to
control a variety of functions. From the factory,
the Multi-Function knob controls steering
sensitivity, also known as exponential or “expo.” When the knob is turned
counterclockwise all the way to the left (default position), expo is off
and steering sensitivity will be linear (the most commonly used setting).
Turning the knob clockwise will “add expo” and decrease the steering
sensitivity in the initial range of steering wheel travel left or right from
center. For more detail on steering exponential, refer to page 10.
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. Turn on the receiver switch in the model. The switch is located on
the battery compartment.
3. Position the T-Maxx so that its front wheels are off the ground.
Make sure your hands are clear of the moving parts of the model.
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 receiver batteries.
5. When looking down
at the 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.
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.
Always turn your
transmitter on first.
Then start your engine.

Always turn your
receiver on second.

Remember, always turn the TQi transmitter on first and off last to
avoid damage to your T-Maxx 3.3. Never turn the radio off while
the engine is running.
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.
*Requires optional 4995X reverse kit.
