TQ 2.4GHz RADIO SYSTEM CONTROLS
Automatic Fail-Safe
The TQ 2.4GHz 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.
TQ RADIO SYSTEM RULES
Always turn your TQ 2.4GHz 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.

THE TQ 2.4GHz RADIO SYSTEM
TQ 2.4GHz 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 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 TQ 2.4GHz RADIO SYSTEM
The TQ 2.4GHz 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 rear shock tower.
3. Position the T-Maxx so that its front wheels are off the ground.
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 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.
Remember, always turn the TQ-3 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.
