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 Nitro 4-Tec 3.3 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 13.
Always turn your
transmitter on first.

Always turn your
receiver on second.
Then start your engine.
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.
