The Traxxas TQ 2.4 radio system uses the latest Direct Sequence Spread
Spectrum technology to provide superior signal quality, reliability and instant
response even in “noisy” conditions that can cause glitching and “hits” with
standard AM and FM systems. There is no need to monitor other frequencies
or channels for conflicts; the TQ 2.4 automatically locates and locks onto an
open frequency when you power up. Additional channels allow functions
such as lights, reversing/shifting transmissions, and other features to be
operated, in addition to the steering and throttle functions. The included
micro receiver fits easily in any application, and dual channel-1 inputs
eliminate the need for a Y-harness when using dual steering servos.

TQ-4 Radio System Adjustments
In addition to the electronic throttle and steering trim controls, your radio
system features throttle neutral adjustment and servo reversing switches.
• ThrottleTrim
The electronic throttle trim located on the face of the transmitter adjusts
the neutral (center) point of the throttle channel.
• SteeringTrim
The electronic steering trim located on the face of the transmitter adjusts
the neutral (center) point of the steering servo when the transmitter’s
steering wheel is at rest. Adjust this control to make the model drive
straight with no steering input at the wheel.
• Channel3Trim
This adjustment is located on the back of the transmitter and is accessible
using a
1
/
8
" (3mm) flat-blade screwdriver. Turning the adjustment
potentiometer (or “pot”) will set the neutral point of the servo plugged into
the receiver’s third channel.
• Channel4Trim
This adjustment is located on the back of the transmitter and is accessible
using a
1
/
8
” (3mm) flat-blade screwdriver. Turning the adjustment
potentiometer (or “pot”) will set the neutral point of the servo plugged into
the receiver’s third channel.
• Channel3Switch
The red rocker switch controls the transmitter’s third channel. A servo
plugged into Channel 3 will move to full travel in one direction when the
switch is in the “up” position, then move to the opposite end of its travel
range when the switch is in the “down” position. The channel 3 servo-
reversing switch allows you to select the servo’s direction of travel relative
to switch position.
• Channel4Switch
The toggle switch located just in front of the steering wheel operates the
fourth channel. The three-position switch allows you to hold the servo at
its center position, or select full-left or full-right travel by flipping the switch
up or down. The Channel 4 servo-reversing switch allows you to select the
servo’s direction of travel relative to switch position.
• TransmitterbindingSETbutton
This button is used to electronically “bind” the transmitter to the receiver.
See TQ 2.4 Transmitter Binding Instructions for details.
• ServoReversingSwitches
The servo reversing switches are located on the front of the transmitter,
next to the on/off switch. Moving a switch reverses the direction of the
corresponding servo. Each switch corresponds to a channel on the receiver
(see TQ 2.4 receiver image, opposite side). For example, if you turn the
steering wheel to the right and your wheels turn left, you would move
the Channel 1 switch to correct the servo direction. It may be necessary to
adjust the corresponding trim control after moving a switch.
• ThrottleNeutralAdjustment
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%).
Note: If you change the position of the Throttle Neutral selector, you
will need to reset the receiver’s throttle endpoints. See Setting the TQ 2.4
Transmitter Throttle Endpoints for the required steps. It is also likely that
you will need to reprogram your car’s electronic speed control or readjust
the throttle and brake linkages to operate properly with the new throttle-
neutral setting.
