Traxxas TQ 2.4 User manual

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.
• ThrottleTrim
The electronic throttle trim located on the face of the transmitter adjusts
the neutral (center) point of the throttle channel.
• SteeringTrim
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.
• Channel3Trim
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.
• Channel4Trim
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.
• Channel3Switch
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.
• Channel4Switch
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.
• TransmitterbindingSETbutton
This button is used to electronically “bind” the transmitter to the receiver.
See TQ 2.4 Transmitter Binding Instructions for details.
• ServoReversingSwitches
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.
• 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%).
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.

Installing Transmitter Batteries
Your TQ-4 transmitter uses 8 AA
batteries. The battery compartment is
located in the base of the transmitter.
1. Remove the battery compartment
door by pressing the tab and lifting
the door up.
2. Install the batteries in the correct
orientation as indicated in the
battery compartment.
3. Reinstall the battery door and snap it closed.
4. Turn on the transmitter and check the power indicator for a solid red light.
If the power indicator light flashes, then the transmitter batteries are weak,
discharged or possibly installed incorrectly. Replace with new or freshly
charged batteries. The power indicator light does not indicate the charge
level of the battery pack installed in the model.
TQ 2.4 Transmitter 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, follow these instructions. Note: the receiver must be
connected to a 4.8-7.2v power source for binding.
1. Press and hold the transmitter’s SET button as you switch transmitter on.
The SET LED will flash.
2. Press and hold the receiver’s LINK button as you switch receiver on.
The LINK LED will flash.
3. When both LEDs stop flashing (this will take just a moment or two), the
system is bound and ready for use. Confirm that the steering and throttle
operate properly before driving your model.
Setting the TQ 2.4 Transmitter Throttle Endpoints
TheTraxxasTQ2.4GHzradiosystemispre-setatthefactoryandisready
foruse.If you wish to reprogram the receiver to make certain the throttle
endpoints are correctly set, follow the steps below.
1. Switch the transmitter and receiver on.
2. Press and hold the receiver’s LINK button until the LED blinks red once then
switches off. Release the LINK button.
3. Pull the throttle trigger to the full-throttle position and hold until the
receiver’s LED blinks red twice.
4. Push the trigger to full brake and hold until the red LED blinks twice.
5. Return the trigger to neutral. The LED will blink three times then remain on
(the LED will shine green if fail-safe is active, or red if fail-safe is disabled).
TQ 2.4 Transmitter Fail-Safe Operation
When bound to the transmitter, the 2.4GHz Micro Receiver automatically
sets its fail-safe position to throttle neutral. This means the receiver will
automatically return the throttle setting to neutral in the event of signal
loss due to interference, low battery power, or accidentally switching the
transmitter off while driving. When powered on, the receiver’s green LED will
glow to indicate fail-safe mode is active. If the LED glows red, the fail-safe
mode has been deactivated. Use these steps to reactivate the fail-safe system:
1. Switch the transmitter and receiver on.
2. Press and hold the receiver’s LINK button. The LED will flash once, then
turn off. Continue to hold the LINK button. After about three seconds, the
LED will flash on and off. It will continue flashing as long as you hold the
LINK button.
3. Release the LINK button. The LED will now light green and glow steadily,
indicating fail-safe mode is active.
Should you ever wish to deactivate the fail-safe mode (for example, when
using a speed control that has its own fail-safe circuitry), simply repeat the
steps above.
