TQ Radio System Controls
The Traxxas TQ Radio System
There are two settings available:
50/50: Allows equal travel for both
acceleration and braking.
70/30: Allows more throttle travel
(70%) and less brake travel (30%).
50/50 is the required setting for Nitro 4-Tec
with the TRX 3.3 Racing Engine.
Electronic Throttle Trim
The electronic throttle trim located on the face of the transmitter adjusts
the neutral (center) point of the throttle servo when the servo is at rest.
This control has been preset for you at the factory. If necessary, adjust
the control so that the carburetor is at idle, and the brakes are not
applied (the model will roll freely). Do not use the throttle trim to raise
or lower the engine idle speed. Make the idle speed adjustment on the
carburetor.
Electronic Steering Trim
The electronic steering trim located on the face of the transmitter
adjusts the neutral (center) point of the steering servos when the servos
are at rest. Adjust this control to make the model drive straight with no
steering input at the wheel.
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, as shown
below. For example, if you turn the steering wheel to the right and your
front 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
. The default
position for the servo reversing
switches is shown.

adjustment by pressing the button and sliding it to the desired position.
