The Traxxas TQ-3 Radio System

15

Spray a little window
cleaner on the
antenna wire to

make it easier to push
through the antenna tube.

Don’t shorten the
length of the
antenna wire. Its

length is tuned to the
frequency band; cutting it
could severely shorten the
radio system’s range.

Don’t push the
transmitter antenna
down from the top.

Pull it down from the
bottom, one segment at a
time, to prevent binding and
kinking the antenna mast. 

Setting Up the Antenna

You must install the antenna mast (tube) before you operate
your E-Maxx. You’ll find the plastic antenna tube and tip in the
bag with your manuals and documentation.

1.

Locate the black antenna wire that exits the receiver. The
E-Maxx receiver is mounted in the front of the chassis.

2.

Pull the wire straight with your fingers and then insert the
end of the wire into one end of the antenna tube. Push the
wire all the way through the antenna tube.

3.

Pull the remaining wire through the antenna tube, and then
insert the base of the antenna tube into the molded post on
the chassis.

4.

Fold the remaining antenna wire over the top of the tube
and secure it with the antenna tip.

5.

On the transmitter, always fully extend the telescoping
antenna when running your E-Maxx. Make a habit 
of holding the transmitter so that the antenna points 
straight up.
