Your speed control was
adjusted to the radio from
the factory. It is possible
for the throttle trim control
on the transmitter to have
moved during transit
or while handling the
transmitter. If the motors
run when the model is
switched on, then move the
throttle trim control on the
transmitter until the motors
stop. If anything more
than a slight adjustment of
the throttle trim control is
required, then you should
readjust your speed control.
Refer to the adjustments
section on page 15.

Remember, always turn the
TQ transmitter on first and
off last to avoid damage to
your model.

When rechargeable batteries
begin to lose their charge,
they will fade much faster
than alkaline dry cells. Stop
immediately at the first sign
of weak batteries. Never turn
the transmitter off when the
battery pack is plugged
in. The model could run out
of control.

TQ Radio System Rules

Each time you prepare to run your model, you

must clear your frequency to be sure no one
else in the area is using the same channel as
you. There are six possible channels, numbered
1 through 6. Each is represented by a color.
Look at the crystal plugged into the back of
your transmitter to determine which channel
your model is assigned to.

Always turn your TQ 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.

Always have the transmitter turned on before plug in

the battery.

Always use new or freshly charged batteries for the radio

system. Weak batteries will limit the range of the radio signal
between the receiver and the transmitter. Loss of the radio
signal can cause you to lose control of your model.

TQ Radio System Setup

The TQ Radio System was pre-adjusted at the factory. The
adjustment should be checked, before running the model,
in case of movement during shipping. Here’s how:
1. Fully extend the chrome antenna mast on the transmitter and

turn the switch on. The red indicator light on the transmitter
should be solid red (not flashing).

Elevate the model so that all four tires are off the ground.

If you are holding the model, grip it firmly. Make sure your
hands are clear of the moving parts of the model.

3. Plug the battery pack in the model into the speed control.

4. The on/off switch is integrated into the speed control. With

the transmitter on, press the EVX-2 set button for ½ second, until
the LED shines GREEN, then immediately release the button. This
turns the model on (see page 15 for more on EVX-2 setup and
operation). To turn the EVX-2 off, press the set button until the
green LED turns off.

Always disconnect your batteries when the

model is not in use.

5. Turn the steering wheel on the transmitter back and forth and

check for rapid operation of the steering servos. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak batteries.

6. When looking down at model, the front wheels should be

pointing straight ahead. If the wheels are turned slightly to
the left or right, slowly adjust the steering trim control on the
transmitter until they are pointing straight ahead.

7. Operate the throttle trigger to ensure that you have full forward

and reverse operation, and that the motors stop when the
throttle trigger is at neutral.

8. Once adjustments are made, turn off your model, followed by

the hand held transmitter.

Range-Testing the TQ Radio System

Before each running session with your model, you should range-
test your radio system to ensure that it operates properly.

1. Turn on the radio system and check its operation as described

in the previous section.

2. Have a friend hold the model. Make sure hands and clothing are

clear of the wheels and other moving parts on the model.

3. Make sure your transmitter antenna is fully extended, and then

walk away from the model with the transmitter until you reach
the farthest distance you plan to operate the model.
