•USING THE 4-CELL BATTERY PACK:
On some applications, such as marine use, the 4-cell battery
pack can be used in conjunction with the electronic or mechanical
speed control. The red (positive) wire in the e.s.c. servo cable
must be removed from the plug and taped to prevent short cir-
cuiting before connecting it to the “channel-2” receptacle. Plug the
4-cell battery pack into the “battery” receptacle. The advantage
with this setup is that it gives you complete, full-power control of
the servos when the main battery pack is almost completely dis-
charged.
ANTENNA SETUP:
1.) Most R/C models come equipped with a
plastic antenna tube, antenna tube mount, and
an antenna tip. If you do not have these items,
they can be purchased from your local hobby
dealer. Route the receiver antenna wire
through the plastic antenna tube and then
insert the tube into the holder mounted in the
chassis. Fold the excess wire over the top of
the antenna tube and secure it with the antenna
tip. Under no circumstances should you ever
cut your antenna wire. Its length is specially
tuned to the frequency band, and cutting it
could severely shorten the radio’s range.
2.) Insert the chrome telescopic antenna into
the hole in the top of the transmitter and screw
it down until it stops.
The transmitter antenna
must be extended fully during use.
BASIC OPERATION:
1) Slide the on/off switch on the transmitter to the “on” position.
Check for a solid red light (not flashing). If the light is flashing,
the transmitter batteries are weak and should be replaced. The
red light does not indicate the condition of the batteries in the
model, only the transmitter. Weak batteries in either the model or
the transmitter will cause the range of your model to be limited,
and you could lose control.
2) Install a freshly-charged battery in the model. Set the rear of
the model on a block so that the rear tires are not touching the
ground. If your model has an on/off switch, turn the switch on.
Now, plug the battery in. *Note Traxxas ready-to-run models with
mechanical speed controls do not use an on/off switch. Plugging
the battery in turns the system on, removing it turns it off.
3) If the motor started running when you plugged in the battery
pack and/or turned the model on, then slowly adjust the throttle
trim on the transmitter until the motor stops running. (For electronic
speed controls, adjust the neutral control on the speed control. See
the “Electronic Speed Control” section.) Now operate the throttle
trigger to ensure that you have full forward and reverse operation,
and that the motor stops when the throttle trigger is at neutral.
4) Adjust the steering trim on the transmitter so that the front
wheels are pointing straight ahead. Now operate the steering
wheel to ensure that the steering works properly with no binding.
If the steering or throttle servos seem sluggish, then check to be
sure that either the main battery pack and/or the 4 “AA” receiver
batteries are fully charged.
5) Drive the model slowly at first, until you become accustomed
to the controls on the transmitter.
TRANSMITTER CONTROLS:
THROTTLE TRIM/ STEERING TRIM:
On electric models with a mechanical speed control, adjust the
throttle trim so that the model will stand still without trying to
move forward or backwards. Adjust the steering trim so that the
model will drive straight without veering to the left or right.
THROTTLE NEUTRAL ADJUST:
The throttle neutral adjustment is located on the transmitter
face(see illustration on page 2) and controls the amount of
desired forward and reverse travel of the throttle trigger. There
are two settings, 50/50 which gives you the same amount of
throttle travel in both forward and reverse, and 70/30 which gives
you more travel for throttle and less for reverse. Change the
adjustment by pressing the button and sliding it to the desired
position. The drawings below show how the settings are
arranged. Always use the 50/50 setting when using a mechanical
speed control or forward/reverse electronic speed control. Use
the 70/30 setting with a forward/brake electronic speed control or
Traxxas fuel-powered models. This setting provides more propor-
tional control over your forward speed. If you change this adjust-
ment, your transmitter throttle trim will have to be reset. In some
cases, the throttle servo may have to be re-centered with the
throttle trim adjustment reset at “zero” (see “centering your servos”).
SERVO REVERSING SWITCHES:
On the front of the transmitter there are two switches, one for
throttle and one for steering. Moving the switches reverses the
direction of the servo. For example, if you turn your steering
wheel right and the model moves left, then switch the steering
servo reversing switchto correct the servo direction. The electronic

CAUTION: When nicad batteries begin to lose their
charge, the voltage will drop much faster than alkaline
dry cells. Stop immediately at the first sign of weak
nicad batteries.
IMPORTANT:
Always turn the transmitter on first before you connect
the battery pack in your electric model. If you do not, the
model will appear to malfunction by running out of control.
(Remember, the transmitter is on first and off last.)
On fuel powered models, always make sure that the
radio system is on and functioning properly before
starting the engine.
