7.2v BATTERY PACK AND CHARGER

The EZ-Start™ electric starter requires a

7.2 volt rechargeable nicad battery pack.
The battery pack straps to the bottom
of the EZ-Start™ control box with
the supplied tie wraps. The battery
pack must be 

fully charged

in order

to start the engine. It can be
recharged with an overnight “wall
charger”, a peak-detecting charger, or
a 15-minute quick charger. All are available from a hobby dealer.

REQUIRED EQUIPMENT

To operate the T-Maxx, you will need these additional items. All of

these items should be available from your hobby shop.

1. “AA” size batteries for your transmitter(8) and receiver(4)
2. Small Phillips head and flat screwdrivers (for adjustments)
3. After-run oil (to protect the engine from corrosion)
4. Spare glow plugs (standard plug, Traxxas part #3230; or 

heavy-duty plug, Traxxas part #3231).

5. In-line fuel filter (recommended)
6. Spare fuel line (recommended)
7. Hobby-quality, thin CA glue for the tires
8. Hobby knife

THE TQ-3 RADIO SYSTEM  

The T-Maxx model 4910 is equipped with the 3-channel TQ-3
radio system. The following radio system terms will be used
throughout the rest of these operating instructions.

THREE-CHANNEL RADIO SYSTEM

- The radio system in your

model consists of the RECEIVER, the TRANSMITTER, and the
SERVOS. It has three channels, one to operate the throttle, one to
shift the transmission, and one to operate the steering.

TRANSMITTER

- The TRANSMITTER is the hand-held radio unit

which sends throttle and steering instructions to the model.

RECEIVER

- The RECEIVER is the radio unit inside the model

which receives signals from the TRANSMITTER and relays them
to the SERVOS.

SERVO

- The SERVOS are the small motor units in the model

which operate the steering, shifting and throttle mechanisms.

FREQUENCY BAND

- The FREQUENCY band is the radio 

frequency that the transmitter uses to send signals to the model.
All Traxxas RTR models operate on a 27 MHZ FREQUENCY BAND.

CHANNEL

- The 27 MHZ FREQUENCY BAND is divided into 6

CHANNELS, so that up to six cars can be operated simultaneously.
These CHANNELS are referred to by their number and flag color.
The chart below lists the channels and their flag colors.

CRYSTAL (X-TAL)

- The CRYSTAL is the plug-in device that

determines which channel the RADIO SYSTEM will operate on.
For each CHANNEL, there are two CRYSTALS, one for the
RECEIVER and one for the TRANSMITTER. Of those two
CRYSTALS, the one marked with the lower number (.455 MHZ
lower) must be inserted in the RECEIVER.

CLEARING YOUR  FREQUENCY

- CLEARING your frequency

means checking to be sure no one else in the area is operating
on the same CHANNEL. You should always do this before operating
your model.

NICAD (Ni-Cd)

- These terms stand for rechargeable, nickel

cadmium batteries. These batteries are most economical and
can be recharged up to 500 times.

NEUTRAL POSITION

- The NEUTRAL POSITION is the standing

position that the SERVOS seek when the TRANSMITTER controls
are at neutral.

TRIM

- TRIM is the fine-tuning adjustment of the NEUTRAL

POSITION of the SERVOS. This adjustment is made by turning the
throttle and steering trim knobs on the face of the TRANSMITTER.

INSTALLING TRANSMITTER BATTERIES

Install 8 “AA” batteries into the bottom of the
transmitter as shown in the drawing.
