NITRO 4-TEC 3.3
INSTALLING TRANSMITTER BATTERIES
Your TQ 2.4GHz transmitter uses 4 AA batteries. The battery
compartment is located in the base of the transmitter.
1. Remove the battery compartment door by pressing the tab
and lifting the door up.
*
2. Install the batteries in the correct orientation as indicated in the
battery compartment.
3. Reinstall the battery door and snap it closed.
4. Turn on the transmitter and check the status indicator for a solid
green light.
If the status LED flashes red, the transmitter batteries may be
weak, discharged or possibly installed incorrectly. Replace with
new or freshly charged batteries. The power indicator light does
not indicate the charge level
of the battery pack installed
in the model. Refer to the
Troubleshooting section on page
37 for more information on the
transmitter’s Status LED codes.
INSTALLING RECEIVER BATTERIES
The radio receiver in your Nitro 4-Tec uses 4 AA batteries. The receiver
battery holder is located underneath the top plate, just to the right of
the fuel tank.
1. Press the tab on
the reusable zip
tie to release the
battery holder.
2. Remove the battery
holder and install 4
AA alkaline batteries.
Make careful note of
the battery polarity by comparing against the
diagrams in the battery holder.
3. Stretch a rubber balloon over the battery
holder to prevent fuel contamination.
4. Install the battery holder into the car
and secure it to the top plate with the
reusable zip-tie. Make sure the battery holder
is secure in the model and will not come
loose. If the tie wrap is loose, it will interfere
with the middle drive belt.
Traxxas TRX Power System (optional)
The optional Traxxas TRX Power System can
be purchased separately to power the radio
system in the Nitro 4-Tec 3.3. Benefits include
the economy of a rechargeable 5-cell nickel
metal hydride (NiMH) battery pack that replaces
AA alkaline batteries, and increased voltage
for dramatically improved servo performance.
The TRX Power Charger (Part #3030X) is a peak-
detecting unit that will charge the RX Power
Pack (Part #3036 flat pack or #3037 hump pack) in about one hour.
The peak detection circuitry automatically shuts off the charger when
the maximum charge has been achieved. The TRX Power Charger also
includes a 7.2V adapter for charging 7.2V EZ-Start batteries.
The TRX Power Charger can operate on either AC or DC power. A special
wiring harness for Nitro 4-Tec (Traxxas part #3034) that includes a handy
external charging jack is required.
The optional DC car adapter (Part #3032) features a
tangle-free, extra long wire and integrated fuse. The
long charging cord allows the model to remain outside
the car while charging. Caution! Never charge batteries
in an enclosed car interior or while driving. Never leave
charging batteries unattended. Monitor them closely.
Traxxas’ integrated TRX Power System is the easiest way to add the
power and economy of rechargeable batteries to your Nitro 4-Tec 3.3.
Consult your hobby dealer for purchasing information.
*Always keep your Quick Reference Guide in your transmitter.
If the radio system doesn’t
appear to work when the
transmitter and receiver
switches are turned on, check
for correct battery installation.
