Installing the 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.

Nitro 4-Tec 3.3
The Traxxas TQ Radio System
If you use rechargeable
batteries in your receiver,
be aware that when they
begin to lose their charge,
they lose power much more
quickly than regular
alkaline batteries. Signs of
weak receiver batteries
include sluggish steering
response and shortened
radio range. Caution:
Discontinue running your
Nitro 4-Tec at the first sign
of weak batteries to avoid
losing control.
If the radio system doesn’t
appear to work when the
transmitter and receiver
switches are turned on,
check for correct battery
installation.
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.
