Installing Receiver Batteries
The radio receiver in your S-Maxx uses 4 AA batteries.The battery
holder for the receiver batteries is located underneath the battery
cover.The battery cover can be identified by the on/off switch.
1. Remove the battery
cover by removing
the two 3x10mm
buttonhead cap
screws from the cover.
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. Insert the battery holder into the battery cover.
4. Reinstall the battery cover and secure with the
screws (see sidebar!).
To prevent losing control of your model,it is important to stop at
the first sign of weak receiver batteries.Visible warning signals
include sluggish steering response and shortened radio range.
Direct the battery wires
through the slot in the
battery cover.
If the
wires are not properly
routed,they may become
broken or shorted,causing
radio system failure and
loss of control.
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 S-Maxx 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 S-Maxx. 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 S-Maxx (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 S-Maxx.
Consult your hobby dealer for purchasing information.
