Traxxas TRX Power System (optional)
The optional Traxxas TRX Power System can be
purchased separately to power the radio system
in the Jato 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 Jato (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 Jato 3.3.
