Revo 3.3
The TRX 3.3 Racing Engine
The Traxxas EZ-Start brings the convenience of push-button electric
engine starting to your Revo. The EZ-Start consists of a hand-held
control unit and an on-board motorized starter.
Power for the EZ-Start system comes from a 7.2-volt rechargeable
battery pack installed in the hand-held control unit (battery
sold separately).
The engine glow plug is heated automatically by the EZ-Start system,
eliminating the need to keep up with a separate glow plug igniter.
The voltage to the glow plug is kept constant, regardless of the load
placed on the starter by the starter motor.
The “Glow Plug” LED (light emitting diode) on the control unit
indicates the condition of the glow plug.
The “Motor” LED indicates the status of the EZ-Start electric
starter motor.
The cush drive mechanism in the drive unit prevents damage to the
gears caused by engine kickback.
Smart Start
™
protection circuitry prevents damage to the motor by
cutting power if the load on the motor or other electronics exceeds
safe limits.
Charging the EZ-Start Battery with the TRX Power Charger
The included TRX Power Charger can be used to charge the EZ-Start
battery pack.
1. Set up the charger as described on
page 12 using either the A/C power
supply or optional D/C adapter.
2. Plug the 7.2-volt battery adapter
into the charger output cord.
3. Connect a 7.2-volt battery pack to
the charger output cord (adapter).
4. The green light on the charger should begin to flash quickly,
indicating that fast charging is in progress.
5. 1500mAh or lower capacity: When the light turns solid green (not
flashing), the battery pack is fully charged and ready for use.
1500mAh or higher capacity: The TRX Power Charger will
automatically shut off after 90 minutes of fast charging time. Batteries
with 1500mAh or higher capacity need more than 90 minutes of fast
charge time. Multiple charge cycles will be required for a fully peaked
charge (solid green light). Refer to the chart below.
*Based on a nominal charge rate of 900mA.
Installing the EZ-Start Battery
The EZ-Start system requires a fully charged 7.2-volt rechargeable NiCad
or NiMH battery pack (not included). Use a charger (not included)
designed for 7.2-volt battery packs. Charge the battery according to the
charger manufacturer’s directions.
1. Press the tab in the end of the battery compartment door to open.
2. Plug a fully charged 7.2-volt battery
pack into the connector inside.
3. Twist the battery two or three
times to twirl the battery plug
wires. This helps hold the wire
and battery in place when the
battery is installed in the
compartment.
4. Install the battery into the
compartment and press the wires
securely into place.
5. Snap the battery compartment
door back on and lock the end tab.
The Traxxas EZ-Start Electric Starting System
Use the Right Charger:
The most convenient type
of charger is an AC peak-
detecting charger that
plugs directly into an AC
wall outlet. It contains
special peak-detection
circuitry that automatically
shuts the charger off when
the battery is fully charged.
If you’re using a 15-minute
timed charger, always fully
discharge the battery pack
before each charge. Some
high mAh battery packs
(1500 mAh or higher)
require more than the
standard 15 minutes of
charge time. If the battery
pack is cold after 15
minutes of charging, add
another 5 minutes of charge
time. Closely monitor the
battery pack and stop
charging it when it begins
to feel warm to the touch.
Never leave a battery
charging unattended.
Always follow charger
manufacturer’s instructions.
Inexpensive overnight wall
chargers may also be used.
