 Revo 3.3

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. 

  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

The included charger can be used to charge the included EZ-Start 
battery pack. 

1.

  Plug the charger into the wall. The LED on the charger should  

glow green. 

2.

  Connect the included EZ-Start battery pack to the charger output 

cord. The LED will glow red indicating the battery is charging.

3.

  The battery should charge for approximately 4 

½

 hours. The LED 

will turn green when the battery is fully charged.

Installing the EZ-Start Battery
1.

  Press the tab in the end of the battery 

compartment door to open (A).

2.

  Plug a fully charged 7.2-

volt battery pack into the  
connector inside (B).

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 (C).

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 (D).

Using the EZ-Start

Your EZ-Start controller plugs into a 4-prong receptacle in the center of the 
bed on your Revo 3.3. When the red button on the controller is pressed, 
the EZ-Start motor begins to spin the engine and power from the control 
unit heats the glow plug. Assuming all settings and preparations are 
correct, the engine should start almost immediately.

Each of the two status indicator LEDs on the hand-
held control unit, the 

Motor 

LED and the 

Glow Plug

 

LED, should light green while starting. If either LED 
fails to light while starting, there is a fault indicated 
with that function.

If the Glow Plug LED fails to light, the glow plug may 
be bad, or the glow plug wire may be damaged or 
disconnected.

If the Motor LED fails to light and the starter fails to 
operate, then the EZ-Start is in protection mode.

Using Other Chargers

Another convenient option 
for charging the included 
battery is an AC peak-
detecting charger that 
plugs directly into an AC 
wall outlet, such as the 
TRX Power Charger, Part 
#3030X. It contains special 
peak-detection circuitry 
that automatically shuts the 
charger off when the battery 
is fully charged.

Caution

: Never use a 

15-minute timed charger to 
recharge your model’s battery 
packs. Overcharging may 
result, causing damage to the 
battery packs.
