Motor Capacitors Required: Ceramic capacitors should be properly

installed on every motor to prevent radio interference. These are
already installed on the factory Titan motor.

No Schottky Diodes: External schottky diodes are not compatible

with reversing speed controls. Using a schottky diode with the EVX-2
Marine will damage the ESC and void the 30-day warranty.

Installation
The EVX-2 Marine should be installed in a watertight compartment inside
the boat. The EVX-2 Marine speed control is NOT waterproof. It is NOT
designed to be submerged in water. The EVX-2 Marine speed control can
be seriously damaged if it is allowed to get wet. If your boat hull does not
have provisions for a sealed compartment, consider fabricating one from
a small Tupperware

or Rubbermaid

container. If possible, install the

receiver in the sealed compartment with the speed control. A template
is provided to cut out the hole for the speed control wiring gasket (Part
#1578). Make sure to seal any screw holes and the water line entry and
exit points with silicone sealer. Use ample silicone grease around the
wiring gasket to provide a
serviceable seal. Traxxas has
the following parts available
from the Villain EX that can
assist you in sealing a custom
fabricated radio box:

1574 - Antenna boot (rubber) (1)/ on-off switch cover (rubber) (1)
1577 - Boots, pushrod (2) (rubber, for steering rods)
1578 - Gasket, wire (for EVX/EVX-2 ESC) (1)/ silicone grease

Here are some tips for choosing a location for the speed control:

• The EVX-2 Marine does not use a conventional on/off switch. Pressing the

remote EZ-Set button turns it on and off. It is not necessary to install an
on/off switch into the wiring harness.

• Mount the speed control where you will have easy access to the plugs

and the EZ-Set remote.

• Mount the speed control so that none of the power components (wiring,

motor, ESC) contacts any part of the radio system, particularly the
antenna wire. The receiver should be mounted so the antenna wire can
be extended as far away from the speed control as possible. The antenna
wire should be extended vertically in the mast and not wrapped on the
chassis under the body. Excess antenna wire should not be coiled on
the chassis. Servo cables and the antenna wire should not cross or come
in contact with any of the motor or battery wires. These steps will help
reduce the possibility of radio interference.

• Graphite or metal chassis have been known to transmit radio noise

generated by the motor. If the receiver is to be mounted on the chassis,
position it so the crystal and antenna are as far away from the chassis as
possible. This may require you to mount the receiver on its side. This will
reduce the chance of picking up radio interference from the motor.

• When mounting the speed control with double-sided servo tape, clean

both application surfaces thoroughly with alcohol to remove any
grease, dirt, oil, fingerprints, etc. The surfaces must be perfectly clean for
maximum adhesion.

• The motors require capacitors to reduce the possibility of radio

interference. If your motors are not equipped with capacitors,
install the capacitors supplied with the EVX-2 Marine as shown in the
diagram below.

Water Cooling

Provisions must be made to provide cooling water to the heat exchanger

(heat sink). Use standard fuel tubing (Traxxas part #3147X). Position a
water pickup at the rear of the boat where it will extend into the high
pressure water at the transom. Traxxas makes a plastic water pickup as
part #1588, that includes the pickup, the backing plate, and hardware.
Otherwise, a short piece of brass tubing cut at a 45-degree angle on the
water pickup side will work. The water-cooled heat exchanger has two
separate chambers. Villain EX uses only one of the two chambers. Use
of both chambers may be beneficial in high current applications. Make
sure all water connections are secure to prevent leakage inside the sealed
compartment. The water
outlet tube should exit
the hull in an area that
is highly visible while
running the boat. A
steady stream of water
should always be
visible while the boat is
running at speed.

Transmitter Setup
Traxxas TQ Radio Systems
Before attempting to program your EVX-2 Marine, it is important to make
sure your TQ transmitter is properly adjusted (set back to the factory
defaults). Otherwise, you may not get the best performance from your
speed control.

The transmitter should be adjusted as follows:

1. Set the throttle neutral switch to the 70/30 setting. This adjusts the

transmitter’s throttle trigger throw to 70% for throttle and 30% for
reverse. Less experienced users may want to use the 50/50 setting to
limit the proportional control in forward.

2. Set the throttle trim control to the middle “0” setting.

3. Set the Channel 2 servo reversing switch to the left position.

Do not change the position of any of the servo reversing switches after
programming the EVX-2 Marine.

4. You are now ready to program your speed control.

Aftermarket (Non-Traxxas) Transmitters
The following instructions are provided as a general reference
only for those who are using non-Traxxas transmitters. Consult your
transmitter’s instructions for information on how to change the settings.

1. Set the High ATV (adjustable travel volume) or EPA (end point

adjustment) to the maximum setting. This is the amount of servo throw
at full throttle.

2. Set the Low ATV, EPA or ATL (low side only trim adjustment) to the

maximum setting. This is the amount of servo throw at full brakes
or reverse.

3. Set the throttle trim to the middle (neutral setting).

4. Set the throttle channel reversing switch to either position. Do not

change the switch position after programming.

5. Set the trigger throw adjustment to 50% throttle and 50% brake (either

mechanical or electronic).

6. Set the exponential setting (if equipped) to the zero or fully linear setting.

Aftermarket Receivers
The EVX-2 Marine is compatible with most
aftermarket receivers. By removing the tab on
the edge of the power connecter, the EVX-2
Marine can be plugged directly into some
models of Futaba®, Airtronics®, Hitec®, and JR®
receivers. Please refer to the manufacturer’s
wiring diagrams that came with your receiver.
On the EVX-2 Marine, the red wire is positive, the black wire is negative,
and the white wire is the control wire. Warning: On some older Airtronics®

radio systems, the positive and negative terminals are opposite of the
EVX-2 Marine and an adapter is required. Crossing the red (+) and black
(-) wires could damage the receiver and the EVX-2 Marine. Study the
manufacturer’s wiring diagrams closely, or consult your hobby dealer.

Setup Programming
(Calibrating your ESC and transmitter)
Read through all of the following programming steps before you begin.
If you get lost during programming or receive unexpected results, simply
unplug the battery, wait a few seconds, plug the battery back in, and
start over.

1. Place the boat on a boat stand. Always make sure

that objects and fingers are clear of the props. The
motors will not run during programming.

2. Connect two fully charged battery

packs to the EVX-2 Marine.

3. Turn on the transmitter (with the

throttle at neutral).

4. Press and hold the EZ-Set

button (A). The LED will first turn
green and then red. Release the
EZ-Set button.

5. When the LED blinks RED ONCE.

Pull the throttle trigger to the
full throttle position and hold it
there (B).

6. When the LED blinks RED TWICE. Push the throttle

trigger to the full reverse and hold it there (C).

7. When the LED turns solid GREEN, programming is

complete. The LED will continuously shine green
indicating the EVX-2 Marine is on and at neutral (D).

EVX-2 Marine Operation
To operate the speed control and test the programming, place the boat on
a stand so all of the propellers are off the ground. Always make sure that
objects and fingers are clear of the propellers.

1. With the transmitter on, press the EZ-Set button for ½ second, until the

LED shines GREEN, then immediately release the button. This turns on
the EVX-2 Marine. If you press and release too quickly, you may hear the
steering servo jump but the LED may not stay on. Press the button again
until the LED shines GREEN and then release. (Note: If the throttle is not
at neutral or if the throttle trim has been altered, the LED will turn off after
one second and the wheels may begin to drive.)

2. Apply forward throttle. The LED will turn off until full throttle power

is reached. At full throttle, the led will shine GREEN.

3. Return the throttle trigger to neutral. The LED will shine GREEN.

4. Move the throttle trigger forward again to engage reverse (Profile #1).

The LED will turn off. Once full reverse power is reached, the LED will
shine GREEN.

5. To stop, return the throttle trigger to neutral. Note that there is no

programmed delay when changing from reverse to forward. Use caution
to avoid slamming the speed control from reverse to forward. On high-
traction surfaces, this could result in transmission or driveline damage.

6. To turn the EVX-2 Marine off, press the EZ-Set button until the green LED

turns off.

Thermal Shutdown Protection
The EVX-2 Marine is equipped with thermal shutdown protection to guard
against overheating caused by excessive current flow. If the operating
temperature exceeds safe limits, the EVX-2 Marine will automatically shut
down and the remote LED will flash red. The LED will continuously flash red,
even if the throttle trigger is moved back and forth. After the speed control
cools down to a safe level, the LED will continuously shine green. The EVX-2
Marine will once again function normally.

EVX-2 Marine Profile Selection
The speed control is factory set to Profile #1. To change the profile,
follow the steps on described below. The speed control should be
connected to the receiver and battery, and the transmitter should be
