INTRODUCTION

Congratulations and thank you for purchasing SWORDFISH High performance sensorless
Brushless Motor Electronic Speed Control. The SWORDFISH, brushless ESC represents a
latest technologies, providing all the features and robust design qualities.

SAFETY NOTE

WARNING: This is an extremely powerful brushless motor system. We strongly
recommend you to take extreme care for your own safety before performing calibration and
programming functions with this system. Please keep your hands, hair, cloth, clear from the
propeller of an armed high performance system.

NO REVERSE VOLTAGE!

Reverse battery polarity can damage ESC & void warranty. Disconnect battery immediately if
a reverse connection occurs.

DISCONNECT BATTERIES WHEN NOT IN USE

Always disconnect the battery pack from the speed control when not in use to avoid short
circuits and possible fire hazard.

2)Mount Speed Control in Boat

Use double-sided tape to mount the speed control in boat(do not use CA glue).

3) Soldering Battery & Motor Connector

“ Pre-tin” the wire by heating the end and applying solder until it is thoroughly
covered.
Adding a battery connector to your swordfish 120 marine speed control.Solder the three
leads to your motor(recommended) or solder your choice of connectors to the motor and
controller leads.

CAUTION: By very careful not to splash yourself with hot solder.

4) Plugging In Motor Leads

With a brushless system, there is no polarity on the MOTOR side of the controller. After the
throttle calibration, if the motor runs backwards with forward throttle, simply swap any two
of the motor/controller connections and it will reverse the rotation of the motor.

5) Connecting to the receiver

Connect the throttle lead (the three color wires with a connector on the end) to the throttle
channel on your receiver (usually channel 2). Don’t connect a battery to the receiver, as the
SWORDFISH will supply power to the receiver and servo through the throttle connector.

2 - 6 LI-PO CELLS ONLY

Never use fewer than 2 or more than 6 LIPO cells in the vehicle's main battery pack. The
SWORDFISH handles up to 6S LIPO input (25.2 Volts MAX).

TRANSMITTER ON FIRST

Turn on the transmitter first THEN turn on the speed control.

INSULATE WIRES

Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short
circuits, which can damage ESC.

ESC CONNECTION

1)Plan Speed Control Placement
Choose a location for the speed control. To prevent radio interference place the speed

control as far away from the radio receiver as possible and keep the power wires as short
as possible.

6) Connecting water cooling tube

Attach the input and output tubes to one end of the controller. Cut a section approximately
100mm(3.93") long and use it to connect the tubes at the opposite end of the
SWORDFISH. Make sure the flexible tubes curve gently with no tight bends. Please see
the diagram below for reference.

Water Cooling Tube

(Users must provide their own water cooling tube.)

1)Normal(D)*

2)Reverse

2)50%(D)*

This is default setting. The actual motor direction will be
determined by how the wires are connected.

This is opposite the default direction.

From this poi nt on, when you connect batteries and tu rn on the switch, the ES C will
give the ini tializa tion tone, and the ar ming tone will rin g s econd or two later. If the ESC

ESC PROGRAMMING

1)Manual Programming
Manual Programming SWORDFISH is as simple as answering a few questions.The

SWORDFISH asks questing by beeping a setting number, followed by the possible setting
values. There are eight settings that can be programmed in the SWORDFISH.

You must answer "yes" or "no" to the setting values as they are presented by SWORDFISH.
When you enter programming mode the ESC will emit a sequence of beeps that tell
you which programming step you are in. There are two parts to the beep sequence.
The first set of beeps indicates the 'Setting Number (Question), e.g. Reverse
Type, and the second set of beeps indicates a Setting Value, e.g. Reverse Lockout.
Answering "No" to a Setting value will cause the ESC to ask for the next value in that
section. After a "Yes" answer is accepted, the ESC knows you aren't interested in any
other option in that section, so it skips to the first option in the next section.

Note: If you answer "no" to all Setting Values for a particular Setting Number, the ESC
will keep whatever value had been previously programmed. Only by answering "Yes" to
a Setting Value will the ESC store/change that value.
