SkyRC Swordfish 120A ESC for Marine User Manual
Water cooled, Instruction manual, Marine speed control
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.
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 - 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.
Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short
circuits, which can damage ESC.
MARINE SPEED CONTROL
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
Use double-sided tape to mount the speed control in boat(do not use CA glue).
“ Pre-tin” the wire by heating the end and applying solder until it is thoroughly
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
CAUTION: By very careful not to splash yourself with hot solder.
3) Soldering Battery & Motor Connector
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.
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.
(Users must provide their own water cooling tube.)
