Important LiPo Performance
and Care Information!
To get the most performance and safety from your LiPo
battery, please read and understand the following information.
●Always follow the manufacturer’s recommendation for
charging and maintaining your batteries.We would, however,
like to expand on this for R/C boating use.
●Never leave a charger and battery unattended while charging.
●Use only the recommended batteries and appropriate
charger.
●Refer to the instructions included with your charger for
proper battery charging procedure.
●For best performance and longest battery life, never charge
your LiPos at a charge rate higher than 1C. (1000mAh =
1amp, 2000mAh = 2amps and so on). Remove the battery
pack from the model and charge in a LiPo Sack (GPMP0751)
or other safe charge container.
●We have found it best to use only 80% of the rated mAh of
the battery pack per discharge (boat run).You will experience
rapid depletion of battery pack performance if you continue
to discharge your pack below the 80% usage target.
NOTE: Your Atlantic II Harbor Tugboat’s ESC has a stutter
bump warning system that warns you of low battery voltage.
This system starts its warning at 10.2V total giving you time
to bring the boat back to shore before the ESC cuts off at
9.2V.This is a built-in safety system for you, your boat and
your batteries. It’s important to note that a 2S pack (7.2V)
will not operate your boat or any battery pack (i.e. number of
cells) that falls below the listed warning and cut off voltages.
Although this system is in place we still recommend
adjusting your run times to not exceed 80% battery usage.
Always unplug and remove the battery from the boat
after use. NEVER leave your battery pack plugged into
the boat when not in use.
●Store your battery pack/s in a LiPo Sack (GPMP0751) or
other battery containment device. It is best to store them in
a cool, dry place and on a fire-resistant surface. It is also a
good idea to charge your batteries to either a full charge (if
you feel you will be using the packs frequently) or at 11.4V
for a 3S pack (or 3.8V per cell) for longer storage.

Safety Precautions
●AquaCraft products are to be used by ages 14 and over.
●Never ever attempt to swim after a stalled R/C boat. Do
not get in the water for any reason to retrieve your boat.
To aid in retrieving a stalled R/C boat, set up a fishing
reel with a tennis ball tied to the end of the line. Better
yet, get yourself a small Jon boat so you can row out
and pick up your boat. Remember to use a PFD any
time you enter your retrieval craft.
●Do not touch the propeller anytime the motor is running. Pay
close attention to items such as loose clothing, shirtsleeves,
ties, scarves, long hair or anything that may become
entangled in the spinning prop. If your fingers, hands, etc.
come in contact with the spinning propeller, you may be
severely injured.
●The speed and mass of this boat can inflict property damage
and severe personal injury if a collision occurs. Never run this
boat in the presence of swimmers or where the possibility
of collision with people or property exists.
●Electric motors produce heat. Do not touch any part of your
motor until it has cooled.
●This boat is controlled by radio signals, which are susceptible
to possible interference from other possible electrical noise.
● You might be enticed to operate your boat at a very far
distance. Please avoid “taking her out” too far. The radio
system is capable of 1000' or more of operation but radio
reception variables exist, causing possible loss of control.
●If weeds become entangled in the propeller, stop the motor
and unplug the battery before attempting to remove them.
●If your boat should happen to stall, water currents will slowly
carry it to shore. Keep in mind that the boat could be carried
to the opposite shore. When surveying areas to run your
boat, keep variables in mind such as wind direction and lake
size. It is not advisable to run R/C boats on any free-flowing
bodies of water such as creeks or rivers.
●Always remove the battery pack from the boat before
charging.

Understanding Your Transmitter
To help you better understand your transmitter and its functions,
here is a picture outlying the operation features, servo reversing
and receiver assignments (* not used with this product).
SERVO REVERSING AND RECEIVER ASSIGNMENTS
CH 1 = Steering (right stick, left and right)
*CH 2 = AUX 2 (momentary switch)
CH 3 = Throttle (left stick, up and down)
*CH 4 = AUX 1 (left stick, left and right)
Assembly Sequence
IMPORTANT NOTE: The transmitter is not water resistant and
should never come in contact with water!
Slide off the battery door from the back of the transmitter and
install 4“AA” batteries into the transmitter in the configuration
molded into the battery floor. Reinstall the battery door.
Turn the transmitter “ON” by shifting the power on switch to the
up position. The battery indicator light (LED) should glow red.
If the light is flashing and the transmitter beeping, the batteries
might be installed incorrectly or are low and need to be replaced.
To remove the cabin slide the “tool box” forward near the front
of the cabin.
Rotate the front of the cabin up and forward to remove it from
the hull.
Inside the cabin you will see two shorter wire sets with plug-ins.
Plug the two together. This is the connection from the lower
cabin to the upper cabin lighting system.

5
Inside the boat you will find two lighting plug-ins coming from
the ON-OFF switch for the lights. You will only be plugging
the cabin into one of the two plugs. Go ahead and plug this in.
knowing you might want to unplug and set the cabin aside to
make it easier to work on for now.
Next install the accessories. You will find them packaged in a
small plastic bag attached to the light mast. Remove the bag
and the accessories inside.
Install the RF antenna on the port side of the light mast. Carefully
slide this in place. If you want, you can place a small dab of
glue (medium CA glue or plastic model cement) to help hold
the part in place. Install the radar antenna the same way but
on the starboard side of the mast.
The center spire slides in from the bottom center of mast. You
can allow this to friction fit or glue as needed.

The completed assembly.
Install the Battery in the Atlantic II
Remove the provided “loop” strip from the battery tray and
attach it to your battery pack.
Install the battery into the boat as shown. Do not hook up the
main power battery until you are ready to operate the boat!
Next install two AA batteries into the battery holder located
on the radio tray.
If needed, one has access to the rear hatch by simply sliding
the latch forward and lifting off the cover.

Operation
With the transmitter on, plug a fully charged battery into the ESC.
You will hear the motor beep three times letting you know the
motor and ESC have power. Moving the left stick forward should
result in counter clockwise rotation of the propeller. Moving the
stick back should result in the propeller turning clockwise. If
this not correct, unplug the battery and switch revising switch
3 and test again. (Default switch position is down.)
NOTE: The throttle trim lever allows more or less reverse
power without changing the full forward operation. To do this,
simply plug the battery in with the throttle trim lever in the lowest
position. During power up the system will program to this trim
setting. This will provide the least amount of reverse power.
Moving the trim lever to the top and plugging the battery in will
provide the most amount of reverse power.You can position the
trim lever within the extents of the movement to custom adjust
the amount of reverse you want by simply adjusting the throttle
trim lever up or down and plugging in the battery.
1. Turn the power on to the transmitter and receiver (in
that order).
2. Place the boat in water that is at least 12” deep and
free of weeds, sticks and obstacles.
3. Advance the throttle to half speed and note if the boat
has a tendency to turn right or left. Adjust the steering
trim on the transmitter until the boat runs straight when
the steering is at neutral.
4. After you have completed a run, unplug the boat’s power
battery. This safely powers down the boat. Then, turn
off your transmitter.
IMPORTANT: If your boat takes on a large amount of water
and stalls in the middle of the lake, don’t worry, your boat has
foam floatation so it will not sink. You will, however, have
to retrieve the boat and remove the cabin hatch and battery.
Remove any water that might have entered and allow the boat
to fully dry before operating it again.
Maintenance
It is important to remove and re-lubricate the drive system
after a day of running.
Make sure the battery pack is unplugged. Use a needle oiler
to place one drop of oil on each end of the motor shaft. as
well as each end of the drive shaft where shown.
