AquaCraft Motley Crew User Manual

INTRODUCTION & DESCRIPTION CHANGES

Thank you for purchasing the AquaCraft Motley Crew. We at
AquaCraft want the time you spend with your boat to be safe, fun
and successful. If for any reason you feel this R/C model is not for
you return it to your place of purchase immediately. Your hobby
dealer cannot accept returns on any model after fi nal assembly or
after your boat has been operated.

AquaCraft products are to be used by ages 14 and over.

All pictures, descriptions, and specifi cations found in this instruction
manual are subject to change without notice. AquaCraft maintains
no responsibility for inadvertent errors in this manual.

NOTES ABOUT USING LIPO BATTERIES IN YOUR BOAT:

The Motley Crew uses the AquaCraft 60amp ESC. This ESC has a
built in stutter bump system that cycles the power to the motor
when the battery voltage reaches 12V. This is designed to warn
you of impending low battery voltage and subsequent shut down.
It also has a 10.8V battery cut off safety system that shuts the
power down to the motor so not to damage the batteries.

Having said this: As a rule of thumb we have found it best in very
high current draw applications like an RC boat not to use more
than 70% of the rated capacity of the battery pack, per run. We
have also found that when in doubt and using the recommended
propellers you can expect to use about 1000mAh (give or take)
per minute of operation. Using this you can better judge your runs
knowing you’re taking the very best care of your battery pack
investment.

ITEMS INCLUDED

➧ Motley Crew Brushless Catamaran

PARTS NEEDED TO COMPLETE YOUR MODEL

❏ 4 – AA Batteries (Transmitter)
❏ Battery packs (2)
❏ Charger

For your convenience we have listed below a few different battery
and charger options. It is also important to note that chargers come
in both DC and AC/DC versions. DC charger requires a 12V power
supply like a 12V car battery or bench top power supply to power
up the charger. AC/DC chargers allow you to plug the charger into a
120V house outlet or DC power supply, therefore making them more
convenient for most charging situations.

GrimRacer Says: It is best to test this by

™

making a timed 2-minute run, then charging

the batteries back up and noting the amount
of mAh the pack allowed back in. Do this each and every time
you make a prop change or any other signifi cant change to your
setup! Then adjust your driving time so you don’t go over the
70% usage mark.

Also keep in mind that car packs (hard case) could be used. But if
you get them wet they can store water causing the internal metal
parts of the pack to corrode; in turn causing short pack life. We
highly recommend the use a dedicated marine LiPo packs.

SAFETY PRECAUTIONS

➧ Never, ever, attempt to swim after a stalled RC boat. DO NOT get

in the water for any reason to retrieve your boat. Your Motley
Crew has fl otation added to the interior of the hull and the cowl.
It will not sink. To aid you in retrieving a stalled RC boat you can
use a fi shing reel with a tennis ball tied to the end of the line. Or
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 equally

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 fi ngers, hands, etc. come in contact with the
spinning propeller, you may be severely injured.

➧ The speed and mass of this boat can infl ict 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.

➧ This boat is controlled by radio signals, which are susceptible to

possible interference from RF sources. It is a good idea to pre­check the system to make sure it’s operating properly before you
launch your boat.

➧ If your boat should happen to stall, water currents will slowly

carry it to shore. The bad news is the boat could be carried to the
opposite shore. When surveying areas to run your model, keep
variables in mind such as wind direction, size of the lake, etc. It is
not advisable to run R/C boats on any free-fl owing bodies of water
such as creeks or rivers.
