AquaCraft Lucas Oil AQUB2105 User manual

Never attempt to swim after a stalled RC boat.
Never operate your RC boat while standing in the water.
Never operate your RC boat in the presence of swimmers.
Always use a Personal Flotation Device (PFD) when boarding and operating your retrieval craft, i.e. Jon boat, or duck boat.
NOTE: Because of the sharp running hardware included with this RC boat we do not recommend a rubber blow up raft.
RC boat running hardware is very sharp. Be very careful when working on and around the metal parts.
While the motor is running pay close attention to the propeller. Do not come in contact with the propeller at any time the
engine is running or serious injury will result.
AquaCraft products are to be used by ages 14 and over.

PARTS NEEDED TO COMPLETE YOUR MODEL:
4 – AA Batteries (Transmitter)
Two (2) LiPo Battery Packs
LiPo Compatible Battery Charger
For your convenience we have listed a few different battery and
charger options. It is also important to note that chargers come
in both DC and AC/DC versions. A DC charger requires a 12V
power supply like a 12V car battery or bench top power supply
for power. 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.
NOTE: If you purchased the Rx-R model, you will need to install
a 2-channel (or greater) receiver.
Option 1: This is about the minimum cost and performance you
would need to operate your Lucas Oil.

PLEASE READ THESE NOTES ABOUT USING LIPO
BATTERIES IN YOUR BOAT
The Lucas Oil uses the AquaCraft 60A motor controller. This
controller 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 and will not allow
you to re-arm the power system until the battery power is cycled.
With that in mind, 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.
GrimRacer says, “It’s best to test this by making a
timed 2 minute run, charge the batteries back up and
note the amount of mAh the pack allowed back in.
Do this each and every time you make a prop change
or any other significant 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 and in turn causing short pack
life. We highly recommend the use a dedicated marine LiPo pack
like those in the AquaCraft GrimRacer line.
NOTE: Transmitter (shown) and Receiver (not
shown) are not included with the Rx-R model.

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 Lucas Oil has flotation added to the interior
of the hull and the cowl. They will not sink. To aid you
in retrieving a stalled RC boat one can use a fishing 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 closeattention toitems suchasloose 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.
This boat is controlled by radio signals, which can be susceptible
to interference from other RF sources. It is a good idea to pre-
check the radio 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-flowing bodies of
water such as creeks or rivers.

RECEIVER READY (Rx-R)
RADIO INSTALLATION
Listed here are a few great radios to choose from for your receiver
ready (Rx-R) Lucas Oil.
1
Tactic TX240 (TACJ0245). The TX240 radio system is reliable
and easy to operate. It’s basic but has all the necessary
features to operate your Lucas Oil.
2
Futaba 3PMS (FUTK2021). This radio system is very reliable
and offers more operator options. We really like the timer
option this radio system offers as well as the multi model memory.
3Futaba 4PL (FUTK1400) Along with great reliably this radio system offers the most user options. It’s also a great system
if you want to add to your AquaCraft boat collection. This system
offers 40 model memory and 10 character naming; great features
to grow your boat lineup.
NOTE: This step will require working on the boat with the radio
turned on and power to the motor. To prevent any possible injury
temporarily remove the propeller from the boat.
Mount your receiver in your boat by installing hook and loop to
the bottom of your receiver.
Plug the steering servo into channel 1 of the receiver and the
motor controller into channel 2.
Turn on your transmitter.
Set the Throttle Trim to negative (clockwise if you have a dial) 25%.
If your radio has end point adjustments, check to see that
you’re (EPA) is set to 100% both forward and reverse throttle
trigger. Then proceed to “arming your system”.
START UP AND OPERATION
Install 4 AA batteries into the transmitter using the installation
pattern molded into the bottom of the battery tray.
Turn on the transmitter, making sure it’s working by viewing the
LED on the front. The LED should glow bright red.
Remove the canopy and install the provided hook and loop
material to your battery packs. Install the batteries, making sure
they are well seated.
Stand clear of the propeller and plug each of the battery packs
into the motor controller.
At this time you will hear one beep. To arm the system, squeeze
the throttle trigger of the transmitter and hold until you hear one
more beep. Release the throttle trigger and you will hear three
more beeps. NOTE: You will have to go though this simple
arming procedure each time to run your boat.
If your boat does not beep after plugging in the batteries, turn
the throttle trim knob either left or right until you hear the boat
beep (the trim knob in the 2 o’clock position is typical). Then,
continue the arming process.

REVIEW Plug in the packs -> One (1) beep
Squeeze the throttle trigger and hold -> One (1) beep
Release the trigger -> Three (3) beeps
Now is a good time to check the rotation of the prop. Quickly
squeeze the throttle trigger and check the direction of the motor.
It should spin the propeller counterclockwise when viewing the
boat from the back. If the motor spins the wrong way, simply
switch any two of the three wires between the motor and the
controller. WARNING: Do not hold the throttle down for more
than one or two seconds to check the motor direction or
you might risk damaging the motor. Also check the steering
direction. When you turn the wheel to the right, the back of the
rudder blade should also move to the right.
Install the cowl and tape in place. You are now ready to run the
boat. After you have completed your run, bring the boat in, un-
tape and unplug the batteries. Be careful as electronic parts
can become very hot during operation. Allow the electronics
to cool before running the boat again.
TIPS AND NOTES
The handling and performance of your Lucas Oil can be disrupted
by the smallest obstructions in the water. If you happen to pick
up a small duck feather or leaf, the power system could draw
more current than the motor or controller is capable of handling;
the performance of the boat will be compromised and you could
damage the motor, controller or batteries. Please make sure the
water you are running in is clear of obstructions.
It’s also important tonote that if you operateyou boat for extended
periods of time at less than full throttle, you could overheat the
motor controller. Be mindful of this as you operate the boat.
PLEASE READ! Your Lucas Oil features a rudder blade water
inlet. This system offers the most speed and least drag. In RC
boat racing, our boats race in a clockwise manner; having said
this, it is important to make the majority of your turns to the right.
You could damage the motor or controller by continually turning
left. NOTE: Because of prop torque, our models turn best
clockwise (right). Your lap times will be lower when running and
racing in a clockwise pattern. If you still feel you would like to
mount a water pickup on the transom, a Transom Mount Water
Pickup (AQUB9520) will allow you to do so.
MAINTENANCE
MOTOR CARE
After each day of operation we feel it’s best to remove the motor
and flush it out with a moisture displacer and re-oil the shaft
bearings. You are going to need the following tools and supplies.
12mm Open End Wrench
10mm Open End Wrench
2.5mm Hex Wrench
Water Displacer (WD-40, CRC-56 or Corrosion X)
Bearing Oil
Paper Towel
Start by removing the water lines to the motor jacket.
Unplug the three 4mm connector leads to the motor.
