INTRODUCTION
Thank you for purchasing the AquaCraft
™
UL-1 Superior!
We want the time you spend with your new R/C boat to be
fun and successful so please fully read the manual. If for
any reason you think this R/C model is not for you, return it
to your local hobby dealer immediately. Your hobby dealer
cannot accept returns on any model after final assembly or
after your boat has been operated.
SAFETY PRECAUTIONS
• 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 you in retrieving a stalled R/C boat, set up a
fi shing reel with a tennis ball tied to the end of the line.
Or better yet, get yourself a small boat so you can row
out and pick up your R/C boat. Remember to use a PFD
any time you enter your retrieval craft.
• AquaCraft products are to be used by ages 14 and over.
• Do not touch the propeller anytime the motor is spinning.
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 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 are susceptible
to possible interference.
• If your UL-1 should happen to stall, water currents will slowly
carry it to shore. The bad news is that 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.
