Safety, Precautions, and Warnings
As the user of this product, you are solely
responsible for operating it in a manner that
does not endanger yourself and others or result
in damage to the product or the property
of others.
Carefully follow the directions and warnings for
this and any optional support equipment (chargers,
rechargeable battery packs, etc.) that you use.
This model is controlled by a radio signal that
is subject to interference from many sources
outside your control. This interference can cause
momentary loss of control so it is necessary to
always keep a safe distance in all directions around
your model, as this margin will help to avoid
collisions or injury.
• Always operate your model in an open area away
from cars, traffic, or people.
• Avoid operating your model in the street where
injury or damage can occur.
• Never operate the model out into the street or
populated areas for any reason.
• Never operate your model with low transmitter
batteries.
• Carefully follow the directions and warnings for
this and any optional support equipment (chargers,
rechargeable battery packs, etc.) that you use.
• Keep all chemicals, small parts and anything
electrical out of the reach of children.
• Moisture causes damage to electronics. Avoid
water exposure to all equipment not specifically
designed and protected for this purpose.
General Guidelines
It is important that you read and follow this
instruction manual, along with the JR® XR3i radio
system manual and the Zenoah® G26 engine
manual, before you run this exciting boat. Failure
to read and understand the manual could result
is personal injury, property damage or permanent
damage to your boat! It is also important to run
your boat responsibly. With proper care and
maintenance, you will be able to proudly enjoy your
Formula Hydro for many years to come.
This boat has been designed to race in an oval path,
just like its full scale counterpart. At high speeds
do not attempt turns to the left, as the boat may
become unstable. If you have to turn left, do so in a
large diameter turn and at slow speeds.
When operating the boat, stay clear of people,
full-scale boats, stationary objects and wildlife. It is
preferable to operate the Formula Hydro in low
wake, low wind conditions and in areas free of
people, wildlife and objects.
Before you operate your model, make sure that
your frequency is clear. If someone is operating on
the same frequency, both models could go out of
control, possibly causing damage to the models or
to others. Check all of the hardware, manifold, pipe
and propeller for security before and after each run.
If at any time while operating your model you
sense any abnormal function, end your operation
immediately. Do not operate your boat again until
you are certain the problem has been corrected.
Always stay clear of the propeller.
