Limited Warranty & Limits of Liability (cont)

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,

Limited Warranty & Limits of Liability (cont)

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.
