General Guidelines

It is important that you read and follow this

®

instruction manual, along with the JR
system manual and the Zenoah
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
Miss LLumar 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 Miss LLumar 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
