We urge you to join the AMA (Academy of Model
Aeronautics) and a local R/C club. The AMA is the
governing body of model aviation and membership is
required to fly at AMA clubs. Though joining the AMA
provides many benefits, one of the primary reasons to
join is liability protection. Coverage is not limited to
flying at contests or on the club field. It even applies to
flying at public demonstrations and air shows. Failure
to comply with the Safety Code (excerpts printed in the
back of the manual) may endanger insurance coverage.
Additionally, training programs and instructors are
available at AMA club sites to help you get started the
right way. There are over 2,500 AMA chartered clubs
across the country. Contact the AMA at the address or
toll-free phone number below:

IMPORTANT!!!
Two of the most important things you can do to
preserve the radio controlled aircraft hobby are to
avoid flying near full-scale aircraft and avoid flying
near or over groups of people.
Protect your model, yourself &
others... Follow these Important

Safety Precautions

1. Your Hobbico Sukhoi SU31 should not be
considered a toy, but rather a sophisticated, working
model that functions very much like a full-size airplane.
Because of its performance capabilities, the Hobbico
Sukhoi SU31, if not assembled and operated correctly,
could possibly cause injury to yourself or spectators
and damage to property.
2. You must assemble the model according to the
instructions. Do not alter or modify the model, as
doing so may result in an unsafe or unflyable model. In
a few cases the instructions may differ slightly from the
photos. In those instances the written instructions
should be considered as correct.
