AMA
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 Yak 54 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 Yak 54, 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.
3. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in first-class
condition, and a correctly sized motor and components
(battery, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components
so that the model operates correctly on the ground and in
the air.
