2) Do not fly close to people, buildings, or high-voltage power lines;
3) Make sure that your radio equipment works as intended, your control surfaces turn in
the right directions, and your batteries are properly charged;
4) If you are inexperienced in RC flying, have someone experienced to help you;
5) Please remember that you are the one who is responsible for all aspects of your model
plane flying. Your flying enjoyment relies on safe flying.
