Mr. Jerryk from Kentucky- Well, belonging to AMA puts you in an organization that has been advancing model aviation since 1936 and who are responsible for all the radio frequencies we have available today. They also put out a world class magazine, Model Aviation, which is filled with helpful ideas. Last but not least, they provide you with legal liability insurance that you definitely need in the litigous society we live in today. You can drive a relatively short distance and visit our headquarters and flying site in Muncie, Indiana. This is a great experience.
But, I would recommend you join an RC flying club where you can experience the fellowship and flight instructors who will help you get started, deciding what equipment to buy and what models to learn on. Instructors often use "buddy boxes" which all but rules out your crashing a model in your early months of learning.
AMA puts you in the world of aviation and the clubs teach you to fly.
And, as recommended, look up AMA on their web site for the rest of the story.
