forestrokes reply was probably the best put advice I've seen on RCU for the questions you asked, Especially #5. When you go to the local hobby shop or flying field don't be shy about talking to people and asking as many questions as you need. A few years ago, when I lived in Columbus, OH, a guy came to our field asking some of the same questions and I was so impressed I ended up giving him my Sig Kadet a few days later.
