I'm guessing your going to school if your school offers a shop class i would take any courses they offer. Nothing is better than education. Talk to friends and family you maybe surprised on what kind of help they can be. The biggest part is being patient somtimes you'll run into a hard spot that will stump you for a long time and after you figure it out you'll be thinking why didn't i think of that right away. The best advise i can offer is read all you can in these forums and surf the web they are of the biggest help to me. For the what you can do with it depends on how you make it if you make r/c planes you could design you plane on a computer and have the machine cut it out which is convient if you crash a good plane design so you can make another one or just make modification to it.
