Xoom, I am in the absolutley exact same position as you. I am 15 going into my sophmore year and spending all of my money on airplanes. Not only that but i have begun to slack off in school due to the amount of times im spending on the hobby, hense the screen name. My view on my situation is that i am going to have to down scale my participation in the hobby and really budget my money per month as well as my time. I also want you to know that a very good friend of mine that goes to MIT still finds a vast majority of time to work on his planes and helis from his tiny dorm. Also college doesent mean no airplanes, I was recently working with a mit proffessor and students on an airforce sanctioned project related to model airplanes involving autonomous flight by gps. It may not be 3D but we all got a couple of flights in on my foamie.

send me a PM if you want to talk more about it, there is a serious lack of kids our age in the hobby.
