Your leaving the hobby!?
YESSS!!!!!!! 
Oh whoops, did I type that?
Well, if you wanna leave the hobby then I say leave, if you want to stay then I say stay, your choice, but if I were you, take these guys' advice and get yourself a job bagging groceries or something and stick with it. While it seems like a waste of money now, later in life you can look back at your teenage years and think what a great way RC was to enjoy those years, and later in life RC will still be a great way to keep you busy in your spare time. Think of it this way, at least it keeps you from spending the money on drugs.
