Just seen dioncuda's post. Don't get one just for the sake of it! When I was your age I always wanted everyting. I loved to see the big boys play with their nitro cars. I then moved onto dreaming about planes. From the age of 10, that was all I wanted for X-Mas.

I used to go and watch them at a club for many years. Only when I was 15.5 did I get one. It cost about £300 for everything I needed. It was funded by myself. I think I sold my playstations and stuff. It was the best thing I had ever set my hands on.
I flew planes for a year, got bored and went after heli's. I ended up with a 2nd hand (probably 22nd hand) Hirobo Shuttle ZX which was about 15 years old. It got me through hovering and I could even loop it and do other aerobatics. It cost £200 for the whole setup.
If it's just RC stuff that you're interested in, start off with what you really want, it is unlikely that you will manage to get a Skydiver, car, boat, plane and heli. Start off with something like a basic plane or heli. Get all your equipment and then, when you save up some more, just buy a different model and you'll already have the gear.
Whatever you get, whether it be plane or heli, you'll love it!

Flying my plane for the first time in my life has got to be the most enjoyable thing I have ever done. The feeling you get on your first flight is pure exhilerating. I remember driving my plane around on a field and then all of a sudden the bloody thing hit a bump and took off, that was my first flight and I'll remember it for all my life cos I had been dreaming about that moment for many years before.
