How far up would you like to go? If you have the budget, I would get a .50 size nitro heli, buy a good radio, join a club, and go out and have a blast. That route will cost you around $1200 give or take. (you can find good used stuff for less) Or you can go buy a Blade 450 for around $400 I think. It's a small electric that comes with a radio. With a little setup you could be in the air quickly. No matter what you do, please join an RC club and get help so you don't crash on your first hover. Also flight simulators are really nice to learn on, and they are perfect for the winter months when it is too cold to be outside.
GOOD LUCK!!!!
