You have a lot to learn with helicopters
. You can pick a few different types of helicopters to learn on depending how much control you really want of the heli. Meaning the ones easy to control usually fly themselves mechanically (coaxial), which can be fun but gets boring quickly if you want more control of the heli (how it banks, etc). With more control (fixed pitch and collective pitch helis) however, the harder it becomes. You have to actually learn to fly these models. If you want to eventually go with something bigger with aileron control I suggest you look into a pc simulator. The sim will teach you loads and you'll never out grow it. There are a few free sims but you need a transmitter or the sim won't do any good. There are also a few usb only (won't actually transmit) tx's you can buy that will connect to a computer. Most of the free sims and usb tx's aren't the best but they'll get you started. A better sim would be phoenix, at $129.
There's a lot of great info on here as well, so browse around and learn as much as you can so you know what you're getting into
