If you want to learn to fly, the biggest thing is finding a heli that you feel comfortable with and that has good parts support at your local hobby store or online. The eflite series of helicopters are carried at most LHS and there are literaly hundreds of places that offer factory and aftermarket parts. Their Blade CX is an excellent beginner model that is very very stable but cannot be flown outside because it does not like wind. If you step up a bit to a single rotor heli with collective pitch, such as the blade CP or CP Pro, you will have a more unstable helicopter that will be harder to learn on but will have more capabilitites as your skills advance. It really comes down to how much you want to spend and what you would like to get out of the hobby.
