I just have a small copter. So small, in fact, that it is really only good inside the house as even the operation of the heater/AC will affect it. Like Evo says, start cheap and practice.

I have had a long-time interest in RC planes. For them, owners often hire pilots as the skill needed to fly versus the investment make it worth it. So, it will be a good idea to get a model that has repair parts easily available as Stuff Happens.
