I am learning to fly both airplanes and helicopters. I will say that the heli is a whole different animal, if you've never flown one before. Where an airplane can be made to aerodynamically self-correct, there is no such thing with helis. You have to move the sticks all the time. Most A.P. helicopters have a second person controlling the camera for this reason. If you want something a bit more automated, you would have to invest in a stabilization system that can hold the heli in a hover at a constant altitude while you control the camera.
If you want something that will work extremely well out of the box, definitely look into the Bergen Observer mentioned above. It uses two-stroke fuel like a line trimmer or chain saw. One tank will last 20-30 minutes depending on the weight carried.
