First of all, it is unwise to buy something really fancy for a first heli. You will need to learn to fly without video, before you attempt to use video. The fastest way to learn to fly is to buy a computer simulator like the RealFlite G2. Once you have mastered the simulator, and it isn't easy or instant, then you should get a heli that you can afford to beat up while you get used to flying the real thing. By the time that you have completed all of that, you will already know the answers to the question you posed here.
