RE: AM VS FM RANGE
Someone ahead stated you should get a flight pack. That is very sound advice. With cheap am radio's until you get the nicads and all the other stuff you will need you are at 60 to 80 bucks. A Hitec standard flight pack can be had for 100. One other point, the AM has no trainer plug. You cannot buddy box it. You also have to learn 2 ways to fly. Single stick and mode 2. So it will take longer to actually learn and become a competent pilot. I would nix the am idea and stick with your 7C. It is a fine radiop.
