Yes, four channels mean ailerons, but trust me, you will want to learn with them. The only difference is the plane uses ailerons to turn instead of the rudder, making it more responsive.

Think of it as being able to do barrel rolls when you turn the stick instead of just turning the plane into a dive.

I was scared of ailerons at first, but the first 4 channel plane with ailerons I flew was natural to me. I could never go back to a 3 channel plane, although I like taking me Easystar out to bash around.

Give serious thought to four channels. It's much mopre realistic and enjoyable.
