I'm trying to learn what I can about aileron reflex and am looking for some imput. I have a few questions.

1) What is aileron reflex?

2) How or when does it help with 3D flying?

3) How is it programmed ? (especially on a Futaba 9C)

I've been watching 3d pilots and it looks like some of the better ones are using aileron reflex. Is this an accurate observation?
