>but the two channel thing is whipping me.

It's the way the radio microprocessor ("computer") is set up. From the programming menu you select the "dual servo" option and plug one servo into channel 1 and othe other into (typically) channel 6. The radio has a programmed mix to operate one aileron servo from channel 1, the other aileron servo from channel 6.
No understanding needed, it's just the way the transmitter is designed.
