New futaba 9C
I think the radio compares much more to the 8u with easier programming.
I have both, although I have not flown with the 9c, the basic programming seems much easier. I was able to get into the menu, and fiddle with it for a while. I think I could do a basic airplane setup without looking at the manual.
As to the advanced mixing, etc, I'm not sure if they are easier or not.
I do really like the feel of the sharp control sticks of the 9c over the 8u. I believe they are the same sticks from the 9z.
