Is it that bad? Well, I think you can make it that bad... ha, ha. Since I'm flying it with a Fut 6XA which is the pre-mixing model radio , I'm training my thumb. I think the reason it's initially so bad is that one thinks you need a ton of rudder to knife-edge based on previous plane experience. Even my other fun-fly requires about all the rudder it has and I even enlarged it upon building. So, on the UCD, you tend to initially put a ton of it in and there she goes to the belly. Probably do a complete inside knife-edge turn if you let it. Back the thumb off the rudder and you will keep knife-edge while reducing the belly turn a bit. I'm still playing with this and convincing my head and thumb to back off that rudder... ha, ha.

<<I guess if you have to pick the worst of two evils, most like the way it flies with the aft cg and just deal with the coupling.>>

I think you're also right about that!
