Tim,
I'm running the 160 DZ with the APC 18.1x10.1W. It's a great setup (until the DZ gets fussy and throws the prop off...)

The plane has right thrust built into it for certain. I'm finding that the CG doesn't have much of an effect on the performance. I also did a little fussing with the thrust and don't think it plays much of a roll as everyone thinks with these big wide body planes....
