Bruce,
I don't think that I will be pushing the NP that far back unless I really cantilever the tail surfaces back....
Where I am using a symmetrical airfoil for the tail planes I can adjusted the AOI of the stabilators as needed. (at least that is the hope)

I am gathering up the bits to try a smaller scale (1/4 the size of my original) EDF version for testing.

A friend forwarded me a copy of a recent story from issue of MAN, where someone had built a Turbine powered aircraft with vectored thrust. Now he had only up-down in the vectored thrust system and only used it after takeoff. It seemed to have limited throw as far as the vectoring system but it was a far more conventional airframe. I was wondering if anyone who has built or flown that airplane what the effect of the vectored thrust system was to them, and what type of deflection were set up for.
