I'm hoping to find out more from all of you. I suppose the "ultimate" performance would be "symmetrical in every axis with no coupling".

My first instinct would be to put both the wing and stab on the thrust line, since so many maneuvers are done inverted, and we want the same response. I would think that with most pattern-proportioned ships, the stab wouldn't be affected by the downwash from the wing. BUT... There are so many good designs (i.e. "Summit" series, vs. "PTX Vector" vs "Angel's Shadow", vs. ZN Line products) with different setups that all apparently work.

If any of you know the forces involved, (some aerodynamic, some related to mass forces, as Ollie stated) or have done your own research, please share some info with me!

Thanks again, everybody.
