Hi Kevin,
I'm not sure where the vertical location of the CG of the WindRyder is exactly, but if it is not on the thrust line, it is not far off it. During the development stages I would try to induce oscillations about the pitch axis (try real hard actually), with radical pitch control inputs at every possible throttle setting. This never caused any unexpected motion or oscillation. If the thrust line is off, the size of the horizontal stabilizer obviously compensates, and there is no reason to change anything in that area. Now if you were to ask me about vertical stabilizers and yaw stability, I would be more than happy to provide you with some very informative stories that are guaranteed to cause any reader some serious mirth.
