Oryx, the OHS planes I've seen at the SAE Aero Design West competitions hardly inspire confidence in the practicality of the configuration, if only from a structural standpoint.
Placing a potential oscillator at the end of the wing, and then out on a boom is a flutter incident begging to occur.
As for the tail lifting up. Nope!
Look at these images of U.Ill's 2002 entry.. the horizontal is keeping the nose up. always...
I'd check the math on the neutral point computations.
Moving the tail outboard doesn't do the magic thing it's claimed to do.
OHS designs are IMNSHO, exercises in futility, since the exact same result can be achieved lighter, cheaper and easier with a conventional layout.
Interesting to watch, but aeronautical dead ends.
