You betcha. Ain't no difference at all. Well, not exactly, there can be
differences due to the abilitly to align the thrust axis with the CG, or
the location of any control surfaces and their relation to the CG, or the
location of the CG... But pendulum's have nothing to do with it.



I'm not buying it.



I'm skeptical too.

Unlike the huge gyroscopic forces on a helicopter rotor this thing has
two puny ducted fans. Good thrust efficiency, but not much stabilizing
force.

In addition, there are two fans - side by side.
I believe the torque reactions would be in fore/aft pitch.

Hmm?
