I'm not completely clear on it, but I've been told that X-Plane can
calculate some of the derivatives for you.  It calculates those
depending on shape and design of your aircraft.  How it does it is by
magic.  So I would let X-Plane calculate some of the derivatives, and
then verify those numbers by plugging it in Flightgear and comparing
performance.   Just a thought!
