If it wasn't for the great work on JSBsim and YASim we'd have very few
aircraft.  But I think those config files, along with the "source code" that
ends up interpreting and processing them, both make up the FDMs.  There is
considerable skill and effort involved in producing accurate flight models for
new aircraft isn't there?

Or maybe I'm just not very good at it :-)

Heh...probably the later!

Anyway,  I knew exactly what Lee meant.
