Hi Innis,

I just sent my MD11 files to Erik, so hopefully they show up in  CVS one of 
these days. I haven't done any _systematic_ testing yet, so I can't confirm 
whether or not the 850 units value is the absolute cut-off or not, but moving 
both CoG and Main gear forward to less than 850 unit solved the 
initialization problem for me. :-)

Now, does moving the CoG forward impact anything at all? I can imagine that it 
doesn't when we move everthing else forward too, by the same number of units, 
but I'm still unfamiliar enough to be completely wrong here. Moving just the 
CoG and the main gears didn't really seem to impact the feel of the flight 
model though. 

Just out of curiousity: Did you also use aeromatic to generate your MD-11 
config file, or did you build it manually. I saw similar, but slightly 
different values in your config file, compared to the ones I got from 

Speaking of a 3D model, yeah, it would be cool to stitch in a FS98 model until 
we have a decent native GPL'ed model. I've never done this though, so some 
useful tips would be more than welcome. :-)
