Hi Jon,

Thank you for the feedback,  do aplologize if it sounded a bit testy.  
Not my intention, just a bit of a mild rant.  ;-)

Yes, it was a while back and it was based on the architeture 
"pre-reorganization".  The good news is that I've still been able to 
work the changes into the newer versions as they come out -- a real 
credit to you and others and the structured design you have developed in 
the code that allows for such changes and revisions.

I've just finished a first rev to both 1.0 and the CVS head versions for 
the Feb Linux show and it needs some testing.  I will send you a tar 
file of the earlier version.  One item I have in that code is some 
simple ideas and parameters to vary engine performance.  Nothing "more 
awful" than four engines running in perfect sync -- same EPR, EGT, NI, 
N2, oil pressure, etc etc.  Might also be a good way to show wear and 
tear based on  engine time, Hobbs meter, percent of time at high 
power/rpm settings, etc.

The turbine/fan engine model needs some serious peer preview on the 
thermo and rotor physics.  Has a bit of "arm waving" :-)

I'll send over a tarfile. Look at the jsbsim.cxx, FGEngine, and 
FGTurbine modules for openers.  Hope you find it useful

Regards
John W.
