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.
