Hey toaster :-), I love your idea of trying to simulate aerobatics correctly and I'd want to try to help you once you're able to release the first version. I'm not too familiar with flightgear (I'm only using it as a flight data display) so far (especially not JSBSim, can't help you with that), but I've been flying aerobatics for quite a while (I'd rather have other people judge my skill than myself :-) and I'm quite familiar with the flight dynamics of different aerobatic maneuvres. In my opinion simulating the wings seperately would be the key feature for simulating aerobatics. No simulator I know of has this ability so far, but accurate (inverted) snaps and spins won't work without it. You'll also have to include the torque effect since in modern aerobatics many figures rely on engine torque influence, and vice versa many figures simply won't work with or without it. In the end, I don't believe we even have an aerobatic plane for Flightgear yet (I'm loading MS Flight Simulator MDL-models). I don't know if I can help you out, but I'll try!
Good luck on your design, TH flying.toaster wrote: > Using derivations very similar to those described by Jon in his latest paper, > I have managed having my Su-26 alpha model do most of these figures : > > http://aerobatics.ws/acro_figures.html > > The ones that still are a little "dirty" for me are the tailslide and sided > loops (the former because I always seem to have some sideslip even with > engine shut, the latter because I am plain bad as a pilot ;o) ).
