Yes, did you see the email I sent last night? I mentioned my mistake and added more information. Can you verify which aircraft you are flying with (which FDM?)? I see you mention the Native FDM, but it's not clear what your setup is to me. > I must say the idea of running the flight dynamics model as a > script without > need for FG sounds cool to me (an electronic/control/aero nerd in the > making) .... :-) If you are interested in running an FDM in a standalone mode by itself (which I do for testing, and other purposes), see these references: www.jsbsim.org www.jsbsimcommander.org (for control system development in JSBSim aircraft) http://jsbsim.sourceforge.net/wiki/index.php/User%27s_Manual http://jsbsim.sourceforge.net/AutomaticFlightInJSBSim.pdf Theoretically, a JSBSim script should work the same with JSBSim by itself and with FlightGear - I designed it that way for testing. But, I haven't yet tested that capability. There would be a couple of small changes needed to allow a JSBSim script to work in FlightGear. Anyhow, it works fine by itself, which is useful in a lot of circumstances. Jon ------------------------------------------------------------------------- Take Surveys. Earn Cash.
