Why do you think I am "pissed" at you? AFAICT there's not even a question about polarity, let alone a pissy question. > If you really do not have > any literature to share with us, just say (write) so. 1) I am traveling right now. I am away from my books. But I remain confident that the books say what I said they say. 2) There was one brief misunderstanding, but I thought that was cleared up with help of Jon Berndt, so I thought there was no need for literature or for additional clarification. 3) I consider this misunderstanding trivial, because the ideas and the code remain the same; only the wording of my explanation needed to change. 4) I have already apologized once for this brief and superficial misunderstanding.

Note that the FG properties /controls/flight/rudder /controls/flight/elevator /controls/flight/aileron pertain to cockpit controls, not to "control surfaces" directly. If anybody thinks that these properties are conventional as to polarity, please say so. I have not yet heard anyone say that they are. Unless/until I hear that there actually is a issue here, I will assume there is no issue, and no need for me to cite literature or say anything more. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
