I just found that a positive aileron pos result in a positive roll rate -- the JSBSim version is downloaded 2 weeks ago. It run with C172 model. and I did a little change. If you can be sure that positive aileron pos would result in nagative roll rate, that must be my matter. Let me check it . thank you for your patience. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
