I'm curious what it looks like. I will do in the next days also for test flights needed, to recieve some feedback, let's hope good one :)) I still have some troubles getting right values of DPI gain with pitch, but much better than before, only finetuning needed. As I saw on other topic, stopping the Integrator if fltctl is in saturation, this good idea has to bee added too. I'll also have/want to modify the Rollrate controll, because this is made w/o a D component, maybe I'll get better results with one. If you want I can post the Bank-Attitude-Hold to see some structure how my FDM-components work together. I'm still in Office, but as soon as I'm home I'll post some parts. markus _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
