I have wondered about something similar to this as in,, settings and why some planes preform better with different stick settings than others but it could also have plenty to do with the stick itself!
I have flown enough to know that with my scale settings one way ,I fly certain planes well and others, that I used to fly well do not handle nearly as good with the new settings, I thought about making profiles for each plane, say a screen shot of each setup and the planes it serves best, then print them off and have them as handy reference material for such things as FSO or racing, I use the saitek x52 pro and pedals, if anyone thinks this is something that would be of interest we could start a thread and post your scale settings for each plane so as to compare notes and share info!
