I do not think the problem is the simulation, more likely that joystick driver. Make sure you have the drivers in accordance with your OS 32bit or 64bit). For example, I try the newer drivers for Win 7x 64 but, when I try to change profile over Clutch (I) button it doesn't work well. In addition, the X52 is best to have SST_Software_64_6_6_6_9. Here, try this my profile. I took from somewhere (perhaps the 6S.Duke) profile and added some commands and adjust to my liking. I still have some changes so that profile is WIP, so you're gonna have something to change, and adapt to your taste.
I would like if someone made a (YouTube) video tutorial with narration (or subtitles) showing the flight controls, and parameters to perform basic aerobatic maneuvers: loop, barrel roll, split-S, etc.. :joystick: But this, so far, no one has done. P-51_Mustang.rar
