I was just about to post the same issue.
VR controllers are far too imprecise to control a rotary knob or the G1000 pan/zoom joystick. But the “Cockpit Interaction X Axis Lockable” (and y-axis) looked like the perfect solution… except they do nothing.
Thank you for posting, now I know it’s not just my setup, so I will stop fiddling with my controller settings.
When the MFS2020 was initially introduced Asobo/Microsoft somehow pitched the Reverb G2 as the best supported VR headset (it’s based on MS WMR). It’s a pity they were unable to make it right even for their own (WMR based) controller
Actually, they are very precise - in X-Plain I could rotate my wrist and adjust everything very finely: heading, trim, radio freq etc. It’s just that SU7 Asobo implementation is buggy and it’s impossible to dial in anything - see my bug post about that. If done correctly, rotating your wrist would be just fine for any control. But there’s no reason not to have both: joystick control can also be useful.
