I just downloaded this aircraft and it looks like it might have been a total waste of money. It would appear that the mouse cannot currently be used to adjust the cockpit controls, as the mouse pointer will not go to the same level that they are on, instead it just floats in front of your face.
A post from the developer, SSG, on the aircraft's forum appears to brush it off as being VR not being stable enough, despite the fact that the developers of the other XP11 aircraft that i have downloaded, do not have this problem.
I'd steer clear of this one for now, until they figure out what the other developers have.
