I'm finding the same problem, the default head position is to high and to the left, also to far back. My head is going through the pilots head rest and preventing me seeing the cockpit dials and front view and when I switch to the navigators view it's well screwed and I can't see the fuel valves. It's fine in all my other aircraft. I use track hat and a 2d screen , not a fan of vr can't stand a box being fixed to my face.
