Thanks for your help I've sorted it out.
I backed up and deleted ju87d3.svc and ju87d3_t.svc. The game re-made ju87d3.svc but not the other. I'm guessing that the second file is for the turret view as only turreted aircraft seem to have one. I used the controls to change the seat position and saved tham. I have F10 mapped to pilot head position front and also to TrackIR centre and checked that I had changed the save seat position from F10 to l-shift F10.
