Cool! Downloaded and activated but I have one (BIG) problem. In the F10 view I can not go to first person view  for ground vehicles. I only get a binocular button in the toolbar above, not the  small tank-like button. I put in the mission editor an A-10 (AI or player controlled) and an M1 Abrams and selected "Pilot can control vehicle". What am I forgetting?   
Edit: after so much lurking I didn't even realize it is my first post; Hi everybody!   
Edit2: Perhaps wrong DCS World version... upgrading...
