I downloaded the cat extractor and changed the MaxYaw and MinYaw in my HUNTER9_COCKPIT.INI and indeed I can now check my six. I use 230 and -230 which seems to work fine. Changed MaxPitch to 180 so I can look behind that way as well .. just to test it out. Below are my settings.

Sadly for the F14 it doesn't work that well. You look straight through the 3d-model when you turn your head.
