The PilotVR camera definitions in “cameras.cfg” are missing for both helicopters.
I stopped using that a couple of SU ago. All I do now is go in to VR, move my position where I want it to then press CTRL ALT 1 to set that position. Then I create a binding to a button on my joystick to CTRL 1 to set that position. If it ever gets out of wack, I just press the spacebar to realign.
