On this flight I did not have head tracking on. In fact, I invited a 90 year old friend who is a decorated Vietnam veteran to watch the flight with the goggles. He sat in a chair in the pits where he could not fall. His vision is poor but could see the screen in the video goggles. I am using the DJI air unit and DJI goggles 3:

I am not getting the response I wanted in the airspeed indicator. I will probably change it to an AOA indicator.

I got the airspeed to work this weekend and was able to make some changes today. The changes open up the range of motion:
