I feel the same at times, 20 minutes seems forever and glad it lands safely. Other times it's,
"Wow! It's way up there getting slapped by the wind and it might fall!" Sometimes I get dizzy watching the screen too, but I have gotten airsick prior to becoming a real plane pilot where that matter subsided as the aviation doc said a lot of pilot's do once they are in control of the plane and they loose that feeling for some reason. Maybe time will make me more comfortable as with normal aircraft. How much time is the unknown. Regular pilot's license was 40 hours in the air, so maybe 80 flights of the drone to become comfortable with them too? That and trying to get some faith in these things where too many glitches often occur at times which is unsettling. If the number of drone glitches occurred in a regular aircraft I would have stopped flying those real things long ago.
I got a laugh out of someone who put FPV goggles on someone for a "Pilot's seat view" from a racing drone's perspective. They got nauseous too, and were standing on their toes at times yelling like the earth had left them or they were going to hit something. Flying 85 MPH through a racing drone's obstacle course is unsettling, unless one is some super-proficient gamer or something.
