Thanks for the video, Savoia. I've seen that one also. It's very fascinating and it's amazing to think how fast the old film camera must have been spinning! Must have been some kind of custom rig.
I am asking about the machine being on the ground, shut down, with the blades slowly rotating around it so show a 360 degree view. Would make a great part of a company's promo video!
misterbonkers, your understanding is correct. Exactly what I was hoping to see on different types! Hope someone could have a go at making one!
