It's just an unusually smooth example of frame rate synch
not convinced by that - although she could guide me anywhere, anytime, the end of that vid when she starts the rotors has a much faster blade passing rate than the alleged airborne with guys on the skids video.
I think we have all seen lots of video footage of helos with varying effects on the rotors but that first one is unlike any others I have seen. Usually the frame rate can make it look like the rotors are turning the wrong way or standing still but moving that slowly?????? Maybe a video guru can confirm or deny.
