You don't need a global shutter to get rid of the prop totally.
I can upload a video showing the G10 at 1/120 and it is perfect.
Got the last of the "95% bollox" JAA-crap IR exams tomorrow so won't do it tonight (need to edit away some irrelevant stuff which makes it very long).
Global shutters are desirable for different purposes, where you have object motion relative to the camera and you are trying to avoid artefacts on the moving object while showing the moving object. To get rid of the prop in flying videos, you just need a slow shutter speed, which means you need a camera which has a means of selecting that. You are not trying to show the prop at all.
