Slow Motion Blades

[xunhui]

I wonder if some of our more ambitious and creative minds here might try this out? Anyone, anyone dare to give it a try?

I've filmed my Mavic Pro 1 at 1000fps on an Sony RX100 Mk4 but even that wasn't slow enough to really slow down the blades enough, I'm surprised the video above was only at 240fps.

Is that in a hover or moving?

It is in motion. In a hover (assuming no wind) the blade pitch would be constant, as the surrounding air effects both (or all blades), equally.
In motion, the blades must pitch according to whether it is advancing or retreating from the direction of flight which; happens to each blade, once per revolution.
Also if you look at the ground in frame one and throughout the video, the elevation is constant.

Yes, I realise now I was thinkiing as a ground dweller where still, relative to the ground, means still full stop.
For a copter still, relative to the ground, does not necessarily mean still relative to the air (because of wind) and to generate balanced lift the pitch would have to change as the airspeed changes as the blade rotates around the hub.
The designers of the control systems are to be admired

That would be correct.
