I'm having difficulties connecting the Mavic to my useless "phablet". This means that although I can fly the thing I can't see squat on the screen. Some more Googling required.
I did take the opportunity to try the 1/32,000 sec' shutter speed that the A9 sports. The propellers are rotating at around 8,000 rpm and are about 16cm diameter, so them blades are shifting. You can see quite a bit of mess around the props' but still, most impressive for a FF camera.
