I have mentioned this in previous posts but the frame rate capabilities of my R3s have encouraged me to play around with some more aggressive settings.  When something is a more important subject and not something I want to risk failing to get, I will be more cautious but there are plenty of other planes that I wouldn’t otherwise care about that provide a good subject to be a bit more ridiculous with.  I was going down to 1/50^th of a second shutter speed.  With this, I would go to the 30fps setting on the frame rate or even, occasionally, the 194fps setting just to see what might yield a sharp shot.  The parallax issues are going to be an issue at this shutter speed but when you are directly abeam, you can get a good outcome.  Here are some of the results from experimenting.
