Nice sleuthing. But I'm still not convinced that 1/30,000 is the fastest/shortest.
Look at the shadow on the ground too. The tail rotor's shadow is 90 degrees to its true position in the photo. Caused by the HUGE
Nice rubber helicopter!
I agree that the speeds are probably higher. In some tests on my A570, I was able to somewhat verify a 1/64,000 shutter speed. I took a series *identical* photos (yay scripting) with halving shutter speeds of an outside window on a bright day. I then checked each phot against the next one to see if it got dimmer (should get ~1/2 as bright). Of course there is a limit to the difference I can percieve with my eye, so at the faster shutter speeds, I used frame subtraction (I'm using HDR Shop because it lets me bump stops up easily) and looked at the result. Ideally, the differenced image should be of equal brightness (approximately) to the faster shutter speed (because I was using full stops, 1/2 shutter speed steps = 1/2 brightness, 1 - 1/2 = 1/2). I the frames are equal, ideally you should be left with a black image. This is all discounting the noise of course. But I was able to get a discernible difference between 1/32000 and 1/64000, beyond that, the relative noise was getting brighter than the image. Perhaps not the most scientific testing method, but it seemed to do the trick in the absence of more sophisticated equipment.
